| Business Description and Basis of Presentation | 1. Description of Business and Basis of PresentationNeuroMetrix, Inc., or the Company, a Delaware corporation, was founded in June 1996. The Company is a medical device company focused on the diagnosis and treatment of the neurological complications of diabetes. The Company believes that its substantial experience in developing medical devices to stimulate and measure peripheral nerve function uniquely position it to address unmet medical needs related to diabetic neuropathy. Neuropathy is a common and serious, often painful, complication of diabetes that may lead to foot ulcers and limb amputation. The Company has over a decade of experience in neuropathy detection starting with approval in 1998 by the United States Food and Drug Administration, or FDA, of the NC-stat System, a point-of-care device for the performance of general purpose nerve conduction studies. The Company currently markets products for the detection, diagnosis, monitoring and treatment of diabetic neuropathies such as diabetic peripheral neuropathy and median neuropathy (carpal tunnel syndrome). The Company launched NC-stat DPNCheck in late 2011. NC-stat DPNCheck is a fast, accurate, and quantitative nerve conduction test for diabetic peripheral neuropathy designed to be used at the point of care. Sales efforts for NC-stat DPNCheck are currently targeted at opportunities in the managed care market. In the first quarter of 2013, the Company completed product development and launched the SENSUS pain management system which is designed for relief of chronic, intractable pain. The Company believes this product will be attractive to endocrinologists, podiatrists, primary care and other physicians that are challenged with trying to manage pain in their patients with painful diabetic neuropathy. The Company’s historical neurodiagnostic business is based on the ADVANCETM NCS/EMG System, or the ADVANCE System, which is a comprehensive platform for the performance of traditional nerve conduction studies and invasive electromyography procedures and which is primarily used in physician offices and clinics. The ADVANCE System contributes the majority of the Company’s revenues. The Company held cash and cash equivalents of $8.7 million as of December 31, 2012. The Company believes that these resources and the cash to be generated from expected product sales will be sufficient to meet its projected operating requirements for at least the next twelve months. The Company continues to face significant challenges and uncertainties and, as a result, the Company’s available capital resources may be consumed more rapidly than currently expected due to (a) decreases in sales of the Company’s products and the uncertainty of future revenues from new products; (b) changes the Company may make to the business that affect ongoing operating expenses; (c) changes the Company may make in its business strategy; (d) regulatory developments affecting the Company’s existing products and delays in the FDA approval process for products under development; (e) changes in the Company’s research and development spending plans; and (f) other items affecting the Company’s forecasted level of expenditures and use of cash resources. Accordingly, the Company will need to raise additional funds to support its operating and capital needs beyond the next twelve months. The Company may attempt to obtain additional funding through public or private financing, collaborative arrangements with strategic partners, or through additional credit lines or other debt financing sources to increase the funds available to fund operations. However, the Company may not be able to secure such financing in a timely manner or on favorable terms, if at all. Furthermore, if the Company issues equity or debt securities to raise additional funds, its existing stockholders may experience dilution, and the new equity or debt securities may have rights, preferences and privileges senior to those of the Company’s existing stockholders. If the Company raises additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to its potential products or proprietary technologies, or grant licenses on terms that are not favorable to the Company. Without additional funds, the Company may be forced to delay, scale back or eliminate some of its sales and marketing efforts, research and development activities, or other operations and potentially delay product development in an effort to provide sufficient funds to continue its operations. If any of these events occurs, the Company’s ability to achieve its development and commercialization goals would be adversely affected. Certain prior period amounts have been adjusted to reflect the Company's 1-for-6 reverse stock split of its common stock completed on February 15, 2013 (see Note 15, Reverse Stock Splits, for further details). |

| Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Use of Estimates and Assumptions
The preparation of financial statements in conformity with United States generally accepted accounting principles requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during reporting periods. Actual results could differ from those estimates.
The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances and regularly assesses these estimates, but actual results could differ materially from these estimates. Effects of changes in estimates are recorded in the period in which they occur.
Cash and Cash Equivalents
The Company considers all highly liquid investments with an original maturity of ninety days or less to be cash equivalents. Cash equivalents are recorded at cost which approximates fair value. The Company invests cash primarily in a money market account and other investments which management believes are subject to minimal credit and market risk.
Concentrations of Credit Risk
Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents in bank deposit accounts and trade receivables. The Company invests its funds in highly rated institutions and limits its investment in any individual account so that they do not exceed FDIC limits. The Company has not experienced significant losses related to cash and cash equivalents and does not believe it is exposed to any significant credit risks relating to its cash and cash equivalents.
At December 31, 2012, one customer accounted for 11.5% of accounts receivable. For the years ended December 31, 2012, 2011, and 2010, no single customer accounted for more than 10% of revenue.
The Company relies on in-house assembly and three third-party manufacturers to manufacture the major portion of its current products and product components. The disruption or termination of the supply of these products or a significant increase in the cost of these products from these sources could have an adverse effect on the Company’s business, financial position, and results of operations.
Inventories
Inventories, consisting primarily of purchased components, are stated at the lower of cost or market. Cost is determined using the first-in, first-out method. The Company writes down inventory to its net realizable value for excess or obsolete inventory.
Fair Value
The carrying amounts of the Company’s financial instruments, which include cash equivalents, accounts receivable, accounts payable, and accrued expenses approximate their fair value at December 31, 2012 and 2011.
Revenue Recognition
The Company recognizes revenue when the following criteria have been met: persuasive evidence of an arrangement exists, delivery has occurred and risk of loss has passed, the seller’s price to the buyer is fixed or determinable, and collection is reasonably assured. Revenues associated with the sale of the ADVANCE devices to customers and distributors are recognized upon shipment, provided that the selling price is fixed or determinable, persuasive evidence of an arrangement exists, collection of receivables is reasonably assured, product returns are reasonably estimable, and no continuing obligations exist. The revenues from the sale of an ADVANCE communication hub together with access to NeuroMetrix information systems are considered one unit of accounting and deferred and recognized on a straight-line basis over the estimated period of time that the Company provides the service associated with the information systems of three years. The resulting deferred revenue and deferred costs are presented as separate line items on the accompanying balance sheet. Revenues related to extended service agreements for the devices are recognized ratably over the term of the extended service agreement.
Revenues associated with the sale of the NC-stat DPNCheck devices are recognized upon shipment, provided that the selling price is fixed or determinable, persuasive evidence of an arrangement exists, collection of receivables is reasonably assured, product returns are reasonably estimable, and no continuing obligations exist.
Revenues also include sales of consumables, including single use nerve specific electrodes, EMG needles, and other accessories. These revenues are recognized upon shipment provided that the selling price is fixed or determinable, persuasive evidence of an arrangement exists, collection of receivables is reasonably assured, and product returns are reasonably estimable.
When multiple elements are contained in a single arrangement, the Company allocates revenue between the elements based on their relative selling prices. The Company determines selling price using vendor specific objective evidence, or VSOE, if it is available, third-party evidence, or TPE, if VSOE is not available, and best estimate of selling price, or BESP, if neither VSOE nor TPE are available. The Company generally expects that it will not be able to establish TPE due to the nature of the markets in which it competes, and, as such, it will typically determine selling price using VSOE or if not available, BESP. The objective of BESP is to determine the selling price of a deliverable on a standalone basis. The Company’s determination of BESP involves a weighting of several factors based on the specific facts and circumstances of an arrangement. Specifically, the Company considers the cost to produce the deliverable, the anticipated margin on that deliverable, the selling price and profit margin for similar parts, its ongoing pricing strategy, the value of any enhancements that have been built into the deliverable, and the characteristics of the varying markets in which the deliverable is sold.
Revenue recognition involves judgments, including assessments of expected returns and expected customer relationship periods. The Company analyzes various factors, including a review of specific transactions, its historical returns, average customer relationship periods, customer usage, customer balances, and market and economic conditions. Changes in judgments or estimates on these factors could materially impact the timing and amount of revenues and costs recognized. Should market or economic conditions deteriorate, the Company’s actual return or bad debt experience could exceed its estimate.
Certain product sales are made with a 30-day right of return. Since the Company can reasonably estimate future returns, it recognizes revenues associated with product sales that contain a right of return upon shipment and at the same time it records a sales return reserve, which reduces revenue and accounts receivable by the amount of estimated returns. Accounts Receivable
Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Accounts receivable on the balance sheet are recorded net of the allowance for doubtful accounts receivable and the reserve for estimated returns. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in its existing accounts receivable. The Company reviews its allowance for doubtful accounts and determines the allowance based on an analysis of customer past payment history, product usage activity, and recent communications between the Company and the customer. Past due balances are reviewed individually for collectibility. Account balances are written-off against the allowance when the Company feels it is probable the receivable will not be recovered. The Company does not have any off-balance sheet credit exposure related to its customers. Income TaxesThe Company records income taxes using the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax bases, and operating loss and tax credit carryforwards. The Company’s financial statements contain certain deferred tax assets, which have arisen primarily as a result of operating losses, as well as other temporary differences between financial and tax accounting. In accordance with the provisions of the Income Taxes topic of the Codification, the Company is required to establish a valuation allowance if the likelihood of realization of the deferred tax assets is reduced based on an evaluation of objective verifiable evidence. Significant management judgment is required in determining the Company’s provision for income taxes, the Company’s deferred tax assets and liabilities and any valuation allowance recorded against those net deferred tax assets. The Company evaluates the weight of all available evidence to determine whether it is more likely than not that some portion or all of the net deferred income tax assets will not be realized.
Utilization of the NOL and research and development credit carryforwards may be subject to a substantial annual limitation due to ownership change limitations that have occurred previously or that could occur in the future, as provided by Section 382 of the Internal Revenue Code of 1986, as well as similar state provisions. Ownership changes may limit the amount of NOL and tax credit carryforwards that can be utilized to offset future taxable income and tax, respectively. In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain shareholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period.
If the Company has experienced a change of control, utilization of its NOL or tax credits carryforwards would be subject to an annual limitation under Section 382. Any limitation may result in expiration of a portion of the NOL or research and development credit carryforwards before utilization. Subsequent ownership changes could further impact the limitation in future years. Further, until a study is completed and any limitation known, no amounts are being presented as an uncertain tax position.
A full valuation allowance has been provided against the Company’s NOL carryforwards and research and development credit carryforwards and, if an adjustment is required, this adjustment would be offset by an adjustment to the valuation allowance. Thus, there would be no impact to the balance sheet or statement of operations if an adjustment were required.
Management performed a two-step evaluation of all tax positions, ensuring that these tax return positions meet the “more likely than not” recognition threshold and can be measured with sufficient precision to determine the benefit recognized in the financial statements. These evaluations provide management with a comprehensive model for how a company should recognize, measure, present, and disclose in its financial statements certain tax positions that the Company has taken or expects to take on income tax returns. Research and Development
Costs incurred in the research and development of the Company’s products are expensed as incurred. Included in research and development costs are wages, benefits, product design consulting, and other operating costs such as facilities, supplies, and overhead directly related to the Company’s research and development efforts. Product Warranty Costs
The Company accrues estimated product warranty costs at the time of sale which are included in cost of sales in the statements of operations. The amount of the accrued warranty liability is based on historical information such as past experience, product failure rates, number of units repaired, and estimated cost of material and labor. The liabilities for product warranty costs of $18,629 and $32,308 at December 31, 2012 and 2011, respectively, are included in accrued expenses in the accompanying balance sheets.
Fixed Assets and Long-Lived Assets
Fixed assets are recorded at cost and depreciated using the straight-line method over the estimated useful life of each asset. Expenditures for repairs and maintenance are charged to expense as incurred. On disposal, the related assets and accumulated depreciation are eliminated from the accounts and any resulting gain or loss is included in the Company’s statement of operations. Leasehold improvements are amortized over the shorter of the estimated useful life of the improvement or the remaining term of the lease.
The Company periodically evaluates the recoverability of its fixed assets and other long-lived assets whenever events or changes in circumstances indicate that an event of impairment may have occurred. This periodic review may result in an adjustment of estimated depreciable lives or asset impairment. When indicators of impairment are present, the carrying values of the asset are evaluated in relation to the assets operating performance and future undiscounted cash flows of the underlying assets. If the future undiscounted cash flows are less than their book value, an impairment may exist. The impairment is measured as the difference between the book value and the fair value of the underlying asset. Fair values are based on estimates of the market prices and assumptions concerning the amount and timing of estimated future cash flows and assumed discount rates, reflecting varying degrees of perceived risk.
Accounting for Stock-Based Compensation
Stock-based compensation cost is generally recognized ratably over the requisite service period. The Company uses the Black-Scholes option pricing model for determining the fair value of its stock options and amortizes its stock-based compensation expense using the straight-line method. The Black-Scholes model requires certain assumptions that involve judgment. Such assumptions are the expected share price volatility, expected life of options, expected annual dividend yield, and risk-free interest rate (See Note 3 – Stock-Based Compensation and Equity).
Net Loss per Common Share
Basic net loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Unvested restricted shares, although legally issued and outstanding, are not considered outstanding for purposes of calculating basic net loss per share. Diluted net loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding during the period plus the dilutive effect of outstanding instruments such as options, warrants, and restricted stock. Because the Company has reported a net loss for all periods presented, diluted loss per common share is the same as basic loss per common share, as the effect of utilizing the fully diluted share count would have reduced the net loss per common share. Therefore, in calculating net loss per share amounts, the following shares underlying potentially dilutive common stock equivalents were excluded from the calculation of diluted net income per common share because their effect was anti-dilutive for each of the periods presented:
Warrants outstanding at December 31, 2012 were issued in the public offering completed on February 13, 2012 (see Note 14, Public Offering of Common Stock and Warrants, for further details). Warrants outstanding at December 31, 2011 and 2010 were redeemed in March 2012 in exchange for 23,127 shares of common stock. Advertising and Promotional Costs
Advertising and promotional costs are expensed as incurred. Advertising and promotion expense was $242,000, $426,000, and $256,000 in the years ended December 31, 2012, 2011, and 2010, respectively. Accumulated Other Comprehensive Items
For the years ended December 31, 2012, 2011, and 2010, the Company had no components of other comprehensive income or loss other than net loss. SegmentsThe Company operates in one segment for the sale of medical equipment and consumables. Substantially all of the Company’s assets, revenues, and expenses for the years ended December 31, 2012, 2011, and 2010 were located at or derived from operations in the United States. Revenues from sales outside the United States accounted for approximately 7% of total revenues in 2012, 6% of total revenues in 2011, and 2% of total revenues in 2010. Risks and Uncertainties
The Company is subject to risks common to companies in the medical device industry, including, but not limited to, development by the Company or its competitors of new technological innovations, dependence on key personnel, customers’ reimbursement from third-party payers, protection of proprietary technology, and compliance with regulations of the FDA and other governmental agencies.
In late 2011, the Company launched NC-stat DPNCheck, which is a fast, accurate, and quantitative nerve conduction test for the assessment of systemic neuropathies such as DPN. In early 2013 the Company launched SENSUS for the treatment intractable pain, including pain associated with diabetic neuropathy. The future prospects of the Company are closely tied to its success with NC-stat DPNCheck and SENSUS in market acceptance and growth in future revenues. Recently Issued or Adopted Accounting Pronouncements
In May 2011, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2011-04, “Fair Value Measurement (Topic 820) — Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS”, or ASU 2011-04. The amendments in ASU 2011-04 result in common fair value measurement and disclosure requirements in GAAP and International Financial Reporting Standards, or IFRS. Consequently, the amendments change the wording used to describe many of the requirements in GAAP for measuring fair value and for disclosing information about fair value measurements. The Company adopted this new guidance prospectively beginning January 1, 2012. Adoption has not had a material effect on the Company’s financial statements.
In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220) — Presentation of Comprehensive Income”, or ASU No. 2011-05. ASU No. 2011-05 requires that all nonowner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements, eliminating the option to present other comprehensive income in the statement of changes in equity. Under either choice, items that are reclassified from other comprehensive income to net income are required to be presented on the face of the financial statements where the components of net income and the components of other comprehensive income are presented. In December 2011, the FASB issued ASU No. 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05”, which defers the requirement within ASU No. 2011-05 to present on the face of the financial statements the effects of reclassifications out of accumulated other comprehensive income on the components of net income and other comprehensive income for all periods presented. During the deferral, entities should continue to report reclassifications out of accumulated other comprehensive income consistent with the presentation requirements in effect prior to the issuance of ASU No. 2011-05. The Company adopted this new guidance retrospectively beginning January 1, 2012. Adoption has not had a material effect on the Company’s financial statements. |

| Stock-Based Compensation and Equity | 3. Stock-Based Compensation and Stockholders’ EquityStock-Based CompensationDuring 2004, the Company adopted the 2004 Stock Option and Incentive Plan, as amended and restated in 2006, 2008 and 2009. At the Annual Meeting of Stockholders held on May 14, 2012, the stockholders of the Company approved the Company’s Fourth Amended and Restated 2004 Stock Option and Incentive Plan (the “2004 Stock Plan”), which, among other things, increased the number of shares of the Company’s common stock authorized for issuance thereunder by 166,667 shares. The 2004 Stock Plan, among other things, provides for granting of incentive and nonqualified stock option and stock bonus awards to officers, employees and outside consultants. Outstanding options under the 2004 Stock Plan generally vest over three or four years and terminate 10 years after the grant date, or earlier if the option holder is no longer an executive officer, employee, consultant, advisor or director, as applicable, of the Company. As of December 31, 2012, 276,279 shares of common stock were authorized for issuance under the 2004 Stock Plan, of which 9,272 shares had been issued, 47,907 shares were subject to outstanding options at a weighted average exercise price of $72.06 per share and 176,882 shares were available for future grant. During May 2009, the Company adopted the 2009 Non-Qualified Inducement Stock Plan (the “2009 Inducement Plan”). The 2009 Inducement Plan is intended to encourage and enable employees, including prospective employees, of the Company upon whose judgment, initiative, and efforts the Company largely depends for the successful conduct of its business to acquire a proprietary interest in the Company. The 2009 Inducement Plan, among other things, provides for the granting of awards, including non-qualified stock options, restricted stock, and unrestricted stock. As of December 31, 2012, 13,889 shares of common stock were authorized for issuance under the 2009 Inducement Plan, of which no shares had been issued, 2,083 shares were subject to outstanding options at a weighted average exercise price of $9.60 per share, and 11,806 shares were available for future grant. The exercise price of each stock option issued under the 1996 and 1998 Stock Plans was specified by the Board of Directors at the time of grant. The exercise price of stock options awarded under the 2004 Stock Plan and the 2009 Inducement Plan may not be less than the fair market value of the common stock on the date of the option grant. For holders of more than 10% of the Company’s total combined voting power of all classes of stock, incentive stock options may not be granted at less than 110% of the fair market value of the Company’s common stock at the date of grant and for a term not to exceed five years. In June 2004, the Company adopted the 2004 Employee Stock Purchase Plan (the “2004 ESPP”). All of the Company’s employees who had been employed by the Company for at least 60 days and whose customary employment is for more than 20 hours per week and for more than five months in any calendar year were eligible to participate and any employee who owned 5% or more of the voting power or value of the Company’s stock was not eligible to participate. The 2004 ESPP authorized the issuance of up to a total of 10,417 shares of the Company’s common stock to participating employees. In May 2010, the Company adopted the 2010 Employee Stock Purchase Plan (the “2010 ESPP”). The 2010 ESPP initially authorized the issuance of up to a total of 6,945 shares, of the Company’s common stock to participating employees plus an annual increase on the first day of each of the Company's fiscal years beginning in 2011, equal to the lesser of (i) 6,945 shares, (ii) 1 percent of the shares of common stock outstanding on the last day of the immediately preceding fiscal year, or (iii) such lesser number of shares as is determined by the Board. At the Company’s Annual Meeting of Stockholders held on May 14, 2012, the stockholders of the Company approved the Company’s Amended and Restated 2010 Employee Stock Purchase Plan (the “Amended and Restated 2010 ESPP”), which, among other things, increased the number of shares of the Company’s common stock authorized for issuance thereunder by 16,667 shares. All of the Company’s full-time employees and certain part-time employees are eligible to participate in the Amended and Restated 2010 ESPP. For part-time employees to be eligible, they must have customary employment of more than five months in any calendar year and more than 20 hours per week. Employees who, after exercising their rights to purchase shares under the Amended and Restated 2010 ESPP, would own shares representing 5% or more of the voting power of the Company’s common stock, are ineligible to participate. Under the Amended and Restated 2010 ESPP, participating employees can authorize the Company to withhold up to 10% of their earnings during consecutive six-month payment periods for the purchase of the shares. At the conclusion of each period, participating employees can purchase shares at 85% of the lower of their fair market value at the beginning or end of the period. The Amended and Restated 2010 ESPP is regarded as a compensatory plan. For the years ended December 31, 2012 and 2011 the Company issued 8,895 and 4,090 shares of its common stock, respectively, under the Amended and Restated 2010 ESPP and the 2010 ESPP, respectively. As of December 31, 2012, there were 21,765 remaining shares to be issued under the Amended and Restated 2010 ESPP. The Company uses the Black-Scholes option pricing model for determining the fair value of shares of common stock issued or to be issued under the 2010 ESPP and the Amended and Restated 2010 ESPP. The following assumptions are used in determining fair value: The risk-free interest rate assumption is based on the United States Treasury’s constant maturity rate for a six month term (corresponding to the expected option term) on the date the option was granted. The expected dividend yield is zero because the Company does not currently pay dividends nor expects to do so during the expected option term. An expected term of six months is used based on the duration of each plan offering period. The volatility assumption is based on a consideration of stock price volatility over the most recent period of time corresponding to the expected term and is also based on expected future stock price volatility. The weighted average grant-date fair value used in the calculation of stock-based compensation expense in the accompanying statement of operations for the years ended December 31, 2012, 2011, and 2010 is calculated using the following assumptions:
The risk-free interest rate assumption is based on the United States Treasury’s constant maturity rate for a five year term (corresponding to the expected option term) on the date the option was granted. The expected dividend yield is zero as the Company does not currently pay dividends nor expects to do so during the expected option term. The expected option term of five years is estimated based on an analysis of actual option exercises and a review of comparable medical device companies. The volatility assumption is based on weekly historical volatility during the time period that corresponds to the expected option term, a review of comparable medical device companies and expected future stock price volatility. The pre-vesting forfeiture rate is based on the historical and projected average turnover rate of employees. A summary of option activity for the year ended December 31, 2012 is presented below:
Expected to vest options are determined by applying the pre-vesting forfeiture rate to the total outstanding options. Aggregate intrinsic value represents the total pre-tax intrinsic value (the aggregate difference between the closing stock price of the Company’s common stock as of December 31, 2012, as applicable, and the exercise price for the in-the-money options) that would have been received by the option holders if all the in-the-money options had been exercised on December 31, 2012. The weighted average per share grant-date fair values of options granted during the years ended December 31, 2012, 2011, and 2010 was $2.67, $11.34, and $28.44, respectively. The aggregate intrinsic value of options issued or exercised during the years ended December 31, 2012, 2011, and 2010 was $0, $0, and $3,000, respectively. Total unrecognized stock-based compensation costs related to non-vested stock options was $251,747, which related to 49,043 shares with a per share weighted fair value of $5.16 as of December 31, 2012. This unrecognized cost is expected to be recognized over a weighted average period of approximately 0.6 years. Stock options granted to non-employees are recorded at fair value and adjusted to market over the vesting period. The Company determines fair value using the Black-Scholes option pricing model, an expected term equal to the option term, a risk-free interest rate corresponding to the expected term, a stock price volatility over the most recent period of time corresponding to the expected term and also based on expected future stock price volatility, and a dividend yield of zero. There were no options granted to non-employees during the year ended December 31, 2012. Beginning in 2010, certain employees have been granted restricted stock. During 2012, 2011, and 2010, the Company granted 37,167, 3,630, and 2,616 shares of restricted stock, respectively. The fair value of restricted stock is calculated based on the closing sale price of the Company’s common stock on the date of issuance. A summary of restricted stock activity for the year ended December 31, 2012 is presented below:
During the years ended December 31, 2012 and 2011, certain employees, in lieu of paying withholding taxes on the vesting of restricted stock, authorized the withholding of an aggregate of 721 and 147 shares, respectively, of common stock to satisfy the minimum tax withholding requirements related to such vesting. Shares withheld were calculated using the market price of the common stock on the vesting dates. During 2010, certain employees received bonus payments in the form of common stock. A total of 307 such shares were issued with a total intrinsic value of $23,000. Cash received from option exercises and purchases under the 2004 ESPP and the 2010 ESPP for the years ended December 31, 2012, 2011, and 2010 was $23,000, $34,000, and $163,000, respectively. The Company issues new shares upon option exercises, purchases under the Company’s ESPPs, and vesting of restricted stock. The Company recorded stock-based compensation expense of $319,000, $837,000, and $1.2 million for the years ended December 31, 2012, 2011, and 2010, respectively. Stockholders’ EquityOn February 13, 2012, the Company completed a public offering of 1,421,735 Units at a price of $6.00 per Unit. Each Unit consists of one share of the Company’s common stock and one warrant to purchase one half of a share of the Company’s common stock. The Company issued 1,421,735 shares of common stock and warrants to purchase 781,955 shares of common stock and received offering proceeds, net of discounts, commissions and expenses, of approximately $7.4 million. See Note 14, Public Offering of Common Stock and Warrants, for further details. In March 2012, the Company issued 23,127 shares of its common stock, $0.0001 par value per share, in satisfaction of the Company’s obligation to redeem certain warrants issued by the Company pursuant to Securities Purchase Agreements dated as of September 8, 2009. No cash was paid to redeem the warrants. As of December 31, 2012, the Company had 50,000,000 shares of common stock authorized and 2,140,871 shares issued and outstanding. Each share of common stock entitles the holder to one vote on all matters submitted to a vote of the Company’s stockholders. Common stockholders are not entitled to receive dividends unless declared by the Board of Directors. At December 31, 2012, the Company has reserved authorized shares of common stock for future issuance as follows:
On March 7, 2007, the Company’s Board of Directors adopted a Shareholder Rights Plan and declared a dividend distribution of one preferred stock purchase right for each outstanding share of the Company’s common stock to shareholders of record as of the close of business on March 8, 2007. As of December 31, 2012 and 2011, there was no preferred stock outstanding. |

| Income Taxes | 9. Income TaxesCurrent income tax expense (benefit) attributable to continuing operations consists of the following for the years ended December 31, 2012, 2011, and 2010.
The Company’s effective income tax rate differs from the statutory federal income tax rate as follows for the years ended December 31, 2012, 2011, and 2010.
The Company’s deferred tax assets consist of the following:
At December 31, 2012, the Company has federal and state net operating loss carryforwards (“NOL”) of $89.4 million and $38.0 million, respectively, as well as federal and state tax credits of $1.0 million and $901,000, respectively, which may be available to reduce future taxable income and the related taxes thereon. This amount includes tax benefits of $3.7 million and $71,000 attributable to NOL and tax credit carryforwards, respectively, that result from the exercise of employee stock options. The tax benefit of these items will be recorded as a credit to additional paid-in capital upon realization of the deferred tax asset or reduction in income taxes payable. The federal NOL’s begin to expire in 2019 and the state NOL’s begin to expire in 2013. The federal and state research and development credits both begin to expire in 2018. In accordance with the provisions of the Income Taxes topic of the Codification, the Company has evaluated the positive and negative evidence bearing upon the realizability of its deferred tax assets, which are comprised principally of net operating losses. Management has determined that it is more likely than not that the Company will not recognize the benefits of federal and state deferred tax assets and, as a result, a valuation allowance of approximately and $34.3 million and $30.5 million has been established at December 31, 2012 and 2011, respectively. Utilization of the NOL and research and development credit carryforwards may be subject to a substantial annual limitation due to ownership change limitations that have occurred previously or that could occur in the future, as provided by Section 382 of the Internal Revenue Code of 1986, as well as similar state provisions. Ownership changes may limit the amount of NOL and tax credit carryforwards that can be utilized to offset future taxable income and tax, respectively. In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain shareholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period. If the Company has experienced a change of control, utilization of its NOL or tax credits carryforwards would be subject to an annual limitation under Section 382. Any limitation may result in expiration of a portion of the NOL or research and development credit carryforwards before utilization. Subsequent ownership changes could further impact the limitation in future years. Further, until a study is completed and any limitation known, no amounts are being presented as an uncertain tax position. A full valuation allowance has been provided against the Company’s NOL carryforwards and research and development credit carryforwards and, if an adjustment is required, this adjustment would be offset by an adjustment to the valuation allowance. Thus, there would be no impact to the balance sheet or statement of operations if an adjustment were required. |

| Fair Value Measurements | 11. Fair Value MeasurementsThe Fair Value Measurements and Disclosures Topic of the Codification defines fair value, establishes a framework for measuring fair value in applying generally accepted accounting principles, and expands disclosures about fair value measurements. This Codification topic identifies two kinds of inputs that are used to determine the fair value of assets and liabilities: observable and unobservable. Observable inputs are based on market data or independent sources while unobservable inputs are based on the Company’s own market assumptions. Once inputs have been characterized, this Codification topic requires companies to prioritize the inputs used to measure fair value into one of three broad levels. Fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values identified by Level 2 inputs utilize observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities. Fair values identified by Level 3 inputs are unobservable data points and are used to measure fair value to the extent that observable inputs are not available. Unobservable inputs reflect the Company’s own assumptions about the assumptions that market participants would use at pricing the asset or liability. The following tables present information about the Company’s assets and liabilities that are measured at fair value on a recurring basis for the periods presented and indicates the fair value hierarchy of the valuation techniques it utilized to determine such fair value. In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs utilize data points that are observable such as quoted prices, interest rates, and yield curves. Fair values determined by Level 3 inputs are unobservable data points for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability.

| Credit Facility | 13. Credit FacilityThe Company is party to a Loan and Security Agreement, or the Credit Facility, with a bank. As of December 31, 2012 the Credit Facility permitted the Company to borrow up to $7.5 million on a revolving basis. The Credit Facility was subsequently amended on January 28, 2013 and the amount of the Credit Facility was set at $2.5 million. The amended facility was extended, until its new expiry date of January 31, 2014. Amounts borrowed under the Credit Facility will bear interest equal to the prime rate plus 0.5%. Any borrowings under the Credit Facility will be secured by the Company’s cash, accounts receivable, inventory, and equipment. The Credit Facility includes traditional lending and reporting covenants. These include certain financial covenants applicable to liquidity that are to be maintained by the Company. As of December 31, 2012, the Company was in compliance with these covenants and had not borrowed any funds under the Credit Facility. The amount of $225,000 of the Credit Facility limit is restricted to support a letter of credit issued in favor of the Company’s landlord in the lease of its facilities in Waltham, Massachusetts. Consequently, the amount available for borrowing under the Credit Facility as of December 31, 2012 was $7,275,000 and was subsequently reduced to $2,275,000 on January 28, 2013, as noted above. |

| Stockholders' Equity Note [Abstract] | |
| Public Offering of Common Stock and Warrants | 14. Public Offering of Common Stock and WarrantsOn February 13, 2012, the Company completed a public offering of 1,421,735 Units at a price of $6.00 per Unit (the “Offering”). Each Unit consists of one share of the Company’s common stock and one warrant to purchase one half of a share of the Company’s common stock. The Company issued 1,421,735 shares of common stock and warrants to purchase 710,868 shares of common stock and received offering proceeds, net of discounts, commissions and expenses, of approximately $7.4 million. Each warrant entitles the holder to purchase at any time during the period commencing 180 days after the date of the Offering until the date five years following the closing date of the Offering, one half of a share of the Company’s common stock. Two warrants would need to be exercised to acquire one share of the Company’s common stock at an exercise price of $6.90 (115% of the aggregate offering price for a unit). In addition, the placement agent for the Offering was issued warrants to purchase 71,087 shares of common stock (equal to 5.0% of the number of shares of common stock included in the Units sold in the Offering) at an exercise price of $7.50 per share (125% of the aggregate offering price for a Unit). The placement agent’s warrants will be exercisable at any time beginning one year after the date of issuance and will expire on the fifth anniversary of the effectiveness of the registration statement related to the Offering. The fair value of the warrants was estimated at $2.4 million using a Black-Scholes model with the following assumptions: expected volatility of 73.5%, risk free interest rate of 0.85%, expected life of five years, and no dividends. The volatility assumption is based on weekly historical volatility during the time period that corresponds to the expected option term, a review of comparable medical device companies, and expected future stock price volatility. The relative fair value of the warrants was recorded as equity. |

| Reverse Stock Split Disclosure [Abstract] | |
| Reverse Stock Split | 15. Reverse Stock Splits
The Company’s common stock is quoted on the NASDAQ Capital Market under the symbol “NURO.” One of the requirements for continued listing on the NASDAQ Capital Market is maintenance of a minimum closing bid price of $1.00 per share. Because the Company’s common stock had been trading below a price of $1.00 per share, and was subject to delisting from The NASDAQ Stock Market LLC, or NASDAQ as a result, on September 1, 2011, the Company filed a Certificate of Amendment to its Restated Certificate of Incorporation, as amended, with the Secretary of State of the State of Delaware, to effect a 1-for-6 reverse stock split of its common stock, or the Reverse Stock Split. This action had previously been approved by the Company’s stockholders at the Company’s annual meeting held on May 16, 2011. As a result of the Reverse Stock Split, every six shares of the Company’s pre-reverse split common stock were combined and reclassified into one share of its common stock. No fractional shares were issued in connection with the Reverse Stock Split. Stockholders who otherwise would have been entitled to receive a fractional share in connection with the Reverse Stock Split received a cash payment in lieu thereof. The par value and other terms of the common stock were not affected by the Reverse Stock Split.
The Company’s shares outstanding immediately prior to the Reverse Stock Split totaled 23,331,646, which were adjusted to 3,888,607 shares outstanding as a result of the Reverse Stock Split. The Company’s common stock began trading at its post-Reverse Stock Split price at the beginning of trading on September 2, 2011. On September 19, 2011, the Company received a letter from NASDAQ indicating that it had regained compliance with the minimum bid price requirement under NASDAQ Listing Rule 5550(a)(2) for continued listing on The NASDAQ Capital Market. The Company’s common stock continued to be listed on NASDAQ.
On March 22, 2012, the Company received a notice from the Listing Qualifications Department of the NASDAQ Stock Market indicating that, for the last 30 consecutive business days, the bid price for its common stock had closed below the minimum $1.00 per share required for continued inclusion on The NASDAQ Capital Market under NASDAQ Listing Rule 5550(a)(2). The notification letter stated that pursuant to NASDAQ Listing Rule 5810(c)(3)(A) the Company would be afforded 180 calendar days, or until
September 18, 2012, to regain compliance with the minimum bid price requirement. On September 19, 2012, the Company received a letter from NASDAQ stating that it had been granted a six month extension until March 18, 2013 to regain compliance with the minimum bid price requirement for continued listing on The NASDAQ Capital Market. During this grace period extension, the Company’s common stock will continue to be listed on The NASDAQ Stock Market.
In order to regain compliance, shares of the Company’s common stock must maintain a minimum bid closing price of at least $1.00 per share for a minimum of ten consecutive business days. Therefore, on February 15, 2013, the Company filed a Certificate of Amendment to its Restated Certificate of Incorporation, as amended, with the Secretary of State of the State of Delaware, to effect a second 1-for-6 reverse stock split of its common stock, or the Second Reverse Stock Split. This action had previously been approved by the Company’s stockholders at a special meeting of stockholders held on December 7, 2012. As a result of the Second Reverse Stock Split, every six shares of the Company’s pre-reverse split common stock were combined and reclassified into one share of its common stock. No fractional shares were issued in connection with the Second Reverse Stock Split. Stockholders who otherwise would have been entitled to receive a fractional share in connection with the Second Reverse Stock Split received a cash payment in lieu thereof. The par value and other terms of the common stock were not affected by the Second Reverse Stock Split.
The Company’s shares outstanding immediately prior to the Second Reverse Stock Split totaled 12,845,228. These were adjusted to 2,140,871 shares outstanding as a result of the Reverse Stock Split. The Company’s common stock began trading at its post-Second Reverse Stock Split price at the beginning of trading on February 19, 2013. Share, per share, and stock option amounts for all periods presented within this annual report on Form 10-K and the amounts for common stock and additional paid-in capital have been retroactively adjusted to reflect the Second Reverse Stock Split. |

| Accounting Policies [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Use of Estimates and Assumptions | Use of Estimates and AssumptionsThe preparation of financial statements in conformity with United States generally accepted accounting principles requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during reporting periods. Actual results could differ from those estimates. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances and regularly assesses these estimates, but actual results could differ materially from these estimates. Effects of changes in estimates are recorded in the period in which they occur. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Cash and Cash Equivalents | Cash and Cash EquivalentsThe Company considers all highly liquid investments with an original maturity of ninety days or less to be cash equivalents. Cash equivalents are recorded at cost which approximates fair value. The Company invests cash primarily in a money market account and other investments which management believes are subject to minimal credit and market risk. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Concentrations of Credit Risk | Concentrations of Credit RiskFinancial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents in bank deposit accounts and trade receivables. The Company invests its funds in highly rated institutions and limits its investment in any individual account so that they do not exceed FDIC limits. The Company has not experienced significant losses related to cash and cash equivalents and does not believe it is exposed to any significant credit risks relating to its cash and cash equivalents. At December 31, 2012, one customer accounted for 11.5% of accounts receivable. For the years ended December 31, 2012, 2011, and 2010, no single customer accounted for more than 10% of revenue. The Company relies on in-house assembly and three third-party manufacturers to manufacture the major portion of its current products and product components. The disruption or termination of the supply of these products or a significant increase in the cost of these products from these sources could have an adverse effect on the Company’s business, financial position, and results of operations. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Inventories | InventoriesInventories, consisting primarily of purchased components, are stated at the lower of cost or market. Cost is determined using the first-in, first-out method. The Company writes down inventory to its net realizable value for excess or obsolete inventory. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fair Value | Fair ValueThe carrying amounts of the Company’s financial instruments, which include cash equivalents, accounts receivable, accounts payable, and accrued expenses approximate their fair value at December 31, 2012 and 2011. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Revenue Recognition | Revenue Recognition
The Company recognizes revenue when the following criteria have been met: persuasive evidence of an arrangement exists, delivery has occurred and risk of loss has passed, the seller’s price to the buyer is fixed or determinable, and collection is reasonably assured. Revenues associated with the sale of the ADVANCE devices to customers and distributors are recognized upon shipment, provided that the selling price is fixed or determinable, persuasive evidence of an arrangement exists, collection of receivables is reasonably assured, product returns are reasonably estimable, and no continuing obligations exist. The revenues from the sale of an ADVANCE communication hub together with access to NeuroMetrix information systems are considered one unit of accounting and deferred and recognized on a straight-line basis over the estimated period of time that the Company provides the service associated with the information systems of three years. The resulting deferred revenue and deferred costs are presented as separate line items on the accompanying balance sheet. Revenues related to extended service agreements for the devices are recognized ratably over the term of the extended service agreement.
Revenues associated with the sale of the NC-stat DPNCheck devices are recognized upon shipment, provided that the selling price is fixed or determinable, persuasive evidence of an arrangement exists, collection of receivables is reasonably assured, product returns are reasonably estimable, and no continuing obligations exist. Revenues also include sales of consumables, including single use nerve specific electrodes, EMG needles, and other accessories. These revenues are recognized upon shipment provided that the selling price is fixed or determinable, persuasive evidence of an arrangement exists, collection of receivables is reasonably assured, and product returns are reasonably estimable.
When multiple elements are contained in a single arrangement, the Company allocates revenue between the elements based on their relative selling prices. The Company determines selling price using vendor specific objective evidence, or VSOE, if it is available, third-party evidence, or TPE, if VSOE is not available, and best estimate of selling price, or BESP, if neither VSOE nor TPE are available. The Company generally expects that it will not be able to establish TPE due to the nature of the markets in which it competes, and, as such, it will typically determine selling price using VSOE or if not available, BESP. The objective of BESP is to determine the selling price of a deliverable on a standalone basis. The Company’s determination of BESP involves a weighting of several factors based on the specific facts and circumstances of an arrangement. Specifically, the Company considers the cost to produce the deliverable, the anticipated margin on that deliverable, the selling price and profit margin for similar parts, its ongoing pricing strategy, the value of any enhancements that have been built into the deliverable, and the characteristics of the varying markets in which the deliverable is sold.
Revenue recognition involves judgments, including assessments of expected returns and expected customer relationship periods. The Company analyzes various factors, including a review of specific transactions, its historical returns, average customer relationship periods, customer usage, customer balances, and market and economic conditions. Changes in judgments or estimates on these factors could materially impact the timing and amount of revenues and costs recognized. Should market or economic conditions deteriorate, the Company’s actual return or bad debt experience could exceed its estimate.
Certain product sales are made with a 30-day right of return. Since the Company can reasonably estimate future returns, it recognizes revenues associated with product sales that contain a right of return upon shipment and at the same time it records a sales return reserve, which reduces revenue and accounts receivable by the amount of estimated returns. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Accounts Receivable | Accounts ReceivableTrade accounts receivable are recorded at the invoiced amount and do not bear interest. Accounts receivable on the balance sheet are recorded net of the allowance for doubtful accounts receivable and the reserve for estimated returns. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in its existing accounts receivable. The Company reviews its allowance for doubtful accounts and determines the allowance based on an analysis of customer past payment history, product usage activity, and recent communications between the Company and the customer. Past due balances are reviewed individually for collectibility. Account balances are written-off against the allowance when the Company feels it is probable the receivable will not be recovered. The Company does not have any off-balance sheet credit exposure related to its customers. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Income Taxes | Income TaxesThe Company records income taxes using the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax bases, and operating loss and tax credit carryforwards. The Company’s financial statements contain certain deferred tax assets, which have arisen primarily as a result of operating losses, as well as other temporary differences between financial and tax accounting. In accordance with the provisions of the Income Taxes topic of the Codification, the Company is required to establish a valuation allowance if the likelihood of realization of the deferred tax assets is reduced based on an evaluation of objective verifiable evidence. Significant management judgment is required in determining the Company’s provision for income taxes, the Company’s deferred tax assets and liabilities and any valuation allowance recorded against those net deferred tax assets. The Company evaluates the weight of all available evidence to determine whether it is more likely than not that some portion or all of the net deferred income tax assets will not be realized. Utilization of the NOL and research and development credit carryforwards may be subject to a substantial annual limitation due to ownership change limitations that have occurred previously or that could occur in the future, as provided by Section 382 of the Internal Revenue Code of 1986, as well as similar state provisions. Ownership changes may limit the amount of NOL and tax credit carryforwards that can be utilized to offset future taxable income and tax, respectively. In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain shareholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period. If the Company has experienced a change of control, utilization of its NOL or tax credits carryforwards would be subject to an annual limitation under Section 382. Any limitation may result in expiration of a portion of the NOL or research and development credit carryforwards before utilization. Subsequent ownership changes could further impact the limitation in future years. Further, until a study is completed and any limitation known, no amounts are being presented as an uncertain tax position. A full valuation allowance has been provided against the Company’s NOL carryforwards and research and development credit carryforwards and, if an adjustment is required, this adjustment would be offset by an adjustment to the valuation allowance. Thus, there would be no impact to the balance sheet or statement of operations if an adjustment were required. Management performed a two-step evaluation of all tax positions, ensuring that these tax return positions meet the “more likely than not” recognition threshold and can be measured with sufficient precision to determine the benefit recognized in the financial statements. These evaluations provide management with a comprehensive model for how a company should recognize, measure, present, and disclose in its financial statements certain tax positions that the Company has taken or expects to take on income tax returns. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Research and Development | Research and DevelopmentCosts incurred in the research and development of the Company’s products are expensed as incurred. Included in research and development costs are wages, benefits, product design consulting, and other operating costs such as facilities, supplies, and overhead directly related to the Company’s research and development efforts. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Product Warranty Costs | Product Warranty CostsThe Company accrues estimated product warranty costs at the time of sale which are included in cost of sales in the statements of operations. The amount of the accrued warranty liability is based on historical information such as past experience, product failure rates, number of units repaired, and estimated cost of material and labor. The liabilities for product warranty costs of $18,629 and $32,308 at December 31, 2012 and 2011, respectively, are included in accrued expenses in the accompanying balance sheets. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fixed Assets and Long-Lived Assets | Fixed Assets and Long-Lived AssetsFixed assets are recorded at cost and depreciated using the straight-line method over the estimated useful life of each asset. Expenditures for repairs and maintenance are charged to expense as incurred. On disposal, the related assets and accumulated depreciation are eliminated from the accounts and any resulting gain or loss is included in the Company’s statement of operations. Leasehold improvements are amortized over the shorter of the estimated useful life of the improvement or the remaining term of the lease. The Company periodically evaluates the recoverability of its fixed assets and other long-lived assets whenever events or changes in circumstances indicate that an event of impairment may have occurred. This periodic review may result in an adjustment of estimated depreciable lives or asset impairment. When indicators of impairment are present, the carrying values of the asset are evaluated in relation to the assets operating performance and future undiscounted cash flows of the underlying assets. If the future undiscounted cash flows are less than their book value, an impairment may exist. The impairment is measured as the difference between the book value and the fair value of the underlying asset. Fair values are based on estimates of the market prices and assumptions concerning the amount and timing of estimated future cash flows and assumed discount rates, reflecting varying degrees of perceived risk. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Accounting for Stock-Based Compensation | Accounting for Stock-Based CompensationStock-based compensation cost is generally recognized ratably over the requisite service period. The Company uses the Black-Scholes option pricing model for determining the fair value of its stock options and amortizes its stock-based compensation expense using the straight-line method. The Black-Scholes model requires certain assumptions that involve judgment. Such assumptions are the expected share price volatility, expected life of options, expected annual dividend yield, and risk-free interest rate (See Note 3 – Stock-Based Compensation and Equity). |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Net Loss per Common Share | Net Loss per Common Share
Basic net loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Unvested restricted shares, although legally issued and outstanding, are not considered outstanding for purposes of calculating basic net loss per share. Diluted net loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding during the period plus the dilutive effect of outstanding instruments such as options, warrants, and restricted stock. Because the Company has reported a net loss for all periods presented, diluted loss per common share is the same as basic loss per common share, as the effect of utilizing the fully diluted share count would have reduced the net loss per common share. Therefore, in calculating net loss per share amounts, the following shares underlying potentially dilutive common stock equivalents were excluded from the calculation of diluted net income per common share because their effect was anti-dilutive for each of the periods presented:
Warrants outstanding at December 31, 2012 were issued in the public offering completed on February 13, 2012 (see Note 14, Public Offering of Common Stock and Warrants, for further details). Warrants outstanding at December 31, 2011 and 2010 were redeemed in March 2012 in exchange for 23,127 shares of common stock. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Advertising and Promotional Costs | Advertising and Promotional CostsAdvertising and promotional costs are expensed as incurred. Advertising and promotion expense was $242,000, $426,000, and $256,000 in the years ended December 31, 2012, 2011, and 2010, respectively. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Accumulated Other Comprehensive Items | Accumulated Other Comprehensive ItemsFor the years ended December 31, 2012, 2011, and 2010, the Company had no components of other comprehensive income or loss other than net loss. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Segments | SegmentsThe Company operates in one segment for the sale of medical equipment and consumables. Substantially all of the Company’s assets, revenues, and expenses for the years ended December 31, 2012, 2011, and 2010 were located at or derived from operations in the United States. Revenues from sales outside the United States accounted for approximately 7% of total revenues in 2012, 6% of total revenues in 2011, and 2% of total revenues in 2010. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Risks and Uncertainties | Risks and UncertaintiesThe Company is subject to risks common to companies in the medical device industry, including, but not limited to, development by the Company or its competitors of new technological innovations, dependence on key personnel, customers’ reimbursement from third-party payers, protection of proprietary technology, and compliance with regulations of the FDA and other governmental agencies. In late 2011, the Company launched NC-stat DPNCheck, which is a fast, accurate, and quantitative nerve conduction test for the assessment of systemic neuropathies such as DPN. In early 2013 the Company launched SENSUS for the treatment intractable pain, including pain associated with diabetic neuropathy. The future prospects of the Company are closely tied to its success with NC-stat DPNCheck and SENSUS in market acceptance and growth in future revenues. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Recently Issued or Adopted Accounting Pronouncements | Recently Issued or Adopted Accounting PronouncementsIn May 2011, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2011-04, “Fair Value Measurement (Topic 820) — Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS”, or ASU 2011-04. The amendments in ASU 2011-04 result in common fair value measurement and disclosure requirements in GAAP and International Financial Reporting Standards, or IFRS. Consequently, the amendments change the wording used to describe many of the requirements in GAAP for measuring fair value and for disclosing information about fair value measurements. The Company adopted this new guidance prospectively beginning January 1, 2012. Adoption has not had a material effect on the Company’s financial statements. In June 2011, the FASB issued ASU No. 2011-05, “Comprehensive Income (Topic 220) — Presentation of Comprehensive Income”, or ASU No. 2011-05. ASU No. 2011-05 requires that all nonowner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements, eliminating the option to present other comprehensive income in the statement of changes in equity. Under either choice, items that are reclassified from other comprehensive income to net income are required to be presented on the face of the financial statements where the components of net income and the components of other comprehensive income are presented. In December 2011, the FASB issued ASU No. 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05”, which defers the requirement within ASU No. 2011-05 to present on the face of the financial statements the effects of reclassifications out of accumulated other comprehensive income on the components of net income and other comprehensive income for all periods presented. During the deferral, entities should continue to report reclassifications out of accumulated other comprehensive income consistent with the presentation requirements in effect prior to the issuance of ASU No. 2011-05. The Company adopted this new guidance retrospectively beginning January 1, 2012. Adoption has not had a material effect on the Company’s financial statements. |

|
- Definition
This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Company may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Reference 1: http://www.xbrl.org/2003/role/presentationRef
