Organization, Consolidation and Presentation of Financial Statements [Abstract]  
1. Organization
Description of Business
On January 15, 2014, a wholly-owned subsidiary of Ekso Bionics Holdings, Inc. named Ekso Acquisition Corp. merged with and into Ekso Bionics, Inc. (the “Merger”). Ekso Bionics, Inc. was the surviving corporation and became a wholly-owned subsidiary of Ekso Bionics Holdings, Inc. As a result of this transaction, Ekso Bionics Holdings, Inc. discontinued its pre-merger operations, acquired the business of Ekso Bionics, Inc. and continues the operations of Ekso Bionics, Inc. as a publicly traded company. See Note 3, 2014 Merger, Offering and Other Related Transactions. Ekso Bionics, Inc. was incorporated in January 2005 in the State of Delaware. 
As used in these notes to the consolidated financial statements, the term “the Company” refers to Ekso Bionics Holdings, Inc. formerly known as PN Med Group, Inc., and its wholly-owned subsidiaries, including Ekso Bionics, Inc. after giving effect to the Merger; the term “Holdings” refers to the business of Ekso Bionics Holdings, Inc. prior to the Merger, and the term “Ekso Bionics” refers to Ekso Bionics, Inc. prior to the Merger. Unless otherwise indicated, all dollar and share amounts included in these notes to the consolidated financial statements are in thousands.
The Company designs, develops, and sells exoskeletons that augment human strength, endurance and mobility. The Company’s exoskeletons have applications in health care, industrial, military, and consumer markets.
Liquidity and Going Concern
Largely as a result of significant research and development activities related to the development of the Company’s advanced technology and commercialization of this technology into its medical device business, the Company has incurred significant operating losses and negative cash flows from operations since inception. The Company has also recognized significant non-cash losses associated with the revaluation of certain securities, which have also contributed significantly to its accumulated deficit. As of December 31, 2016, the Company had an accumulated deficit of $114,861.
Cash on hand at December 31, 2016 was $16,846, compared to $19,552 at December 31, 2015. For the year ended December 31, 2016, the Company used $24,972 of cash in operations compared to $18,269 for the year ended December 31, 2015. As noted in Note 9, Long-Term Debt, borrowings under our long-term debt agreement have a requirement of minimum cash on hand roughly equivalent to three months of cash burn. As of January 31, 2017, the most recent determination of this restriction, $6,026 of cash must remain as unrestricted, with such amounts to be re-computed at each month end period. After considering cash such restriction, effective unrestricted cash as of December 31, 2016 is estimated to be $10,820. Based on current forecasted amounts, our on hand will not be sufficient to satisfy our operations for the next twelve months from the date of issuance of  these consolidated financial statements, which raises substantial doubt about our ability to continue as a going concern.
Based upon the Company’s current cash resources, the recent rate of using cash for operations and investment, and assuming modest increases in current revenue offset by incremental increases in expenses related to increased sales and marketing and research and development, and a potential increase in rental activity from its medical device business, the Company believes it has sufficient resources to meet its financial obligations into the third quarter of 2017. The Company will require significant additional financing. The Company is actively pursuing opportunities to obtain additional financing in the future through public or private equity and/or debt financings, corporate collaborations, or warrant solicitations.  
The Company’s actual capital requirements may vary significantly and will depend on many factors. For example, the Company plans to continue to increase its investments (i) in its clinical, sales and marketing initiatives to accelerate adoption of the Ekso robotic exoskeleton in the rehabilitation market, (ii) in its research, development and commercialization activities with respect to an Ekso robotic exoskeleton for home use, and/or (iii) in the development and commercialization of able-bodied exoskeletons for industrial use. Consequently, the Company will require significant additional financing in the future, which the Company intends to raise through corporate collaborations, public or private equity offerings, debt financings, or warrant solicitations. Sales of additional equity securities by us could result in the dilution of the interests of existing stockholders. There can be no assurance that financing will be available when required in sufficient amounts, on acceptable terms or at all. In the event that the necessary additional financing is not obtained, the Company may be required to reduce its discretionary overhead costs substantially, including research and development, general and administrative, and sales and marketing expenses or otherwise curtail operations.
