Ladies and Gentlemen:

We have acted as counsel to NanoVibronix, Inc., a Delaware corporation (the “Company”), in connection with the preparation of the Company’s registration statement on Form S-1 (Registration No. 333-284973) and the preliminary prospectus forming a part of the registration statement (the “Prospectus”), under the Securities Act of 1933, as amended (the “Securities Act”), initially filed by the Company with the Securities and Exchange Commission (the “Commission”) on February 14, 2025, as thereafter amended or supplemented (the “Registration Statement”). The Prospectus relates to the registration of the proposed offering of an aggregate of (i) 460,000 shares of Series G Convertible Preferred Stock (the “Preferred Stock”), par value $0.001 per share and with an assumed stated value of $25 per share (the “Preferred Shares”), convertible into 1,782,947 shares of common stock (the “Conversion Shares”) of the Company, par value $0.001 per share (the “Common Stock”), (ii) 802,327 shares of Common Stock issuable as cumulative dividend at the rate per share of 9% per annum of the assumed stated value per share of $25, until the fifth anniversary of the date of issuance of the Preferred Stock (the “Dividend Shares”), (iii) warrants (the “Warrants”) to purchase 1,782,947 shares of Common Stock (the “Warrant Shares”), and (iv) representative’s warrants (the “Representative’s Warrants”) to purchase 89,148 shares of Common Stock (the “ Representative’s Warrant Shares”). The Preferred Shares, the Conversion Shares, the Dividend Shares, the Warrants, the Warrant Shares, the Representative’s Warrants and the Representative’s Warrant Shares are collectively referred to as the “Securities.”

In rendering the opinion set forth herein, we have examined the originals, or photostatic or certified copies, of (i) the Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws of the Company, each as amended and/or restated as of the date hereof (together, the “Company Charter Documents”), (ii) certain resolutions of the Board of Directors of the Company (the “Board”) related to the filing of the Registration Statement, the authorization and issuance of the Securities and related matters, (iii) the Registration Statement and all exhibits thereto, (iv) the form of underwriting agreement to be entered into by and among the Company and the Representative (the “Underwriting Agreement”), (v) the form of Warrant, (vi) the form of Representative’s Warrant, (vii) the engagement letter, dated as of February 11, 2025, by and between the Company and Dawson James Securities, Inc. (the “Engagement Letter”), (viii) the form of Certificate of Designations of the Series G Convertible Preferred Stock (the “Certificate of Designations”) to be filed prior to issuance of the Preferred Shares with the Secretary of State of the State of Delaware, (ix) a certificate executed by an officer of the Company, dated as of the date hereof, and (x) such other records, documents and instruments as we deemed relevant and necessary for purposes of the opinion stated herein.

We have relied upon such certificates of officers of the Company and of public officials and statements and information furnished by officers of the Company with respect to the accuracy of material factual matters contained therein which were not independently established by us. In such examination we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as photostatic or certified copies, and the authenticity of the originals of such copies.
