Ladies/Gentlemen:

    At your request, we have examined the Registration Statement on Form SB-2
(the "Registration Statement") to which this letter is attached as Exhibit 5.1
filed by Myo Diagnostics, Inc., a California corporation (the "Company"), in
order to register under the Securities Act of 1933, as amended (the "Act"),
2,730,006 shares of Common Stock, no par value, of the Company (the "Outstanding
Shares"), and 525,555 shares of Common Stock, no par value of the Company
underlying certain warrants (the "Underlying Shares").

    We are of the opinion that the Outstanding Shares have been duly authorized
and are validly issued, fully paid and non-assessable.

    We are of the opinion that the Underlying Shares have been duly authorized
and, upon exercise and payment of the exercise price therefor in accordance with
the terms of the warrants, will be validly issued, fully paid and
non-assessable.

    We consent to the use of this opinion as an Exhibit to the Registration
Statement and to use of our name in the Prospectus constituting a part thereof.


                        Respectfully submitted,
