Abstract
Abstract Temporomandibular joint-myofascial pain dysfunction syndrome (TMJ-MPDS) treatment apparatus and methodology employs a transcutaneous electronic wave to suppress pain associated with TMJ-MPDS. A first positive contact electrode is placed at the pain site and a second positive contact electrode is placed at the contra-lateral temporomandibular joint; and a negative contact electrode is placed at the web of the ipsilateral hand. An electronic current wave comprising relatively high frequency pulses with a low frequency amplitude modulation is then applied between the first to the second electrodes.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
69 words
A method for suppressing pain associated with the disease temporomandibular including the steps of securing a first positive electrode on the pain site, a second positive electrode on the contra-lateral temporomandibular joint, and securing a negative electrode connected electrically in common to the web of the subject's ipsilateral hand, and supplying an electrical wave comprising a high frequency amplitude modulation to said first, and said second and third electrodes.
Claim 2
Independent Claim
69 words
A method for suppressing pain associated with the disease temporomandibular including the steps of securing a first positive electrode on the pain site, a second positive electrode on the contra-lateral temporomandibular joint, and securing a negative electrode connected electrically in common to the web of the subject's ipsilateral hand, and supplying an electrical wave comprising a high frequency amplitude modulation to said first, and said second and third electrodes.
Claim 3
Dependent Claim
43 words
The method as in claim 1, wherein the frequency of said high frequency electrical wave was in the range of 12-20 khz, wherein said low frequency modulation is in the range 8-20 hz, and wherein said wave does not exceed about 4 milliamperes.
Claim 4
Dependent Claim
14 words
The method as in claim 1 or 2, wherein said amplitude modulation is non-symmetrical.
