Abstract
Abstract Cerebral palsy treatment apparatus and methodology employs a transcutaneous electronic wave to suppress pain and increase motor function. A first positive contact electrode is placed at the frontalis, and a second negative contact electrode is placed at the occiput of the head. Alternatively, the first positive contact electrode is placed at the cervical spinous process and the second negative contact electrode is placed at each affected muscle. 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: 8
Claim 1
Independent Claim
62 words
A method for suppressing pain and reducing spasticity and other symptoms associated with cerebral palsy including the steps of securing a first electrode at the frontalis muscle, securing a second electrode connected electronically in common to the occiput of the subject's head, and supplying an electrical wave comprising a high frequency amplitude modulation to said first, and said second and third electrodes.
Claim 2
Independent Claim
62 words
A method for suppressing pain and reducing spasticity and other symptoms associated with cerebral palsy including the steps of securing a first electrode at the frontalis muscle, securing a second electrode connected electronically in common to the occiput of the subject's head, and supplying an electrical wave comprising a high frequency amplitude modulation to said first, and said second and third electrodes.
Claim 3
Independent Claim
55 words
A method for suppressing pain and reducing spasticity and other symptoms associated with cerebral palsy including the steps of securing first electrode means at the cervical spinous process, securing second electrode means to each affected muscle, and supplying an electrical wave comprising a high frequency amplitude modulation to said first and said second electrode means.
Claim 4
Independent Claim
55 words
A method for suppressing pain and reducing spasticity and other symptoms associated with cerebral palsy including the steps of securing first electrode means at the cervical spinous process, securing second electrode means to each affected muscle, and supplying an electrical wave comprising a high frequency amplitude modulation to said first and said second electrode means.
Claim 5
Dependent Claim
45 words
