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 right side of the cranium, and a second negative contact electrode is placed at the left side of the cranium of the head. 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: 5
Claim 1
Independent Claim
67 words
A method for suppressing pain and reducing spasticity associated with cerebral palsy including the steps of respectively securing electrodes transcranially to the right and left side of a patient's head, a first electrode being secured to the right side and a second electrode to the left side, and applying a high frequency electrical wave bearing a low frequency amplitude modulation to said first and said second electrodes.
Claim 2
Independent Claim
67 words
A method for suppressing pain and reducing spasticity associated with cerebral palsy including the steps of respectively securing electrodes transcranially to the right and left side of a patient's head, a first electrode being secured to the right side and a second electrode to the left side, and applying a high frequency electrical wave bearing a low frequency amplitude modulation to said first and said second electrodes.
Claim 3
Dependent Claim
29 words
The method of claim 1, in which said first and second electrodes are respectively placed between the ear and temple on left and right sides of the patient's head.
Claim 4
Dependent Claim
42 words
The method as in claim 1, wherein the frequency of said high frequency electrical wave is in the range of 12-20 khz, wherein said low frequency modulation is in the range 8-20 hz, and wherein said wave is less than 4 milliamperes.
Claim 5
Dependent Claim
12 words
