Abstract
Abstract An apparatus and a method for generating a train of up-and down-and up-staircase shaped electrical pulses whose peak negative amplitude is two-thirds of its peak positive amplitude and whose frequency can be varied between one hertz and one thousand hertz and applying these electrical pulses to the body for the treatment of nerve function and impairment and pain.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
78 words
A method of treating nerve impairment which comprises the steps of: a. producing a series of up-and down-and up-staircase-shaped electrical pulses, each of said pulses having a preset period T, each of said pulses having a peak positive amplitude V in the first half of said period T, and a peak negative amplitude of two-thirds of V in the second half of said period T; and b. applying said series of pulses to a part of the body.
Claim 2
Independent Claim
78 words
A method of treating nerve impairment which comprises the steps of: a. producing a series of up-and down-and up-staircase-shaped electrical pulses, each of said pulses having a preset period T, each of said pulses having a peak positive amplitude V in the first half of said period T, and a peak negative amplitude of two-thirds of V in the second half of said period T; and b. applying said series of pulses to a part of the body.
Claim 3
Dependent Claim
172 words
The method of treating nerve impairment as in claim 1, wherein each of said pulses has a zero amplitude for the first tenth of said period T, a positive amplitude equal to one half of said peak positive amplitude V during the second tenth of said period T, a positive amplitude equal to said peak positive amplitude V during the third tenth of said period T, a positive amplitude equal to one half of said peak positive amplitude V during the fourth tenth of said period T, a zero amplitude during the fifth and sixth tenths of said period T, a negative amplitude equal to one-third of said peak positive amplitude V during the seventh tenth of said period T, a negative amplitude equal to two-thirds of said peak positive amplitude V during the eighth tenth of said period T, a negative amplitude equal to one-third of said peak positive amplitude V during the ninth tenth of said period T, and a zero amplitude during the tenth tenth of said period T.
