Abstract
Abstract A method and apparatus for obtaining neurophysiological effects on the central and/or peripheral systems of a patient. Electrodes are suitably positioned on the body of the patient and a composite electric signal is applied at the electrodes. The composite signal is formed by the superpositioning of two signals: a first signal which is a rectified high-frequency carrier modulated in amplitude to about 100 percent by substantially square-shaped pulses whose duration, amplitude and frequency are chosen according to the neurophysiological effects desidered, and a second signal which has a relatively white noise spectrum. The mean value of the first electric signal has a predetermined sign which is opposite the sign of the mean value of the second electric signal.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
153 words
A method for obtaining neurophysiological effects on the central and/or peripheral nervous systems of a patient, comprising generating a high-frequency carrier, rectifying the high-frequency carrier, generating substantially square-shaped pulses whose duration, amplitude and frequency are chosen according to the desired neurophysiological effect, amplitude modulating to about 100 percent the rectified high-frequency carrier with said pulses thereby producing a first electric signal, generating a relatively white noise spectrum signal, rectifying the relatively white noise spectrum signal thereby producing a second electric signal, the sign of the mean value of the second electric signal being opposite that of the mean value of said first electric signal, superposing said first and second electric signals to produce a composite electric signal having an average amplitude which is the difference between the average amplitude of said first and second electric signals, positioning electrodes on the body of the patient, and applying said composite electric signal at the electrodes.
Claim 2
Independent Claim
153 words
A method for obtaining neurophysiological effects on the central and/or peripheral nervous systems of a patient, comprising generating a high-frequency carrier, rectifying the high-frequency carrier, generating substantially square-shaped pulses whose duration, amplitude and frequency are chosen according to the desired neurophysiological effect, amplitude modulating to about 100 percent the rectified high-frequency carrier with said pulses thereby producing a first electric signal, generating a relatively white noise spectrum signal, rectifying the relatively white noise spectrum signal thereby producing a second electric signal, the sign of the mean value of the second electric signal being opposite that of the mean value of said first electric signal, superposing said first and second electric signals to produce a composite electric signal having an average amplitude which is the difference between the average amplitude of said first and second electric signals, positioning electrodes on the body of the patient, and applying said composite electric signal at the electrodes.
Claim 3
Dependent Claim
23 words
A method according to claim 1, wherein said first and second signals each have polarities which are constant as a function of time.
Claim 4
Dependent Claim
22 words
A method according to claim 1, wherein the spectrum of the said relatively white noise is between 1 KHz and 60 KHz.
Claim 5
Dependent Claim
20 words
A method according to claim 3, wherein the spectrum of said relatively white noise is between 20 and 60 KHz.
Claim 6
Dependent Claim
32 words
A method according to claim 1, wherein the ratio between the mean current strength of said second signal and the mean current strength of said first signal is between one-fourth and one-half.
