Abstract

A method for effecting percutaneous pain alleviation in which right-angled sawtooth shaped electrical pulses are produced at electrodes for percutaneous application to bodily areas experiencing pain. One of the electrodes is located at the site of the pain while the other electrode is moved to different sites of the region of the pain. At the same time the amplitude of the electrical signals is measured for each site until a maximum amplitude site is located. Thereafter, an electrode is continuously positioned at the located site for a given period of time for continuous application of the electrical pulses which may be selectively varied in amplitude in the range of zero to about 100 volts peak-to-peak and the output current controlled from 1 MA to 40 MA, while the pulse repetition frequency may be selectively varied in the range of about 10 HZ to 100 HZ.

Claims

1. The method of alleviating pain at a portion of the body of a user comprising the steps of generating periodically recurring electrical pulse signals, applying said pulse signals to a base electrode and at least one other electrode, positioning the base electrode at the site of the body experiencing the pain, scanningly applying one of said other electrodes to various portions of the body, at each point of application measuring the amplitude of the electrical pulse signals fed between said base electrode and said one of said other electrodes, indicating the point of application yielding the maximum amplitude of the electrical pulse signals, thereafter positioning at least one of said other electrodes at the indicated point of application for a given period of time while said base electrode remains positioned at the site of the body experiencing the pain, whereby the electrical pulse signals block the pain at that site of the body.

2. The method of claim 1, after said electrodes are positioned at the site of the body experiencing pain and at the indicated point of application, varying the amplitude of the electrical pulse signals to achieve the desired blocking.

3. The method of claims 1 or 2 wherein the electric pulse signals has a right-angled sawtooth waveform.

4. The method of claim 1 wherein the scanningly applying step applies said one electrode such that the pain site, said one electrode and the head of the user are in a line.

5. The method of claims 1 or 4 wherein the scanning applying step applies said one electrode at a point between the pain site and the head of the user.
