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. |
