Abstract
A portable single or two channel, electrically energized device for applying a series of therapeutic pulse type electrical stimulations to a human body member including individual channel controls for pulse frequency, pulse width and pulse amplitude and circuitry therefore.
Claims4
Two channel means for applying electrical impulses to a body through electrodes comprising:
- a. a first circuit including a first electrode and a common electrode;
- b. a second circuit including a second electrode and said common electrode;
- and manual means in each circuit for independently controlling the frequency of pulses delivered to the first and second electrodes.
The method of controlling human pain and discomfort including but not limited to that arising from withdrawal of a habituated chemical or activity comprising the steps of:
- a. applying high voltage pulses to a body member between a first location and a common location at a first frequency and simultaneously
- b. applying high voltage pulses to the body member between a second location and said common location at a second frequency.
