1. A transcutaneous electrical nerve stimulator for pain control comprising:
- oscillator means for generating a stimulation control pulse signal having predetermined rate, pulse width, and pulse amplitude factors;
output means for producing nerve stimulating pulse signals having parameters as respective functions of said factors;
said output means comprising means for independently establishing and independently controlling the pulse rise time and pulse decay time of select pulses of said stimulating signal selectively to establish a stimulating signal waveshape to which given nerves are selectively responsive, thereby producing effective pain control with respect to said given nerves.

Abstract
In a transcutaneous nerve stimulating apparatus, the stimulating pulse wave form is shaped and manipulated to accommodate specific physiological parameters, and to allow multiple non-interfering electrode administrations. The stimulating pulse wave form, of desired pulse rate, pulse duration, and pulse amplitude, optionally includes successive pulses of alternating plurality, which may all be coupled to a single electrode, alternately coupled to plural electrodes, or the like. Pulse decay is controlled, as is pulse rise time. Voltage regulation is provided to the pulse generation apparatus.
