Abstract
An electronic neuromuscular stimulation device (10) that is operated by a computerized electronic control unit (20). The unit (20) includes at least two and preferably four output channels to which are connected a corresponding set of electrode output cables (12). Each cable has attached a positive electrode (12D) and a negative electrode (12E) that are attached to selected areas of a patient'"'"'s anatomy. The unit (20) also includes controls, indicators, and circuitry that produce nerve stimulation pulses that are applied to the patient through the electrodes (12D,12E). The nerve stimulation pulses consist of individual pulses that are arranged into pulse trains and pulse train patterns. The pulse train patterns, whose selection depends on the type of ailment being treated, includes sequential patterns, delayed overlapping patterns, triple-phase overlapping patterns, reciprocal pulse trains, and delayed sequenced "sprint interval" patterns. The overlapping patterns are particularly timed to take advantage of neurological enhancement.
