<p>A method and apparatus (10) are provided for electrically stimulating muscle (52) of individuals having little or no nerve damage so the muscle can be power contracted with little pain to the individual. A therapeutic current (36) is applied to the muscle (52) which includes alternating desensitizing (56) and stimulus (60) currents. The desensitizing current (56) is a high frequency, low amplitude current to desensitize the muscle and the stimulus current (60) is a low frequency, high amplitude current to stimulate the muscle. The currents alternate at a point (62) where the amplitude and slope of the two currents are substantially identical to avoid abruptions in the current. An onset failure monitor circuit (21) is also provided to detect an increase in skin/electrode impedance (236) indicative of possible subsequent failure of the ski-electrode connection or electrode failure.</p> |
