ABSTRACT:
An apparatus for stimulating and controlling the contraction of muscles includes conductive electrodes for contacting spaced-apart locations on the body between which are the muscles to be exercised. The electrodes are connected to a signal supply circuit which includes a pulse generator, a modulator circuit, a push-pull amplifier, a current control circuit and a transformer, the primary winding of which is driven by the amplifier and the secondary winding of which is connected to the electrodes. A second, lower repetition rate, pulse generator can be included to modulate the output so that signals are provided in spaced groups of pulses. The controlled current output is adjustable and monitored by a meter. A counter for counting pulse groups is included.
