Abstract
An improved muscle stimulator, particularly suited to long term rhythmic stimulation for the selective development of musculature otherwise asymmetric or retarded in relative development. To minimize the subjects' awareness of stimulation, to permit nocturnal use, and to minimize battery consumption, the energy content of each pulse train is modulated by a progressive increase of pulse width up to a maximum, followed by a progressive decrease of pulse width, thus yielding a gradual contraction and relaxation of the muscle.
