A muscle stimulator provides an electrical output pulse train which provides functional electrical stimulation (FES) of muscles or muscle groups. The muscle stimulator includes a manually operated amplitude control which provides an amplitude control signal for controlling the amplitude of the output pulse train. During a PROGRAM mode, a clinician manipulates the amplitude control to establish a desired FES regimen. An analog-to-digital converter periodically samples the amplitude control signal during the PROGRAM mode, and data from the analog-to-digital converter is stored. When an EXECUTE mode is selected, the pulse width of the output pulse train is automatically controlled as a function of the stored data to reproduce the desired FES regimen which had been established during the PROGRAM mode.
