Measure
Narrow Pulse
Six-week treatment of electrical stimulation applied to the calf muscles with stimulus pulses that last 0.4 ms. Narrow pulse: Participants will be randomly assigned to one of two study arms to receive a 6 week treatment of electrical stimulation that comprises narrow (0.4 ms) stimulus pulses.
Wide Pulse
Six-week treatment of electrical stimulation applied to the calf muscles with stimulus pulses that last 1 ms. Wide pulse: Participants will be randomly assigned to one of two study arms to receive a 6 week treatment of electrical stimulation that comprises wide (1 ms) stimulus pulses.
