Testing a Non-Invasive Spinal Stimulation Device

Participants will lay on their back and have small electrodes placed on the center of their backs and several leg muscles. The back electrodes, connected to a battery-operated unit, will send an electrical current to the spine. The leg electrodes will record muscle activity. This will take approximately 2 hours to complete on each day. The 2 hours includes set-up/placement of the electrodes, 4 trials of stimulation with breaks, and removal of electrodes after testing.
