Median Nerve Stimulation Pilot

Square-wave 200 µs pulses triggered by computer at 12 Hz, at the threshold for thumb movement (expected \~2-15mA), applied to surface electrodes over the median nerve at the right wrist (conductive gel, 30 mm apart center-to-center, anode distal). This is a non-significant risk device study.

Square-wave 200 µs pulses triggered by computer at random intervals with a mean rate of 12 Hz (as described in Morera Maiquez et al., 2020), at the threshold for thumb movement (expected \~2-15mA), applied to surface electrodes over the median nerve at the right wrist (conductive gel, 30 mm apart center-to-center, anode distal). This is a non-significant risk device study.
