Percutaneous High Frequency Alternating Current Stimulation in Healthy Volunteers With 30kHz

"A charge-balanced, symmetric, biphasic sinusoidal current without modulation will be delivered at a frequency of 30 kHz. The stimulation intensity will be defined as that sufficient to produce a strong but comfortable sensation, just below motor threshold, over the median nerve through the electrotherapy device Myomed 932. (Enraf-Nonius, Delft,Netherlands)"

Sham stimulation will be delivered at a frequency of 30 kHz only during the first 30 seconds.
