Comparative Study of Two Ultrasound-guided Percutaneous Neuromodulation Protocols on Maximal Handgrip Strength.

a protocol of percutaneous neuromodulation of the median nerve consisting of 5 cycles of 5 seconds stimulation (100 Hz and 350 µs pulse width), followed by 55 seconds rest.

a protocol of percutaneous neuromodulation of the median nerve consisting of 10 cycles of 10 seconds stimulation (10 Hz and 250 µs pulse width), followed by 10 seconds rest.
