Transcutaneous electrical nerve stimulation (Empi, USA)
In the active TENS group, TENS at 80 pulsed currents per second (PPS) with a pulse duration of 200 μs were delivered for 20 minutes. Current amplitude was slowly increased until a level was reached that participants reported was the maximum level they could tolerate below pain threshold without noticeable muscle contraction and maintained this intensity.

"In the placebo group the TENS device had no current output although the power on indicator light remained active."
