The purpose of this study is to determine the effects of transcutaneous electrical nerve stimulation (TENS) on pain and mobility by comparing different stimulation sitesP: 1. the location with the lowest resistance 2. the location that causes an irradiation sensation 3. a random stimulation site (but within a 10x10cm area of the irradiation site). The effect is defined as the pain VAS baseline-measurement before treatment minus the pain VAS repeat-measurement after the given treatment
