Photograph showing the used method in the study. The course of the superficial peroneal nerve, or if divided its terminal branches, was determined by creating a window (20 mm wide and 15 mm long), only affecting the skin without manipulating the nerve. Manipulating the ankle in the different ankle positions was standardized by means of the Telos stress device (Telos equipment, Weiterstadt, Germany). The reference point was regarded being the combined plantar flexion and inversion position. In this position, the medial edge of the nerve was marked with a pin (yellow in the photography)
