Figure 3

Angular excursions of the right knee joint and corresponding rectified EMG activity in the left and in the right hamstrings when stimulating at T11,30 Hz (A,C) and when combining with imagining stepping (B,D) in subjects TM (A,B) and VS (D,E). (C) Mean peak-to-peak excursion amplitudes (% of tSCS alone) at the knee joint and the corresponding cycle period durations (F) are shown for the 8–10 step-like movements in a gravity-neutral apparatus in response to stimulation at T11 only and at VIS+tSCS for three subjects: vs, sh, and tm (subject vs and sh were tested twice). *Significantly different at p < 0.05.
