Effect of quality of forelimb movements in a decerebrate cat on stepping performance of the hindlimbs during ES in the presence of K. EMG recordings in the LBB, LTB, LVL, and RLG during ES-induced stepping in the presence of K plus air stepping (A) or weight-bearing stepping on a treadmill (B). The mean cycle period, mean EMG burst duration, and mean integrated area of the rectified EMG burst of the LVL and RLG during air stepping or weight-bearing stepping induced by ES and in presence of K are shown in C. Note the more robust EMG bursts in both the forelimb and hindlimb muscles during weight-bearing than during air stepping. Significantly different at *p < 0.05. Abbreviations, same as in Figures 1 and 2.
