Fig. 6From: Patterns of whole-body muscle activations following vertical perturbations during standing and walkingElectromyography (EMG) activity driven by visual perturbations. Filtered and rectified EMG activity of left tibialis anterior following an upward visual perturbation while standing. The figure shows a time window from one second before to two seconds after visual perturbation. Onset latency was 1.2 s, duration of activation was 723 ms, and magnitude of activation was 3.85 μV*sBack to article page
