Figure 4From: Tibialis posterior in health and disease: a review of structure and function with specific reference to electromyographic studies Tibialis posterior EMG activity during walking in health and disease. Tibialis posterior EMG activity during walking in health and disease – schematic estimates for ensemble-averaged tracings adapted from the respective studies. 0% and 100% represents heel contact to ipsilateral heel contact. Vertical lines show average timing of temporal gait events. Time resolution is approximated from original work to show a single gait cycle during walking. Amplitude characteristic are not scaled and cannot be compared among different studies. Linear envelopes for figure D-G show estimated unfiltered/unrectified signals. NB. Where multiple studies are available for each category, representation was based on the most recent work with the largest sample size.Back to article page
