Sagittal plane kinematics for the hip, knee, and ankle on the more-affected limb during walking with sensorimotor (SM), audiovisual (AV) and combined (AV + SM) biofeedback. The middle panels show median trends for baseline and all biofeedback modalities during the late phase (strides 181–210) of the pre-acclimation visit. Baseline trends show median (IQR). Bar plots depict median (IQR) changes from baseline for key points within the gait cycle. Initial contact is defined as the mean value over the first 5% of the gait cycle. Median values for post-acclimation (square) and follow-up (diamonds) visits are also presented. Note that because there was interparticipant variability in the timing of maximum angles, there is some discrepancy between the bar plots and median kinematic trends. *denotes significant differences from zero, indicating a change from baseline values (α = 0.05; Wilcoxon signed-rank tests with Holm-Šídák correction)
