Fig. 5

Typical torso lean and twist over the gait cycle for one subject (a-c). Solid and dotted lines represent the mean curve and standard deviation (±1 SD), respectively. In these plots, significant differences between conditions are indicated by a black bar at the top of the plot. Maximum upper body rotations about the pelvis during affected leg stance by subject for walking at 1 m/s (d) and 1.25 m/s (e). Positive sagittal and coronal rotations refer to lean forward and toward the affected side respectively. Transverse plane rotation of the torso about the pelvis rotating toward the stance leg. Significant (p ≤ 0.05) reductions (improved performance) in lean and twist are denoted by a star. Significant increases (worse performance) are noted by a circled star
