Example frontal plane kinematics and hip abductor EMG activity from a representative non-impaired participant. Frontal plane kinematics (left) and hip abductor EMG data (right) for a representative non-impaired participant during the first 22 steps of the second unassisted walking period of each trial. The group time constant of 22 steps represents the average number of steps across all non-impaired participants to return to steady state during Transition 1 and was used to calculate metrics for all trials for consistency. Muscular activity decreased over repetitions of the transition, showing slacking
