Example frontal plane kinematics and hip abductor EMG activity from a representative participant with iSCI. Frontal plane kinematics (left) and hip abductor EMG data (right) for a representative participant with iSCI during the first 9 steps of the second unassisted walking period of each trial. The group time constant of 9 steps represents the average number of steps across all participants with iSCI to return to steady state during Transition 1 and was used to calculate metrics for all trials for consistency. COM variability visibly decreased over repetitions of the transition, showing savings. Muscular activity showed a slight trend of decrease over repetitions of the transition
