Ensemble average of the joint moment during STS movements from the seat heights of six different heights: (a) hip, (b) knee and (c) ankle joint moments. Time = 0 and 100 (%) respectively indicates the instance of seat-off and finish time. The grey area indicates ± 1 standard deviation of the ensemble average. The hip and knee joint moments reached a peak near the time of 0%. On the other hand, the ankle joint moment reached a peak near the time of 100%.
