Figure 4From: Peak hip and knee joint moments during a sit-to-stand movement are invariant to the change of seat height within the range of low to normal seat height 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%.Back to article page
