Figure 3From: 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 mechanical load during STS movements from the seat heights of six different heights. 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 mechanical load reached a peak near the time of 0%.Back to article page
