The elastic component of the passive moment at the knee was measured in situ. The force needed to manually range the knee from approximately 90 degrees of flexion to full extension was measured. Hip and ankle angle were held fixed. The passive knee moment, computed from the force and knee angle data, was compared to the total knee moment required for normal gait. This comparison suggested that the passive moment can contribute a significant portion of the total joint moment during some phases of the gait cycle.
在原位测量了膝关节被动力矩的弹性成分。测量了将膝关节从大约90度屈曲手动伸展至完全伸直所需的力。髋关节和踝关节角度保持固定。根据力和膝关节角度数据计算出的被动膝关节力矩与正常步态所需的总膝关节力矩进行了比较。这种比较表明，在步态周期的某些阶段，被动力矩可占总关节力矩的很大一部分。
