关节在功能活动中产生的内部力矩是肌肉收缩和关节及其周围软组织粘弹性特性的结果。评估了在人类水平行走期间，这些机制中的每一个对踝关节产生的总内部力矩的收缩。在正常水平行走时，踝关节周围的内部力矩主要是由关节周围肌肉的收缩引起的。发现无源分量的贡献可以忽略不计。这些结果，然而，被发现是不同的病理病例测试。在患有轻度马蹄形踝关节畸形的患者中，大部分（21%）的内力矩是由关节及其周围结构的被动阻力造成的。
The internal moment developed about a joint during a functional activity is the result of contraction of muscles and the visco-elastic properties of the joint and its surrounding soft tissues. The contraction of each one of these mechanisms to the total internal moment developed about the ankle joint during human level walking was assessed. During normal level walking the internal moment about the ankle is mainly due to contraction of muscles surrounding the joint. The contribution of the passive component was found to be negligible. These results, however, were found to be different for the pathological case tested. In a subject with a mild equinus ankle deformity, a substantial (21%) of the total internal moment was contributed by the passive resistance of the joint and its surrounding structures.
