Force analysis during CR. The abduction force, Fw, was applied on the point of knee, with the force direction being vertical to the axis of the thigh. The fixed constraint was applied to the surrounding of the femur and to the rotation of thigh axis to simulate the restriction of surrounding tissues. The value of the force for each muscle can be solved according to the table of force ratio of each muscle when the muscle forces and external applied loads staying in the idle state for the thigh
