habili ed for ynam ound during toe and heel-toe walking performed by able-bodied subjects to identify possible compensatory mechanisms necessary to toe walk. The simulations showed that an increased magnitude of plantar flexor power output in early stance, which was necessary to maintain the equinus tibia and found that the increased equinus posture results in reduced plantar flexor force requirements. The reduced ground reaction force (GRF) vector to the ankle joint center with greater angles of plantar flexion. contribute to the GRFs) is dependent on the current state of the system (i.e., the body segment orientations; [9]). Gait & Posture 27 (2008)Thus, it is not clear if the equinus posture associated with toe walking alters the ability of the plantar flexors to contribute to these functional tasks
