Functions of hip joint muscles.
The relative torque components (percentages of total hip torque) of 26 hip muscles about three joint axes were calculated using a human multibody model to determine muscle actions as a function of hip joint angle. It was demonstrated that the muscle actions obtained from this straight line model of hip musculature were in good agreement with published functions; the data on muscle function changes during hip joint motions exceed the data available in the literature and could extend the anatomical knowledge which is available today.
