Analysis of Human Joint Forces in Standing Posture

【摘要】 Using the software Anybody Modeling System, a human static-standing musculoskel etal model based on inverse dynamics is presented, which are defined as segm ents, muscles and joints as elements. Simulation is based on data obtained from experiments using motion capture system VICON and force plate AMTI. In the model AnyBody Modeling System is introduced to help solve the redundancy problem and obtain results of muscle activities, muscle forces and joint forces. From the mo del, hip and knee joint forces could be analyzed under normal standing posture. Also, activities of the musculus rectus femoris and several other muscles of the lower limbs can be obtained. From the results it could be concluded that stress es at joints are much stronger than theoretical reasoning because of the functio ns of relevant soft tissues such as muscles, tendons and so on. Results show tha t joint forces from the simulations are in good conformation with previous exper imental researches. And this complicated model would be of use for better unders tanding human body functions.更多还原
