MBS Dynamics for Assessing the Reaction Forces and Torques in Elbow Joint

The paper presents the multi-body system method (MBS) as a proper tool for assessing the magnitude of reaction forces and torques in human upper limb joints. Forward dynamics is used and the reaction forces are determined in different simulating conditions. The steps to be followed in MBS modeling are presented together with the principles of modeling the bones, the muscles and the joints of the human upper limb. The simulation model provides results for the reaction forces and torques in the elbow joint during the flexion of the forearm.
