Simulation of the Length Change in Muscles During the Arm Rotation for the Upper Brachial Plexus Injury

This work presents a 3D upper limb musculoskeletal model and the simulation of arm rotation for the case of a healthy human subject and one with upper brachial plexus injury (UBPI). Then, the length change in muscles and range of movement was obtained and compare for both cases. The results show a notable difference between the two cases and can be used to define an effective rehabilitation therapies for this injury.
