title: Comparison of experimental and analytical torque-angle relationships of the human elbow joint complex.
abstract: The human elbow joint complex (EJC) is an intricate joint that is currently being modeled with eight musculotendon actuators for the analysis of flexion-extension and pronation-supination movements. The musculotendon length (LMT), musculotendon velocity (VMT), and muscular moment arm (MA) for each actuator have been investigated based on joint anatomy and joint angle position. Musculotendon parameters necessary for the muscle model have been collected from various sources. These parameters, along with the musculoskeletal geometry, are used in a static muscle model to compute the force and joint torque generated by each muscle. The results are plotted as torque-angle curves and compared with experimental joint torque data.
