Are joint torque models limited by an assumption of monoarticularity

摘要: This study determines whether maximal voluntary ankle plantar flexor torque could be more accurately represented using a generator that is function of both knee and kinematics. Isovelocity isometric torques were measured on single participant for joint angles 111° to 169° (approximately full extension) Contrex MJ dynamometer. Maximal was by 19-parameter two-joint angular velocities with the parameters determined minimizing weighted root mean square difference between function. The 10 N-m or 3% maximum torque. accurate representation than an existing single-joint where differences 19% found. It concluded when flexed 40°, necessary.
