MUSCLE PHYSIOLOGY REDUCES THE FEASIBLE TORQUE SET DURING HUMAN GAIT

INTRODUCTION All neuromusculoskeletal systems can be mathematically described as linear mappings from a neural command space to an eventual mechanical wrench space [1]. In nature, the set of feasible neural command inputs is larger than the set of feasible mechanical outputs [2] and different sets of neural commands can achieve the same motion. The culmination of mechanical actions that a joint system produces can be described as the endpoint wrench space. To achieve any particular endpoint wrench set during motor tasks, neural commands must define actions producing muscle forces, which in turn produce joint torques. The hypothetical set of all possible joint torques is referred to as the Feasible Torque Set (FTS) [2]. The FTS sensitivity to physiological parameters of muscle fiber length (l m ) and fiber velocity (v m ) is not well understood. Identifying relationships between force-length-velocity properties and FTS contributes to our understanding of neural control.
