Are Joint Torque Models Limited by an Assumption of Monoarticularity?

Are joint torque models limited by an assumption of monoarticularity?

This study determines whether maximal voluntary ankle plantar flexor torque could be more accurately represented using a torque generator that is a function of both knee and ankle kinematics. Isovelocity and isometric ankle plantar flexor torques were measured on a single participant for knee joint angles of 111° to 169° (approximately full extension) using a Contrex MJ dynamometer. Maximal vol...

Joint Torque Sensory in Robotics

Joint Torque sensory Feedback (JTF) can substantially improve the performance of a robotic system. JTF makes it possible to achieve dynamic control of a robotic manipulator without the need for modeling its link dynamics. Moreover, it has been proved that JTF can achieve a precise torque tracking in a manipulator joint by compensating the e ect of joint friction and actuator nonlinearities. Des...

Uncertainty of knee joint muscle activity during knee joint torque exertion: the significance of controlling adjacent joint torque.

In the single-joint torque exertion task, which has been widely used to control muscle activity, only the relevant joint torque is specified. However, the neglect of the neighboring joint could make the procedure unreliable, considering our previous result that even monoarticular muscle activity level is indefinite without specifying the adjacent joint torque. Here we examined the amount of hip...
