The monitoring of tendon tension with an implantable intratendon probe and its use in the control of neuroprostheses.
The use of a probe measuring tendon tension for the purpose of controlling a neuroprosthesis suited to spinal cord injured persons is investigated. The implanted probe detected inwardly directed radial force exerted by the tendon as the result of longitudinal tension. Varying types of load were applied to the tendon in order to measure static and dynamic parameters of the probe within the tendon. The results are discussed with respect to the potential use of the probe, within an active muscle's tendon, as a hand grasp neuroprosthesis controller. In addition, use of the probe to monitor electrically stimulated paralyzed muscle for the augmentation of closed loop control schemes is discussed.
