A transducer for measurement of finger joint torques

Abstract

A device for measuring torques generated about the joints of the fingers has been developed. The design utilizes a parallelogram construction that allows the device to fit different sizes of hands. The device has the capability to measure isometric moments generated about the MP, PIP and DIP joints of a single digit. Four of these devices can be used to make simultaneous measurements of all the moments generated about all three joints of the four fingers. The device also acts as a splint, allowing each joint to be positioned and locked at any angle through the range of motion of the joint. This device will be utilized in the synthesis of grasp patterns using functional electrical stimulation.<>
