THE MEASUREMENT AND APPLICATION OF THE RELATIONSHIP BETWEEN ELBOW ANGLE AND TORQUE
Keywords: joint tensiometer, elbow, angle-torque relationship
AbstractThe elbow joint torque is correlated with the joint angle in a certain relationship. In order to understand the relationship between the elbow angle and the torque, we designed a static elbow tensiometer to measure the elbow angle and the torque. After a series of testing, we found that the accuracy and repeatability of the joint tensiometer performed well. Fifty-one healthy subjects performed maximal voluntary elbow flexion and extension in the joint tensiometer. In elbow flexion, the maximal torque produced at the 110-degree elbow angle. In elbow extension, the maximal torque produced is at the 30-degree elbow angle. The more elbow angle increases, the less torque is produced.
