A development of a measurement system for the positional relationship between the radius and the ulna with wrist rotation by attaching an electromagnetic sensor to the wrist.

Abstract

In sports using racquets such as tennis, the triangular fibrillary cartilage complex (TFCC) can be injured by the action of towing, compression, twisting of the wrist. To treat triangular fibrocartilage complex (TFCC), we aim to develop a device that can quantitatively evaluate the behavior during wrist rotation. In this research, we develop a system to measure the positional relationship between the radius and the ulna with wrist rotation by attaching an electromagnetic sensor to the wrist. In the experiment, the behavior of the left and right wrists when turning was evaluated in three healthy adults.
