A Development of an Evaluation System for Valgus Stress Test of the Elbow Using Three-dimensional Electromagnetic Sensor

Abstract

Performing competitions such as tennis and baseball can damage medial collateral ligament (MCL) of the elbow joint．This study aims to develop an evaluation system with high repeatability and reproducibility for the evaluation of MCL．We use a stress measurement system for quantifying stress load and three-dimensional electromagnetic sensor for acquiring three-dimensional position and attitude information for testing equipment． The developed system measured valgus stress test 5 times for three subjects, including detachment of instruments． Finally, the valgus stress can be measured with high reproducibility.
