A Hand Load Estimation Method for Anteflextion by Using The Muscle Hardness Sensor

Abstract

This study aims to develop of wearable sensor system, and propose an estimation method of lumbosacral alignment and lumbar load caused by changes in posture. Need to use the hand load for lumbar load estimation. Therefore, the hand load estimation method is developed by using muscle hardness sensor. By using this method, the hand load can be estimated with enough accuracy.
