Abstract

Under the aim of finding effective rehabilitation solutions, the difference between the extents of fatigue of each muscle used in different motions are compared. Previous research suggested methods for estimating muscle torque and muscle tension on the basis of a musculoskeletal model. As a result, it has become possible to quantitatively identify the extent of fatigue in each muscle during motion. Therefore, to evaluate muscle fatigue more quantitatively, driving power and angular momentum are focused on. Based on the driving torque of joints and the muscle torque calculated by using a three-dimensional musculoskeletal model, a method for calculating the driving power of joints and the angular momentum of a muscle is proposed. This method is applied to analysis of different motions. Moreover, fatigue of muscles is quantitatively analyzed on the basis of driving power and angular momentum.

Keywords

Angular momentum, driving power, driving torque, musculoskeletal model.
