機能障害を改善するための筋力評価での工夫

In clinical practice, muscle weakness is often considered a functional disability similar to limitation of range of motion. We physical therapists use manual muscle testing (MMT) described by Daniels et al. for the general assessment of muscle weakness. This test quantitatively assesses muscle strength by the amount of joint movement, muscle contraction, and the effect of gravity and resistance. However, it is not possible to evaluate the strength of individual muscles involved in a single joint movement, or to separate a single muscle into fibers with different actions. In other words, it is difficult to narrow down the individual muscles and muscle fibers that are weak using MMT results. In this paper, we examine the possibility of evaluating muscle weakness using MMT for knee extension, and hip abduction by changing some of the test positions and the direction of manual resistance based on kinematics. Each of these proposed test positions is presented based on electromyogram data.
