Abstract
The joint strategy is one of the primary representations for the balance analysis of standing. Although the ankle joint strategy and the hip joint strategy are generally defined from the viewpoint of the neurological field, it is hard to estimate the contribution of the joint strategies from a test result. To solve the problem, this study defined the joint strategy from kinematics and proposed to evaluate the contribution of the strategies from the acceleration of COM of lower and upper bodies. The method can be applied by using the motion capture system, however, there is a practical difficulty in clinical tests. For easy measurement, this study demonstrated the estimation method of modes of joint strategy from the measurement of a force plate and an inertia measurement unit (IMU). The validity of the estimation method was verified by standing tests in comparison with motion capture measurement.
