The variation in stride length is an important index of gait stability. The evaluation requires a device that can accurately measure the stride length during ground walking. However, there are currently no practical and reliable measurement systems f

Perturbations in sitting posture, represented by the center of mass (COM) of the upper body, provide critical information for analyzing balance control. While the COM is generally measured by an optical motion capture system, it is not practical. In

Accurate estimation of the center of mass is necessary for evaluating balance control during quiet standing. However, no practical center of mass estimation method exists because of problems with estimation accuracy and theoretical validity in previo

As a method for the balance assessment, a steady-state response of a subject standing on the support surface oscillating horizontally back and forth at a single frequency has been studied. While past studies on the method have focused on the kinemati

Center of pressure (COP) has been one of the most popular index for balance evaluation in quiet standing. However, the balance evaluation based on COP has been limited due to its accuracy. For accurate balance evaluation, an estimation method of the
