Quantitative evaluation of unrestrained human gait on change in walking velocity.

In human gait motion analysis, which is one useful method for efficient physical rehabilitation to define various quantitative evaluation indices, ground reaction force, joint angle and joint loads are measured during gait. To obtain these data as unrestrained gait measurement, a novel gait motion analysis system using mobile force plates and attitude sensors has been developed. On the other hand, a human maintains a high correlation among the motion of all joints during gait.

Gait motion analysis in the unrestrained condition of trans-femoral amputee with a prosthetic limb.

Trans-femoral amputees must regain moving pattern by refined rehabilitation program using ground reaction forces, joint angles and joint moments applied on a prosthetic limb. On the other hand, understanding those loads and kinematic variables is indispensable for gait analysis based on the biomechanical consideration of trans-femoral amputees. However, conventional prosthetic gait training systems cannot measure long continuous walking motions.

Calculation of joint reaction force and joint moments using by wearable walking analysis system.

In gait analysis, which is one useful method for efficient physical rehabilitation, the ground reaction force, the center of pressure, and the body orientation data are measured during walking. In the past, these data were measured by a 3D motion analysis system consisting of high-speed cameras and force plates, which must be installed in the floor. However, a conventional 3D motion analysis system can measure the ground reaction force and the center of pressure just on force plates during a few steps.

Development of a novel six-axis force/moment sensor attached to a prosthetic limb for the unrestrained gait measurement.

Since the number of trans-femoral amputees has increased by industrial or traffic accidents in modern society, a prosthetic limb has been required. In this case, those amputees must regain moving pattern by efficient gait training using load conditions on a prosthetic limb as quantitative evaluation indices. However, conventional gait training systems cannot measure long continuous walking motions.

Biomechanical consideration based on the unrestrained gait measurement of trans-femoral amputee with a prosthetic limb.

Trans-femoral amputees must regain moving pattern by refined rehabilitation program using loads applied on a prosthetic limb. On the other hand, understanding those loads is indispensable for biomechanical consideration of trans-femoral amputees.
