| Research Abstract |
In clinical applications, the quantitative analysis of gait variability using kinematic and kinetic characterizations can be helpful to medical doctors in monitoring patient recovery status. A camera system and a stationary force plate can only accurately measure complete ground reaction force(GRF) and body orientations during a few steps, but data on successive gait measurements including 3D force and motion in different environments is really desired by clinical researchers and doctors. We have developed an urethra light and thin mobile force plate and a wearable GRF sensor system. Experimental results verify that the developed system can be used to measure the triaxial force with acceptable precision. Integrating developed force sensors and inertial sensors, an application trial for successive gait measurements was carried out. Results of the trial showed usefulness of the proposed system.
