| Outline of Final Research Achievements |
A method of estimating lower limb joint torques by using inertial sensors without ground reaction force and 3D motion measurement system were examined for squat and sit-to-stand movements in the sagittal plane. The method estimated lower limb joint torques by using segment inclination angles measured with inertial sensors and an assumption of no external force to the top segment. The proposed estimation method was shown to be feasible from results of comparison of estimated joint torques to those estimated by ground reaction force and data from 3D motion measurement system. An estimation method of the number of strokes and push cycle during wheelchair propulsion using an inertial sensor attached on the upper arm was shown to be useful. Timings of hand contact on pushrim and hand release from it was suggested to be possible with inertial sensors. An estimation method of generated power in wheelchair propulsion by users were examined and problems to be solved were confirmed.
