| Summary: | 碩士 === 國立中正大學 === 機械工程系研究所 === 107 === The purpose of this study is to prevent degenerative arthritis of the knee. Two systems were proposed: the kneepad system and the intersegmental force measurement system.
In the kneepad system, inertial measurement units (IMU) are mounted at the upper and lower ends of the kneepad, which can record user’s thigh and shank angle data in mobile phone through Bluetooth. The system can be applied to measure the flexion angle of the knee joint and detect gait and swing phases during level-ground walking.
In the intersegmental force measurement system, the human trunk, limbs and joints are modeled as a parallel manipulator, and the kinematics and dynamics are formulated based on Newton-Euler Method and the Zero Moment Point (ZMP) Theory. Thus, the IMUs mounted on the each mass centers of the limbs to collect posture information and the intersegmental forces can be evaluated. The correctness and feasibility of the system are verified by the experimental values of the load-cell shoes and the simulated values of the intersegmental force measurement system.
