Abstract
To overcome limitations of a traditional gait analysis laboratory, in which stationary force plates and camera system can not measure more than one stride, in this paper, we propose a three-dimensional gait analysis system (M3D) composed of mobile force plates and motion sensors. Coordinate transformation from local coordinate system of M3D to global coordinate system is implemented by using measurements of the mobile force plate. A stick-chain model was built to visually analyze three-dimensional human gait and joint trajectories, and triaxial joint moments during gait can be calculated.
