The Received 4 January 2008 model is aimed at the reconstruction of motion trajectories of the shank, thigh and HAT Received in revised form 14 March 2008 (Head-Arms-Trunk) segments in sit-to-stand-motion using low cost inertial sensors. For Accepted 9 May 2008 this purpose the Extended Kalman filter is applied for fusion of model data and data Available online 21 May 2008 acquired through measurements. The simplifications, like motion constraint to sagittal plane, symmetry of movement and assumption of ideal joints are i
