Knee-joint kinematics analysis using an optimal sensor set and a reliable algorithm would be useful in the gait analysis. An original approach for ambulatory estimation of knee-joint angles in anatomical coordinate system is presented, which is composed of a physical-sensor-difference-based algorithm and virtual-sensor-difference-based algorithm. To test(More)
Human foot is a complex musculoskeletal system. As it is impossible to directly measure the force of muscle attaching with limbs, a new quantitative method for dynamics analysis of human ankle muscle forces is presented by using the AnyBody Modeling System and a developed wearable motion and ground reaction force (GRF) sensor system. The sensor system can(More)
As standing up disability is increasing under the trend of population aging of many countries, a new rehabilitation trainer system for training and analyzing human lower limb athletic ability on sit-to-stand is presented in this paper. An impedance control method was introduced to assure patients safely and effectively stand up in their normal posture. In(More)
As it is inconvenient to directly measure tension forces of muscles attaching on limbs, a new quantitative method for estimating muscle forces of lower limb was presented based on a developed rehabilitation training system and AnyBody Modeling System. In the AnyBody Modeling System, which professionally concerns on musculoskeletal kinematic modeling and(More)
