Establishing biomechanical model of human body for restoring standing functions

This work presents a five-segment biomechanical model of the human body for paraplegics of spinal cord injury (SCI) with thoracic nerve injury. When the functional electrical stimulation (FES) system is used to restore sit-to-stand function, the biomechanical model can be used to analyze the position, force, and moment of the human body at every joint through inverse dynamics. A series of data taking from SCI patient under FES of restoring sit-to-stand function are implemented on the model. The results help realize the role of each joint and muscle in the sit-to-stand process so as to improve the rehabilitation in the future plan.
