Abstract :
Functional electric stimulation (FES) is one of good rehabilitation tools in helping paraplegic patients to regain their abilities to walk with walker. To monitor the body posture of patients, it´s important to get the magnitudes and directions of the hand support forces - handle reaction vector (HRV). A wireless dynamometer walker system is proposed in this paper, which mainly uses two CRM2400 modules for wireless communication. The system´s diagram, the interface circuit between a single chip microcomputer and wireless module, the communication protocol, and software working flowchart are given. The system runs well.
