Study on wireless dynamometer walker system

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.
