This condition often is responsive to physiotherapy. It has become very common to include the use of a Functional Electrical Stimulation (FES)-Cycling System as part of their physiotherapy. Success has brought on the need to improve the systems and modify the equipment for the next generation of FES. In this study we explore an FES-cycling system that applies real-time bio feedback control. Using EMG as our feedback control signal to adjust the FES output intensity to the requirements of the subject. To do this, we combined it with a FPGA to make this system react in real-time. When EMG is measured, the system now has to react, opting to apply ES or not. During ES, the Stimulation Artifacts (SA) will also be removal. Monitoring the subject’s EMG state, in real-time, automates our system, adjusting the machine to respond to the individual subject by continually adjusting the timing and amplitude of ES and results in more effective treatment.
