Abstract
Objective: In order to promote paralyzed patients’ recovery of their motor function, we designed this functional electrical stimulation (FES) signal generator. Method: We used AT89C52 MCU and digital analog converter as the core to compose hardware system. By analyzing the time domain characteristics of common waveforms and the movement-related neural signals, we designed the corresponding MCU program, then the expected waveforms can be generated as signal sources of this therapeutic apparatus. Results:This signal generator is able to produce series of waveforms in the time domain, such as sine wave, rectangular wave, triangular wave signal, and neural signal bands related with movement .Conclusion: Compared with the traditional signal generators [1], this signal generator has the advantages of simple structure, complete functions, low cost and convenience. Using movement-related neural signals which were collected from animal experiments as signal sources is helpful to induce the coordinated movement and reduce the muscle fatigue.
