The Basic Structure Of Electromyographic Biofeedback Instrument

The electromyographic biofeedback device mainly consists of hardware circuits and software. The hardware of the electromyographic biofeedback device mainly includes electromyographic signal acquisition and electrical stimulation. Among them, the electromyographic signal acquisition part includes detection electrodes, preamplifiers, signal filtering circuits, and analog-to-digital conversion circuits. The electrical stimulation part includes a DA conversion circuit and an electrical stimulation circuit. Some software calculates the effective value of the biological electromyography signal based on reliable feedback. Determine the intensity and frequency of the output muscle electrical stimulation signal based on the effective value and time of the biological electromyographic signal.
