A real-time volitional electromyography (EMG) and stimulus EMG monitoring system integrated with electrical stimulator and artifact-suppression circuit is disclosed. The device includes an overall EMG amplifier and a stimulator, artifact suppression circuit, and analogue to digital converter. The signal process unit receives the stimulation parameters and controls the stimulator to generate constant current stimulation. The EMG amplifier with artifact suppressor reduces the artifact that caused by electrical stimulation and amplifies the overall EMG signal. The amplified overall EMG can be converted to digital data for further processing. This device can real-time extract the peak-to-peak amplitude of stimulus EMG as well as direct output the linear envelop form of volitional EMG after the removal of stimulus artifact indicating the torque generated from stimulation and voluntary contraction.本發明係一即時自主肌力與電刺激誘發肌力量測電路,其包括一整合式即時電刺激肌電訊號處理單元、一電刺激器、一具有刺激干擾抑制器的肌電訊號放大器、一類比數位轉換單元;該整合式即時電刺激肌電訊號處理單元控制該電刺激器對一使用者進行電刺激,該具有刺激干擾抑制器的肌電訊號放大器會將電刺激輔助動作時的混合肌電訊號去除刺激干擾;接著該整合式即時電刺激肌電訊號處理單元會由運算並輸出混合肌電訊號、刺激誘發肌電訊號和自主肌電訊號以便分析與應用。10...整合式即時電刺激肌電訊號處理單元11...電刺激器12...使用者13...具有刺激干擾抑制器的肌電訊號放大器14...類比數位轉換單元
