一種新型設(shè)備能夠幫助腦卒中患者大腦某部分重新學(xué)習(xí)去激活或者重新學(xué)習(xí)自發(fā)性地控制肉。這種設(shè)備設(shè)計(jì)用于患者在自己家中進(jìn)行治療，已經(jīng)獲得了美國食品藥品管理局的許可。

Biomove3000系統(tǒng)能夠檢測(cè)腦中風(fēng)后持續(xù)癱瘓肌肉極其微小的肌電圖（EMG）信號(hào)，并且使用這些微小信號(hào)啟動(dòng)傳導(dǎo)至肌肉的電刺激脈沖，患者從而產(chǎn)生真實(shí)的肌肉運(yùn)動(dòng)。如果由于腦中風(fēng)的損害不能產(chǎn)生規(guī)則電脈沖，或者電刺激不能傳導(dǎo)至肌肉，就不會(huì)發(fā)生正常的肌肉收縮。殘余肌電圖信號(hào)通常非常微小不足以控制肌肉。這就會(huì)導(dǎo)致不可逆轉(zhuǎn)的損害以及肌肉功能的喪失，導(dǎo)致癱瘓產(chǎn)生爪型手以及下垂足。

在幾乎所有腦中風(fēng)病例中，仍然有非常少量的電刺激能夠傳導(dǎo)至肌肉。放置在癱瘓肌肉上的貼附電極能夠檢測(cè)到少量殘余肌電圖信號(hào)。Biomove設(shè)備然后將這些微小信號(hào)放大，當(dāng)達(dá)到內(nèi)部預(yù)置觸發(fā)水平的時(shí)候，嵌入式刺激器將電刺激回傳給相同的肌肉。然后這些肌肉就可以象患者自己大腦信號(hào)“指導(dǎo)”一樣的作出反應(yīng)。

患者使用這種方法來康復(fù)癱瘓的手或者足部肌肉。這種Biomove3000設(shè)備是由Curatronic公司(Hashmonaim, Israel)研制開發(fā)的。這種形式的腦中風(fēng)康復(fù)方法叫做肌電圖觸發(fā)的神經(jīng)肌肉電刺激（electromyographic-triggered neuromuscular electrical stimulation）。
 
Device for Stroke Rehabilitation
 
A new device helps stroke patients re-learn which part of the brain to activate and re-develop spontaneous muscle control. The device, designed for home therapy, has been cleared by the U.S. Food and Drug Administration (FDA).

The Biomove 3000 system detects extremely small electromyographic (EMG) signals that persist in paralyzed muscles after a stroke and uses these tiny signals to initiate an electrical stimulation impulse to the muscles, resulting in actual muscle movement by the patient. If regular electrical impulses are not generated or can no longer reach muscles due to stroke damage, normal muscle contraction becomes impossible. The “l(fā)eftover” EMG signals are often very small and unable to control muscles. This can lead to irreversible damage and loss of muscle function, resulting in paralysis causing a claw hand or dropped foot.

In almost all cases of stroke, there is still a very small amount of electricity that reaches the muscles. These small leftover EMG signals are picked up by stick-on electrodes placed over the paralyzed muscles.

The Biomove device then amplifies these small signals and when an internal preset trigger level is reached, the built-in stimulator returns an electrical stimulation impulse to the same muscles. The muscles now respond as originally “instructed” by the patient’s own brain signal.

Patients use this method to rehabilitate the muscles of an otherwise paralyzed hand or foot. The Biomove 3000 device was developed by Curatronic Ltd. (Hashmonaim, Israel). This form of stroke rehabilitation is known as EMG-triggered NMES (neuromuscular electrical stimulation).
