Myoelectric control of powered upper limb prostheses

失去一只或两只手臂是一种严重的残疾，严重限制了上肢截肢者的日常能力和互动。加拿大大约有1万名上肢截肢患者。一个合适的义肢替代物可以提高他们照顾自己的能力，使他们有更多样化的就业机会，并提供更多机会享受积极的生活方式。肌电假肢利用残肢肌肉的肌电图（EMG）信号（肌肉收缩时产生的电信号）控制机械手臂关节。肌电图的使用提供了一种非侵入性的方法来建立神经肌肉系统的自然界面，以控制肢体失去的功能。

The loss of one or both arms is a major disability that profoundly limits the everyday capabilities and interactions of individuals with upper-limb amputation. There are approximately 10,000 patients in Canada with an upper limb amputation. A suitable prosthetic replacement of the amputated limb(s) would enhance their ability to care for themselves, enable a more diverse range of employment, and provide more opportunities to enjoy an active lifestyle. Myoelectric prostheses use the electromyogram (EMG) signals (the electrical signals generated during muscle contraction) from residual limb muscles to control motorized arm joints. The use of EMG offers a non-invasive means of establishing a natural interface to the neuromuscular system to control the lost functions of the limb.
