Myoelectric control of powered upper limb prostheses

失去一只或两只手臂是一种严重的残疾，严重限制了接受上肢截肢的人的日常能力和互动。在加拿大，大约有10,000名上肢截肢患者。合适的截肢假体置换(S)将增强他们的生活自理能力，使他们能够进行更多样化的就业，并提供更多机会享受积极的生活方式。肌电假体使用来自残肢肌肉的肌电(EMG)信号(肌肉收缩时产生的电信号)来控制电动手臂关节。肌电的使用提供了一种非侵入性的方法，可以建立与神经肌肉系统的自然接口，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.
