Upper-limb amputation can greatly impairs function of patients, particularly those with above-elbow amputations. Electromyographic (EMG) signals have proven to be effective command sources for controlling externally powered upper-limb prostheses. The work presented here specifically investigates a method for predicting arm movements based on EMG signals from muscles in the upper arm and shoulder. With this approach, a patient may be able to control his or her transhumeral prosthesis more naturally and effortlessly than with current commercially available options.
