Abstract
A method for controlling digit movement of a prosthesis based on residual forelimb volitional pressures is provided. A filter is provided for discriminating from the distributed pressures to provide reliable digit control. The extracted commands can be used to control actuators in a hand prosthesis to restore biomimetic finger control to the user. Feature extraction algorithms can be based on signal amplitudes (peak amplitude or root mean square). Training signal validation can be based on cepstral encoding. The filter is trained under user supervision.
