Before revision:  In less than five minutes of training, amputees were able to successfully control in real time a multi-articulate prosthetic arm (hand and wrist) to perform various activities of daily living. Preliminary implementation of the modified Kalman filter onto a portable, take-home system further demonstrates feasibility of the algorithm as a way to explore the functional and psychological benefits associated with long-term, at-home control of dexterous prosthetic hands.
After revision:  In less than five minutes . Conclusions: The MKF can be used to explore the functional and psychological benefits associated with long-term, at-home control of dexterous prosthetic hands.
