Physiologic Approach for Control of Hand Prostheses

Several efforts have been carried out in the recent past in order to develop artificial hands controllable by the voluntary activities of the subjects and able to restore lost hand functions. One of the bottlenecks is represented by the difficulty of extracting the information desired in an effective and natural way. Electromyographic (EMG) signals can represent an interesting solution because they are easy to record and can allow the user to control different robotic systems.
