Abstract

Upper limb prostheses are increasingly resembling the limbs they seek to replace in both form and functionality, including the design and development of multifingered hands and wrists. Hence, it becomes necessary to control large numbers of degrees of freedom (DOFs), required for individuated finger movements, preferably using noninvasive signals.While existing control paradigms are typically used to drive a single-DOF hook-based configurations, dexterous tasks such as individual finger movementswould require more elaborate control schemes.We showthat it is possible to decode individual flexion and extension movements of each finger (tenmovements) with greater than 90% accuracy in a transradial amputee using only noninvasive surface myoelectric signals. Further, comparison of decoding accuracy from a transradial amputee and able-bodied subjects shows no statistically significant difference (p
