Researchers Aiming to Produce a Hand-Wrist Prosthesis with Two Degrees of Freedom From: Rehab Management - 03/03/2017 A team of researchers are aiming to provide a way for hand-wrist prostheses to move more naturally by enabling the hand and wrist to work simultaneously—known as two degrees of freedom—using electrical impulses generated by remnant muscles in the forearm. Traditional prostheses only work with one degree of freedom—that is, either the hand or the wrist can be in motion at any one time. The work is currently focused on how to translate signals picked up from muscle activity in the forearm into appropriate movements of the hand and wrist prostheses. They began by collecting data from 64 or more electrodes, but recognizing that a device with that many inputs could be burdensome or impractical, they are attempting to achieve the same effect with as few as four electrodes while also improving functionality.
