Upper body prostheses have definitely come a long way. For those with amputations at the hand or wrist, gone is the time when the only option was a hook or some other horrific replacement.
Touch Bionics is a company which makes myoelectric prostheses to replace upper body amputations at the hand and wrist. Myoelectric prostheses are a life-altering product which attach at the remaining part of the limb and are triggered my muscle signals from intact muscle. Touch Bionics has a number of products, and has recently updated their i-limb ultra bionic hand to the i-limb ultra revolution, which includes a rotating thumb and four other articulating digits for up to 36 types of grasp. A mobile app allows the control of these grip patterns, which includes 12 possible customized grips. In addition, a silicone skin-like covering is available in a number of colors to allow for improved grasp and a more skin-like feel.
As we know, hands are very complex body parts with multiple joints that are responsible for numerous different movements, functions, and types of grip. To recreate these movements and try to mimic the function of human fingers, particularly the thumb, is quite difficult. While the loss of a hand naturally causes a great disability, a great product such as this allows an individual to perform a multitude of daily task such as tie their shoes, grasp a pen, or use a smartphone.
