Todd Kuiken: A prosthetic arm that "feels"

Physiatrist and bioengineer Todd Kuiken and his team have developed a prosthetic limb that "feels". Current prosthetic limbs have limited function and many are limited to one motion. The problem is trying to decipher the thought processes of the nervous system in order to direct the prosthetic limb. Many research labs are heading into this direction in the form of neuro interfaces. However, these technologies are still quite far off before they are able to be used in the clinic. Kuiken has gotten around this problem by developing an interface that interfaces with the arm nerve fibers. It works by surgically cutting and moving the arm nerve fibers to the patient's chest and developing an interface that senses the nerve impulses on the chest. This allows the patient to move the arm just by thinking. The prosthetic limb has a high level of motion and even allows the patient to make their wrist turn 360 degrees! (watch the video)
