The Center For Bionic Medicine
About the Center for Bionic Medicine
The Center for Bionic Medicine (CBM) is a research program at the Rehabilitation Institute of Chicago (RIC) based on over 20 years of research. The goal of CBM is to improve function and quality of life for people who have suffered limb loss.
Currently, individuals who have undergone amputation are only able to operate one motion at a time with myoelectric prostheses. CBM has pioneered a technique called "targeted reinnervation" to improve myoelectric prosthesis function. With this technique, amputated nerves are transferred to spare muscle and skin in an amputee's residual limb. The nerves grow into the muscle to provide additional control signals for the operation of a prosthesis. This allows patients to control multiple functions in their prosthesis at the same time in an easier, more natural manner.
“Sensory reinnervation” also takes place following the targeted reinnervation procedure; the patient feels touch to the reinnervated skin as being applied to their missing limb. This may allow the amputee to actually "feel" what they are touching with a prosthetic hand. Through these studies, CBM is working to develop a state-of-the-art prosthesis that includes shoulder, elbow, wrist and hand components, as well as haptic interfaces to provide the sense of touch.

Targeted Reinnervation for Transhumeral Amputees
In collaboration with Dr. Gregory Dumanian, of Northwestern University’s Department of Plastic Surgery, CBM is pleased to now offer a comprehensive surgical training video on targeted reinnervation for the transhumeral amputee.
