Artificial Arm

Prosthetist Robert Lipschultz tests out amputee Alfred Tennione's new Boston Digital Arm in the lab at Rehabilitation Institute of Chicago. Currently Tennione's artificial arm is activated with two contact points that sense surface electrical impulses or EMGs generated by muscle movement. There is also a manual switch he can activate with his other hand...Technicians and Dr. Todd Kuiken M.D. Ph.D. at Rehabilitation Institute of Chicago are working to add more contact points that will be activated by surface EMGs which can increase as Tennione's nerves continue to reinnervate the muscles used in the nerve-muscle graft surgery...Tennione's surgery earlier in the year essentially rerouted his nerve endings and grafting them into four separate regions of muscle near his amputation site. Electrical signals from these muscles or EMGs will be used to control a Boston Digital Arm..
