A Groundbreaking Experiment Gives A Double Amputee Two Mind-Controlled Prosthetic Arms. Watch Him Use Them For The First Time.

A Groundbreaking Experiment Gives A Double Amputee Two Mind-Controlled Prosthetic Arms.


A Colorado man made history at the Johns Hopkins University Applied Physics Laboratory (APL) when he became the first bilateral shoulder-level amputee to wear and simultaneously control two of APL’s prosthetic arms simply by thinking about moving his limbs. Experts say that the groundbreaking procedure could change the way prosthetics are used.

Les Baugh, who lost both arms in an electrical accident 40 years ago, trained his muscles to use the Modular Prosthetic Limbs (MPL), as the prosthetic arms are called, and was able to lift cups and perform a range of motions with each arm.

Before using APL’s limb system, Baugh had to undergo a surgery at Johns Hopkins Hospital known as targeted muscle reinnervation. Johns Hopkins Trauma Surgeon Albert Chi, M.D., explained:

It's a relatively new surgical procedure that reassigns nerves that once controlled the arm and the hand. By reassigning existing nerves, we can make it possible for people who have had upper-arm amputations to control their prosthetic devices by merely thinking about the action they want to perform.

After he recovered from the surgery, Baugh visited the Laboratory for training on the use of the MPLs. First, he worked with researchers on the pattern recognition system and then was fitted for a custom socket for his torso and shoulders that supports the prosthetic limbs and also makes the neurological connections with the reinnervated nerves.
