Modular prosthetic limbs from the Applied Physics Laboratory

One man who lost forty years ago both hands last summer lucky enough. In the Applied Physics Laboratory (PSL) Johns Hopkins made his new limbs - two revolutionary modular prosthesis. Leslie Bo ran newfound hands, just thinking about what he wants to do.

As part of the program to create a revolutionary prosthesis, which started about 10 years ago, in June, held a two-week experiment in which participated and Leslie Bo. Before you get new dentures, he underwent surgery for reinnervation. Explains Albert Chi, an employee of the hospital Hopkins, this is a relatively new surgical procedure needed to be adjusted as the nerve endings, set neural connections and allow Leslie to control a prosthesis by thought.

Once Bo recovered after surgery, he returned to the lab and started training to use modular prosthetic limbs. First, Leslie worked with researchers on the recognition system impulses. Researchers need to fix as what muscles are reduced, with what frequency and power, how they interact. All this information is analyzed and then used to reproduce the movement with the help of prostheses. Bo then measured to make a suitable vest that would support the artificial hand and provides a connection to the nerves. While vest brought to mind, Leslie trained to control the virtual prosthetic simulator.

When the vest was completed and new hands attached to the shoulders Bo, he was ready to test the results of their training. Among other things, Bo was able to rearrange the shelf on the shelf mug, for which he had to coordinate as many as eight separate movements. Such actions have to make every day, but other prostheses do not give such an opportunity. A modular prostheses Leslie took only 10 days of training, which, in addition, indicate the nature of intuitive control of such actions.

The researchers suggest that the success of Bo with new dentures will surpass what he could achieve more traditional methods. What they did not expect was that the speed with which and how many actions he can master. Another important aspect: Bo turned simultaneously monitor a combination of several movements of both hands.

Details of the experiment can be seen in the video.
