Jan Scheurmann, a 53 year old quadriplegic who is paralyzed from the neck down, recently managed to control a prosthetic arm with her mind to grasp and move objects with ease.

Two sensors were implanted in her brain that pick up electrical signals from around 200 individual brain cells, which later translate into commands that are used to move the arm and grab objects. The co-ordination, skill and speed she achieved only after 14 weeks of training (she was picking up objects on the second day!!) was almost similar to that of an able bodied person.

The next plan is to attach the prosthetic arm to Jen’s wheelchair so that she could use it on a daily basis. There have been attempts to give sensation to the prosthetic arm as well so that Jen could feel the sense of touch.

This development is huge for people with spinal cord injuries, amputees, and quadriplegics. We saw something similar earlier this year, and looking at the progress, we should see a lot more action in this area in the coming years!
