Robotic Brace Helps Stroke Patients

Posted 22 Mar 2007 at 23:49 UTC by Rog-a-matic Share This

Brain cell destruction following a stroke is common and often leads to loss of some motor function. Repetitive exercise therapy is then used to recruit other neurons to take on the task. MIT's robotic brace helps exploit this under-appreciated neural adaption by strengthening the feedback loop between the brain and limbs. EMG sensors within the brace monitor muscle activity and command actuators to assist with the desired motion. A study to appear in the April 2007 issue of the American Journal of Physical Medicine & Rehabilitation showed the robotic brace improved severely impaired arm function by 23% on average and greatly reduced muscle tightness.
