A new robotic device called the Myomo e100, IS designed to help stroke patients regain motion in their arms.
The device, worn as an arm brace, works by sensing weak electrical activity in patients’ arm muscles and providing just enough assistance that they can complete simple exercises, like lifting boxes or flipping on light switches. By practicing such tasks, patients may begin to relearn how to extend and flex the arm, rebuilding and strengthening neurological pathways in the process.
“The device is designed to help get patients over a functional hump” so they can start moving the weakened arm again, said John McBean, a mechanical engineer who developed the technology with Kailas Narendran, an electrical engineer and computer scientist. (The two began the project in 2002, in a graduate robotics class at M.I.T.)
