Neuroscience and Robotics Return Limb Function

A new non-invasive neurorobotic system, combining advances in neuroscience and robotics, is being used to restore independence to individuals after loss of neurological function or atrophy.

The e100 NeuroRobotic System is a user-controlled, wearable robotic brace designed to non-invasively treat arm dysfunction cause by stroke. Clinically shown to improve mobility in patients ranging from 4 to 21 years after stroke onset, the robotic brace helps patients relearn how to move by enabling them to self-initiate and control movement of hemiparetic (partially paralyzed) arms using their biological signals. No electrical stimulation or invasive procedures are employed to help patients relearn how to control their weakened muscles and achieve more normative movement patterns.

When a patient's electrical muscle activity signal fires in response to attempted movement, the device senses the signal from the skin's surface. The system then employs advanced robotics to reward the patient with feedback in the form of actual motion. Since the presence (or absence) of a person's Electromyography (EMG) signal determines motion, patients using the Myomo device may stop and re-adjust positioning during real-time execution of a targeted exercise as they work toward muscle re-education training. Adjustable system parameters allow therapists to set and vary assistance levels in proportion to patient ability. The e100 NeuroRobotic System, a product of Myomo (Boston, MA, USA) received a Best of What's New Popular Science magazine 2007 award.

"Everyone at Myomo is very excited to be recognized by Popular Science as a company that is revolutionizing healthcare with NeuroRobotic's technology,” said Thomas Glover, CEO of Myomo.
