A team of engineers and neurologists led by Sunil Agrawal, professor of mechanical engineering and of rehabilitation and regenerative medicine, designed a comfortable and wearable robotic neck brace that incorporates both sensors and actuators to adjust the head posture, restoring roughly 70% of the active range of motion of the human head. Using simultaneous measurement of the motion with sensors on the neck brace and surface electromyography (EMG) of the neck muscles, it also becomes a new diagnostic tool for impaired motion of the head-neck. Their pilot study was published August 7 in the Annals of Clinical and Translational Neurology.
The brace also shows promise for clinical use beyond ALS, according to Agrawal, who directs the Robotics and Rehabilitation (ROAR) Laboratory. "The brace would also be useful to modulate rehabilitation for those who have suffered whiplash neck injuries from car accidents or have from poor neck control because of neurological diseases such as cerebral palsy," he said.
Knowledge - Professor - Agrawal - Team - Time
"To the best of my knowledge, Professor Agrawal and his team have investigated, for the first time, the muscle mechanisms in the neck muscles of patients with ALS. Their neck brace is such an important step in helping patients with ALS, a devastating and rapidly progressive terminal disease," said Hiroshi Mitsumoto, Wesley J. Howe Professor of neurology at the Eleanor and Lou Gehrig ALS Center at Columbia University Irving Medical Center who, along with Jinsy Andrews, assistant professor of neurology, co-led the study with Agrawal. "We have two medications that have been approved, but they only modestly slow down disease progression. Although we cannot cure the disease at this time, we can improve the...
