New research presented at the American Stroke Association’s International Stroke Conference in Los Angeles shows that robot-assisted therapy is effective in improving arm and shoulder mobility in patients who are paralyzed as a result of a stroke.
According to the study, 60 patients with hemiplegia (paralysis on one side of the body) due to a stroke were given physical therapy. Half of the group received robot-assisted therapy using a Reo Therapy System by Motorika Ltd. (Caesarea, Israel), which repeatedly moves the forearm in various pre-programmed directions. The other half spent the same amount of time undergoing traditional rehabilitation.
According to the study:
Patients on robotic therapy showed marked improvement in two measures of upper extremity function: the Fugl-Meyer flexor synergy score, a 0 to 12 scale with higher numbers reflecting recovery of voluntary arm movement; and the Fugl-Meyer shoulder/elbow/forearm score, a 0 to 36 scale with higher numbers reflecting recovery of motor function in the shoulder, elbow and forearm.
The study suggested that the success of robot-assisted rehabilitation may be due to the fact that, unlike human physical therapists, robots can carry out repetitive exercises with exactly the right movement pattern every time.
