Beschreibung
Zusammenfassung:	A compact, powered, orthotic device for pediatric use enables the user to control relative motion of the upper arm and the forearm about the elbow and grasping motions of the thumb and fingers. The device is powered by a set of battery-driven, backdrivable linear actuators that are positioned remotely from an arm of the subject. Control of motion of the device by the subject occurs by means of electromyographic signals from a sensor array in contact with skin on the arm of the subject. The sensors in the sensor array may be held in place on the forearm, on the upper arm, or at any other convenient location on the arm.
