SYSTEM AND METHOD FOR DETERMINING USER INTENTION FROM LIMB OR BODY MOTION OR TRAJECTORY TO CONTROL NEUROMUSCULAR STIMUATION OR PROSTHETIC DEVICE OPERATION

摘要

Disclosed is a device for restoring motion to a person's paralyzed body part, for example, the person's hand. The device senses movement of another part of the person's body not affected by the paralysis, for example, the person's arm or shoulder. Motion sensors generate motion signals as the person moves the non-paralyzed body part. A processor stores information associating a predefined trajectory with a particular action, for example, closing the hand to grasp an object. The processor monitors the motion signals and, when the motion corresponds with the predefined trajectory, the processor energizes muscle stimulators connected with muscles that control the paralyzed hand to perform the action, for example, to cause the hand to close around and grasp the object.
