To provide a system and a method for determining user intention from limb or body motion or trajectory to use them to control neuromuscular stimulation or prosthetic device operation.SOLUTION: Disclosed is a device for restoring motion to a person's paralyzed body part. The device senses movement of another part (e.g., the person's arm or shoulder), of the person's body not affected by the paralysis. 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 (e.g., 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 to control the paralyzed hand to perform the action (e.g., to place the hand around an object, close the hand, and grasp the object).SELECTED DRAWING: Figure 1
