    A device for enhancement of the grip in C5/6 spinal cord lesioned tetraplegics is under development. It uses the myoelectric signal from the paretic wrist extensor for control of electrical stimulation of the same muscle. The tetraplegics shall with the device be able to obtain a passive grip between the thumb an the index finger by extension of the wrist. Surface electrodes are used for myoelectric recording and stimulation. Main problems are filtering of the recorded signal and stimulation. Solutions to these problems are addressed and discussed.
