Instrumented evaluation of myoelectric control in a bilateral percutaneous hand grasp neuroprosthesis for spinal cord injured persons with tetraplegia


I. Abstract Stimulation was applied to both right and left hands to create simultaneous handgrasps using intramuscular percutaneous electrodes. It was controlled by myoelectric signals detected from both right and left sternocleidomastoid muscles in two persons with tetraplegia. The controller detected three levels of activation of the muscle: none, low and… (More)
