Restoring Motor and Sensory Hand Function in Tetraplegia Using a Neural Bypass System

About this trial

This is a trial to test the effect of a device called the Bidirectional Neural Bypass System on hand and wrist movement and sensation in individuals with chronic complete tetraplegia after high cervical SCI. If included in this trial, the participant will first receive neurological examinations and brain scans (functional magnetic resonance image (fMRI) and diffusion tensor image (DTI)). If eligible for continued participation, the participant will undergo surgery to implant electrodes into the brain, which can record brain activity and deliver stimulation to specific brain areas. After surgical recovery, the participant will undergo an X-Ray computed tomography (CT) scan and will be discharged from the hospital. After full recovery, the participant will attend 3x4-hour study sessions a week for 12 months to test hand and wrist movement and sensation. This trial does not have a control group.
