About this trial

This trial is recruiting individuals with impaired hand function due to cervical (neck area) spinal cord injury to test using small electrodes (NeuroPort Arrays) implanted into the brain. The main goal of this trial is to test for safety. Participants will also be evaluated for effectiveness of the device. With the electrodes in the brain, participants can be trained to send nerve signals to a computer that translates them to movement; this can then be used to control a variety of devices or computer displays.
