Cervical spinal cord stimulation can elicit arm and hand movements through recruitment of proprioceptive neurons in the dorsal roots. In participants with cervical spinal cord injury, the spare roots bellow the lesion can be used to reactivate motor function. Decoding of motor intentions can be achieved through implantable electrocorticography (ECoG) devices.
In this study, the investigators will use an investigational system using ECoG signal recording over the motor cortex to drive muscle specific electrical epidural spinal cord stimulation (EES). The investigators will assess the safety and preliminary efficacy of this system in 3 participants.
