Restorative Neuromodulation for Upper Extremity Functions

About this trial

This is a clinical trial to investigate the effect of trans-spinal electrical stimulation (tsES) on reaching and grasping in individuals with chronic cervical (neck area) spinal cord injury or traumatic brain injury. tsES is a non-invasive electrical stimulation technique that applies surface electrodes to the skin. This electrical current is thought to activate nerve circuits in the spinal cord; this might improve function of arms, hands and fingers. This study will measure the effectiveness of tsES on motor recovery and muscle strength. Researchers hope to better understand how the stimulation works, using high-resolution nerve measurements (electrophysiology) and biomedical imaging. Participants will receive tsES and participate in follow-up assessments of arm and hand function over a period of 12 months.
