Transcutaneous Auricular Vagus Nerve Stimulation to Improve Upper Extremity Recovery After Traumatic Brain Injury

Upper extremity weakness, impaired coordination, reduced dexterity, and limited arm and hand use may continue after TBI. Repetitive, task-specific rehabilitation may improve function, but recovery can remain incomplete. taVNS is a non-invasive form of electrical stimulation delivered to part of the outer ear. The stimulation is intended to activate nerve pathways involved in learning and brain plasticity while you practice upper extremity tasks. This pilot study will evaluate safety, tolerability, feasibility, and preliminary effects on upper extremity function and cognition. Up to 40 people will take part at Craig Hospital.
