Targeted Plasticity Therapy for Upper Limb Rehabilitation in Spinal Cord Injuries

Stimulation of the vagus nerve that is paired with upper extremity rehabilitation. VNS stimulation as described in the current study consists of 0.5 s trains of 0.8 mA 100 µs biphasic pulses delivered at 30 Hz. Stimulation trains are delivered only during rehabilitation.

During Phase 1 of the study, the placebo group will receive a minimal amount of stimulation that fails to sufficiently activate the nerve, unknown to the participant and therapists. All participants will receive active stimulation during the Phase 2 open-label portion of the study.
