Summary

The goal of this single-blinded randomized, controlled trial is to assess the impact of 1-hour of active transcutaneous auricular vagus nerve stimulation (taVNS) vs sham taVNS on serum biomarkers of the inflammatory reflex and inflammation in individuals with spinal cord injury.

The main question it aims to answer is: whether taVNS is a safe and effective anti-inflammatory intervention for individuals with SCI. Participants will perform a single 1-hour bout of the respective taVNS treatment with blood draws prior to treatment, immediately following treatment, and 24 hours following treatment. Changes in biomarkers between the active and sham taVNS conditions will be compared.

DEVICE

Transcutaneous auricular vagus nerve stimulation

Stimulation will target the auricular branch of the vagus nerve by applying stimulation to the cymba conchae region of the ear using the NEMOS® taVNS device (taVNS Technologies, Erlangen, Germany). To achieve adequate stimulation while avoiding unpleasant or painful sensations, the stimulation intensity will be gradually increased in increments of 0.1mA until the subjective pain threshold is reached, and then reduced to a stimulus intensity just below the individuals pain threshold (expected range based on prior studies 1 - 3.2mA(3). Pulse width will be set at 100μs and frequency will be set at 25Hz as performed in a previous protocol in stroke patients(3). The control group will receive the same stimulation parameters but will have the earpiece placed in the sham position such that stimulation is applied to the earlobe and does not activate the vagus nerve(4).
