Official title

Enhancing Cognitive Rehabilitation After TBI Using Noninvasive Vagal Nerve Stimulation

Overview

The purpose of this study is to examine the feasibility and preliminary efficacy of using transcutaneous auricular vagus nerve stimulation (tVNS) to enhance cognitive recovery in patients with mild-moderate traumatic brain injury (TBI).

Detailed description

Eligible participants will be invited to two sessions, 2-7 days apart. In each session, either active tVNS or sham stimulation will be administered while the participants are performing tasks of executive functions. The order of the sessions (tVNS vs Sham) will be counterbalanced across participants.

Interventions

  • Device Transcutaneous auricular vagus active nerve stimulation
    In the active stimulation, two electrodes are placed in the cymba conchae of one of the ears, an area thought to be exclusively innervated by the auricular branch of the vagus nerve.
  • Device Transcutaneous auricular vagus sham nerve stimulation
    In the sham stimulation, the electrodes are placed on the tail of helix, which is free of vagal innervation.

Primary outcome measures

  • N-Back Computerized Task [Time frame: 15 minutes]
  • Trail Making Test - Parts A & B [Time frame: 5 minutes]
