Improving Speech in Noise Using Noninvasive Stimulation
Recruiting now · Not applicable
Conditions studied: Traumatic Brain Injury, Hearing Loss
In brief
Traumatic brain injury, a common injury in military service personnel, often leads to poor processing of speech in noisy environments. The goal of the current study is to better understand the brain basis for this difficulty and evaluate a new approach to improving speech in noise perception.

- Other neurological diseases or related conditions will be excluded (e.g., large vessel stroke, seizures). We will exclude patients with severe medical diseases that may be associated with impaired cognition (e.g., heart failure, dialysis dependent kidney disease, brain cancer). Further, psychiatric diseases that are unlikely to be related to trauma will be excluded (e.g., schizophrenia).
- Patients with histories of severe psychiatric disease prior to trauma exposure will be excluded.
- Current illicit or prescription drug abuse (within the last two months)
- Any taVNS contraindication, including but not limited to the presence of unremovable metal in the left ear, known heart conditions, medications that influence neurotransmitters thought to be critical for vagus nerve stimulation (norepinephrine, acetylcholine, and serotonin), or implanted medical devices such as a pacemaker.
