Brief Summary
This research study is being conducted to learn if Transcutaneous Auricular Neurostimulation (tAN®) may be effective in treating alcohol withdrawal syndrome. Transcutaneous Auricular Neurostimulation (tAN®) works by delivering small electrical stimulations to the Vagus and Trigeminal nerves. This study will be conducted over the course of five days. Participants will be enrolled within 24 hours of entering treatment for alcohol withdrawal management. A total of 60 individuals will be enrolled and randomly assigned to either active (treatment with the device + treatment as usual) or sham (treatment as usual) group. Data will be collected on alcohol craving, use of comfort medications, sleep, and mood.

Outcome Measures
Primary Outcomes (2)
Clinical Institute Withdrawal Assessment Scale, Revised (CIWA-Ar) score
Linear mixed effects models for repeated measurements will be used to evaluate the difference in changes in these primary outcomes between treatment and sham group. Mixed models take advantage of multiple measures from each individual, allowing for effects both between individuals and within each individual (e.g., across time). The CIWA-Ar is a 10-item scale measuring symptoms of alcohol withdrawal. The scores can range between 0-67. The total score is the sum of all scale items. Scores between 0-9 indicate absent to minimal withdrawal, Scores 10-19 indicate mild to moderate withdrawal and scores greater than 20 indicate severe withdrawal.
Baseline to end of study day 5
Amount of comfort medications utilized
Medications such as ibuprofen, Librium, lorazepam, promethazine, loperamide, and acetaminophen are often used to treat alcohol withdrawal. A t-test will be utilized to compare medication usage between active and sham group.

Study Arms (2)
Active Transcutaneous Auricular Neurostimulation (tAN)
EXPERIMENTALTranscutaneous auricular stimulation will be delivered using the Sparrow® Link in addition to treatment as usual (TAU). The Sparrow® Link will be set to the following outputs (range 0 mA - 5.0 mA, pulse width 250 µs, frequency 15 Hz at Region 1 (Vagus) and 100 Hz at Region 2 (Trigeminal). Device will be worn for 5 days.
Sham Transcutaneous Auricular Neurostimulation (tAN)
SHAM COMPARATORThe Sparrow® Link will be set to the sham condition for participants in the sham group and no current will be delivered to either the inner or outer ear, but the screen will appear identical to the active group. Sham group will receive treatment as usual. Sham device will be worn for 5 days.
Interventions
Transcutaneous Auricular stimulation will be delivered using the Spark Biomedical Sparrow Link pulse generator with Sparrow Ascent earpieces. The Sparrow Link generator is based on FDA-cleared predicate Sparrow Ascent.
Eligibility Criteria
You may qualify if:
- Ages 18 years old to 65 years old
- Entering an inpatient substance use treatment program for alcohol withdrawal management.
- Score a 27 or higher on the WHO-ASSIST V3.0
- Is proficient in English
- Score of a 4 or higher on the Prediction of Alcohol Withdrawal Severity Scale (PAWSS)
- Able to provide written informed consent.
- Stated willingness to comply with all study procedures and availability for the duration of the study.
You may not qualify if:
- Age \< 18 or \> 65
- Requires medical tapering from benzodiazepines or opioids.
- Has a history of epileptic seizures or seizures due to alcohol withdrawal.
- Has a cardiac pacemaker, cochlear prosthesis, neurostimulator or other device for which tAN® would be contraindicated.
- Has abnormal ear anatomy or an ear infection is present.
- Is pregnant.
- Has any serious medical disease or condition which, in the judgment of the Principal Investigator or his/her designee, would make study participation unsafe, or would make intervention compliance difficult.
