This study is designed as a pilot, single-center, non-randomized, uncontrolled, clinical trial in which subjects will be consented, receive a baseline assessment, and receive tAN treatment and assessment every day during their 3 to 5-day detox treatment. Use of opioid-based medication assisted therapy (MAT) will not be permitted at any point during the study. Use of non-opioid-based MATs (i.e. comfort or rescue medications) will not be permitted until after the subject has completed the 60 minute COWS assessment to ensure changes in COWS score at 60 minutes are only the result of tAN therapy.
The objective of this study is to evaluate whether tAN via the tragus (vagal) and auriculotemporal (trigeminal) nerve pathways results in a clinically meaningful reduction in opioid withdrawal symptoms.
