At-Home Transcutaneous Auricular Neuromodulation for Hypermobile Ehlers Danlos Syndrome

ClinicalTrials.gov · COMPLETED, 2026

25 participants

Abstract

Investigate whether at-home transcutaneous auricular VNS (tAN: transcutaneous auricular neurostimulation) improves a battery of nine key physical and psychological symptoms of a group of hEDS (Hypermobile Ehlers-Danlos Syndrome \& Hypermobile Spectrum Disorder) patients (n=30) using a randomized, double blind, sham controlled design. The study team will collect clinical measures at baseline, after a two-week double-blind intervention phase, after a following two-week open-label phase and finally at three months post intervention. The study team will test patients in the following domains: pain, fatigue, sleep, anxiety, depression, quality of life, GI function, immune function and autonomic function.

Conditions: Hypermobile Ehlers-Danlos Syndrome, Hypermobile Spectrum Disorder, Ehlers-Danlos Syndrome.

Primary outcome: Ehlers-Danlos Syndrome Symptom Battery.

Enrollment: 25 participants.

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 25 participants or records.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
