Heart Rate Variability Biofeedback for Anxiety in Autistic Youth
Source: ClinicalTrials.gov · Last updated 16 Oct 2026
Brief summary (registry, in English)
Heart rate variability biofeedback (HRVB) is a breathing-based intervention that reduces anxiety in a range of populations. Second-generation wearable HRVB devices not only deliver scheduled biofeedback practice sessions but also allow patients to practice HRVB in-the-moment when it is needed most. This study is testing the acceptability, feasibility, and preliminary efficacy of second-generation, ambulatory HRVB for the treatment of anxiety in autistic youth.
