Heart Rate Variability Biofeedback for Anxiety in Autistic Youth
Sponsor: Massachusetts General Hospital
Summary
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.

Lief Smart Patch
The Lief Smart Patch is a commercially available, noninvasive wearable heart rate variability biofeedback (HRVB) device. The patch includes an embedded electrocardiogram (ECG) sensor and accelerometer that interfaces with a companion smartphone application to deliver paced breathing exercises and just-in-time adaptive intervention (JITAI) prompts. It is an externally worn patch that temporarily adheres to the skin surface and can be removed by the participant.
