App-based Breathing Program for Migraine Relief

This study is a randomized controlled trial aimed at examining the effect of Heart Rate Variability Biofeedback (HRVB) among people with chronic migraine. The primary objective of the study is to determine whether HRVB can positively impact the psychosocial health and well-being of those living with chronic migraines. Building upon our prior pilot RCT (IRB study ID: STUDY00018977; ClinicalTrials.gov ID: NCT06546163), which demonstrated the feasibility and acceptability of HRVB in college-aged women with disordered eating, investigators propose to examine the feasibility of a HRVB intervention using the device investigators have successfully implemented remotely, incorporating video guides and Zoom-based coaching for smartphone app set-up and use. Investigators will conduct a remotely delivered pilot RCT of an 8-week, 10 min/day, novel app-based HRVB intervention compared to a sham control intervention (matching intervention time and attention with no biofeedback component) in adult with chronic migraines. There will be 30 participants who experience chronic migraines that will participate in the study and they will be randomly assigned to either the HRVB intervention group or the control group (15 for each group). Participants will first attend a baseline orientation meeting during which they complete baseline measures and will be asked to complete 28 days of a 5-10 minute daily diary survey about their migraine-related experiences. After the 28 days, participants will attend a zoom training meeting during which they complete a 5-minute heart rate measurement using a small earlobe sensor device that investigators will mail to participants , will be randomly assigned to the HRVB group or sham control group, and be asked to complete the daily diary assessments for another 28 days. After 8 weeks since the baseline and 4 weeks since group assignment, participants will attend a final zoom meeting to complete follow-up measures and the heart rate measurement. Investigators hypothesize data collected from the study will: a) support the feasibility and acceptability of the remotely delivered app-based HRVB intervention among adults with chronic migraines, and b) provide insights into refining the intervention by examining patterns of change in migraine and psychological outcomes from pre- to post-intervention.
