Paced breathing to improve autonomic function after pediatric concussion

Impact of a Paced Breathing Exercise Intervention on Autonomic Nervous System Function and Symptom Severity in Youth Post-concussion: a Pilot Feasibility Study

Not applicable Interventional McGill University Health Centre/Research Institute of the McGill University Health Centre · NCT07572734

This project tests whether a daily 10-minute paced breathing exercise started within 72 hours of injury can help children and teens (ages 9–18) recover faster and reduce autonomic-related symptoms after concussion.

What this trial studies

This randomized pilot compares a home-based, daily 10-minute paced breathing program to usual care for children and adolescents who present to the emergency department within 0–72 hours after concussion. Participants aged 9–18 perform the breathing exercise each day, record sessions in a log, and receive weekly phone check-ins to monitor recovery and adjust instructions as needed. The primary aim is to determine feasibility of administering the intervention in the acute post-injury period, with secondary measures including autonomic-related symptom severity, overall post-concussion symptoms, anxiety, sleep, and time to symptom improvement. The trial is conducted at the Montreal Children's Hospital under the McGill University Health Centre.

Who should consider this trial

Good fit: Children and adolescents aged 9–18 who present to the emergency department within 0–72 hours after concussion and report at least one autonomic-related post-concussion symptom are ideal candidates.

Not a fit: Patients with known heart disease, prior neurological disorders other than concussion, those presenting more than 72 hours after injury, or those without autonomic-type symptoms are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, this simple, low-risk breathing program could speed recovery and reduce autonomic and post-concussion symptoms in children and adolescents.

How similar studies have performed: Breathing and heart-rate variability interventions have shown benefits for anxiety and autonomic regulation in other populations, but evidence specifically for early pediatric concussion is limited to small or pilot studies.
