Impact of a Paced Breathing Exercise Intervention on Autonomic Nervous System Function After Pediatric Concussion (Acute Phase)

The goal of this pilot clinical trial is to assess the feasibility of administering a paced breathing exercise intervention program to children and adolescents in the acute period after concussion, and to document the autonomic function, and symptom severity (post-concussion symptoms, anxiety, sleep) before and after administration of the intervention. Participants will be instructed to perform a daily 10-minutes daily paced breathing home-exercise program and to document the daily exercises performed within a performance log, or receive usual care from the Pediatric Emergency Department. A weekly phone meeting will be performed with all participants to assess recovery progress. Participants randomized to the intervention group will also be asked about their exercises, will be provided specific instructions and adjustments as necessary. All participants (intervention and control group) will undergo a second assessment after four weeks following completion of the intervention program. During the second assessment, information regarding the intervention feasibility, time to return to school, return to sport, and clear from medication will be collected as well.
