Why the study?
Recent systematic reviews show conflicting data on the effect of concussion on cardiac autonomic function, leaving a gap regarding the utility of objective metrics during exertional rehabilitation and return-to-play protocols.
Can heart rate variability (HRV) during physical exertion be a reliable biomarker over time for those who suffered a sport-related concussion?
Can heart rate variability (HRV) during physical exertion be a reliable biomarker over time for those who suffered a sport-related concussion?
Exertional heart rate variability shows promise as an individualized biomarker for assessing autonomic function recovery following sport-related concussions.
Emerging support for HRV as exertion biomarker in concussion recovery; leaves open prospective validation before clinical adoption.
