May indicate acute autonomic dysregulation after concussion; hypothesis-generating, needs prospective validation before clinical use.
Does sport concussion alter parasympathetic baroreflexes and heart rate variability during the acute stage of recovery compared to healthy controls?
Autonomic function, specifically heart rate variability, appears dysregulated within the initial 72 hours following a mild traumatic brain injury.
