B-105: Autonomic Reactivity in Concussed Adolescents: Heart Rate Variability Changes From Baseline to Post-Stress Recovery
Objective: Autonomic nervous system (ANS) dysfunction may mediate concussion recovery. Using heart rate variability (HRV) as an index of ANS responses to stress, we examined autonomic recovery to cognitive and physical stressors in adolescents with post-acute concussion. We also explored the relationship of working m...
