Why the study?
Autonomic nervous system dysregulation may contribute to persistent post-concussive symptoms, but post-injury breathing dysfunction influenced by the autonomic nervous system has not been well-studied in youth.
Do youth with persistent post-concussion symptoms have altered cardiorespiratory functioning compared to non-injured controls?
Population
25 youth aged 13–25 years, including 13 patients with PPCS and 12 non-injured controls
Comparison
Youth with PPCS vs non-injured controls
Design
Pilot study

May inform ANS assessment in youth PPCS; leaves open causal links to outcomes in larger trials.
Do youth with persistent post-concussion symptoms have altered cardiorespiratory functioning compared to non-injured controls?
Youth with persistent post-concussion symptoms exhibit altered breathing dynamics, specifically reduced end-tidal CO2, which correlates with poorer neurobehavioral outcomes.
Snyder et al. (2021) studied this question.
