Why the study?

Does sports-related concussion alter arterial pulse wave contours and autonomic nervous system responses in intercollegiate athletes?

Population

17 intercollegiate athletes, mean age ~19-20, predominantly male.

Comparison

Sports-related concussion vs Non-injured control athletes

Design

Cohort

Follow-up

1 week

Implication

May support APW monitoring for post-concussion autonomic dysfunction; hypothesis-generating and requires validation before clinical use.

Structured PICO

Does sports-related concussion alter arterial pulse wave contours and autonomic nervous system responses in intercollegiate athletes?

Population

17 intercollegiate athletes (10 with sports-related concussion within 48 hours, 7 demographically matched non-injured controls), mean age ~19-20, predominantly male.

Intervention

Sports-related concussion (evaluated at rest and during the first 60 seconds of an isometric handgrip test at 30% of maximal voluntary contraction)

Comparator

Non-injured control athletes (evaluated at rest and during the first 60 seconds of an isometric handgrip test)

Outcome

Changes in arterial pulse wave (APW) contours (SysSlope, reflection index, stiffness index, and dicrotic notch characteristics) at rest and during the first 60 seconds of an isometric handgrip test at 48 hours and 1 week post-injurysurrogate

Concussed athletes exhibit transient increases in peripheral artery stiffness and paradoxical declines in stroke volume surrogates during metabolic demand, suggesting cardiovascular autonomic dysfunction.
