Initial investigation of kinesiophobia as a predictor of functional reaction time one year after concussion

Abstract

Aim: The relationship between post-concussion kinesiophobia and clinical and functional reaction time (RT) beyond clinical recovery remains to be elucidated. Methods: College-aged participants with (n = 20) and without (n = 20) a concussion history completed patient-reported outcomes, and RT tasks. Kinesiophobia, symptoms and RTs were compared using t-tests. Linear regressions were performed to determine if kinesiophobia predicted RT measures and dual-task cost. Results: The concussion history group reported higher scores (p 0.05). Kinesiophobia significantly predicted single-task RT (R2 = 0.22). Discussion: Kinesiophobia should be considered when measuring RT.
