Vestibular tests.
The results of vestibular tests for athletes with sports-related concussion (SRC) and controls. The results for the specific tests video head impulse test (vHIT), caloric test, cervical evoked myogenic potentials (cVEMP), videonystagmography (VNG), posturography, and pursuit eye movements (PEM) are reported as number and percent with pathological findings. The results of vHIT and cVEMP differ significantly between athletes with SRC and controls. The significance threshold was set to 0.05; significant values are bolded.
