Results for controls are means and p values for the comparison with the case group.
*Ice water test was not performed in the control group as it provokes a severe vertigo in patients with no vestibulopathy.
B, bilateral; C, closed eyes; F, fall; I, instability; IW, ice water, Caloric, galvanic and vibratory tests: expressed in degrees per second; L, left; N, normal; NP, not performed; O, open eyes; R, right; RS, refixation saccades; vHIT, video head impulse test.
