R and P of regression fitting curve between the variable self-motion perception (SMP), caloric test (CP, canal paresis; DP, directional preponderance), head shaking test (HST), and subjective visual vertical (SVV) at 1 wk and 4, 8, and 12 mo after acute episode of with unilateral vestibular lesions (UVL) in 30 patients.
