Unilateral Weakness as determined by video-oculography (VOG) versus electro-oculography (EOG) techniques. The R [2] value suggests that 35 % of the variability of the data is explained by the two variables which is less than we expected. We suspect that the variability of the EOG measurements accounts for much of the reduced R [2]. Note that at the accepted threshold for normal UW (<25 %), two normal subjects would have been incorrectly labeled as abnormal whereas none of the VOG measures suggested abnormal results
