Description
Head-shaking nystagmus: With a peripheral lesion, similar to vibration, transiently accentuates vestibular asymmetry when baseline VOR function is asymmetric, central patterns are well described and have localizing value (e.g., causing vertical nystagmus after horizontal head-shaking, horizontal nystagmus in the opposite direction to a spontaneous nystagmus, or an early and strong reversal of the nystagmus) Instructional ocular motor examination procedures.
