Usually used water temperature 20 degrees, causing nystagmus on average in the amount of 50 ml More water required for the emergence of nystagmus, indicates a decrease in excitability of the vestibular apparatus, less on increasing its excitability. Is determined by the duration of nystagmus (usually 1-2 minutes). Cm. also Vestibulometry.
