In 48 patients with Meniere's disease, caloric testing was done with 2ml of ice water and 50ml of hot water at 44°C for 20 sec. The simplified method measures the duration of caloric response. With electro nystagmography the maximum velocity of the slow component can be determined.A statistical comparison showed that the latter test is significantly more sensitive than the former.
