The nystagmus responses of two groups of patients referred for electronystagmography were compared to test for differences between air and water caloric stimulation. Responses from patients with spontaneous or positional nystagmus or who showed greater than 30% directional preponderance or excitability of labyrinth were removed from the data. The 30% C and 44% C water and the 24% C air produced equivalent responses. The 50% C air produced responses with slow component velocities greater than expected; however, the distributions of computed directional preponderance and excitability of labyrinth showed no differences between the air and water caloric stimulation.
