- positional test
- fistula test

- rotation test
What is the fistula test?
When you compress the tragus or you use the pneumatic otoscope and it causes vertigo and sometimes nystagmus
How does the caloric test work?
It works with either cold water(30 degrees) or 44 degree(warm water) into the ear canal and stimulates the labyrinth. Nystagmus either occurs towards the ear or away
COWS- cold opposite warm same
