Question
What norms are most commonly used in clinics to define hypo- and hyperactive caloric responses?
Answer
Caloric responses are hypoactive if average peak slow phase velocity (peak warm response plus peak cool response divided by 2) is less than 6 deg/sec in both ears. Caloric responses are hyperactive if average peak slow phase velocity (peak warm response plus peak cool response divided by 2) is more than 80 deg/sec in both ears.
