Abstract

Objective: To assess the long-term stability of caloric testing in patients.

Methods: In this retrospective study, Cronbach's alpha was used to determine whether caloric testing results are stable over time (up to 7 years) in patients who have not undergone interventions. After excluding invalid records, two hundred patients who underwent repeated caloric testing in the same lab over varying periods of time were included.

Results: Cronbach's alpha scores were 0.512 for unilateral weakness and 0.051 for the sum of caloric tests indicating that the stability of caloric tests is poor over long terms.

Conclusion: The stability of caloric testing with repeated testing over long terms is not reliable.
