Intra-rater and test-retest reliability of videography observation method to check diversion time in Fukuda step test among college going students.

Abstract

Purpose: The Fukuda step test is a valuable tool for identifying vestibular dysfunction in humans. This study evaluated the intra-rater and test-retest reliabilities of videograph observations to determine the diversion time while performing the Fukuda test. This study aimed to determine the use of videographic observation as a beneficial tool for recording real-time assessment procedures in clinical settings.

Methods: Fifty college students who were selected based on the inclusion criteria performed three consecutive sessions of the Fukuda step test. Intra-rater and test-retest reliabilities of the videograph observations were identified using the intraclass correlation coefficient (ICC).

Results: We noted both, good intra-rater (ICC= 0.78) and moderate-to-good test-retest reliabilities (ICC= 0.69) of the videograph observations.

Conclusion: Videographic observation can be used in clinical settings to identify diversion times while performing the Fukuda step test.
