ABSTRACT INTRODUCTION: Benign paroxysmal postural vertigo originating from the peripheral vestibular system is characterized by brief vertigo spells triggered by the sudden head motion. Usually, vestibular dysfunction in benign paroxysmal postural vertigo is unilateral. Fukuda stepping test which is helpful in the diagnosis of unilateral vestibular dysfunction, may also be valuable in the prediction of prognosis of benign paroxysmal postural vertigo. OBJECTIVE: The purpose of this study is to evaluate the relevance of Fukuda stepping test results with resistant and/or recurrent benign paroxysmal postural vertigo cases. METHODS: We evaluated 62 patients with unilateral, idiopathic benign paroxysmal postural vertigo of posterior and/or lateral canals. The Fukuda stepping test was performed prior to the Dix-Hallp ike and head-roll tests. Two groups were created according to the Fukuda stepping test results. In Group 1 Fukuda stepping test results were positive with a deviation angle >45°, while in Group 2 the results were negative with no apparent deviation. Two groups were compared by the number of canalith repositioning manuevers performed and the frequency of recurrences. RESULTS: We found Fukuda stepping test to be invaluable in the diagnosis of benign paroxysmal postural vertigo since the ratio of Fukuda stepping test positivity and negativity were similar in benign paroxysmal postural vertigo patients. However, the need for multiple canalith repositioning manuevers was significantly higher in Group 1 (p = 0.0103). In addition, the recurrence frequency was found significantly lower in the Group 2 (p = 0.0441). CONCLUSION: Although the sensitivity of Fukuda stepping test in detecting mild/moderate unilateral vestibular dysfunction is poor, it may be valuable in prediction of the prognosis of benign paroxysmal postural vertigo. We suggest that positive Fukuda stepping test results in benign paroxysmal postural vertigo patients indicate poor prognosis, the need for multipl canalith repositioning manuevers and the higher possibility of recurrences.
