ABSTRACT
PURPOSE: To explore possible associations between cervical spine mobility, measured by cervical range of motion (CROM) and a possible earlier onset of recurrent benign paroxysmal positional vertigo (BPPV), as well as an increased failure rate of canalith repositioning procedures.
METHODS: Medical records of 749 patients (247, 253 and 249 patients with a CROM ≤ 45°, between 45.1° and 55° and > 55.1°, respectively) with a first-time diagnosis of non-traumatic BPPV were included in this retrospective study. Age, gender, canal involvement and CROM values were treated as prospective prognostic factors for time of BPPV recurrence onset (RO) and number of manoeuvres needed to achieve resolution (resolution rate, RR). A multiple regression analysis was performed.
RESULTS: A significant increase in the incidence of recur rent BPPV was found in patients with reduced CROM (139 [56.27%;], 102 [40.31%] and 87 [34.93%], respectively, belonging to ≤ 45°, 45.1°-55° and > 55.1° subgroups; X2 = 9.42, p = 0.008). A strong association between age, CROM and recurrent BPPV RO and RR was demonstrated, respectively (multiple correlation coefficients = 0.492678 and 0.593493, respectively, p value < 10-4). Canal involvement was in line with the previous experiences.
CONCLUSION: The results from this retrospective analysis unveiled the previously unexplored relation between reduction in cervical spine mobility and BPPV recurrence and treatment failure. The data from this study do not indicate the mechanisms by which this comorbidity might directly cause recurrent BPPV. However, they may suggest CROM to be evaluated, in association with other known risk factors for increased susceptibility to BPPV recurrence.
