Abstract:

Introduction Benign Paroxysmal Positional Vertigo is the most common cause of dizziness in elderly people. Recent studies have shown that the elderly present higher Benign Paroxysmal Positional Vertigo recurrence and that vertiginous symptomatology remission varies according to comorbidities and the therapeutic techniques applied.

Objective To assess the short-term effectiveness of Vestibular Rehabilitation in addition to Canalith Repositioning Maneuver on positive to negative Dix-Hallpike test, on recurrence and number of maneuvers to achieve a negative test in elderly patients with chronic Benign Paroxysmal Positional Vertigo.

Methods In this randomized controlled trial, 7 older adults (median age: 69 years, range 65-78) underwent Canalith Repositioning Maneuver and Vestibular Rehabilitation for thirteen weeks. Seven older adults (median age: 73 years, range 65-76) in the control group received only Canalith Repositioning Maneuver. The participants were assessed at baseline (T0), one (T1), five (T5), nine (T9), and thirteen weeks (T13). We assessed the differences between the groups by Mann-Whitney and Fisher exact tests, and used the Friedman and Wilcoxon tests to determine the intragroup differences.

Results No significant differences were found between groups for the positive to negative Dix-Hallpike test, recurrence, and number of maneuvers to achieve a negative test. The number of maneuvers to achieve negative Dix-Hallpike test was lower in intragroup comparisons in the experimental group.

Conclusion The findings suggest that additional Vestibular Rehabilitation did not influence the positive to negative Dix-Hallpike test, recurrence, or number of maneuvers to achieve a negative test in elderly patients with chronic Benign Paroxysmal Positional Vertigo.
