Hybrid maneuver for benign paroxysmal positional vertigo in individuals with limited neck mobility: Case series.

ABSTRACT

INTRODUCTION: Mobility limitation of the cervical spine compromises the adequate execution of the canalith repositioning maneuver (CRM) in cases of posterior semicircular canal benign paroxysmal positional vertigo (PSC-BPPV-GEO). Thus, novel therapeutic options are required for such individuals. OBJECTIVES: This study describes the effects of a change in the biomechanical position for the execution of the CRM on symptoms of dizziness and mobility limitation regarding flexion-extension of the cervical spine in older people with unilateral PSC-BPPV-GEO. METHODS: A quasi-experimental viability study was conducted with 15 older adults (11 women; mean age 72.2 ± 8.1 years). Treatment consisted of a hybrid CRM. The participants were evaluated before and after the intervention using the modified Dix & Hallpike test, Dizziness Handicap Inventory (DHI) and a visual analog scale (VAS) for vertigo. RESULTS: The modified Dix & Hallpike test was negative in all cases after the execution of the hybrid CRM. A significant reduction was found for dizziness measured using the DHI (mean difference -39.3 ± 9.4, p < 0.001) and VAS (mean difference -2.9 ± 0.8, p = 0.04) after the intervention. CONCLUSION: The hybrid CRM proved executable and satisfactory for resolving symptoms of dizziness in older adults with PSC-BPPV. The present findings are promising and randomized controlled clinical trials should be conducted to evaluate the effectiveness of the hybrid CRM in this population.
