Posturographic effects of the Epley maneuver on patients with benign paroxysmal positional vertigo of the posterior

Abstract

Introduction: Benign paroxysmal positional vertigo (BPPV) is the most common periphe- ral condition in otoneurologic diseases. With the repositioning of particles, the aim is to eliminate vertigo and its associated symptoms, such as residual dizziness and instability. Aim: To determine if the Epley repositioning maneuver (ERM) produces a significant mo- dification of postural control (PC) in those patients with posterior semicircular canal BPPV (BPPV-CSC-P). Material and Method: A prospective descriptive study was carried out in a sample of 21 patients diagnosed with BPPV-CSC-P. We compared the displacement, velocity, and area of the center of pressure (CoP) before and after the Epley repositioning maneuver. Results: The velocity and the area of the CoP studied by computed posturogra- phy show a significant decrease in its values after the MRE, while the CoP shift remained unchanged. Conclusion: ERM performed in patients with BPPV-CSC-P produces an im- provement in the control of the CoP, demonstrated by the decrease in the speed and the area of movement of the CoP. The success of the MRE produces modulation of the PC.
