Introduction
Patients with benign paroxysmal positional vertigo (BPPV), especially the elderly,
often experience a greater incidence of falls and postural instability. The Epley
repositioning maneuver has been proven to be effective in improving the postural
control, whereas Gans repositioning maneuver (GRM) is still lacking data.
Objective
The objective of this study was to compare between the effectiveness of GRM and
Epley repositioning maneuver in improving postural stability in elderly patients with
posterior canal BPPV.
Patients and methods
In this randomized controlled trial, patients were randomly assigned into two
groups. Group A (study group) was assessed by side-lying test and treated by
GRM, whereas group B (control group) was evaluated by Dix–Hallpike test and
treated by the Epley repositioning maneuver. Postural stability was estimated by
computerized dynamic posturography.
Results
Patients in both groups showed improvement within the groups in equilibrium
scores subtest 4, 5, 6 (P<0.05), whereas there was no significant difference
between groups (P>0.05) regarding equilibrium scores.
Conclusion
GRM is as effective as the Epley repositioning maneuver in improving postural
stability in elderly patients with posterior canal BPPV.
