Postural control in benign paroxysmal positional vertigo before and after recovery

Area of Science:

• Neurology
• Vestibular System Disorders
• Biomechanics

Background:

• Idiopathic benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo.
• BPPV affects the posterior semicircular canal, impacting vestibular function.
• Postural control is crucial for maintaining balance and preventing falls.

Purpose of the Study:

• To investigate postural control in patients with BPPV before and after the Semont maneuver.
• To assess the long-term effects of BPPV on vestibular compensation and balance.
• To determine if residual vestibular deficits impact postural stability post-treatment.

Main Methods:

• Dynamic posturography was used to evaluate postural control in 32 BPPV patients.
• Patients were tested before, 3 days after, and 1 month after the Semont maneuver.
• The Sensory Organization Test (SOT) was employed to analyze equilibrium scores and vestibular involvement.

Main Results:

• BPPV patients exhibited impaired overall postural control with pathological equilibrium scores.
• The Semont maneuver significantly improved composite and vestibular scores.
• Despite clinical recovery, significant differences in postural control persisted compared to controls at 3 days and 1 month post-maneuver.

Conclusions:

• BPPV leads to vestibular system impairment affecting postural balance.
• Dynamic posturography effectively detects vestibular-related balance deficits.
• Residual postural control differences suggest otoconial maculae damage influences balance even after symptom resolution.
