Introduction And Objective:
Benign paroxysmal positioning vertigo is considered the most common disorder of the peripheral vestibular system. After successful physical manoeuvres for BPPV, a number of patients complain of non-positional sustained imbalance of variable duration called residual dizziness lasting for several days. The objective of this study was to compare the posturographic changes before and one week after successful repositioning manoeuvres in patients with idiopathic BPPV.
Materials And Methods:
This study was a case-control study, where the first group was composed of 20 patients with confirmed BPPV diagnosis regardless of the affected canal or pathology. Twenty age and gender matched normal subjects constituted the control group. The sensory organization test was performed before and one week after a repositioning manoeuvre in BPPV patients.
Results:
All 20 BPPV patients, except 6 who had no significant improvement of symptoms even after disappearance of classic vertigo and nystagmus, had substantial improvement in sensory scores after CRPs in the antero-posterior visual and vestibular scores and the medio-lateral visual and global scores. All antero-posterior and medio-lateral scores before and after CRPs, except for the AP preferential score, were considerably poorer in BPPV patients than healthy subjects. The 6 patients, who showed no improvement after CRPs, presented with a history of non-specific symptoms i.e., light-headedness or sense of floating.
Conclusions:
Sensory organization test might have a role in the assessment of residual dizziness in patients with BPPV after CRPs.
