Material and Methods: Hundred cases of benign paroxysmal positional vertigo (BPPV) were selected on Dix- Hallpike test by non probability convenient sampling technique and randomly divided into two groups of 50 cases each.
All the cases of posterior canal benign paroxysmal positional vertigo, diagnosed by Dix Hallpike test, age between 15 to 65 years of both the gender were included in the study.
All cases of benign paroxysmal positional vertigo diagnosed by Dix Hallpike test.
