Modified clinical test of sensory interaction on balance test use for assessing effectiveness of Epley maneuver in benign paroxysmal positional vertigo patients rehabilitation

Benign paroxysmal positional vertigo (BPPV) is most common type of vertigo in general population. Epley maneuver is the most effective treatment technique. However, there is no clinically valid test to verify effectiveness of maneuver quickly after treatment in the same session. Modified clinical test of sensory interaction on balance (mCTSIB) is considered as a quick and simple test. This study aimed to use mCTSIB for assessing effectiveness of Epley maneuver in BPPV patients.
The study was carried out on 44 patients (36 female and 8 male, mean age of 53.11 (SD=7.09) diagnosed with posterior semicircular canals BPPV in Dix-Hallpike test and no other vestibular disorders. mCTSIB in four conditions was assessed, before and after Epley maneuver. Balance time, lateral and anterior-posterior sway were recorded. mCTSIB repeated after three weeks to assess reliability.
The time for balance control in mCTSIB after maneuver did not change significantly relative to before maneuver (p>0.05). Lateral sway changes in conditions 2, 3 and 4 in mCTSIB significantly reduced after maneuver (p=0.04). Anterior-posterior sway changes in conditions 1 and 2 showed no significant difference after maneuver, however, differences in conditions 3 and 4 were statistically significant (p mCTSIB is seems be a valid test with simple and quick apply for verifying the effectiveness of Epley maneuver in BPPV patients.
