Abstract: Canalith Repositioning Maneuver (CRM) was suggested to be an effective treatment for Benign Paroxysmal Positional Vertigo (BPPV). However, these studies mainly assessed the subjective improvements of patients and involved no control group. The objectives of this study were two folds. Firstly, the profiles of the patients with BPPV were examined; secondly, the effectiveness of the Canalith Repositioning Maneuver in rehabilitation of patients with BPPV with respect to change in the level of positional nystagmus and vertigo, balance function, and daily living function was investigated. Eleven subjects with BPPV were recruited in this study. They were randomly assigned into the control group (n=5) and the treatment group (n=6). CRM was given to the treatment group while sham treatment of Dix-Hallpike maneuver was given to the control group. Vitamin B12 was given to both groups as drug. Dix-Hallpike maneuver, Electronystagmography, Dizziness Handicap Inventory and Dynamic Posturography were measured before treatment, 1-week after treatment, and 1-month after treatment. Friedman two-way analysis of variance by ranks was used for analysis of the treatment effect in each measurement. The within group comparisons were analyzed by Wilcoxon signed-rank test. For all the measurements studied, significant improvement was found in patients received CRM (p<0.05). For the within group analysis, the significant differences were found between the pre-treatment measurements and the 1-week post-treatment measurements and between the pre-treatment and the 1-month post-treatment measurements (p<0.05). In conclusion, the Canalith Repositioning Maneuver is an effective treatment in improving the positional nystagmus and vertigo, daily living function and balance function of the patients with BPPV.
