Background and Objectives The canalith reposition procedure (CRP) is used for the treatmentof benign paroxysmal positional vertigo (BPPV) where the accuracy of position may affectthe therapeutic efficacy. We investigate the accuracy of head position in CRP and its influencingfactors during the procedure by measuring the position using inertial sensors and three dimensionalremodeling.
Subjects and Method We included 28 patients who were diagnosed as BPPV. To evaluatethe accuracy of the CRP, we used the inertial sensor on the patient’s goggle used for videonystagmography.
We evaluated the accuracy of the treatment compared to the textual treatmentused during CRP. We also evaluated patient factors that affected the accuracy of head positionas well as analyzing the correlation between the error rate and the successful treatment rate.
Results While the average error rate was 12.6±5.8% for the PSCC group, it was 10.2±5.2%for the lateral semicircular canal (LSCC) group. For the posterior semicircular canal (PSCC)the group with body mass index (BMI), less than 25 patients had the lower error rate than thegroup with BMI greater than 25. There was no significant differences regarding the error rateaccording to BMI or age in the PSCC group. There is no significant differences regarding theerror rate between those treated within 1 week and those over 1 week. For the LSCC delayedtreatment group, there was no significant differences of error rate between the 1st and 2nd maneuverat each position.
Conclusion For the Epley maneuver, the error rate of patients with high BMI is higher thanthose with low BMI. When the repeated barbeque maneuver was conducted, patients could havea more accurate position due to the learning effect. Care should be taken to ensure accurate CRPby considering various factors.
