The Factors Influencing the Accuracy of Head Position During Canalith Reposition Procedure Using 9 Axis Inertial Sensor

Background and Objectives The canalith reposition procedure (CRP) is used for the treatment of benign paroxysmal positional vertigo (BPPV) where the accuracy of position may affect the therapeutic efficacy. We investigate the accuracy of head position in CRP and its influencing factors during the procedure by measuring the position using inertial sensors and three dimensional remodeling.Subjects and Method We included 28 patients who were...
