BPPV-CRM

Three Dimensional Simulations of Canalith Repositioning Maneuvers (CRM)

Simulations of canalith repositioning maneuvers (CRM) for treatment of BPPV in the right ear. Animations show debris sedimentation and cupulae volume displacements for long-arm posterior canal (PC), anterior canal (AC) and lateral canal (LC) BPPV and short-arm PC BPPV.  The speed of each animation is accelerated, with actual times shown on the abscissa of the top panel. Acceleration induced cupulae displacements are not shown.   Results use a modified version of the model by  Rajguru SM, Ifediba MA and Rabbitt RD. (2004) Ann Biomed Eng. 32(6):831-46
