Which Canalith Repositioning Maneuver is done depends
upon the canal the otoconia are in. The way we determine where the rocks are loose is by watching the eyes when performing a variety of tests. We have been trained to identify and name the nystagmus that occurs. Depending upon the direction of the nystagmus and how long the nystagmus lasts will guide us in determining the most appropriate repositioning maneuver to perform.
