Modified Canalith Repositioning Maneuver (CRP) technique:
The head was held in each position as follows:
- The subject sat on the long side of the mat table.
- The investigator turned the subject’s head 45 degrees away from the involved side and tilted the patient en bloc into a side-lying position through the coronal plane, with the nose pointing upward.
- Ten seconds after the cessation of vertigo, the subject was tilted nose-down toward the uninvolved side and held there until 10 seconds after the cessation of vertigo.
- Keeping the head turned toward the uninvolved side, the patient was assisted to sit up and remained in that position for 10 seconds after the cessation of vertigo.
- This variation from the original description, eliminating the premedication and shortening the interval between head movements, is associated with significant reductions in vertigo
