Again, keep the patient in this position for about 30 seconds. Then quickly move the patient back up with the same head position and through the sitting position so that he is in the opposite-lying position with the head facing down. Keep the patient in this position until at least 20 seconds after all nystagmus has ceased. A nystagmus will occur shortly after arriving at the side-lying position and the patient will probably experience vertigo. Then quickly bring the patient into side-lying position toward the affected side with the head turned up. To perform the Semont maneuver have your patient sit in the middle of the treatment bench with the head turned away from the affected right side. On top of that, make sure that your patient is able to tolerate neck movement. The patient should be counseled that his symptoms of vertigo will be reproduced and that he might feel nausea. ![]() So make sure you have a bucket at hand, in case your patient might need it. Be aware that the Epley maneuver can lead to nausea which was reported in 17-32% of patients. The chance of success in this review was described to be as high as 85%. There was no difference when Semont was compared to with the Epley maneuver that you can watch by a click in the top right corner. found that the Semont maneuver was more effective than sham maneuvers or control. In a Cochrane review from 2014, Hilton et al. The Semont liberatory maneuver involves a series of movements of the head and body in order to move the debris out of the posterior semicircular canal. This causes movement of the cupula and bending of the hairs of the hair cells, and provokes vertigo.Īround 20% of BPPV cases are said to resolve within 4 weeks and up to 50% up to 3 months without treatment, but recurrence is reported between 10-18% after 1 year. In canalithiasis, free-floating debris in the semicircular canal is hypothesized to act like a plunger, causing continuing movement of the endolymph even after head movement has ceased. The cause of BPPV is believed to be canalithiasis, affecting the posterior semicircular canal in 85 to 95% of all cases. Head rotation causes relative movement of the endolymph in the semicircular canal, which bends the cupula and the embedded hairs of the hair cells and causes stimulation of the relevant vestibular nerve. The main sense organ in each canal is called the crista, which is stimulated by movement of the cupula. The semicircular canals are filled with a fluid called endolymph. This causes ongoing movement that conflicts with other sensory information. BPPV can be caused by debris in the semicircular canal of the ear, which continues to move after the head has stopped moving. Common causes are head trauma or ear infections, although most cases appear to be idiopathic.
