Demi Semont Maneuver for apogeotropic left PSC-BPPV (Non-ampullary arm canalolithiasis)

The patient is seated in front of the examiner having the legs hanging down the examination table. The patient’s head is turned by 45° to the right (healthy) side in the yaw plane, to put the left PSC onto the coronal plane. Thereupon the patient is brought onto the right (healthy) side. It is better to move the subject not too briskly, in order to avoid an excessive ampullopetal endolymphatic flow that would push the debris towards the ampullary arm of the canal, but using a final sharp deceleration to the head in order to take advantage of the inertia of otoconia and move it towards the common crus, so that it can enter the utricle.
