Description |
The supine head-hanging test is more sensitive for AC-BPPV, but it does not differentiate laterality, as both canals are stimulated at the same time [1-3]. When the individual returns to a seated position, the otoconia should hypothetically move closer to the utricle, which continues their ampullofugal movement and leads to a continuation of nystagmus rather than inverting the nystagmus [3]. A test is positive when a patient reports vertigo, dizziness, or sensation of movement or falling with downbeat nystagmus present. The direction of torsion will be towards the affected ear [4]. 1. The patient starts in a seated position. 2. The patient transitions to a supine position with the head extended 30 degrees below the horizon. |
