Supine Head-Hanging Test | 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 ampullofu... | Text |

Supine Roll Test | Supine roll test: used to test for horizontal canal (HC) BPPV. While horizontal nystagmus due to HC-BPPV is often seen with DH, the roll test will usually maximize nystagmus and vertigo with the HC variant. The patient can be guided through a self-administered supine roll test while lying on the flo... | Image/MovingImage |
