Supine Roll Test

The primary purpose of the Supine Roll Test is to diagnose horizontal canal benign paroxysmal positional vertigo by identifying the presence and type of nystagmus when the patient's head is turned to the side.

A positive result is indicated by the presence of nystagmus and vertigo during the test. Geotropic nystagmus suggests free-floating otoconia in the horizontal canal, while apogeotropic nystagmus indicates otoconia adhering to the canal wall.

The Supine Roll Test is generally safe, but some patients may experience temporary discomfort or dizziness during the procedure. To ensure safety and accuracy, the test should be conducted by a trained healthcare professional.
