Which ear is affected in Dix-hallpike?
In both tests, for posterior SCC BPPV, the affected side is the typically the “down-side” ear. More important, for both posterior and anterior SCC BPPV, the direction of the torsional component of the nystagmus will always be toward the affected ear in the initial provoking position.
Which side are you testing with Dix-hallpike?
This test is performed by rapidly moving the patient from a sitting position to the supine position with the head turned 45° to the right.

Why does Dix-Hallpike cause nystagmus?
In the provoking Dix-Hallpike position the endolymph pulls on the cupula, because the free-floating otoconia falls under the influence of gravity. In the vertical canals, ampullofugal deflection produces an excitatory response. This would cause an abrupt onset of vertigo and the typical nystagmus described previously.
