One maneuver we can use to diagnose left posterior canal
BPPV is the left Dix-Hallpike. To do
this maneuver you have your patient look over their shoulder and lie straight
back, the whole time looking at your patients eyes, looking for up beating
nystagmus with left torsion. You would
stay here for 30 seconds until or until you see nystagmus and that nystagmus
has fatigued. Then we sit up and looking
at the eyes for any nystagmus as they sit up.
