The maneuver we can use to assess for horizontal canal BPPV is called the Roll Test. For this maneuver the patient starts sitting up and then they will lay straight back and you will hold their head at a 30 degree angle. Coming back to the center and then the patient can sit up.
What is the head maneuver for vertigo?
The Epley maneuver is designed to put the head at an angle from where gravity can help relieve symptoms. Tilting the head can move the crystals out of the semicircular canals of the ear. This means that they stop displacing fluid, relieving the dizziness and nausea this was causing.
What is the log roll for vertigo?
Log roll exercises for Lateral Canal BPPV. The “log roll” exercises, are a procedure where an individual is rolled in steps of 90 deg, starting supine/affected ear down, to supine, to affected ear up, to nose-down, and then to sitting at intervals of 30 seconds or one minute.
What kind of test do they do for vertigo?
If your doctor suspects your vertigo is caused by benign paroxysmal positional vertigo, he or she may do a simple head movement test called the Dix-Hallpike maneuver to verify the diagnosis. Posturography.
How do I make my head stop vertigo?
Tilt your head around a 45-degree angle away from the side causing your vertigo. Move into the lying position on one side with your nose pointed up. Stay in this position for about 30 seconds or until the vertigo eases off, whichever is longer. Then move back to the seated position.
How do you know which Canal is causing vertigo?

In sitting, patient bows head over 90 degree forward and direction of nystagmus is observed (bowing nystagmus). Patient then leans head backwards over 45 degree and direction of nystagmus is observed (leaning nystagmus).
Can a Horizontal SCC roll test cause nystagmus?
Horizontal SCC: In patients with horizontal SCC BPPV, the Hallpike-Dix Test and side-lying test might not provoke vertigo and nystagmus because the horizontal SCC is not placed in the plane of the pull of gravity. In the roll test, the patient is supine and the head is rolled 90 degrees to the right and left in the plane of the horizontal SCC. 3-5
