@alexlewis I’ve actually never heard of this and I’ve seen a lot of BPPV on placement! From reading online it seems like this might actually be a therapeutic test for horizontal-BPPV rather than diagnostic though? Perhaps we can clarify that in the question?
@Stapedius I’ve had a better look and I think you’re right. It looks like dix hallpike diagnoses anterior and posterior canal, and generally is the only test that gets done because posterior canal is so common. This card is wrong, and bbq roll is the treatment for lateral canal, and supine head roll (Supine Head Roll Test | Lateral Canal BPPV Assessment) is the diagnostic test.
So should change the card to supine head roll test.
