incredible video. doc, I have a question, is it normal to have little saccades when performing slow vor (moving head slowly left and right) looking to small targets far away?

Dear sir - For me it is very difficult to avoid double movements when doing Head impulse test. Can I do it with patient in supine position? It is much easier to maintain the speed and to avoid double movement. Your comment please.

Dear Doctor- Why in Dix hallpike test Nystagmus beats towards the affected ear and in Hints test Nystagmus beats away from the affected ear?

Different pathophysiology, otoliths moving fluid, vs dysfunction of a nerve. Beyond that, it gets complicated to explain. Maybe I'll make a video about it.

@@PeterJohns Dear Sir, Could the the nystagmus in BPPV ( towards the affected side) and in vestibular neuritis ( opposite to the affected ear) be due to the fact that in BPPV the nerve is excited and impulses are more than the normal and in vestibular neuritis the nerve is depressed and impulses are less than normal?

You mean they get dizzy during the Dix-Hallpike test? Look up subjective BPPV. Some people think that it is common, but I think it is rare.

So 2 normals is abnormal but a unilateral abnormal is a vestibular neuritis?

Yes, as long as you understand that this is only done on patients with AVS (acute vestibular syndrome) and they should have spontaneous or gaze evoked nystagmus. And that seeing a normal HIT on both sides is worrisome for a posterior circulation stroke. The reason being is that the HIT is testing the vestibular ocular reflex, and it does not involve the cerebellum.
