Hi,
Thank you for posting your query.
the technique you are referring to is- Dix-Hallpike's maneuver. However, as you mentioned, it should be done by trained medical personnel, as if not done properly, it can aggravate the symptoms of
dizziness and patient would take a long time to recover.

I hope it helps.
Please get back if you require any additional information.
Best wishes,
