If the dizziness is accompanied by visual rotation not exceeding 1min when lying down, the possibility of benign positional vertigo is considered to be high, which is also called otolithiasis. Otolithiasis is position-related, and the diagnosis of otolithiasis can be determined by positional testing when dizziness with intense visual rotation usually lasts no more than 1 min during lying down or turning the head to the left or right. If eye fluttering is seen during the positional test, there is no problem in diagnosing otolithiasis, and it can be treated by manual repositioning. Positional vertigo is a benign vertiginous, peripheral disorder. This disease is painful and may be accompanied by severe nausea and vomiting, but there are no serious adverse consequences, and it can be cured with 1-2 times of manipulation.
