The inability to move the head and the dizziness when it moves should be considered as a result of two aspects. First, it is considered to be caused by benign paroxysmal positional vertigo, which is commonly known as otolithosis, because the otolith particles in the patient’s balance receptors are dislodged, and when the position of the patient’s head changes, the dislodged otoliths will swim with the endolymphatic fluid. When the position of the patient’s head changes, the dislodged otolith travels with the endolymphatic fluid. This stimulates the cell membrane of the semicircular canal, and the patient exhibits episodes of dizziness with visual rotation. A positional test can be performed to clarify this, and a rotational nystagmus can be observed when the patient has an episode of dizziness. Secondly, dizziness is caused by cervical spine problems when the head cannot be moved, and the patient’s dizziness is aggravated when the head changes and the neck moves. Patients may be accompanied by nausea and sweating, and they dare not open their eyes and lie in bed without moving.
