The main manifestation is the vertigo associated with the change of position, which lasts for a short time, usually about a few seconds, and disappears soon after the body position is fixed. In terms of diagnosis, it is recommended to do a displacement test, through which the specific location of the lesioned semicircular canal can be clarified, and after that, targeted manipulation treatment can be carried out. At present, the effect of manipulation treatment is very good, and many patients’ symptoms will disappear soon after manipulation treatment, but a small number of patients with more serious conditions need to be treated with oral medication.
