[From the expert opinion case book: cervical nystagmus following injury of the occipital joint].

A case submitted for expertising is presented. After a fall on the occiput with a fracture of the occipital bone the patient had a pathological cervical nystagmus (type II according to Moser). The subjective complaints grew better in course of months. It is attempted to interpret the cause of the persistent proprioceptive cervical nystagmus. The disappearance of cervical vertigo is explained as being due to habituation.
