Term info
Head titubation
Titubation often accompanies midline cerebellar lesions. The 3-4 per second frequency of titubation is faster than the head nodding/bobbing that can be seen with thalamic lesions. The original description of head titubation in 1899 by Gowers (see PMID:4821687) was: As the disease progresses, some jerky irregularity develops in the movement of the neck and head so that the head presents slight movements, sometimes like an irregular tremor, sometimes simulating chorea.
