Movement disorders are relatively common in the pediatric neurology practice. Describing and
reading about the characteristics of these movements does not substitute the need to observe them in
practice. Once the physician see such movements, recognition becomes easier. All movement disorders are
abnormal and involuntary. Most of them disappear in sleep except palatal myoclonus, which is due to a
lesion in the central tegmental tract. Identifying abnormal movements depends on their characteristics
including whether they are slow or fast, rhythmic or arrhythmic, intermittent or continuous, present at rest or
action, and distributed proximally or distally. In this chapter, important movement disorders will be
discussed depending on the clinical features rather than the specific disease.
