Dyskinesia
Pronunciation: dis-ki-NEE-see-ah
Involuntary, abnormal movements that can interfere with voluntary motor control and functional activities.
Full Definition
Dyskinesia refers to a group of involuntary movement disorders characterized by abnormal, uncontrolled movements that can affect various parts of the body. These movements may be choreiform (dance-like), dystonic (sustained muscle contractions), or athetoid (slow, writhing movements). Dyskinesia can result from neurological conditions, medication side effects (particularly from long-term dopaminergic therapy), or brain injury. In rehabilitation settings, dyskinesia presents significant challenges for functional training and may require medication adjustments, environmental modifications, and specialized therapeutic approaches to optimize patient safety and functional outcomes.
Usage
Usage note: Specify type when possible (tardive, medication-induced, etc.); often requires interdisciplinary management.
