Dystonia - Definition

June 2017


Definition


Dystonia refers to a neurological motor disorder responsible for abnormal muscle tone. It appears in the form of prolonged, involuntary muscle contractions leading to abnormal postures. The body, or body part, can contract abnormally during movement and adopt a position that is unnatural. When the symptoms are observed, repeated contractions usually affect the same muscles and postures are identical. This symptom may occur in the absence of an identified disease or follow a neurological event such as a stroke.
