What is the term for involuntary, sustained movements or abnormal postures commonly seen in dystonia?

The correct term for involuntary, sustained movements or abnormal postures commonly seen in dystonia is "dystonic movement." Dystonia is characterized by sustained muscle contractions that can cause twisting and repetitive movements or abnormal postures. The movements are often painful and can affect various parts of the body, making the term "dystonic" specifically applicable to these involuntary muscle contractions and abnormal postures.

While other terms may describe different movement disorders, "dystonic movement" is the precise term that captures the essence of what occurs in individuals with dystonia. Understanding this term is essential for recognizing the clinical manifestations of dystonia and differentiating it from other movement disorders, such as those characterized by ataxia or other types of involuntary movements.
