Dystonia is a medical term that refers to involuntary movements and prolonged muscle contractions that result in twisting body motions, abnormal posture, and tremors.
The involuntary movements may involve the entire body or only an isolated area. Associated symptoms of dystonia may include rapid eye blinking or closing, foot cramps, turning or dragging of the leg or foot, worsening in handwriting, neck movements, or difficulty speaking. The symptoms may worsen when the individual is tired or under stress. Sometimes the involuntary movements of dystonia may be painful.
Cause of dystonia
Several different disorders can cause dystonia. For example, genetic or inherited conditions or taking certain medications (particularly antipsychotic drugs) may cause dystonia. It also may be a symptom of other diseases.
