Hemidystonia is uncontrollable and often painful muscle contractions on one side of the body which cause awkward movements, postures and discomfort. Typically hemidystonia involves the arm and leg and is usually the result of injury or problem with the basal ganglia on the opposite side of the brain to the dystonia. A typical cause is stroke.

Symptoms may include:

  • Muscle spasm with or without pain
  • Twisted postures of the limb
  • Turning in of the foot and/or leg and/or arm
