Myotonia is a symptom of disorders such as myotonic muscular dystrophy.A disorder of the muscle fibers that results in abnormally prolonged contractions. The patient has difficulty in relaxing a movement (e.g. his grip) after £my vigorous effort. It is a feature of a hereditary condition starting in infancy or early childhood (myotonia congenita) and of a form of muscular dystrophy (dystrophia myotonica).A condition in which the muscles, though possessed of normal power, contract only very slowly. The stiffness disappears as the muscles are used.Tonic spasm of a muscle or temporary rigidity after muscular contraction.The incapacity of a muscle to unwind even after the necessity for contraction has ended is known as myotonia. This phenomenon is a characteristic of myotonic dystrophy, a type of muscular dystrophy.
