What is Myotonia Congenita?

A condition in which the muscles used for movement are affected is known as myotonia congenital. During childhood, bouts of sustained muscle tensing are experienced that make the relaxation of muscles problematic. The condition can affect any skeletal muscle like muscles of face and tongue but, it usually occurs in the legs. The disorder makes the muscle stiff which can hinder the movement. While in some cases the stiffness is mild, in some cases it can interfere with walking, running and other activities.

In many cases, it has been noticed that repeated movements can soother their muscle stiffness which is known as warm-up effect.

Types of Myotonia

There are two main types of myotonia: Tomsen disease and Becker disease. Both these types can be differentiated by their symptoms and their patterns of inheritance. Becker disease is usually seen in later childhood days and its symptoms are more severe. People who suffer from Becker disease often experience temporary attacks of muscle weakness, especially in parts like arms and hands. A mild and permanent  muscle weakness can also be experienced over time.

However, muscle weakness cannot be seen on people suffering from Thomsen disease.

Myotonia Congenita Prognosis

People suffering from myotonia congenital can do well in life. The symptoms only start occurring when a movement first begins. Once in movement the muscle relaxes and the movement becomes smooth. However in some cases, the effects worsen with movement and improve later in life.
