Paramyotonia congenita is a disorder that affects skeletal muscles used for movement.It causes problems with the tone and contraction of skeletal muscles.People with this condition experience bouts of sustained muscle tensing which prevent muscles from relaxing normally. Myotonia causes muscle stiffness that typically appears after exercise and can be induced by muscle cooling. This stiffness chiefly affects muscles in the face, neck, arms, and hands, although it can also affect muscles used for breathing and muscles in the lower body.
HOW IS PARAMYOTONIA CONGENITA DIAGNOSED?
It is diagnosed by an electromyographic (EMG) examination. During this test fine needles are inserted into the muscle and the muscle’s electrical signals are recorded. The muscle is chilled for this test, as chilling brings on the myotonia. Evidence of myotonia supports the diagnosis of PMC.
HOW IS PARAMYOTONIA CONGENITA TREATED?
The treatment of the condition will be done with the help of care and management. Various kinds of physical and occupational therapy can help in keeping the muscle tensing bouts to a minimum. Also, with therapy, the patient can learn to make good use of whatever motion is left in those muscles.
DID YOU KNOW?
Patients with more severe PMC can experience shortness of breath or tightness in their chest muscles.
