General Discussion

Paramyotonia congenita is a rare muscular disorder inherited as an autosomal dominant trait. This nonprogressive disorder is characterized by a condition in which the muscles do not relax after contracting (myotonia). Symptoms can be triggered by exposure to the cold. There are also intermittent periods of a type of paralysis in which there is no muscle tone (flaccid paresis). This condition does not necessarily coincide with exposure to cold temperatures or myotonia. There is no wasting (atrophy) or increase in bulk (hypertrophy) of muscles with this disorder.
