Related people

A syndrome characterised by persistent muscle movement and with delayed relaxation following muscle contraction.

Description

A syndrome affecting both sexes in which peripheral nerve disease causes rigidity of the muscles. Onset usually in late childhood or early adulthood. Characterised by intermittent or persistent rippling muscle movements (myokymia) and delayed relaxation following muscle contraction. Increased muscle activity during sleep. Involvement of pharyngeal or laryngeal muscles may interfere with speech and breathing. Both acquired and familial forms have been described.
