A Syndrome of Continuous Muscle-Fibre Activity

The purpose of this paper is to describe two cases of a hitherto unknown syndrome superficially resembling myotonia. Detailed studies have helped to separate this syndrome of continuous musclefibre activity from a group of 100 myotonic subjects, and it will be referred to in this paper as the 'syndrome of continuous muscle-fibre activity'. This descriptive label has been chosen, though the more imaginative may favour 'armadillo disease', a name by which these cases are likened to the slow moving, armour-plated quadruped.
