[A contribution to "stiff man" syndrome].

Abstract

A patient with the clinical symptoms of the "Stiff-man"-syndrome, but an atypical course was introduced. Symptoms and course were compared with similar cases mentioned in literature. The "Stiff-man"-syndrome is probably a disease of central origin affecting the relationship between inhibitory and excitatory regulation of the muscle tonus, especially the exteroceptive reflex mechanisms. Several pathological processes of the CNS can be held responsible for the disturbance of the balance in this regulatory system.
