Stiff Man Syndrome

Stiff Man Syndrome is a neuromuscular condition in which a hyperactive startle reflex results in the contraction of the muscles, thus causing violent spasms. These spasms are capable of slamming the victim into walls and furniture. The disorder’s cause is unknown, although evidence is pointing increasingly to the fact that it is an autoimmune disorder.

Although they appear completely normal, those afflicted with Stiff Man Syndrome must avoid any situation where they might be exposed to sudden sounds or stimulation. Often, they remain isolated in their home and excluded from normal living. They are orphaned from society by this rare and ruthless disorder.
