Stiff-person syndrome(SPS) is a rare neurologic disorder with autoimmune features.It is characterized by progressive,severe muscle rigidity or stiffness most prominently affecting the spine and lower extremities.It is frequently associated with diabetes and other autoimmune diseases.The diagnosis of SPS is based on clinical grounds,however,aided by electromyography and high serum titers of antibodies against glutamic acid decarboxylase.Intravenous immunoglobulin infusions,plasmapheresis and steroids provide additional and lasting benefit.Moreover,benzodiazepines,baclofen,tiagabine and botulinum toxin A can afford symptomatic relief.
