Also known as: Stiff Man Syndrome

Stiff person syndrome (SPS; sometimes called stiff man syndrome in the medical literature) is a rare neurological disease that affects approximately 1 in 200,000 individuals – both male and female.

In this article

What are the symptoms of stiff person syndrome?


This condition is characterised by progressive stiffness and painful spasms in the back and limbs, which are often triggered by touch, noise or anxiety, and exacerbated by movement.

This is a progressive condition, but only exceptionally does stiffness increase to the extent that the person will require use of a wheelchair.

About 40% of individuals also have type 1 diabetes (see entry Diabetes Mellitus).

Three types of stiff person syndrome have been described:

What are the causes of stiff person syndrome?

SPS is an autoimmune condition meaning that the body’s immune system attacks ‘self’, when it should only attack foreign organisms, such as bacteria and viruses.

How is stiff person syndrome diagnosed?

Diagnosis of SPS can often take a long time, simply because it is so rare and the symptoms can baffle doctors. There are two important tests that can be carried out as a means to obtaining a diagnosis. The first test is for autoimmune antibodies. The commonest of these is an antibody to an enzyme called glutamic acid decarboxylase (GAD) involved in the generation of an inhibitory chemical messenger. Individuals with classic type 1 diabetes may show a similar antibody, although generally in much weaker concentrations. Other antibodies may also be found in the SPS, especially in the variant called jerking stiff person syndrome or progressive encephalomyelitis with rigidity. Here, antibodies include two to the receptors for two other chemical messengers – NMDA and glycine. The second test is an electromyogram (EMG), which is a muscle recording study.

How is stiff person syndrome treated?

While treatments do not lead to a cure, they can control symptoms in the majority of individuals. Some individuals are more responsive to certain treatments than others. The most effective drug treatments are diazepam and baclofen, which help reduce stiffness. Some patients with more severe symptoms need therapies that manipulate their immune systems. The commonest of these treatments is intravenous infusions of immunoglobulins.

Inheritance patterns and prenatal diagnosis

Inheritance patterns
SPS is not inherited, although there may be a family predisposition to other autoimmune diseases like diabetes mellitus and thyroid disorders.

Prenatal diagnosis
None available.
