The stiffness primarily affects the truncal muscles and is superimposed by spasms, resulting in postural deformities. Autoimmune and paraneoplastic neurologic syndromes (adult). (2005) demonstrated that intraperitoneal injection of purified plasma anti-amphiphysin IgG antibodies from a patient with paraneoplastic SPS (Wessig et al., 2003) into female rats resulted in dose-dependent stiffness with spasms resembling human SPS.

The cause of SPS is unknown, but it is an autoimmune disorder (malfunction of the immune system, where the body produces antibodies against its own tissues). It is generally safe, but there are possible serious side effects, and it is expensive. Stiff-person syndrome causes muscle stiffness that worsens gradually.
