5 Facts you should know about

Stiff person syndrome (SPS)

Symptoms may include extreme muscle stiffness, rigidity and painful spasms in the trunk and limbs, severely impairing mobility

Initially, stiffness occurs in the thoracolumbar paraspinal and abdominal muscles

People with SPS often have heightened sensitivity to noise, sudden movements, and emotional distress, which can set off muscle spasms

Spasms can generate enough force to fracture a bone

Persistent symptoms can lead to abnormal posturing of the spine
