Answer

Lumbar puncture and associated CSF studies should be obtained in patients with a presentation that is consistent with stiff person syndrome to rule out other etiologies. Oligoclonal bands can be observed in approximately two thirds of patients with antibody-positive stiff person syndrome. [20] In addition, lumbar puncture can add needed information if the patient's presentation is unusual or complex.
