Answer

Order lumbar puncture with cerebrospinal fluid (CSF) analysis when clinically or electrophysiologically indicated.

CSF proteins may be elevated in multifocal motor neuropathy.

Oligoclonal immunoglobulin G (IgG) bands and antibodies to the poliovirus may be detected in the CSF of patients with PPMA.
