Immobile arm in children with neurologic deficits

CNS: central nervous system.
* Erb or Klumpke palsy. Acute flaccid myelitis can present as isolated arm weakness or with cranial nerve weakness, weakness in other extremities, or signs of encephalitis.
¶ In some patients with rapid return of normal function, the diagnosis of Todd paralysis may be made without neuroimaging, especially those with a history of prior episodes.
