title: Pathophysiology and diagnosis of post-polio syndrome.
abstract: Post-poliomyelitis syndrome is defined as a clinical syndrome of new weakness, fatigue and pain which can occur several decades following recovery from paralytic poliomyelitis. The cause of this disorder is still unclear, and many possible etiologies have been proposed. The most widely accepted etiology was first proposed by Wiechers and Hubbell, which attributes PPS to a distal degeneration of massively enlarged post-polio motor units. Other probable contributing factors to the onset of this disease are the ageing process, and overuse. Currently, there is no specific diagnostic test for PPS, which continues to be a diagnosis of exclusion in an individual with symptoms and signs of the disorder.
