Post-polio sequelae--differential diagnosis and management.

Forty-two patients with a past history of poliomyelitis were evaluated at a post-polio clinic for new problems or impairments. Evaluation included a complete history, neurological and biomechanical examination and electrodiagnostic studies. Based on this evaluation patients were placed into three groups: 23 patients were considered to have or likely to have Progressive Post-Polio Muscular Atrophy (PPPMA); 17 patients were considered to have other post-polio sequelae; and two patients had problems unrelated to a past history of polio but mistaken for post-polio sequelae. Musculoskeletal pain was a common complaint among all groups of patients. Twenty-two of the 40 patients with post-polio sequelae were advised to alter their method of ambulation and/or decrease their activity pattern in order to decrease strain and/or excessive exertion of involved muscles. The role of chronic overuse and exercise in producing PPPMA or musculoskeletal pain problems is discussed. Characteristic clinical problems and useful management plans are described.
