Brief Summary
Polio or poliomyelitis is the disease caused by the poliovirus. The virus attacks cells in the spinal cord and causes symptoms of fever, sore throat, headache, vomiting, and stiffness of the neck. Patients with polio can have long-term weakness of muscles as a result of the damaged cells in the spinal cord. Occasionally, patients that recover from the disease can experience a relapse of muscle weakness. This can occur as long as 25-35 years after first having polio. The condition is called "post-polio syndrome". Not all nerve cells in the spinal cord are damaged by the poliovirus. Some nerve cells remain healthy and take over the work of the damaged cells. Researchers believe that the "post-polio syndrome" may be caused by failure of these overworked nerve cells. However, what causes these overworked nerve cells to disintegrate is unknown. The purpose of this study is to apply specific scientific tests to answer important questions about the causes and development of the post-polio syndrome. Researchers will investigate possible genetic, immunologic, and physiologic causes of the "post-polio syndrome". The study itself will not provide therapy for patients with the condition, but may lead to the development of therapies in the future.

Eligibility Criteria
You may qualify if:
- Patients with prior history of a well documented acute paralytic poliomyelitis with or without development of new neuromuscular symptoms after a minimum of 15 years from the acute illness will be studied.
- Patients will be screened in the outpatient clinic and will be studied as inpatients (or, if stable, as outpatients) for three day stay.
- Severly disabled patients with unstable respiratory function or those who require intensive care nursing or respiratory assistance will be excluded from the study.
