What is post-polio syndrome (PPS)?
PPS is a condition that affects polio survivors ten to 40 years after recovery from an initial infection. PPS is characterized by further weakening of muscles that were previously affected by the polio infection. Symptoms include fatigue, slowly progressive muscle weakness and deterioration. Joint pain and bone deformities are common. PPS is generally not life-threatening. There is no known cause or effective treatment for PPS.
