Post-Polio Syndrome (PPS) is a neurological condition that affects polio survivors decades after they first recovered from the acute illness. It is characterized by the gradual weakening of muscles that were previously injured by the polio virus, often accompanied by new muscle atrophy, severe fatigue, and joint pain. The leading theory suggests that PPS arises because the surviving nerve cells that had taken on extra work for years become overstressed and start to fail. Management focuses on energy conservation, physical therapy, and using assistive devices to reduce strain and maintain quality of life.
