Post-polio syndrome (PPS) is a condition that affects polio survivors. About 20% to 40% of people who recover from polio will later develop PPS. The onset may occur 10 to 40 years after the initial polio attack.
The exact cause is unknown. It is not due to the original polio virus itself. Instead, the syndrome is due to nerve and muscle damage that may have been caused by the original infection.
Factors that may increase your chance of developing PPS include:
Symptoms may include:

Treatment may include:
