Factors that may increase your risk of developing post-polio syndrome include:

  • Severity of initial polio infection. The more severe the initial infection, the more likely that you'll have signs and symptoms of post-polio syndrome.
  • Age at onset of initial illness. If you acquired polio as an adolescent or adult rather than as a young child, your chances of developing post-polio syndrome increase.
  • Recovery. The greater your recovery after acute polio, the more likely it seems that post-polio syndrome will develop. This may happen because greater recovery places additional stress on motor neurons.
  • Physical activity. If you often perform physical activity to the point of exhaustion or fatigue, this may overwork already stressed-out motor neurons and increase your risk of post-polio syndrome.
