The time to onset of these symptoms can vary, but averages about 30 years after the acute episode of polio. The patient experienced neurological recovery after APP, followed by at least a 20-year period of stabilization Other causes for the person's complaints and other findings have been ruled out. PPS seems to be caused by the decompensation of a process that worked well for the patient many years. A balance existed between the death of nerve fibers and the growth and sprouting of new nerve fibers.

Muscle weakness occurs.
Both questions are very difficult to answer with any certainty. In addition, people frequently complain of a new intolerance to cold, atrophy of their muscles, difficulty climbing stairs and a decreased ability to perform their activities of daily living. As the weakness progresses, it may affect mobility and produce new handicaps or disabilities. Stair climbing is the most frequently affected, followed by increased difficulty performing activities of daily living such as cooking, cleaning or driving. Once the weakened muscles have been identified, strengthening exercises and aerobic exercises are very helpful.
