In recent years, polio survivors often suffer new symptoms : post- polio syndrome (PPS). Pain, one of the criteria in PPS diagnosis, is a tough problem to handle. The purpose of this study was to investigate the prevalence of pain in polio survivors. We also investigated the difference of the pain prevalence in terms of different sites and the use of lower extremity orthosis. The subjects were 70 polio survivors who were ambulatory without canes or crutches. Fifty-two patients (74.3%) had the symptom of pain. The prevalence rate of pain was significantly higher in the lower extremities than the upper extremities, and in the less affected side than in the more affected side (p<0.05). In the less affected side, the prevalence rates were significantly higher in the knee joint and lower leg (p<0.05). In persons with the use of lower extremity orthoses, the prevalence rates were significantly lower in the knee joint and lower leg on the bad side (p<0.05). In conclusion, the symptom of pain is developed more frequently in distal parts of less affected extremities. In persons with the use of lower extremity orthoses, the prevalence rates were lower in the distal lower extremity on the bad side. The symptom of pain should be approached and treated comprehensively to improve the problem.
