Except when there are symptoms of excessive exhaustion, aerobic activity is suggested for most people with post-polio syndrome. To gain a safe cardiovascular benefit, it is critical to choose the optimal sort of activity. Walking is the best choice for most people with post-polio syndrome because it is easy to start and maintain and does not require special equipment. Other options include swimming, dancing, hiking, cross-country skiing, and tennis. People who have post-polio paralysis of the respiratory system may experience relief from symptoms by engaging in aerobics or other types of vigorous exercise. However, excessive fatigue after such activities should be expected and encouraged so that the person can rest before continuing with other activities of daily life. Those who experience pain during or after exercise should decrease their activity level until the pain subsides. When possible, changing one's exercise routine or limiting strenuous activity should reduce the risk of further injury. If an injury does occur, be sure to seek medical advice before returning to exercise. Exercise is recommended for everyone with post-polio syndrome. The only people who should not engage in physical activity are those who currently suffer from severe fatigue or exhaustion due to their condition. These individuals should avoid activities that they cannot stop after beginning, such as walking on rough surfaces or up hills.
