The most common long-term problems seen in polio are brace problems, knee recurvatum, increasing weakness due to overuse and ankle equinus. A definite increased incidence of problems is seen after the patient is more than 30 years post-polio. The basis for most of these problems is chronic mechanical strain of weak musculature and substituting ligaments. Overuse can cause increasing weakness resulting in pain and decreasing function. It is therefore important to follow polio patients closely, especially those that are more than 30 years post-polio. If signs of overuse or chronic mechanical strain are noted, treatment should not be delayed.
小儿麻痹症最常见的长期问题包括支具问题、膝反屈、因过度使用导致的肌无力加重以及马蹄内翻足。小儿麻痹症患者发病30年后，这些问题的发生率明显增加。这些问题大多是由于虚弱肌肉组织和替代韧带的慢性机械性劳损所致。过度使用会导致肌无力加重，从而引起疼痛和功能下降。因此，密切关注小儿麻痹症患者非常重要，尤其是那些发病已超过30年的患者。如果发现过度使用或慢性机械性劳损的迹象，应及时进行治疗。
