Post-polio syndrome (PPS) is a condition that affects individuals who have already had polio, usually decades after their initial infection. It is characterized by a slow but progressive weakening of muscles that were previously affected by polio. The most common presentation of PPS is a gradual decrease in muscle strength, endurance, and coordination.
The initial signs and symptoms of PPS can include fatigue, muscle pain, joint pain, difficulty sleeping, difficulty swallowing, breathing problems, and weakness in muscles that were previously affected by polio. As the condition progresses, these symptoms can become more severe and lead to a loss of muscle strength, mobility, and function.
In some cases, individuals with PPS may experience a decrease in muscle size, decreased reflexes, and muscle spasms. They may also experience difficulty walking, difficulty climbing stairs, and difficulty standing up from a seated position.
The exact cause of PPS is unknown, although it is believed to be due to a combination of factors, such as the body’s natural aging process, the weakening of the muscles due to lack of use, and the body’s response to the original polio virus.
There is no cure for PPS. However, there are treatments available to help manage the symptoms and improve quality of life. These treatments may include physical and occupational therapy to help maintain muscle strength and function, medications to reduce pain and fatigue, and assistive devices to help with mobility.
