Post-Polio Syndrome

Years after recovering from paralytic poliomyelitis, a patient may notice that walking, transfers, or shoulder work now require more effort. The change is usually gradual and may include renewed weakness, fatigue, muscle pain, or loss of function in muscles affected during the original illness. That pattern raises post-polio syndrome (PPS), but it does not establish the diagnosis. The first bedside priority is safety: determine whether weakness is affecting breathing, secretion clearance, or swallowing. The diagnostic priority is to confirm a long period of stability and look for another explanation before attributing new symptoms to PPS. The distinction matters because PPS is managed by protecting remaining motor capacity, not by pushing weakened muscles harder.
