Key result
Long-term follow-up of 14-16 years in persons with prior poliomyelitis showed only small changes in muscle strength and disability, indicating slower deterioration than previously thought.
Why the study?
It remained unclear whether symptoms in patients with late effects of polio worsen over time, and if so, the extent and rate of that decline.
Population
Fifty-two community-dwelling patients with prior poliomyelitis recruited from an earlier 4-year follow-up
Design
Cross-sectional longitudinal study
Follow-up
14-16 years post their first assessment

Supports slower-than-expected decline in prior poliomyelitis; leaves open prospective studies to refine monitoring.
Cross-Sectional (n=52)
In patients with prior poliomyelitis, deterioration in muscle strength and disability over 14-16 years is small and slower than previously thought.
Willén et al. (2020) conducted a cross-sectional in postpolio syndrome (PPS) (n=52). Time (14-16 years post first assessment) was evaluated on Long-term changes in disability, muscle strength, walking speed, and handgrip force. Long-term follow-up of 14-16 years in persons with prior poliomyelitis showed only small changes in muscle strength and disability, indicating slower deterioration than previously thought.
