Key result
Over 15 years of follow-up, poliomyelitis survivors demonstrated only a modest decline in neuromuscular function, with late deterioration symptoms associated with the magnitude of residual deficits.

Reassures polio survivors of modest long-term neuromuscular stability; leaves open targeted research on symptoms linked to residual deficits.
Cohort
In polio survivors, late deterioration symptoms are related to baseline residual deficits rather than ongoing functional decline over 15 years.
Sorenson et al. (2005) conducted a cohort in Prior poliomyelitis. Prior poliomyelitis was evaluated on Neuromuscular function (strength measurements, electrophysiologic assessments, and timed functional tasks). Over 15 years of follow-up, poliomyelitis survivors demonstrated only a modest decline in neuromuscular function, with late deterioration symptoms associated with the magnitude of residual deficits.
