Objective: To compare lung function between patients with post-poliomyelitis syndrome and those with sequelae
of paralytic poliomyelitis (without any signs or symptoms of post-poliomyelitis syndrome), as well as between
patients with post-poliomyelitis syndrome and healthy controls. Methods: Twenty-nine male participants were
assigned to one of three groups: control; poliomyelitis (comprising patients who had had paralytic poliomyelitis
but had not developed post-poliomyelitis syndrome); and post-poliomyelitis syndrome. Volunteers underwent
lung function measurements (spirometry and respiratory muscle strength assessment). Results: The results of
the spirometric assessment revealed no significant differences among the groups except for an approximately
27% lower mean maximal voluntary ventilation in the post-poliomyelitis syndrome group when compared with
the control group (p = 0.0127). Nevertheless, the maximal voluntary ventilation values for the post-poliomyelitis
group were compared with those for the Brazilian population and were found to be normal. No significant
differences were observed in respiratory muscle strength among the groups. Conclusions: With the exception of
lower maximal voluntary ventilation, there was no significant lung function impairment in outpatients diagnosed
with post-poliomyelitis syndrome when compared with healthy subjects and with patients with sequelae of
poliomyelitis without post-poliomyelitis syndrome. This is an important clinical finding because it shows that
patients with post-poliomyelitis syndrome can have preserved lung function.
