Abstract
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.
