Pain was reported by 63 of the 102 participants but no
significant association between posture and pain was found
in this study. There was less reported pain compared to
previous studies of adults with CP by Jahnsen et al.11
(82%) and Andersson and Mattsson12 (79%). It may be
due to the older age of participants in their studies (mean
age 34y and 36y respectively). Another reason could be
that pain may be unrecognized in some of the participants
in the present study, as people with severe intellectual and
communication disabilities were included.
Limited hip and knee extension were highly associated
with postural asymmetries. Andersson and Mattson12
reported contractures in 80% of 221 adults with CP; knee
contractures were most frequent. In the present study knee
contractures were also most common; 60 of the 102 adults
with CP could not passively extend one or both knees to 0
degrees. Limited hip and knee extension were associated
with postural asymmetries in both supine and standing
positions which require extended legs.
