Postural asymmetries, pain, and ability to change position of children with cerebral palsy in sitting and supine: a cross-sectional study

Purpose To examine any associations between postural asymmetries, postural ability, and pain for children with cerebral palsy in sitting and supine positions. Methods A cross-sectional study of 2,735 children with cerebral palsy, 0-18 years old, reported into the Swedish CPUP registry. Postural asymmetries, postural ability, the gross motor function classification system levels I-V, sex, age and report of pain were used to determine any relationship between these variables. Results Over half the children had postural asymmetries in sitting (n = 1,646; 60.2%) or supine (n = 1,467; 53.6%). These increased with age and as motor function decreased. Children were twice as likely to have pain if they had an asymmetric posture (OR 2.1-2.7), regardless of age, sex and motor function. Children unable to maintain or change position independently were at higher risk for postural asymmetries in both supine (OR 2.6-7.8) and sitting positions (OR 1.5-4.2). Conclusions An association was found between having an asymmetric posture and ability to change position in sitting and/or lying; and with pain. The results indicate the need to assess posture and provide interventions to address asymmetric posture and pain.
