Changes in gluteal pressure and center of force during sitting in children with cerebral palsy.
Do Hyun Kim, Won-Gyu Yoo, Ji-Hye Do
PMID 29643607WHAT IT FOUND
Children with cerebral palsy had higher peak gluteal pressure and a more posterior center of force while sitting than typically developing peers.
Check seating pressure relief, but this small study did not test interventions.
Key findings
01Peak gluteal pressure during sitting was higher in children with cerebral palsy (0.44 ± 0.05 kg/cm2) than in typically developing controls (0.31 ± 0.06 kg/cm2) (p=0.016).
02Center of force during sitting was higher in children with cerebral palsy (12.38 ± 1.26 cm) than in typically developing controls (8.58 ± 0.61 cm) (p=0.009).

What it does not show
Only five children with cerebral palsy and five controls were studied, so the findings may not be stable. Children had to be able to sit independently for 5 minutes and had no sensory deficits, so the study says little about children who cannot sit independently or who have sensory problems. The study compared groups at one time; it did not test seating, therapy, or skin protection interventions. Measurements were made on a therapeutic table for 1 minute without back or foot support, which may not match a child's usual chair or wheelchair.
The easy way to misread this
Do not conclude that a specific seating change will lower gluteal pressure or improve sitting balance. This study only measured differences in five children with cerebral palsy and five controls and did not test any intervention.
