Abstract
Objective
To evaluate whether medial knee support (MKS) in seating systems aggravates hip displacement
in children with cerebral palsy (CP).
Design
Retrospective chart review.
Setting
Rehabilitation department of tertiary university hospital.
Participants
Children with CP (N=76) using seating systems (intervention group, n=42; mean age
6.86y) and using regular wheelchairs (control group, n=34; mean age 8.15y).
Interventions
The intervention group was provided with a seating system with MKS. We enrolled children
who did not use a seating system in the control group, retrospectively.
Main Outcome Measures
By radiographic images, Reimer’s migration index (MI), lateral center edge angle (CEA),
and femur neck shaft angle (NSA) were measured. We compared the demographic data,
clinical variables, and radiographs between the 2 groups.
Results
In the intervention group, there was a significant deterioration in the MI, from 26.89%
to 44.18% after using the system (P<.001). The progression of MI was 14.72% and 7.82% per year in the intervention and
control groups, respectively (P=.016).
Conclusion
We should consider the possibility that seating systems with MKS may exacerbate hip
displacement in children with CP.
