title: Motor function levels and pelvic parameters in walking or ambulating children with cerebral palsy.
abstract: BACKGROUND
  In children with cerebral palsy, spinal equilibrium and pelvic strategies may vary according to the functional status.
  
  
  OBJECTIVE
  To study the relationship between motor function and pelvic and spinal parameters in a population of children and adolescents with cerebral palsy (rated from level I to level IV on Gross Motor Function Classification System [GMFCS]). A sagittal X-ray of the spine in the standing position was analyzed with Optispine(®) software.
  
  
  RESULTS
  The study population comprised 114 children and adolescents (mean [range] age: 12.35 [4-17]). For the study population as a whole, there were significant overall correlations between the GMFCS level on one hand and pelvic incidence and pelvic tilt (PT) on the other (P=0.013 and 0.021, respectively).
  
  
  CONCLUSIONS
  Pelvic parameters vary according to the GMFCS level but do not appear to affect spinal curvature. The sacrum is positioned in front of the head of the femur (i.e. negative PT) in GMFCS level I and progressively moves backwards (i.e. positive PT) in GMFCS levels II, III and IV.
