Gait laboratory data of 233 patients with cerebral palsy were studied retrospectively. Two groups were selected; those who demonstrated pelvic retraction during gait <-6.85 degrees (mean - 2 standard deviations from normal (n=88) and those with >-4.83 degrees (mean - 1 standard deviation from normal) (n=101). About 37.8\% of the total population reviewed showed pelvic retraction of <-6.85 degrees . There was a higher prevalence of retraction among hemiplegics (46.3\%) compared to diplegics (30.4\%). Differences were also found between hemiplegic and diplegic subjects in terms of factors associated with pelvic retraction. Clinical and dynamic tightness of the gastro-soleus were the most significant features associated with pelvic retraction among hemiplegic subjects. Clinical and dynamic flexion and internal rotation of the hip were the most significant features associated with retraction in the diplegic population. This study suggests that pelvic retraction is multifactorial in origin and secondary to both static clinical measures as well as dynamic features during gait.
