INTRODUCTION
Gait Deviation Index (GDI) describes the overall gait quality and summarizes it into a single score based upon three-dimensional gait analysis (3DGA). In the Region of Southern Denmark, children with cerebral palsy (CP) are referred to 3DGA if surgical intervention is considered and subsequently, as a follow-up. Thus, the effect of treatment on gait quality in children with CP may be quantified. In a retrospective study we investigated the effect of treatment on gait quality (measured by GDI) in children with CP.
METHODS
Data from children (<16 years) diagnosed with CP and referred to 3DGA (either as a diagnostic instrument or for the purpose of follow-up) was extracted from a local database for the year 2012. The GDI score was calculated for each child and limb and used for further analysis
RESULTS AND DISCUSSION
29 children with follow-up analysis were referred to 3DGA in 2012. Children were diagnosed with unilateral (n = 6) or bilateral spastic CP (n = 23). Age and GDI score at first 3DGA were 8.2 ± 2.8 years and 69 ± 11 (mean ± sd), re-
tively. Time between follow-ups was 710 ± 367 days.
A weak, albeit non-significant association between GDI and age was observed (r = 0.25, 95CI: -0.13 to 0.56), suggesting
the effect of age is only weakly reflected in gait quality. However, a significant negative association (r = 0.41, 95CI: -0.93 to -0.24) between GDI at first 3DGA and the improvement in GDI was observed (Figure 1). Proposing, that children with poor gait quality at baseline, benefit more from intervention than children with good.
CONCLUSIONS
Significant improvements in GDI, especially for patients with poor gait quality, were observed. The present study holds promise for future clinical interpretations, involving more patients, and possibly providing a tool for stratification on different treatments.
