This study examined the relationship between the Gait Deviation Index (GDI) and walking activity preoperatively and postoperatively.The GDI and walking activity from 74 youth with cerebral palsy (CP) were included in the analysis. The preoperative GDI was calculated using gait parameters collected during a clinical gait analysis 1 to 16 months prior to surgery. The postoperative GDI was calculated using gait parameters collected during a clinical gait analysis 10 to 26 months following surgery.A weak correlation was present between the change in the average GDI and the change in strides. A moderate correlation was found between the change in the Surgery GDI and the change in strides.Single-event multilevel surgery improves gait deviations in children with CP. However, the improvement in gait pattern has limited correlation with postoperative change in walking activity. Our results demonstrate a need to pair surgical with additional intervention to affect long-term improvements in walking activity.
