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.
本研究探讨术前及术后步态偏差指数（GDI）与步行活动之间的关系。
分析74例青年脑瘫（CP）患者的GDI和步行活动情况。术前GDI采用手术前1至16个月临床步态分析收集的步态参数计算得出。术后GDI采用手术后10至26个月临床步态分析收集的步态参数计算得出。
平均GDI变化与步幅变化之间存在弱相关性。手术GDI变化与步幅变化之间存在中度相关性。
单阶段多级手术可改善CP患儿的步态偏差。然而，步态模式的改善与术后步行活动变化的相关性有限。我们的结果表明，需要将手术与其他干预措施相结合，以实现步行活动的长期改善。
