OBJECTIVES
To evaluate the effect of ankle-foot orthosis on lower limbs kinematic segmental covariation (KSC) among stroke patients.
METHODS
Ten chronic hemiparetic spastic stroke patients presenting with a lack of ankle dorsiflexion were assessed with instrumented gait analysis under three conditions: wearing a shoe, with a prefabricated ankle-foot orthosis (AFO), and with a dynamic AFO. Kinematic parameters were recorded and computed KSC was calculated according to Borghese's methodology.
RESULTS
Contrary to the prefabricated AFO, the dynamic AFO improved KSC of the paretic side. We observed a high correlation between the external mechanical work and the affected side's KSC. In the unaffected side, KSC was globally unchanged.
CONCLUSION
In stroke patients, wearing a dynamic AFO improves KSC of the paretic lower limb only.
目的
评估踝足矫形器对脑卒中患者下肢运动节段协变（KSC）的影响。
方法
10 名慢性偏瘫痉挛性脑卒中患者存在踝关节背屈不足，在三种情况下进行仪器步态分析评估：穿鞋子、预制踝足矫形器（AFO）和动态 AFO。记录运动学参数，并根据 Borghese 的方法计算运动节段协变。
结果
与预制 AFO 相反，动态 AFO 改善了患侧的 KSC。我们观察到外部机械功与患侧 KSC 之间存在高度相关性。在非患侧，KSC 整体上没有变化。
结论
在脑卒中患者中，仅动态 AFO 可改善患侧下肢的 KSC。
