[Purpose] Observational study investigating the influence of various ankle-foot orthoses on the spatiotemporal gait parameters and functional balance in chronic stroke patients. [Subjects and Methods] Fifteen chronic stroke patients participated in this study after providing informed consent. Two groups of patients were differentiated based on the Timed Up and Go Test. Patients were tested in three different conditions: with standard prefabricated ankle-foot orthosis (Maramed), with individualized ankle-foot orthosis (Y-tech), and without any ankle-foot orthrosis. Spatiotemporal gait parameters were obtained by walking on an instrumented walkway (GAITRite(®)) at usual and fastest speed. Balance was assessed with Timed Up and Go Test, Step Test, and Four Square Step Test. [Results] Maramed and Y-tech significantly improved the spatiotemporal parameters while walking at usual and maximal speed (single support time affected side; double support time affected side and step length unaffected side). The Y-tech in addition improved velocity and cadence. Among the balance tests, only the Timed Up and Go test showed improvements in favor of Maramed and Y-tech. [Conclusion] Patients benefited from wearing orthosis at both usual and maximal speed, irrespective of whether they wore Maramed or Y-tech. Only severe stroke patients benefited from wearing an orthoses compared to mild impaired group.
[目的] 一项观察性研究，旨在调查各种踝足矫形器对慢性中风患者时空步态参数和功能平衡的影响。[对象与方法] 15名慢性中风患者在签署知情同意书后参与了本研究。根据定时起立行走测试将患者分为两组。患者在三种不同条件下进行测试：佩戴标准预制踝足矫形器（Maramed）、佩戴个性化踝足矫形器（Y-tech）以及不佩戴任何踝足矫形器。通过在装有仪器的通道（GAITRite(®)）上以正常和最快速度行走来获取时空步态参数。使用定时起立行走测试、台阶测试和四方步测试来评估平衡能力。[结果] Maramed和Y-tech在以正常和最大速度行走时显著改善了时空参数（患侧单支撑时间；患侧双支撑时间以及健侧步长）。此外，Y-tech还提高了速度和步频。在平衡测试中，只有定时起立行走测试显示出Maramed和Y-tech有改善效果。[结论] 患者无论佩戴Maramed还是Y-tech，在正常和最大速度行走时佩戴矫形器均有益处。与轻度受损组相比，只有重度中风患者佩戴矫形器有益。
