背景：使用油阻尼器的踝足矫形器旨在使踝关节能够自然运动。佩戴带油阻尼器的踝足矫形器已被证明可以辅助脑卒中患者的第一摇臂，但其在不佩戴时对步态的影响尚不清楚。目的：确定使用带油阻尼器的踝足矫形器对脑卒中偏瘫患者不佩戴踝足矫形器时的步态影响。研究设计：交叉研究。方法：8名中风慢性期患者不佩戴踝足矫形器时的步态效果。在使用带油阻尼器的踝足矫形器之前，使用三维运动分析系统对踝足矫形器进行测量，然后在使用3周后，在不使用和使用带油阻尼器的踝足矫形器的情况下对踝足矫形器进行测量。比较了三种测量条件下步态的差异。结果：使用油阻尼器踝足矫形器显着缩短了预旋时间，并显着增加了不佩戴油阻尼器踝足矫形器时站立时的正踝关节力量。结论：这些变化表明使用油阻尼器踝足矫形器具有良好的治疗效果，并表明使用油阻尼器踝足矫形器作为治疗装置的潜力。临床相关性经过3周的研究使用辅助第一摇杆的油压减震踝足矫形器，改善了慢性期中风患者在不佩戴油压减震踝足矫形器时的步态。预摆时间显着减少，踝关节正向力量显着增加。使用油阻尼器的踝足矫形器可辅助第一摇杆功能，使踝关节在步态中自然运动，短期使用后有望改善中风患者的步态。
Background: An ankle-foot orthosis using an oil damper is designed to enable natural movement of the ankle joint. Wearing an ankle-foot orthosis using an oil damper has been demonstrated to assist the first rocker in stroke patients, but its effect on their gait when not wearing it is unclear.Objectives: To determine the effect of use of ankle-foot orthosis using an oil damper on the gait of stroke patients with hemiparesis when not wearing the ankle-foot orthosis.Study design: Crossover study.Methods: The gait of eight stroke patients in the chronic phase when not wearing an ankle-foot orthosis was measured, using a three-dimensional motion analysis system, before using the ankle-foot orthosis using an oil damper and then without and with using the ankle-foot orthosis using an oil damper after 3 weeks of use. Differences in gait were compared between the three measurement conditions.Results: Use of ankle-foot orthosis using an oil damper significantly decreased preswing time and significantly increased the positive ankle joint power in stance when not wearing the ankle-foot orthosis using an oil damper.Conclusions: These changes indicate the promising therapeutic effects of ankle-foot orthosis using an oil damper use and suggest the ankle-foot orthosis using an oil damper's potential as a therapeutic device.Clinical relevance After 3 weeks of use of an ankle-foot orthosis using an oil damper, which assists the first rocker, the gait of stroke patients in the chronic phase when not wearing the ankle-foot orthosis using an oil damper was improved. Preswing time was significantly decreased and positive ankle joint power was significantly increased. The ankle-foot orthosis using an oil damper, which assists the first rocker function with natural movement of the ankle joint during gait, has the potential to improve the gait of stroke patients after immediate-term use.
