目的 比较1例单侧大腿截肢者穿戴四种不同假肢膝关节后的步行能力,为临床开具假肢处方提供参考方法 1例单侧大腿截肢者分别穿戴机械四连杆、气压四连杆、液压单轴和智能假肢膝关节,穿戴智能日常活动能量消耗记录仪进行计时起立与行走测试、室内6分钟步行测试、静态站立平衡测试和室外1000 m步行测试。结果 截肢者穿戴智能膝关节假肢比穿戴其他膝关节假肢在步行过程中能量消耗少,步行速度快。结论 不同假肢膝关节对单侧大腿截肢者步行能力影响不同。
Objective To compare the walking abilities of an unilateral transfemoral amputee with four different prosthetic knee joints, to provide a reference for clinical prosthetic prescription.Methods An unilateral transfemoral amputee was asked to wear four kinds of prosthetic knee joints, mechanical four-bar, pneumatic four-bar, hydraulic and intelligent prosthetic knee joints, and evaluated with Timed Up and Go Test, indoor 6-Minute Walk Test, Static Stand Balance Test and a 1000-meter Outdoor Walking Ability Test, wearing Intelligent Device for Energy Expenditure and Activity.Results The amputee consumed the least energy and walked the fastest with intelligent prosthetic knee joint.Conclusion There are some difference in walking ability with different prosthetic knee joints.
