摘要： 目的分析悬吊方式和步速对两种小腿假肢接受腔悬吊的影响。方法制作带聚乙烯基(EVA)内衬套的PTK小腿假肢和带锁硅胶衬套小腿假肢,由一位熟练使用小腿假肢的患者穿戴,使用红外线摄像仪进行步态分析测试,采集一个标准步态周期数据进行数据分析。结果PTK接受腔和带锁硅胶衬套接受腔的小腿假肢悬吊位移差异有显著性意义(P<0.05);PTK小腿假肢在不同步速下产生的悬吊位移差异有显著性意义(P<0.05～0.001)。结论PTK小腿假肢和带锁硅胶小腿假肢在不同的步速下行走对假肢的悬吊可产生不同程度的影响。

Abstract: Objective To analyze the effects of suspensory manner and step speed on suspension of crus prosthesis.Methods The Prothèse Tibiale Kegel(PTK) crus prostheses with EVA soft socket and silicone socket were made and dressed by one patient who was familiar to dress crus prothesis.The gait analysis was performed with infrared ray imaging.Results The displacement of suspension induced by PTK crus prosthesis was different from those induced by prosthesis with silicone liner locked(P<0.05),and had the different displacements under different step speed(P<0.05～0.001).Conclusion The PTK crus prosthesis and that with silicone liner locked have different effects on suspension under different step speed.
