摘要:

背景:脑卒中偏瘫患者使用康复支具可明显提高其运动功能。
目的:探讨脑卒中偏瘫支具材料的种类及生物相容性。
方法:以“脑卒中,偏瘫,支具,材料;Cerebral apoplexy,hemiplegia,support,material”为关键词,应用计算机检索1999至2015年万方数据库、清华知网数据库、PubMed数据库,选取有关脑卒中偏瘫与支具材料生物相容性研究的文献,同一领域文献选择权威杂志或发表时间为近期的文献,依据纳入排除标准选取15篇文献进行归纳分析。
结果与结论:热塑矫形器主体采用聚丙烯材料制成,用于脑卒中偏瘫引起的足下垂,聚丙烯材料强度高、韧性好,安全无毒,半硬的足底在摆动期可以协助足尖的提起。高分子纤维材料矫形器的特点是使用简便、韧性好、强度高,透气性能好,不会影响X射线检查。碳纤维材料质轻、比强度、比模量高,抗疲劳性能好,可设计性强,安全性能好。聚丙烯和碳纤维材料踝足矫形器临床实验研究发现,脑卒中偏瘫患者佩带聚丙烯踝足矫形器后在步行距离和爬楼梯速度方面有提高,患者感觉更加平衡和安全。通过对不同材料矫形器的实验研究,可以从中获得更多患者的使用偏好,对矫形器材料今后的开发和设计有很大帮助。

Abstract:

BACKGROUND: Rehabilitation brace can significantly improve the motor function of patients with post-stroke hemiplegia.
OBJECTIVE: To investigate the types and biocompatibility of brace materials for post-stroke hemiplegia.
METHODS: A computer-based search of Wanfang, CNKI, PubMed databases was performed for articles related to post-stroke hemiplegia and biocompatibility of brace materials published from 1999 to 2015 using the keywords of “cerebral apoplexy, hemiplegia, support, material” in Chinese and English, respectively. In the same field, the articles published recently or in authoritative journals were preferred. Finally, 15 articles were enrolled in result analysis.
RESULTS AND CONCLUSION: Thermoplastic orthoses are mainly made of polypropylene materials, which are
used for foot drop caused by post-stroke hemiplegia. Polypropylene has high strength and good toughness, and it is also safe and non-toxic. Semi-rigid planta pedis can help the lift of the toe in swing phase. Orthoses made of polymer fiber materials are characterized by ease of use, good toughness, high strength, and good air permeability, which cannot impact X-ray examination. Carbon fiber materials have light mass, high specific strength and modulus, good anti-fatigue performance, good safety performance and good designability. Clinical trials have shown that patients wearing ankle foot orthoses made of polypropylene and carbon fiber materials have improvement in walking distance and speed of climbing stairs, and these patients also feel more balanced and secure. Experimental studies on different orthotics materials can get more patient preferences, which have a great help for the design and development of orthotics materials.
