科学领域:

假肢和整形
生物医学工程
康复科学

背景情况:

个性化的假肢插座设计依赖于熟练的假肢师平衡功能,舒适性和负载传输.
目前的方法 (石膏,CAD/CAM) 是代的,阻碍了知识共享.
使用过去的计算机辅助插座设计 (CASD) 记录,提供个性化的假肢安装起点.

研究的目的:

根据之前的CASD记录,评估由证据生成的 (EG) 假肢插座的舒适性.

主要方法:

一项交叉试验将EG插座与传统的临床医生主导的CAD/CAM插座进行比较,该试验涉及17名参与者,在英国3家NHS诊所进行了19次截肢.
主要结局结果是插座舒适度 (SCS) 的非劣势.
进行了半结构面试以进行深入的用户分析.

主要成果:

与临床医生主导的对照套件相比,EG套件的舒适度没有显著的差异 (SCS中位数为8. 6与8. 8).
在不同参与者之间,EG插座的SCS变异性较低.
定性分析揭示了适应体验,口比较和影响舒适度的残余肢体因素的主题.

结论:

在插座舒适性方面,EG插座与传统的CASD实践无差.
临床医生的意见至关重要,
未来的工作旨在将EG插座集成到CASD软件中,作为专家临床医生修改的数字起点,优化定制和共同设计.
