Hand orthoses are often prescribed for persons with chronic hand and wrist impairments. This study assessed the feasibility, in terms of production time and user satisfaction, of 3-dimensional printed hand orthoses compared with conventional hand orthoses for this population.
In this prospective case series, both a conventional hand orthosis and a 3-dimensional printed hand orthosis were manufactured for 10 participants. Production time (in minutes) of each orthosis was recorded. Each orthosis was worn for one week, after which participants completed a self-designed questionnaire on satisfaction, scored on a 5-point Likert scale. Functionality and orthosis preference were also assessed.
The mean (standard deviation (SD)) production time for the 3-dimensional printed orthoses, of 112 (11.0) min, was significantly shorter compared with 239 (29.2) min for the conventional orthoses (95% confidence interval (95% CI) 71-182 min, 0.001). Satisfaction scores were similar for both orthoses, except for comfort item "fitting method", which was rated significantly higher for scanning compared with casting (median [IQR] score: 5 [0.0]; 4 [2.0], 0.034). Functionality and orthosis preference were rated similar for both orthoses.
As the production time was halved, user satisfaction similar, and scanning experienced as slightly more comfortable than casting, 3-dimensional printed hand orthoses seem feasible and potentially beneficial for use in people with chronic hand and wrist impairments.
手部矫形器常用于患有慢性手部和腕部损伤的人群。本研究从制作时间和用户满意度方面评估了3D打印手部矫形器与传统手部矫形器相比，应用于该人群的可行性。
在这个前瞻性病例系列研究中，为10名参与者分别制作了一个传统手部矫形器和一个3D打印手部矫形器。记录每个矫形器的制作时间（以分钟为单位）。每个矫形器佩戴一周，之后参与者完成一份自行设计的关于满意度的问卷，采用5点李克特量表评分。还评估了功能性和对矫形器的偏好。
3D打印矫形器的平均（标准差）制作时间为112（11.0）分钟，与传统矫形器的239（29.2）分钟相比显著更短（95%置信区间71 - 182分钟，P = 0.001）。两种矫形器的满意度评分相似，但在舒适度项目“适配方法”上，扫描方式的评分显著高于石膏模型法（中位数[四分位间距]评分：5[0.0]；4[2.0]，P = 0.034）。两种矫形器在功能性和偏好方面的评分相似。
由于制作时间减半，用户满意度相似，且扫描方式的体验比石膏模型法略舒适，3D打印手部矫形器对于慢性手部和腕部损伤患者似乎是可行的且可能有益。
