To assess the preliminary effectiveness of three-dimensional printed orthoses compared with conventionally custom-fabricated orthoses in persons with chronic hand conditions on performance of daily activities, hand function, quality of life, satisfaction, and production time and costs.
Interventional feasibility study.
Chronic hand orthotic users (n = 21).
Participants received a new three-dimensional printed orthosis according to the same type as their current orthosis, which served as the control condition. Primary outcome was performance of daily activities (Patient-Reported Outcomes Measurement Information System-Upper Extremity; Michigan Hand Questionnaire). Secondary outcomes were hand function, quality of life, and satisfaction. Furthermore, production time and costs were recorded.
At 4 months' follow-up, no significant differences were found between three-dimensional printed orthoses and participants' existing conventional orthoses on activity performance, hand function, and quality of life. Satisfaction with the three-dimensional printed orthosis was significantly higher and the production time and costs for three-dimensional printed orthoses were significantly lower compared with conventional orthoses. The three-dimensional printed orthosis was preferred by 79% of the participants.
This feasibility study in chronic hand conditions suggests that three-dimensional printed orthoses are similar to conventional orthoses in terms of activity performance, hand function, and quality of life. Satisfaction, and production time and costs favoured the three-dimensional printed hand orthoses.
评估三维打印矫形器与传统定制矫形器在慢性手部疾病患者日常活动表现、手部功能、生活质量、满意度以及制作时间和成本方面的初步疗效。
干预可行性研究。
慢性手部矫形器使用者（n=21）。
参与者根据与现有矫形器相同的类型获得新的三维打印矫形器，作为对照条件。主要结局指标为日常活动表现（患者报告的测量信息系统上肢问卷；密歇根手部问卷）。次要结局指标为手部功能、生活质量和满意度。此外，还记录了制作时间和成本。
在 4 个月的随访中，三维打印矫形器与参与者现有的传统矫形器在活动表现、手部功能和生活质量方面没有显著差异。与传统矫形器相比，对三维打印矫形器的满意度显著更高，制作时间和成本显著更低。三维打印矫形器得到了 79%的参与者的青睐。
这项慢性手部疾病的可行性研究表明，三维打印矫形器在活动表现、手部功能和生活质量方面与传统矫形器相似。满意度以及制作时间和成本方面，三维打印手部矫形器更具优势。
