“…Many aspects such as design, function, comfort, and appearance impact orthotic treatment outcomes. Several studies have shown that 3D-printed orthoses are often comparable and occasionally even more effective than traditional orthotics in terms of fabrication process, comfort/fit, and functionality (Oud et al, 2021, Portnova et al, 2018, Toth et al, 2020, Zheng et al, 2020.…”

“…Instability of the joint may result in direct injuries, including bone fractures, dislocation of joints, and/or soft tissue injuries such as muscle strains or ligaments sprains. Impairments of the hand and wrist can occur in neurological, neuromuscular, and musculoskeletal disorders (Althoff & Reeves, 2020;Oud et al, 2021). Examples of common chronic conditions within these categories include spinal cord injuries (SCI), multiple sclerosis (MS), cerebral palsy (CP), and cerebrovascular accidents (CVA).…”

“…The process of fabricating a conventional orthosis can pose several problems. Fabrication of the conventional thermoplastic hand and wrist orthosis can be laborious, time-consuming, and prone to extensive production time, mixed functional outcomes, and lead to decreased satisfaction due to inaccuracy of fit and discomfort (Oud et al, 2021). Conventional hand-made orthoses cannot fully match the curve of the wrist and hand.…”

“…An emerging alternative is the potential use of three-dimensional (3D) scanning of the contours of the body, paired with 3D printing or orthoses. This technology has the potential to contribute improvements in orthoses fabrication accuracy (Oud et al, 2021;Portnova et al, 2018;Toth et al, 2020;Zheng et al, 2020). The purpose of the present research study was to compare the differences in comfort, fabrication, and functionality between 3D-printed and conventional hand orthoses.…”

Traditional methods of custom orthosis fabrication are prone to challenges and limitations. Three-dimensional (3D) printing has been piloted with lower extremity orthotics and worthy of exploration with upper extremities. The aim of this study was to compare three-dimensionally printed wrist immobilization splints to conventionally made orthoses in terms of fabrication, comfort, and functionality. Three healthy participants with no history of wrist or hand conditions were recruited to be fitted for conventional and 3D-printed wrist immobilization splints. A sequential mixed-methods study design was conducted to explore comfort, fabrication, and functionality. An ethnographic study was conducted afterward to further understand the fabrication process of 3D-printed orthotics. The Quebec User Evaluation of Satisfaction with Assistive Technology and a Splint Analysis form was used to assess comfort. The function was assessed using the Jebsen-Taylor Hand Function Test. A five-point satisfaction Likert scale was used to evaluate fabrication. Although the results were not statistically significant due to the small sample size, 3D-printed orthotics appear to provide some benefits over traditional methods.

IntroductionHand orthoses are often provided to improve performance of activities of daily life (ADL). Yet, the manufacturing process of conventional custom-fabricated hand orthoses is a time-consuming and labour-intensive process. Even though three-dimensional (3D) printing of orthoses is a rapidly growing area that can facilitate the manufacturing process of hand orthoses, evidence on the effectiveness, costs and production time of 3D-printed orthoses in chronic hand conditions is scarce. This study aims to assess (1) the preliminary effectiveness of 3D-printed orthoses compared with conventionally custom-fabricated orthoses in persons with chronic hand conditions, (2) production time and costs of both orthoses and (3) experiences of the participants and orthotists with the manufacturing process of the 3D-printed orthosis.Methods and analysisIn this prospective non-randomised interventional feasibility study, 20 adults with various chronic hand conditions using a conventional thumb, wrist or wrist-thumb orthosis will be provided with a 3D-printed corresponding type of orthosis. Assessments will be done 2 weeks prior to the intervention and at baseline for the conventional orthosis, and at 1 month and 4 months follow-up for the 3D-printed orthosis. The primary outcome is change from baseline in ADL performance (custom short form Dutch-Flemish Patient-Reported Outcomes Measurement Information System-Upper Extremity; ADL domain Michigan Hand Outcomes Questionnaire Dutch language version (MHQ-DLV)) at 4 months follow-up. Secondary outcomes include general hand function (MHQ-DLV), satisfaction with the orthosis (Dutch Client Satisfaction with Device; Dutch version of the Quebec User Evaluation of Satisfaction with Assistive Technology), usability (in-house questionnaire) and quality of life (EuroQoL 5-Dimension 5-Level). Costs and production time of the conventional and 3D-printed orthoses will be prospectively recorded. Experiences regarding the manufacturing process will be obtained from participants and orthotists (in-house questionnaire).Ethics and disseminationThe Medical Ethics Committee of the Amsterdam UMC, Academic Medical Centre, has waived the requirement for ethical review of this study. Results will be disseminated through peer-reviewed journals, scientific conferences, and media aimed at a broad audience including patients.Trial registration numberNCT05320211.

Objective: 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. Design: Interventional feasibility study. Subjects: Chronic hand orthotic users (n = 21). Methods: 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. Results: 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. Conclusions: 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.
