Title: Satisfaction with customizable 3D-printed finger orthoses compared to commercial finger orthoses

Abstract

Introduction: Emerging research in rehabilitation/occupational therapy primarily supports 3D-printing as a low-cost, customizable option for prosthetics and adaptive equipment. However, more research is necessary to inform clinicians of its use for orthoses. Purpose of the Study: (1) To develop a visually attractive 3D-printed anti-swan neck finger orthosis design that can be adjusted, customized, and manufactured quickly, easily, and cost-effectively (Figure 1), (2) To assess orthotic users’ satisfaction with customizable 3D- printed finger orthoses compared to commercial finger orthoses. Methods: Forty persons without prior upper extremity conditions were recruited at an academic medical center in the United States. After wearing each orthosis for 8 hours (or as long as tolerated), participants completed post-satisfaction surveys to measure satisfaction with different aspects of both orthoses worn. Results: Forty participants (21 females, 19 males, mean age = 24.98 years) were enrolled in the study. Satisfaction scores (N=40) were not statistically significant for 3D-printed orthoses compared to SilverRing™ Splints across all domains except for Affordability, which was rated significantly higher for 3D-printed orthoses (M = 10.00, SD = 0.000) compared to SilverRing™ Splints (M = 5.28, SD = 2.35), t(39) = 12.70, p < .001. The mean difference in satisfaction scores was 4.72, with a 95% confidence interval ranging from 3.97 to 5.48 and large effect size (r = .90). Conclusions: Findings provide novel evidence supporting the use of this customizable 3D-printed prototype as a cost-effective, alternative option (~$0.10) to established commercial finger orthoses. This study has potential to assist clinicians’ decision-making as they navigate best orthoses options for individuals with rheumatoid arthritis and swan neck deformities while considering orthotic wear compliance and client satisfaction.
