“…Among them, a total of 22 were selected , excluding articles that did not match the inclusion criteria (Figure 1). Of the 22 studies, there were 8 studies related to the upper limbs (6,11,(16)(17)(18)(19)21,24), 13 related to the lower limbs (3)(4)(5)(7)(8)(9)(10)12,14,15,20,22,23), and 1 related to the spine (13).…”

“…The evaluation criteria are as follows: (I) level 1: systematic reviews and meta-analysis of randomized controlled trials (RCTs), (II) level 2: one or more RCTs, (III) level 3: controlled trials without randomization (at least two groups), (IV) level 4: case-control or cohort study, (V) level 5: systematic review of descriptive and qualitative study, (VI) level 6: single descriptive or qualitative study, and (VII) level 7: expert opinion. The results of the level of evidence evaluation of the papers included in this review were level 2 in six papers (6)(7)(8)(9)(10)(11), level 3 in six papers (4,5,(12)(13)(14)(15), and level 4 in ten papers (3,(16)(17)(18)(19)(20)(21)(22)(23)(24).…”

“…The shape of the insole was similar to that of a ready-made insole. In 2019, Mo et al (8) produced a 3D printed foot orthosis, with the subtalar joint positioned neutrally. A 3-mm PORON cover was added to the foot orthosis.…”

Recently, three-dimensional (3D) printing technology has gradually been applied to the field of orthoses. This narrative review aimed to investigate the effect of 3D printed orthoses compared to conventional orthoses (non-3D printed orthoses). We searched MEDLINE for articles published up to July 27, 2020, and the main search phrases for identifying related articles were "3D printed orthosis", "3D printed orthoses", "3D printed braces", "3D printed splints", "3D printing orthosis", "3D printed orthoses", "3D printing braces" and "3D printing splints". We included articles that applied 3D printed orthoses to patients or healthy participants and excluded those not written in English, conference abstracts or presentations, and reviews. A total of 237 papers were identified, and qualifications were evaluated based on the title, abstract, and full text. A total of 22 articles were finally included in the analysis. The 3D printed orthoses showed similar or superior effects on biomechanical parameters and kinematic parameters such as wrist-hand function, wrist spasticity, arch height index, foot plantar pressure, and joint range of motion (ROM). In addition, 3D printed orthoses had high satisfaction and comfort compared to conventional orthoses. We believe that 3D printed orthoses can replace conventional ones, and they are expected to gain more popularity in the future.

Advances in Orthotic and Prosthetic Manufacturing: A Technology Review

et al. 2020

View full text Add to dashboard Cite

In this work, the recent advances for rapid prototyping in the orthoprosthetic industry are presented. Specifically, the manufacturing process of orthoprosthetic aids are analysed, as thier use is widely extended in orthopedic surgery. These devices are devoted to either correct posture or movement (orthosis) or to substitute a body segment (prosthesis) while maintaining functionality. The manufacturing process is traditionally mainly hand-crafted: The subject’s morphology is taken by means of plaster molds, and the manufacture is performed individually, by adjusting the prototype over the subject. This industry has incorporated computer aided design (CAD), computed aided engineering (CAE) and computed aided manufacturing (CAM) tools; however, the true revolution is the result of the application of rapid prototyping technologies (RPT). Techniques such as fused deposition modelling (FDM), selective laser sintering (SLS), laminated object manufacturing (LOM), and 3D printing (3DP) are some examples of the available methodologies in the manufacturing industry that, step by step, are being included in the rehabilitation engineering market—an engineering field with growth and prospects in the coming years. In this work we analyse different methodologies for additive manufacturing along with the principal methods for collecting 3D body shapes and their application in the manufacturing of functional devices for rehabilitation purposes such as splints, ankle-foot orthoses, or arm prostheses.

“…Suppressing the calcaneal eversion was believed to be the most important function achieved by orthotic insoles [31]. The 3D printed insoles fabricated by Mo, et al [32] and Telfer, et al [33] also demonstrated a significant reduction in peak hindfoot eversion. Our study found no significant change but a slight trend of reduction on the hindfoot eversion and forefoot abduction.…”

A Three-Dimensional Printed Foot Orthosis for Flexible Flatfoot: An Exploratory Biomechanical Study on Arch Support Reinforcement and Undercut

et al. 2021

The advancement of 3D printing and scanning technology enables the digitalization and customization of foot orthosis with better accuracy. However, customized insoles require rectification to direct control and/or correct foot deformity, particularly flatfoot. In this exploratory study, we aimed at two design rectification features (arch stiffness and arch height) using three sets of customized 3D-printed arch support insoles (R+U+, R+U−, and R−U+). The arch support stiffness could be with or without reinforcement (R+/−) and the arch height may or may not have an additional elevation, undercutting (U+/−), which were compared to the control (no insole). Ten collegiate participants (four males and six females) with flexible flatfoot were recruited for gait analysis on foot kinematics, vertical ground reaction force, and plantar pressure parameters. A randomized crossover trial was conducted on the four conditions and analyzed using the Friedman test with pairwise Wilcoxon signed-rank test. Compared to the control, there were significant increases in peak ankle dorsiflexion and peak pressure at the medial midfoot region, accompanied by a significant reduction in peak pressure at the hindfoot region for the insole conditions. In addition, the insoles tended to control hindfoot eversion and forefoot abduction though the effects were not significant. An insole with stronger support features (R+U+) did not necessarily produce more favorable outcomes, probably due to over-cutting or impingement. The outcome of this study provides additional data to assist the design rectification process. Future studies should consider a larger sample size with stratified flatfoot features and covariating ankle flexibility while incorporating more design features, particularly medial insole postings.
