The Upper Limb Orthosis in the Rehabilitation of Stroke Patients: The Role of 3D Printing

The effectiveness of 3d printing technology course on attitudes of occupational therapy students-a controlled study

There is interest in three-dimensional (3D) printing technology, but views on the integration of these technologies into business and education vary. It is crucial to determine how the introduction of new technologies will impact the attitudes of occupational therapy undergraduate students. Hence, the purpose of this study is to examine the effect of using this technology in the assistive technology (AT) lesson on the attitudes and acceptance of technology among students. This study was designed as a non-randomized controlled pretest and posttest control group study. The intervention group consisted of second-year undergraduate students (n = 50) enrolled in a compulsory "AT course," while the control group consisted of third-year undergraduate students (n = 41) who had completed the AT course in the previous academic year. The intervention involved participants attending a 3D printing course in combination with an 8-week AT course. A Modified Technology Acceptance Model (M-TAM) questionnaire was used to assess students' acceptance of 3D printing technology. The related study observed that experiencing and practicing new technologies, such as 3D printing and modeling course in the intervention group AT lesson effectively increased the acceptability of these new technologies that students encountered. The pre-post test analysis of the intervention group was statistically significant in all categories of the M-TAM questionnaire (p < 0.05). Compared to the control group, the effect size was small and moderate in all categories (p < 0.05). This course has increased student acceptance of this technology. Future studies should examine the long-term effects of such courses on student attitudes.

Surgical Medical Education via 3D Bioprinting: Modular System for Endovascular Training

There is currently a shift in surgical training from traditional methods to simulation-based approaches, recognizing the necessity of more effective and controlled learning environments. This study introduces a completely new 3D-printed modular system for endovascular surgery training (M-SET), developed to allow various difficulty levels. Its design was based on computed tomography angiographies from real patient data with femoro-popliteal lesions. The study aimed to explore the integration of simulation training via a 3D model into the surgical training curriculum and its effect on their performance. Our preliminary study included 12 volunteer trainees randomized 1:1 into the standard simulation (SS) group (3 stepwise difficulty training sessions) and the random simulation (RS) group (random difficulty of the M-SET). A senior surgeon evaluated and timed the final training session. Feedback reports were assessed through the Student Satisfaction and Self-Confidence in Learning Scale. The SS group completed the training sessions in about half time (23.13 ± 9.2 min vs. 44.6 ± 12.8 min). Trainees expressed high satisfaction with the training program supported by the M-SET. Our 3D-printed modular training model meets the current need for new endovascular training approaches, offering a customizable, accessible, and effective simulation-based educational program with the aim of reducing the time required to reach a high level of practical skills.
