Background and Objectives: Three-dimensional (3D) scanning is increasingly utilized in medical practice, from orthotics to surgical planning. However, traditional hand measurement techniques remain inconsistent and prone to human error and are often time-consuming. This research evaluates the practicality of a commercial 3D scanning method by comparing the accuracy of scans conducted by two user groups. Materials and Methods: This study evaluated the following two groups: an experimental group (n = 45) and a control group (n = 42). A total of 261 hand scans were captured using the Structure Sensor Pro 3D scanner for iPad (Structure, Boulder, CO, USA). The scans were then evaluated using Meshmixer software (version 3.5.474), analyzing key parameters, such as surface area, volume, number of vertices, and triangles, etc. Furthermore, a digital literacy test and a user experience survey were conducted to support a more comprehensive evaluation of participant performance within the study. Results: The experimental group outperformed the control group on all measured parameters, including surface area, volume, vertices, triangle, and gap count, with large effect sizes observed. User experience data revealed that participants in the experimental group rated the 3D scanner significantly higher across all dimensions, particularly in ease of use, excitement, supportiveness, and practicality. Conclusions: A short 15 min training session can promote scan reliability, demonstrating that even minimal instruction improves users’ proficiency in 3D scanning, fundamental for supporting clinical accuracy in diagnosis, surgical planning, and personalized device manufacturing

Coaching leadership is experienced through both subjective perceptions and observable actions, but these sources do not represent equivalent constructs. This descriptive multi-case study examined coach–athlete perceptual alignment and match-observed behaviors in four elite youth soccer coach–team cases. Four male youth soccer coaches and 64 male athletes (14–18 years) from a single Romanian elite soccer academy participated in the study. Athletes completed the Multidimensional Scale of Leadership in Sport (MSLS) before and after an official match; each coach completed one post-match self-rating referring to that match. Each coach was compared only with his corresponding team’s post-match mean. Dimension-specific discrepancy scores and a mean absolute discrepancy (MAD) index were calculated. Pre–post comparisons used Wilcoxon signed-rank tests with Holm correction. One match per coach was coded descriptively using the Coach Analysis and Intervention System (CAIS). The MAD index was lowest for the U17 case (1.93) and highest for the U18 case (4.35). After Holm correction, post-match scores were lower for Inspiration, Individualization, and Support. Instruction was highly rated in the MSLS and was the most frequent CAIS category in all four matches (25.2–41.6%), representing a parallel descriptive pattern rather than formal agreement. The findings are specific to four coach–team cases and provide complementary, preliminary perspectives on perceived and match-observed leadership. The single-match, single-observer design and absence of observational reliability assessment preclude characterization of habitual coaching behavior.
