RESUMO
Background: Differences in the physical characteristics of bilateral and unilateral lumbar bone stress injuries (BSIs) are unknown. Purpose: To compare bilateral and unilateral lumbar BSIs in adolescent male soccer players, with a focus on lumbopelvic alignment. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 78 players (age range, 12-15 years) from a local soccer club who had magnetic resonance imaging (MRI) evaluations were included in the study. Lumbopelvic alignment and lumbar BSI were evaluated using short-tau inversion recovery and 3-dimensional LAVA on 3-T MRI; lumbar BSI was defined as the presence of bone marrow edema and/or the complete and incomplete fracture in the pars region on the MRI. Pelvic tilt (PT) and pelvic outflare angles were assessed on the kicking and pivoting sides, and asymmetry for each parameter was calculated by subtracting the kicking side from the pivoting side. In addition, the lumbar lordosis (LL), sacral slope (SS), and SS relative to LL (calculated by subtracting LL from the SS) were assessed. One-way analysis of variance was performed to compare lumbopelvic alignment in players with bilateral BSI, unilateral BSI, or no abnormal findings (controls). Results: No significant differences were found regarding lumbopelvic alignment between the players with bilateral versus unilateral lumbar BSI. PT asymmetry was significantly greater in both players with bilateral lumbar BSI and unilateral lumbar BSI compared with controls (P = .018 and P = .016, respectively). In addition, SS relative to LL was significantly greater in players with bilateral lumbar BSI compared with controls (P < .001). Conclusion: Although there were no significant lumbopelvic alignment differences between bilateral and unilateral BSI, players with bilateral BSI exhibited increased sacral anterior tilt relative to the LL, and the pelvis was more posterior on the pivoting side than on the kicking side in both players with bilateral BSI and unilateral BSI. Our results suggest that lumbopelvic alignment assessment may contribute to the management strategy for players with lumbar BSI and to the identification of players at high risk of lumbar BSI.
RESUMO
[Purpose] The aim of this study was to investigate the development of a database and system for easily creating documents for educational guidance on a personal computer and to assess the efficacy of such a system. [Participants and Methods] Thirty-seven athletic trainers of students who belonged to an athletic department participated in the study. We used FileMaker Pro 17 Advanced for document creation, and data on independent exercises for athletic rehabilitation were used for database creation. The participants created educational documents for the athletic rehabilitation of ankle sprains using paper media and this system. We surveyed the following items and compared them between the groups: 1) time taken to create the documents, 2) difficulty of creating menus for educational coaching, and 3) the potential for ongoing provision of self-training menus. [Results] The preparation times for creating the rehabilitation menu were significantly lower using the database than using paper media. As a result of the questionnaire survey, we found that using the database was significantly better than using paper media in terms of ease of menu creation and the potential for ongoing provision of self-training menus. [Conclusion] Our results suggest that educational coaching for rehabilitation using a database would be valuable for student athletic trainers.
