■与肱骨后扭转(HRT)校正的旋转ROM相比,旋转运动范围(ROM)的差异存在于健康的棒球运动员中,但目前尚不清楚这些差异是否存在于病理人群中。
■这项研究的目的是确定在受伤的棒球运动员中客观测量的ROM和HRT校正的缺陷之间是否存在差异。据推测,(1)肱骨外旋(GER)和HRT校正的肱骨外旋缺陷(GERD)之间存在差异,(2)肱骨内旋(GIR)和HRT校正的肱骨内旋缺陷(GIRD)之间存在差异。
■横断面研究;证据水平,3.
■来自172名肩膀或肘部受伤的棒球运动员的数据(45名肩膀,127肘)在2023年7月进行了审查。GER和GIR在所有球员的受伤和非受伤方面进行了测量,诊断超声用于测量HRT。进行依赖t检验,以比较GER和GIR与HRT校正的GERD和GIRD的侧向差异,分别。
■在肩伤的球员中,GER的左右差异与HRT校正的GERD之间存在显着差异(2°±14°vs-13°±15°,分别)以及GIR的左右差异与HRT校正的GIRD之间(-14°±8°vs2°±9°,分别)(两者P<.001)。同样,肘部受伤的球员在GER的左右差异与HRT校正的GERD之间存在显着差异(6°±9°vs-10°±9°,分别)以及GIR的左右差异与HRT校正的GIRD之间(-12°±8°vs4°±10°,分别)(两者P<.001)。
■结果支持我们的假设,即在受伤的棒球运动员中,客观测量的GER和GIR差异与HRT校正的GERD和GIRD之间存在差异。在评估和治疗该人群时,必须考虑在肱骨关节发生的骨适应。
UNASSIGNED: Differences in rotational range of motion (ROM) compared to humeral retrotorsion (HRT)-corrected rotational ROM exist in healthy
baseball athletes, but it is unclear whether these differences exist in a pathological population.
UNASSIGNED: The purpose of this study was to determine if there are disparities between objectively measured differences in ROM and HRT-corrected deficits in injured
baseball players. It was hypothesized that disparities would exist between (1) the side-to-side difference in glenohumeral external rotation (GER) and the HRT-corrected glenohumeral external rotation deficit (GERD) and (2) the side-to-side difference in glenohumeral internal rotation (GIR) and the HRT-corrected glenohumeral internal rotation deficit (GIRD).
UNASSIGNED: Cross-sectional study; Level of evidence, 3.
UNASSIGNED: Data from 172
baseball players with shoulder or elbow injuries (45 shoulder, 127 elbow) were reviewed in July 2023. GER and GIR were measured on the injured and noninjured sides of all players, and diagnostic ultrasound was used to measure HRT. Dependent t tests were run to compare the side-to side differences in GER and GIR with the HRT-corrected GERD and GIRD, respectively.
UNASSIGNED: In the players with a shoulder injury, there was a significant disparity between the side-to-side difference in GER and the HRT-corrected GERD (2°± 14° vs -13°± 15°, respectively) and between the side-to-side difference in GIR and the HRT-corrected GIRD (-14°± 8° vs 2°± 9°, respectively) (P < .001 for both). Similarly, players with an elbow injury had significant disparities between the side-to-side difference in GER and the HRT-corrected GERD (6°± 9° vs -10°± 9°, respectively) and between the side-to-side difference in GIR and the HRT-corrected GIRD (-12°± 8° vs 4°± 10°, respectively) (P < .001 for both).
UNASSIGNED: The results supported our hypothesis that there were disparities between objectively measured differences in GER and GIR compared with the HRT-corrected GERD and GIRD in injured
baseball players. Consideration must be given to osseous adaptations that occur at the glenohumeral joint when evaluating and treating this population.
