BACKGROUND/HYPOTHESIS: Nontraumatic shoulder pain is a prevalent issue among male high school volleyball players, yet prior research has often limited its assessment to isolated aspects of shoulder function. This study aimed to identify contributing factors to shoulder pain in this population. We hypothesized that limited shoulder internal rotation (IR) range of motion (ROM), imbalance in rotator cuff muscle strength, intrinsic sensory disturbance, and joint stability are associated with shoulder pain in male high school volleyball players. Additionally, we anticipated that a substantial proportion of players would experience shoulder pain but refrain from reporting it to coaches.
Forty-nine male volleyball players aged 15-17 years were evaluated between February and June 2023. Questionnaires assessed the prevalence of shoulder pain during spiking and/or serving and the frequency of reporting this pain to coaches. Factors such as acromio-humeral distance, shoulder passive ROM, isometric strength, proprioception, joint stability (Upper Quarter Y-Balance Test), joint position sense, and upper extremity power (Seated Medicine Ball Throw Test) were quantified. Logistic regression analyses were conducted to explore associations between these variables and shoulder pain.
Shoulder pain was reported by 39% of participants, with only 5% communicating it to coaches. Jump serves (odds ratio 1.84, P = .02) and reduced shoulder IR ROM (odds ratio 0.94, P = .03) were associated with shoulder pain.
This study provides critical insights into the prevalence, severity, and factors associated with shoulder pain among male high school volleyball players. The findings underscore the importance of improving athlete-coach communication for early intervention and prevention. Significant associations between jump serves, reduced shoulder IR ROM, and shoulder pain highlight the role of specific volleyball techniques in injury prevention, offering valuable guidance for coaches and trainers in developing targeted interventions to mitigate shoulder pain and enhance player performance.
背景/假设：非创伤性肩部疼痛在男性高中排球运动员中是一个普遍问题，但先前的研究往往将其评估局限于肩部功能的孤立方面。本研究旨在确定该人群肩部疼痛的促成因素。我们假设，肩部内旋（IR）活动范围（ROM）受限、肩袖肌群力量失衡、内在感觉障碍和关节稳定性与男性高中排球运动员的肩部疼痛有关。此外，我们预计很大一部分运动员会经历肩部疼痛，但不会向教练报告。
2023年2月至6月对49名年龄在15 - 17岁的男性排球运动员进行了评估。问卷调查评估了扣球和/或发球时肩部疼痛的患病率以及向教练报告这种疼痛的频率。对肩峰 - 肱骨距离、肩部被动ROM、等长力量、本体感觉、关节稳定性（上肢Y平衡测试）、关节位置觉和上肢力量（坐姿药球投掷测试）等因素进行了量化。进行逻辑回归分析以探讨这些变量与肩部疼痛之间的关联。
39%的参与者报告有肩部疼痛，其中只有5%告知了教练。跳发球（优势比1.84，P = 0.02）和肩部IR ROM降低（优势比0.94，P = 0.03）与肩部疼痛有关。
本研究为男性高中排球运动员肩部疼痛的患病率、严重程度及相关因素提供了重要见解。研究结果强调了改善运动员与教练沟通以进行早期干预和预防的重要性。跳发球、肩部IR ROM降低与肩部疼痛之间的显著关联凸显了特定排球技术在预防损伤中的作用，为教练和训练师制定有针对性的干预措施以减轻肩部疼痛并提高运动员表现提供了有价值的指导。
