Shoulder pain is becoming increasingly problematic in young players as volleyball gains popularity. Associations between repetitive motion and pain and overuse injury have been observed in other overhand sports (most notably baseball). Studies of adult athletes suggest that there is a shoulder pain and overuse problem present in volleyball players, but minimal research has been done to establish rates and causes in juvenile participants.
To establish rates of shoulder pain, regardless of whether it resulted in a loss of playing time, in female high school volleyball players. A secondary goal was to determine whether high repetition volumes correlated with an increased likelihood of experiencing pain.
Descriptive epidemiology study.
A self-report survey focusing on the prevalence of pain not associated with a traumatic event in female high school youth volleyball players was developed. Survey questions were formulated by certified athletic trainers, experienced volleyball coaches, and biomechanics experts. Surveys were received from 175 healthy, active high school volleyball players in Iowa, South Dakota, and Minnesota.
Forty percent (70/175) of active high school volleyball players remembered experiencing shoulder pain not related to traumatic injury, but only 33% (23/70) reported taking time off to recover from the pain. Based on these self-reported data, activities associated with significantly increased risk of nontraumatic shoulder pain included number of years playing competitive volleyball ( = .01) and lifting weights out of season ( = .001). Players who reported multiple risk factors were more likely to experience nontraumatic shoulder pain.
When using time off for recovery as the primary injury criterion, we found that the incidence of shoulder pain is more than twice as high as the incidence of injury reported by previous studies. Findings also indicated that the incidence of shoulder pain may be correlated with volume of previous volleyball experience.
随着排球运动日益普及，肩部疼痛在年轻运动员中成为越来越严重的问题。在其他上肢运动（最显著的是棒球）中，已观察到重复动作与疼痛及过度使用损伤之间的关联。对成年运动员的研究表明，排球运动员存在肩部疼痛和过度使用问题，但在青少年参与者中确定发病率和病因的研究极少。
确定高中女子排球运动员肩部疼痛的发病率，无论其是否导致比赛时间减少。第二个目标是确定高重复量是否与疼痛发生的可能性增加相关。
描述性流行病学研究。
针对高中女子青少年排球运动员中与创伤事件无关的疼痛患病率开展了一项自我报告调查。调查问卷由认证运动训练师、经验丰富的排球教练和生物力学专家制定。从爱荷华州、南达科他州和明尼苏达州的175名健康、活跃的高中排球运动员那里收到了调查问卷。
40%（70/175）的活跃高中排球运动员记得经历过与创伤性损伤无关的肩部疼痛，但只有33%（23/70）报告因疼痛而请假恢复。基于这些自我报告的数据，与非创伤性肩部疼痛风险显著增加相关的活动包括参加竞技排球比赛的年数（P = 0.01）和在非赛季举重（P = 0.001）。报告有多种风险因素的运动员更有可能经历非创伤性肩部疼痛。
当以请假恢复作为主要损伤标准时，我们发现肩部疼痛的发病率比先前研究报告的损伤发病率高出两倍多。研究结果还表明，肩部疼痛的发病率可能与之前排球运动经历的时长相关。
