Shoulder trouble, described in the literature as "swimmer's shoulder," has been associated with competitive swimmers. The Kerlan-Jobe Orthopedic Clinic (KJOC) Shoulder and Elbow Score is a validated survey used to define functional and performance measures of the upper extremity in overhead athletes. To date, no study has investigated the baseline functional scores for swimmers actively competing in the sport.
To establish a baseline score for National Collegiate Athletic Association (NCAA) swimmers actively competing in the sport.
Cross-sectional study; Level of evidence, 3.
After institutional review board approval, the KJOC Shoulder and Elbow Score was administered to 5 NCAA swim teams (N = 99 participants; 46 men, 53 women). The results on 10 specific individual questions and on the total score were calculated according to the survey's original description. The mean scores were calculated for all participants. The Mann-Whitney U test was used to determine differences between sexes, years swimming, and self-reported injury status.
The mean ± SD baseline KJOC score (out of a possible 100) for all participants was 79.0 ± 18.7; the mean score for men was 81.9 ± 15.6 and for women 76.6 ± 20.8. The score for athletes identifying themselves as injured at baseline was 53.9 ± 18.8, compared with 84.4 ± 13.6 for those not reporting as injured (P < .001). Athletes competing ≥11 years had a mean score of 72.0 ± 22.1; those competing ≤10 years scored 86.4 ± 11.4 (P = .007).
Baseline scores for swimmers, which were lower than expected, were lower than baseline scores seen in studies of other overhead sports athletes. The data corroborate previous studies identifying swimmers as having a high level of shoulder trouble. Further research is indicated for improving shoulder symptoms and performance in competitive swimmers.
肩部问题在文献中被描述为“游泳者肩部疾病”，与竞技游泳运动员相关。克尔兰 - 乔布骨科诊所（KJOC）肩部和肘部评分是一项经过验证的调查，用于定义上肢过顶运动运动员的功能和表现指标。迄今为止，尚无研究调查积极参与该项运动的游泳运动员的基线功能评分。
为积极参与该项运动的美国全国大学生体育协会（NCAA）游泳运动员建立基线评分。
横断面研究；证据等级，3级。
经机构审查委员会批准后，对5支NCAA游泳队（N = 99名参与者；46名男性，53名女性）进行KJOC肩部和肘部评分。根据该调查的原始描述计算10个特定单项问题及总分的结果。计算所有参与者的平均得分。采用曼 - 惠特尼U检验来确定性别、游泳年限和自我报告的损伤状况之间的差异。
所有参与者的KJOC基线评分平均值±标准差（满分100分）为79.0±18.7；男性平均分为81.9±15.6，女性为76.6±20.8。在基线时自我认定为受伤的运动员得分为53.9±18.8，而未报告受伤的运动员得分为84.4±13.6（P < 0.001）。参赛≥11年的运动员平均得分为72.0±22.1；参赛≤10年的运动员得分为86.4±11.4（P = 0.007）。
游泳运动员的基线评分低于预期，低于其他上肢过顶运动项目运动员研究中的基线评分。这些数据证实了先前将游泳运动员认定为肩部问题高发人群的研究。有必要开展进一步研究以改善竞技游泳运动员的肩部症状和表现。
