Abstract

Context: Upper-extremity physical performance tests are essential to assess the functional status of athletes. The Closed Kinetic Chain Upper-Extremity Stability Test (CKCUEST) is widely used in sports. However, the psychometric properties of its modified version (MCKCUEST) in swimmers are unknown. We aimed to assess the reliability, standard error of measurement (SEM), minimal detectable change (MDC), and known-group validity of the MCKCUEST in swimmers.

Design: Cross-sectional study.

Methods: We included swimmers of both sexes, aged 12 to 60 years, with and without shoulder pain. Two assessments were conducted with an average interval of 10.37 (3.15) days between them. The MCKCUEST scores were reported as number of touches, normalized score, and power score. Reliability of the MCKCUEST was evaluated using the intraclass correlation coefficient (ICC) (3, 3), SEM, and MDC95. For known-group validity, we compared MCKCUEST scores between swimmers with and without shoulder pain.

Results: Fifty swimmers participated in this study (54% men; 42% with shoulder pain). The MCKCUEST demonstrated excellent reliability (ICC = .90 to .98). The SEM ranged from 1.4 to 1.9 for touches, 5.36 to 7.4 for the power score, and 0.59 to 1.62 for the normalized score. The MDC95 ranged from 4.0 to 5.3 for touches, 11.0 to 20.4 for the power score, and 1.64 to 4.49 for the normalized score. For known-group validity, the asymptomatic group achieved a greater number of touches (mean difference [MD]: 4.5; 95% CI, 0.6-8.4), power score (MD: 23.2; 95% CI, 2.1-44.3), and normalized score (MD: 2.3; 95% CI, 0.03-4.5) than the shoulder pain group.

Conclusion: The MCKCUEST demonstrated excellent reliability for assessing swimmers and adequate known-group validity. The SEM and MDC values observed across all scoring methods were relatively small, indicating low measurement error and the ability of the test to detect meaningful changes in performance over time.

游泳运动员改良封闭式动力链上肢稳定性测试的信度、测量标准误差、最小可检测变化和已知组效度。

背景：上肢体能测试对于评估运动员的功能状态至关重要。闭式运动链上肢稳定性试验（CKCUEST）在体育运动中应用广泛。然而，其修改版本（mccuest）在游泳者中的心理测量特性是未知的。我们旨在评估游泳者MCKCUEST的可靠性、测量标准误差（SEM）、最小可检测变化（MDC）和已知组效度。设计：横断面研究。方法：我们纳入了男女游泳者，年龄12至60岁，有无肩痛。2次评估平均间隔10.37（3.15）天。mccuest得分报告为触摸次数、标准化得分和力量得分。采用类内相关系数（ICC）（3,3）、SEM和MDC95对MCKCUEST的信度进行评估。对于已知组效度，我们比较了有和没有肩痛的游泳者之间的mccuest分数。结果：50名游泳者参与了这项研究（54%为男性，42%为肩痛）。mccuest表现出极好的信度（ICC = 0.90 ~ 0.98）。触摸的扫描电镜（SEM）在1.4到1.9之间，力量得分在5.36到7.4之间，标准化得分在0.59到1.62之间。MDC95的范围从4.0到5.3的触摸，11.0到20.4的力量得分，1.64到4.49的标准化得分。对于已知组效度，无症状组获得了更多的触摸次数（平均差[MD]: 4.5; 95% CI, 0.6-8.4），功率评分（MD: 23.2; 95% CI, 2.1-44.3）和标准化评分（MD: 2.3; 95% CI, 0.03-4.5）比肩痛组。结论：mccuest在评估游泳运动员方面具有良好的信度和足够的已知组效度。在所有评分方法中观察到的SEM和MDC值相对较小，表明测量误差低，并且测试能够检测到性能随时间的有意义的变化。

期刊介绍： The Journal of Sport Rehabilitation (JSR) is your source for the latest peer-reviewed research in the field of sport rehabilitation. All members of the sports-medicine team will benefit from the wealth of important information in each issue. JSR is completely devoted to the rehabilitation of sport and exercise injuries, regardless of the age, gender, sport ability, level of fitness, or health status of the participant. JSR publishes peer-reviewed original research, systematic reviews/meta-analyses, critically appraised topics (CATs), case studies/series, and technical reports that directly affect the management and rehabilitation of injuries incurred during sport-related activities, irrespective of the individual’s age, gender, sport ability, level of fitness, or health status. The journal is intended to provide an international, multidisciplinary forum to serve the needs of all members of the sports medicine team, including athletic trainers/therapists, sport physical therapists/physiotherapists, sports medicine physicians, and other health care and medical professionals.
