Reliability, Standard Error of Measurement, Minimal Detectable Change, and Known-Group Validity of Modified Closed Kinetic Chain Upper-Extremity Stability Test in Swimmers.
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.
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.
