Objective: Despite the studies that have investigated the reliability of Upper Extremity Functional Tests(UEFTs), the reliability of Closed Kinetic Chain Upper Extremity Stability(CKCUES), Seated Medicine Ball Throw(SMBT), push-up(PU) and Unilateral Seated Shot Put(USSP) tests in overhead athletes has yet to be assessed. The objective of this study was to determine both the relative and absolute test-retest reliability of the four UEFTs in female overhead athletes.
Methods: Twenty-nine female overhead athletes (age: 26.6 ± 5.29 years) underwent the four UEFTs twice within a three- day interval. The upper limb stability was assessed through PU and CKCUES tests, while the power was assessed though SMBT and USSP tests. The Intraclass Correlation of Coefficient (ICC) was applied to assess the relative reliability. Absolute reliability was determined by calculating the Standard Error of Measurement (SEM) and the Minimal Detectable Change (MDC). Furthermore, Bland-Altman plots were used to detect the agreements between the two measurements.
Results: The relative reliability of PU, CKCUES, SMBT, and non-dominant arm USSP tests was excellent (ICC = 0.83, 0.80, 0.91, and 0.83, respectively). SEM was within a range of 1.69 to 1.72 for stability tests and a range of 13.61 to 52.12 for power (based on a 95% confidence interval). The MDC was 4.68 for PU and 4.75 for CKCUES test. At least four repetitions are needed to be considered a real improvement on PU and CKCUES tests. This value was 144.04, in SMBT and 59.03, 37.62 cm (dominant and non-dominant arm, respectively) in USSP tests, which represents the minimum change that must occur to be considered an athlete's progression.
Conclusion: This study revealed that both the upper limb stability and power tests have acceptable relative and absolute intra-rater reliability in female overhead athletes. These can be considered as reliable tools in research and clinical settings.
