Brief summary

It becomes important to evaluate closed kinetic chain activity. The aim of this study was to develop and to determine the test-retest, intra- and interreliability, and validity of the Closed Kinetic Chain Lower Extremity Stability Test (CKCLEST).

Detailed description

Closed kinetic chain activities and exercises are used more and more in rehabilitation programs as they take place in daily life as functional movements. Therefore, it becomes important to evaluate closed kinetic chain activity. The aim of this study is to develop and to determine the test-retest, intra- and interreliability, and validity of the Closed Kinetic Chain Lower Extremity Stability Test (CKCLEST). Three-blinded, cross-sectional, repeated-measures clinical measurement reliability trial. To assess the reliability of CKCLEST, intraclass correlation coefficient (ICC), standard error of measurement (SEM), minimal detectable change (MDC), and Bland-Altman plot will be used. For concurrent validity of CKCLEST will be applied Spearman correlation analysis with Vertical Jump Test, Isokinetic Dynamometer Test, Single Leg Hop Test, and Prone Bridge Test. All analyses were made for both the best score and the average score. This test allows the evaluation of functional lower extremity stability, static/dynamic control of the lower extremity (knee/hip) or trunk, and simultaneous activation of the quadriceps and hamstring muscles / such coactivation.
