Test-Retest Reliability of the Closed Kinetic Chain upper Extremity Stability Test in Children Aged 7-10 Years

Abstract

The aim of this study is to investigate the test-retest reliability of the Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST) and modified-CKCUEST in children aged 7-10 years and to compare the two test versions within the same group. The study was completed with fifty-three children. Average, normalized, and power scores were obtained from the maximum number of touches in 15 x 3 s in the tests. Tests were repeated seven days apart for test-retest reliability. Intraclass Correlation Coefficient (ICC3,1), Standard Error of Measurement (SEM), Minimum Detectable Change (MDC) were tested total/by gender. Children's opinions about the tests were questioned. The test-retest ICC3,1 values for CKCUEST were 0.96 for average score, 0.95 for normalized score, 0.97 for power score. For the modified-CKCUEST, test-retest reliabilities were 0.94, 0.92, 0.96, respectively. CKCUEST and modified-CKCUEST demonstrated excellent test-retest reliability for children aged 7-10 years. Participants stated that the modified-CKCUEST was more suitable as a test position.
