Functional tests could be considered a valuable complementary low-cost clinical tool to provide quantitative data about the functional ability and performance of a body segment. Thus, shoulder evaluation could be improved by including techniques those assess functional movements and biomechanical impairment present in professional or daily life activities. Results suggest CKCUES Test is a reliable tool to evaluate upper extremity functional performance for sedentary, for upper extremity sport specific recreational, and for sedentary males and females with SIS.Ĭommonly, the musculoskeletal physical exam is focused on measures of range of motion (ROM) and muscular strength of the affected segment that could not provide enough information about overall segment functional level of activity. At least three touches are needed to be considered a real improvement on CKCUES Test scores. SEM ranged from 1.45 to 2.76 touches (based on a 95% CI) and MDC ranged from 2.05 to 3.91(based on a 95% CI) in subjects with and without SIS. All scores were greater in active compared to sedentary and SIS males and females. Scores were greater in active compared to sedentary, with exception of power score. Results also showed excellent intrasession reliability of number of touches for all samples. The CKCUES Test showed excellent intersession reliability for scores in all samples. Measurement error was determined by calculating the Standard Error of the Measurement (SEM) and Minimum detectable change (MDC) for all scores. Test scores within groups of same gender also were compared.
Intraclass Correlation Coefficient ICC 2,1 was used to assess intrasession reliability of number of touches score and ICC 2,3 was used to assess intersession reliability of number of touches, normalized score, and power score. The last three repetitions were averaged and used to statistical analysis.
Each subject performed four test repetitions, with 45 seconds of rest between them. Subjects were tested twice, seven days apart. MethodsĪ sample of 108 subjects with and without SIS was recruited. Other purpose was to compare scores within sedentary and within recreational athletes samples of same gender. The purpose was to examine inter and intrasession reliability of CKCUES Test for samples of sedentary male and female with (SIS), for samples of sedentary healthy male and female, and for male and female samples of healthy upper extremity sport specific recreational athletes. However, its reliability was tested only in recreational athletes’ males and there are no studies comparing scores between sedentary and active samples. The Close Kinetic Chain Upper Extremity Stability Test (CKCUES test) is a low cost shoulder functional test that could be considered as a complementary and objective clinical outcome for shoulder performance evaluation.
