Reliability and validity of the closed kinetic chain upper extremity stability test

Abstract

[Purpose] The purpose of this study was to examine the reliability and validity of the Closed Kinetic Chain Upper Extremity Stability (CKCUES) test. [Subjects and Methods] A sample of 40 subjects (20 males, 20 females) with and without pain in the upper limbs was recruited. The subjects were tested twice, three days apart to assess the reliability of the CKCUES test. The CKCUES test was performed four times, and the average was calculated using the data of the last 3 tests. In order to test the validity of the CKCUES test, peak torque of internal/external shoulder rotation was measured using an isokinetic dynamometer, and maximum grip strength was measured using a hand dynamometer, and their Pearson correlation coefficients with the average values of the CKCUES test were calculated. [Results] The reliability of the CKCUES test was very high (ICC=0.97). The correlations between the CKCUES test and maximum grip strength (r=0.78–0.79), and the peak torque of internal/external shoulder rotation (r=0.87–0.94) were high indicating its validity. [Conclusion] The reliability and validity of the CKCUES test were high. The CKCUES test is expected to be used for clinical tests on upper limb stability at low price.

The Self-Assessment Corner for Shoulder Strength: Reliability, Validity, and Correlations With Upper Extremity Physical Performance Tests

“…Physical performance tests, such as the seated medicine ball throw (SMBT) and the closed kinetic chain upper extremity stability test (CKCUEST), have been developed to assess upper body function and are routinely used on the field for injury prediction, performance assessment, or outcome measures in return-to-play decisions. [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] Although the reliability of these tests has been established, 23,28,[32][33][34][35] comparisons of clinical examinations and PPTs are uncommon. To the best of our knowledge, no investigators have examined the relationship between these PPTs and shoulder ER and IR isometric strength using a self-assessment technique.…”

Inactive individuals with chronic neck pain have changes in range of motion and functional performance of the shoulder

“…Therefore, we recommended the use of these CKCUES scores as measures more consistent with the rehabilitation reality of the patient with neck pain, as compared with the power CKCUES score. However, it is worth noting that each of these three scores is valid and reliable (Tucci et al, ), and the CKCUES test has been used in adolescents (de Oliveira et al, ), individuals with nonspecific pain in the shoulder (Lee & Kim, ), collegiate baseball players (Roush, Kitamura, & Waits, ), and patients with shoulder impingement syndrome (Tucci et al, ).…”

Predictors associated with a range of motion of shoulder rotation in competitive high school water polo players: a cross-sectional study

“…The CKCUES is a reliable and valid performance test that provides quantitative data for an upper limb task in the closed kinetic chain 38 . The test consists of counting the number of times the participants can touch the contralateral supporting hand with their swinging hand, in a push-up position, in 15 seconds.…”
