| Summary: | Background: The CKCUES test evaluates the functional performance of the shoulder joint.
The CKCUES test scores CKC exercises of the upper limbs to examine shoulder stability. Although
the CKCUES test provides quantitative data on functional ability and performance,
no study has determined the relationship between CKCUES scores and SA and TB muscle
strength.
Objects: The objective of this study is to determine the relationship between the CKCUES test
scores and the strength of the SA and TB muscles in the CKCUES and unilateral CKCUES tests.
Methods: Sixty-six healthy male volunteers participated in the study. A Smart KEMA strength
sensor measured SA and TB muscle strength. Two parallel lines on the floor indicated the
initial hand placement to start CKCUES tests. For 15 seconds, the subject raises one hand and
reaches over to touch the supporting hand, then returns to the starting position.
Results: The correlation between the CKCUES test scores and the strength of the SA was
strong (r = 0.650, p < 0.001), and the TB was moderate (r = 0.438, p < 0.001). The correlation
between the unilateral CKCUES test and the strength of the SA of the supporting side was
strong (r = 0.605, p < 0.001), and swing side was strong (r = 0.681, p < 0.001). The correlation
between the unilateral CKCUES test and the strength of the TB of the supporting side
was moderate (r = 0.409, p < 0.001), and swing side was moderate (r = 0.482, p < 0.001).
Conclusion: Our study showed that the CKCUES test had a strong association with isometric
strength of SA and moderate association with that of TB. These findings suggest that the
CKCUES test can evaluate the function of the SA. Moreover, the unilateral CKCUES test can
evaluate unilateral shoulder function. |
