Purpose: To examine the relationship between performance

on the Closed Kinetic Chain Upper Extremity Stability Test

(CKCUEST) and the Posterior Shoulder Endurance Test in healthy

young adults.

Methods: Twenty healthy young adults (11 female, 9 male;

mean age: 20.75±1.71 years; height: 1.73±0.08 m; BMI:

24.77±4.32 kg/m²) were classified as active (n=11) or sedentary

(n=9) using the IPAQ-SF. All participants completed the CKCUEST

and Posterior Shoulder Endurance Test. Correlations between

endurance test time and CKCUEST performance were analyzed

using Spearman’s rho.

Results: Significant correlations were found between CKCUEST

performance and endurance test time in both limbs (left:

r=0.661, p<0.001; right: r=0.838, p<0.001). Physically active

individuals performed better on all outcomes. Stronger

correlations were observed in the sedentary group (left:

r=0.683, p=0.042; right: r=0.700, p=0.036) compared to the

active group (left: r=0.391, p=0.235; right: r=0.805, p=0.003).

Conclusion: Performance on the CKCUEST is strongly correlated

with Posterior Shoulder Endurance Test results in both

sedentary and active individuals. These tests are applicable for

assessing upper extremity performance across activity levels.
