Background: The 6 min pegboard and ring test (6PBRT) is a valid and reproducible test of unsupported arm exercise endurance. The aim of this study was to determine the associations between the 6PBRT, activities of daily living (ADL) and hemoglobin levels in chronic obstructive pulmonary disease (COPD).

Methods: This study included 40 stable patients with COPD. All participants underwent the 6PBRT, peripheral venous blood sampling, arm ergometer test and the Glittre-ADL and ADL simulation tests for the ADLs performance.

Results: An average 172.51 ± 25.94 rings were moved in 6 min. The number of rings in 6PBRT was significantly positively correlated with the number of cycles in ADL simulation test (r = 0.553, p < 0.001), peak oxygen consumption in arm ergometer (r = 0.381, p = 0.024) and serum hemoglobin level (r = 0.411, p = 0.011).

Conclusion: The number of rings moved in the 6PBRT is associated with ADL simulation test performance that reflects upper extremity ADLs. Therefore, the 6PBRT can be used for estimating limitation in upper extremity ADLs as a simple and quick evaluation in patients with GOLD stage II-III COPD.
