Abstract
[Purpose] The aim of this study was to elucidate the usefulness of the 30-second chair stand test (CS-30) for evaluating the exercise capacity of patients with mild to moderate interstitial pneumonia (IP). [Subjects and Method] Nineteen consecutive patients who performed the 6-minute walk test (6MWT) and the CS-30 as evaluations in clinical practice were enrolled. The results of the 6MWT and CS-30 were compared. [Results] The number of chair stands significantly correlated with the 6-minute walk distance. It also showed significant correlations with the maximum heart rate, maximum respiratory rate, and maximum modified Borg dyspnea score, and these items’ values were significantly lower in the CS-30. A significant correlation with minimum SpO2 was also found, and the decrease in SpO2 was significantly smaller in the CS-30. [Conclusion] The results suggest that CS-30 correlates well with 6MWT and can be performed with lower risk of desaturation in patients with mild to moderate IP.
