One minute sit-to-stand test is an alternative to 6MWT to measure functional exercise performance in COPD patients.

Chronic obstructive pulmonary disease (COPD) is frequently associated with a reduced functional exercise performance. Even if this parameter is routinely evaluated using 6-minute walking test (6MWT), new field tests are regularly investigated as alternative tests. The aim of this study was to compare functional exercise performance evaluation by sit-to-stand test (STST) and 6MWT and to evaluate reliability and repeatability of the STST in COPD patients. Forty-two COPD patients performed randomly two tests: 6MWT and STST. Each test was repeated two times. Distance (6MWD) and number of repetitions were measured. Cardiorespiratory parameters, dyspnea and lower limb fatigue (Borg) were recorded before and after the tests. Sit-to-stand repetitions (19 ± 6) and 6MWD (441 ± 104 m) were correlated (r = .716; P < .001). Good repeatability was found for STST and 6MWT. Good reliability was observed for STST (ICC = 0.902). Variations of heart rate and pulsed oxygen saturation were significantly different between these two tests (23% ± 17% vs 13% ± 11%; P = .022 and -7.6% ± 4.6% vs -0.7% ± 2.7%; P < .001 for 6MWT and STST, respectively). Variations of dyspnea and lower limb fatigue were similar between both tests (P = .827 and P = .467). The one minute sit-to-stand test is a valuable alternative to 6MWT to estimate functional exercise performance in COPD patients. The cardiorespiratory demand is different between both tests although the variation of dypsnea is similar. No learning effect was observed for STST.
