“…This is the first study to thoroughly assess the measurement properties of the 1-min STS test in COPD patients. Our findings for cross-sectional validity of the 1-min STS test were in accordance with previous studies that also found moderate to strong correlations (r=0.47-0.75) with the 6MWT [5,15] and with quadriceps strength (r=0.65) [5]. Many measures met our assumptions about strength of correlation, indicating good cross-sectional construct validity; however, the poor change score correlations with exercise capacity tests (<0.4) suggest that they may measure different aspects of exercise capacity that are not correlated over time.…”

“…While the 1-min STS test is increasingly used in studies of COPD patients [8,[10][11][12][13][14][15][16], its learning effect, reliability, responsiveness to change and minimal important difference (MID) have not yet been established in this patient population. Furthermore, little is known about the physiological response to the 1-min STS test in terms of the cardiorespiratory stress elicited.…”

Our aim was to comprehensively validate the 1-min sit-to-stand (STS) test in chronic obstructive pulmonary disease (COPD) patients and explore the physiological response to the test.We used data from two longitudinal studies of COPD patients who completed inpatient pulmonary rehabilitation programmes. We collected 1-min STS test, 6-min walk test (6MWT), health-related quality of life, dyspnoea and exercise cardiorespiratory data at admission and discharge. We assessed the learning effect, test-retest reliability, construct validity, responsiveness and minimal important difference of the 1-min STS test.In both studies (n=52 and n=203) the 1-min STS test was strongly correlated with the 6MWT at admission (r=0.59 and 0.64, respectively) and discharge (r=0.67 and 0.68, respectively). Intraclass correlation coefficients (95% CI) between 1-min STS tests were 0.93 (0.83-0.97) for learning effect and 0.99 (0.97-1.00) for reliability. Standardised response means (95% CI) were 0.87 (0.58-1.16) and 0.91 (0.78-1.07). The estimated minimal important difference was three repetitions. End-exercise oxygen consumption, carbon dioxide output, ventilation, breathing frequency and heart rate were similar in the 1-min STS test and 6MWT.The 1-min STS test is a reliable, valid and responsive test for measuring functional exercise capacity in COPD patients and elicited a physiological response comparable to that of the 6MWT.

“…Several studies [10,19,21,22,28,37] have compared the STST with the 6MWT in order to assess its relevance as a tool for evaluation of functional status in COPD patients and healthy subjects. The results obtained by Ozalevli et al in COPD showed a strong correlation between performance in the 1 min-STST and distance walked in the 6-min (r ¼ 0.75, p < 0.001).…”

Background: Sit-to-stand tests (STST) have recently been developed as easy-to-use field tests to evaluate exercise tolerance in COPD patients. As several modalities of the test exist, this review presents a synthesis of the advantages and limitations of these tools with the objective of helping health professionals to identify the STST modality most appropriate for their patients. Method: Seventeen original articles dealing with STST in COPD patients have been identified and analysed including eleven on 1min-STST and four other versions of the test (ranging from 5 to 10 repetitions and from 30 s to 3 min). In these studies the results obtained in sit-to-stand tests and the recorded physiological variables have been correlated with the results reported in other functional tests. Results: A good set of correlations was achieved between STST performances and the results reported in other functional tests, as well as quality of life scores and prognostic index. According to the different STST versions the processes involved in performance are different and consistent with more or less pronounced associations with various physical qualities. These tests are easy to use in a home environment, with excellent metrological properties and responsiveness to pulmonary rehabilitation, even though repetition of the same movement remains a fragmented and restrictive approach to overall physical evaluation. Conclusions: The STST appears to be a relevant and valid tool to assess functional status in COPD patients. While all versions of STST have been tested in COPD patients, they should not be considered as equivalent or interchangeable.

“…11 The 1-min sit-to-stand (STS) test is a rapid and simple test that is increasingly used in respiratory diseases such as COPD. [12][13][14] The STS movement is frequently performed in daily living and is thought to be a measure of lower-limb strength. The STS test has been recently demonstrated to be reliable and sensitive to intervention in a small sample of adults with CF.…”

BACKGROUND: Exercise testing is part of the regular assessment of patients with cystic fibrosis (CF). We aimed to evaluate (1) the convergent validity of the 1-min sit-to-stand (STS) test in CF by investigating its relationships with peak oxygen uptake (peak V O 2 ), quadriceps strength, and quality of life and (2) to compare these associations with those of the 6-min walk test (6MWT). METHODS: Twenty-five adults with CF (FEV 1 ‫؍‬ 59 ؎ 24%) performed the STS test, the 6MWT, quadriceps strength assessment, and cardiopulmonary exercise test (CPET). Physical activity level, quality of life, and self-esteem were assessed by questionnaires. RESULTS: STS repetitions, 6-min walk distance, quadriceps strength, and peak V O 2 were, respectively, 71 ؎ 12, 90 ؎ 10, 93 ؎ 29, and 62 ؎ 16% of predicted. The STS test had moderate associations with peak V O 2 (r ‫؍‬ 0.56, P ‫؍‬ .004), quadriceps strength (r ‫؍‬ 0.52, P ‫؍‬ .008), and some questionnaire items (eg, perceived physical strength, r ‫؍‬ 0.67, P < .001) only when repetitions were expressed as a product of body weight. Overall, these associations were weaker than those obtained from 6-min walk distance ؋ weight. Oxygen desaturation during the STS test was strongly associated with oxygen desaturation during CPET (r ‫؍‬ 0.80, P < .001). Peak heart rate was lower during the STS test as compared with CPET (P < .001) and the 6MWT (P ‫؍‬ .009). CONCLUSIONS: The STS test cannot be used as a replacement for CPET to accurately assess peak exercise capacity in CF. The STS test may have utility in detecting patients with CF who may exhibit a high level of oxygen desaturation during heavy exercise. Further studies should identify the factors contributing to STS performance to confirm the potential interest of STS repetitions ؋ body weight outcome as a useful submaximal exercise parameter in CF.
