Test Retest Reliability and Validity of 1-Minute Sit-to-Stand Test in Patients With Chronic Heart Failure

Aim: The psychometric properties of the 1-minute sit-to-stand (1STS) test have not been investigated in patients with chronic heart failure (CHF). The aim of this study was to evaluate test–retest reliability, construct validity, and minimal detectable change of the 1STS test and to investigate the physiological response to the 1STS test in patients with CHF. Method: Forty-three (43) patients with CHF were included. Demographic and clinical features were recorded. To investigate test–retest reliability, participants performed two 1STS tests on the same day. The correlations between the 1STS test and the 6-minute walk test (6MWT), functional class, pulmonary function, quadriceps muscle strength, and physical activity were investigated for validity. The physiological responses and symptom perception were assessed before and after both the 1STS test and 6MWT. Results: Excellent test–retest reliability was found for the 1STS test, with an intraclass correlation of 0.932 (95% confidence interval 0.874–0.963). The minimal detectable change of the 1STST test was 3.7 repetitions. The 1STS test was correlated with 6MWT distance, age, functional class, pulmonary function, quadriceps muscle strength, and physical activity (p0.05), except for leg fatigue (p=0.02). Conclusions: The 1STS test is reliable and valid in evaluating functional exercise capacity in patients with CHF. The 1STS test reveals similar cardiac demand to the 6MWT. The 1STS test may be considered an option when traditional tests are impractical in terms of space and time

Turkish translation, cross-cultural adaptation, and assessment of psychometric properties of the Functional Status Score for the Intensive Care Unit

WOS: 000470599300001PubMed ID: 31020855Purpose: To translate and cross-culturally adapt the Functional Status Score for the Intensive Care Unit instrument to Turkish and investigate its psychometric properties. Methods: An expert committee supervised forward and backward translation. Thirteen participants reviewed the pre-final version of Turkish Functional Status Score for the Intensive Care Unit instrument providing minor revisions to improve its readability. Two physiotherapists assessed patients (N = 50) from a coronary intensive care unit using the Turkish Functional Status Score for the Intensive Care Unit instrument. Results: Internal consistency was excellent (Cronbach's alpha = 0.949). Inter-rater reliability and intra-rater reliability were excellent for each of five functional tasks and total scores (intra-class correlation coefficient = 0.955-0.996). The Turkish Functional Status Score for the Intensive Care Unit score had moderate to high correlations with other functional measures as follows: Perme Intensive Care Unit Mobility Score (Spearman's r = 0.92), Katz Activities of Daily Living (r = 0.80), handgrip strength (r = 0.76-0.77), and knee extension strength (r = 0.70-0.71). Conclusion: The Functional Status Score for the Intensive Care Unit instrument was translated and culturally adapted to Turkish and demonstrated strong psychometric properties, including internal consistency, intra-rater and inter-rater reliability, construct validity, and floor and ceiling effects

Determinants of respiratory muscle strength in adult bronchiectasis

AbstractBackground:&nbsp;Respiratory muscle strength is widely used as an outcome measure in pulmonary rehabilitation programs. It is known that bronchiectasis affects respiratory muscle strength which has a crucial role in the growth of symptoms and functional limitation. Therefore, it is important to identify the determinants of respiratory muscle strength in patients with non-cystic fibrosis (non-CF) bronchiectasis.Aim:&nbsp;To identify the determinants of respiratory muscle strength in patients with non-CF bronchiectasis.Methods:&nbsp;Forty-one patients with non-CF bronchiectasis were recruited in this cross-sectional study. Demographic and spirometric values were recorded. Maximal inspiratory pressure [MIP] and maximal expiratory pressure [MIP] were evaluated using an electronic mouth pressure device. Fat-free mass, exercise capacity, quadriceps strength, and physical activity were assessed.Results:&nbsp;The mean age of patients was 58.8 y. MIP and MEP were correlated with fat-free mass (MIP: r=0.507, p=0.001; MEP: r=0.669, p&lt;0.001), ISWT distance (MIP: r=0.374, p=0.01; MEP: r=0.396, p=0.01), quadriceps strength (MIP: r =0.511, p=0.001; MEP: r =0.508, p=0.001) and total energy expenditure (MIP: r=0.392, p=0.01; MEP: r=0.476, p=0.002). The multiple regression analysis revealed that fat-free mass and quadriceps strength were independent predictors of MIP, accounted for 32% of the variance. Fat-free mass was independent predictors of MEP, accounted for 45.9% of the variance.Conclusions:&nbsp;Fat-free mass and quadriceps strength were found as determinants of respiratory muscle strength in patients. Respiratory muscle strength may be increased by improving fat-free mass and quadriceps strength in adult non-CF bronchiectasis.</p

Factors Influencing Activities of Daily Living in Subjects With COPD

WOS: 000457372700011PubMed ID: 30401755BACKGROUND: Activities of daily living (ADL) are important for an independent life. As COPD progresses, the ability to complete ADL is usually reduced. Knowing the possible factors that influence the ability to perform ADL may allow better targeting of appropriate rehabilitation programs to increase the independence levels and/or to prevent further decreases in patients with COPD. Therefore, the aim of this study was to investigate ADL performance as measured by the London Chest Activity of Daily Living scale, which is a commonly used measure in patients with COPD. METHODS: This cross-sectional study included 44 clinically stable subjects who were not taking antibiotics and had not made any changes in their medications for at least three weeks with a COPD diagnosis based on Global Initiative for Chronic Obstructive Lung Disease. Demographic characteristics, pulmonary function, ADL measured by the London Chest Activity of Daily Living scale, functional exercise capacity via the 6-min walk distance, disease-related symptoms measured by the COPD Assessment Test, and peripheral and respiratory muscle strength were evaluated. A multiple linear regression (stepwise) analysis was used to determine the variables that have the greatest influence on ADL (ie, the London Chest Activity of Daily Living scale score). RESULTS: The London Chest Activity of Daily Living scale score had moderate correlations with the COPD Assessment Test score (r = 031, P = .041), maximum expiratory pressure value (r = -037, P = .01), 6-min walk distance (r = -0.48, P = .001), knee extensor muscle strength (r = -0.47, P = .001), handgrip strength (r = -0.44, P = .003). The 6-min walk distance, COPD Assessment Test score and maximal expiratory pressure values were significant and independent determinants of the London Chest Activity of Daily Living scale, with 40.1% of the variance in subjects with COPD. CONCLUSIONS: Functional exercise capacity, disease-related symptoms, and expiratory muscle strength have the greatest influence on ADL in the subjects with COPD. The level of independence to perform ADL can be increased by improving functional exercise capacity, reducing symptoms, and increasing expiratory muscle strength in subjects with COPD
