    Sit-to-stand test in children with bronchiectasis: Does it measure functional exercise capacity?
    (2020-09-01T00:00:00Z) Zeren, Melih; Gürses, Hülya Nilgün; Denizoğlu Külli, Hilal; Uçgun, Hikmet; Çakır, Erkan; GÜRSES, HÜLYA NILGÜN; DENİZOĞLU KÜLLİ, HİLAL; UÇGUN, HİKMET; ÇAKIR, ERKAN
    Background Similar to six-minute walk test (6MWT), sit-to-stand test (STST) is a self-paced test which elicits sub-maximal effort; therefore, it is suggested as an alternative measurement for functional exercise capacity in various pulmonary conditions including COPD and cystic fibrosis. We aimed to investigate the association between 30-second STST (30s-STST) and 6MWT in both children with bronchiectasis (BE) and their healthy counterparts, as well as exploring cardiorespiratory burden and discriminative properties of both tests. Methods Sixty children (6 to 18-year-old) diagnosed with non-cystic fibrosis BE and 20 age-matched healthy controls were included. Both groups performed 30s-STST and 6MWT. Test results, and heart rate, SpO2 and dyspnea responses to tests were recorded. Results Univariate analysis revealed that 30s-STST was able to explain 52% of variance in 6MWT (r = 0.718, p<0.001) in BE group, whereas 20% of variance in healthy controls (r = 0.453, p = 0.045). 6MWT elicited higher changes in heart rate and dyspnea level compared to 30s-STST, indicating it was more physically demanding. Both 30s-STST (21.65±5.28 vs 26.55±3.56 repetitions) and 6MWT (538±85 vs 596±54 m) were significantly lower in BE group compared to healthy controls (p<0.01). Receiver operating characteristic (ROC) curve analysis revealed an area under the ROC curve (UAC) of 0.765 for 30s-STST and 0.693 for 6MWT in identifying the individuals with or without BE (p<0.05). Comparison between AUCs of 30s-STST and 6MWT yielded no significant difference (p = 0.466), indicating both tests had similar discriminative properties. Conclusions 30s-STST is found to be a valid alternative measurement for functional exercise capacity in children with BE.

    The relationship of sit-to-stand tests with 6-minute walk test in healthy young adults
    (2018-01-01) Gurses, HÜLYA NİLGÜN; Zeren, MELİH; Kulli, Hilal Denizoglu; Durgut, ELİF; GÜRSES, HÜLYA NILGÜN; ZEREN, MELIH; DENİZOĞLU KÜLLİ, HİLAL; DURGUT, ELİF
    The aim of this study was to evaluate the timed sit-to-stand (STS) test performances of healthy young adults and to investigate the relationship of timed STS tests with 6-minute walk test (6MWT). A cross-sectional study was performed. A total of 40 healthy volunteers (mean age: 21.7 +/- 1.2 years) were evaluated with 10, 30, and 60seconds STS tests and 6MWT. Fatigue and shortness of breath were rated using Borg category-ratio scale (CR10) before and after each test. Weekly energy expenditures of volunteers were calculated using International Physical Activity Questionnaire. 30 and 60seconds STS tests were moderately (r=0.611 and r=0.647, respectively) (P.05). Borg fatigue scores after 10, 30, and 60seconds STS tests were weakly correlated with fatigue score after 6MWT (r=0.321, r=0.378, and r=0.405, respectively) (P<.05). Weekly energy expenditure (MET-min/week) was moderately correlated with 10, 30, and 60seconds STS tests and 6MWT (r=0.533, r=0.598, r=0.598, and r=0.547, respectively) (P<.001). Considering the statistically significant relationship between timed STS tests and 6MWT, any of the timed STS tests may be used for a quick and alternative measurement of physical performance and functional capacity in healthy young adults.
