![]() ![]() A BBS score of ≤45 indicated balance impairment in this study ( 14). Balance tests were measured using the Berg Balance Scale (BBS) and the TUG test. ![]() This cross-sectional study was conducted at a single visit in COPD patient at Maharaj Nakorn Chiang Mai Hospital, Chiang Mai, Thailand from November 2015 to October 2017. Therefore, the aim of this study was to examine the diagnostic ability of the TUG test for identifying balance impairment in COPD. However, there are few data regarding the cut-off point of the TUG test that could predict balance impairment in COPD patients. ( 11) suggest that a cut-off 11 and 12 seconds could predict fall in patients with COPD, respectively. ![]() Some studies indicated that the TUG could be used for predicting history of falling and exercise capacity in COPD ( 10- 13). The Timed Up and Go (TUG) test is recommended as a routine screening test for balance impairment and falls in older adults ( 9). A number of tests have been developed to quantitatively measure balance in the elderly population ( 8). Although a balance impairment assessment is now recommended by the guidelines for pulmonary rehabilitation program, specific tests have yet to be suggested ( 7). Balance impairment should be evaluated in older adults including COPD as a screen for identifying individuals who may benefit from a multifactorial fall risk assessment. Therefore, reducing the fall risk is very important and assessment of balance impairment in elderly especially in COPD should be addressed ( 6). Besides negative effects on mortality and morbidity, falls are linked to poorer overall functional status and quality of life ( 5). The greater fall risk in COPD patients needs more consideration of modifiable factors. also showed that the incidence of falling in patients with COPD was significant higher than non-COPD subjects (44.9 per 1,000 person-years vs. Previous studies showed the incidence of falling in COPD patients varies from 25.0–31.7% ( 2, 3). Accepted for publication Mar 04, 2020.įalling is a common problem in elderly people including in subjects with chronic obstructive pulmonary disease (COPD) ( 1). Keywords: Chronic obstructive pulmonary disease (COPD) balance movement falls validity The result supports a potential role for this simple test to be incorporated into routine COPD assessment to stratify patients’ balance. Multivariable analysis identified the TUG test time ≥12 seconds was the best predictor of balance impairment in COPD patients with adjusted risk ratio (RR) of 25.2 (95% CI: 1.6, 312.0, P=0.021) and, the AUROC was 0.98 (95% CI 0.96, 1.00).Ĭonclusions: Our study indicates the TUG test time ≥12 seconds has a high diagnostic ability for balance impairment prediction in COPD. A cut off point of TUG test time ≥12 seconds had sensitivity, specificity, LR+, LR−, Youden’s index, and AUROC of 95.8%, 90.4%, 10.01, 0.05, 86.2, and 0.93 for detecting balance impairment, respectively. Univariable analysis showed that the AUROC of TUG test to indicate those who had impaired balance was 0.93. Results: One hundred and eighteen smoking related COPD subjects 86 (72.9% male) with a mean age of 73.5☘.1 years were included in this study. Multivariable logistic regressions were performed to identify the optimum cut off point of TUG test time for prediction of balance impairment in COPD. The TUG was evaluated using sensitivity, specificity, positive likelihood ratio (LR+), negative likelihood ratio (LR−), Youden’s index, and the area under receiver operating characteristic curve (AUROC) from various points of TUG to identify the optimum cut-off point for detecting balance impairment. Balance impairment test was measured using the Berg Balance Scale (BBS), a score of ≤45 indicates balance impairment. Methods: The cross-sectional study was conducted in stable COPD patient at Maharaj Nakorn Chiang Mai Hospital, Chiang Mai, Thailand from November 2015 to October 2017. Thus the aim of this study was to evaluate the diagnostic ability relative to balance impairment of the TUG in subjects with COPD. Nowadays, we need more data of an optimum cut off point of TUG time for detecting balance impairment in patients with chronic obstructive pulmonary disease (COPD). The Timed Up and Go (TUG) test is a simple measure of balance status and functional mobility.
