, Vaugoyeau, Nougier, & Assaiante, 2010 ). Among several mobility tests, the timed up and go test (TUGT) is a useful tool for gait, balance, and risk of falls assessment ( Alexandre, Meira, Rico, & Mizuta, 2012 ). Gillain et al. ( 2009 ) found differences in TUGT (total performance) when using triaxial

With the high prevalence of debilitating injuries associated with accidental falls in senior citizens, the need for clinicians to have valid and reliable methods of risk assessment that can be administered efficiently at low financial cost is important. The Timed Up and Go (TUG) test has been

This study assessed functional balance among older adults at all grades of chronic obstructive pulmonary disease (COPD) and explored balance impairment predictors. A cross-sectional study with outpatients with COPD (N = 160; M = 72.2 years, SD = 7.9; mean forced expiratory volume in 1 s = 63.8% predicted, SD = 23.7) was conducted. The Timed Up and Go (TUG) test was used to assess functional balance. Functional balance impairment was defined as a TUG score exceeding the upper limit of the confidence intervals of normative values for healthy older adults. Participants performed the TUG test in 11.0 s (SD = 4.8 s). Functional balance impairment was present in 44.4% of the participants and was significantly more frequent in severe to very severe COPD (62.5%). Body mass index (odds ratio [OR] = 1.12), number of medications (OR = 1.20), restriction in recreational activities (OR = 1.66), and depression score (OR = 1.14) were multivariate predictors of functional balance impairment. Functional balance impairment is present in early COPD, although more evident at advanced grades. These findings highlight the importance of balance assessment in older patients at all COPD grades.

To investigate reasons for the age-related reduction in physical function, we determined the relationships between muscle size, strength, and power with 6-min walk distance (6MWD) and timed up-and-go performance in 49 young (23 ± 3.1 years) and 66 healthy, mobile older adults (72 ± 5 years). While muscle mass, determined by DXA and MRI, did not correlate with performance in the older adults, power per body mass, determined from a countermovement jump, did correlate. The 40% lower jumping power observed in older adults (p < .05) was due to a lower take-off velocity, which explained 34% and 42% of the variance in 6MWD in older women and men, respectively (p < .01). The lower velocity was partly attributable to the higher body mass to maximal force ratio, but most was due to a lower intrinsic muscle speed. While changes in muscle function explain part of the age-related reduction in functional performance, ~60% of the deficit remains to be explained.

community-dwelling older adults. The timed up and go (TUG) and 5 times sit-to-stand (5×STS) scores are 2 of the 3 most evidence-supported performance-based measures for assessing fall risk in community-based older adults. 3 TUG performance is predictive of fall history and future falls in older adults. 18
