ABSTRACT
Background:
The Timed up and Go Test (TUG) is often used as a mobility measure in older people. However, it is unclear whether the TUG is useful for identifying fall risk in people with diabetes mellitus (DM) and which physical and cognitive/psychological factors influence the performance of this test.Objectives:
To investigate whether slow TUG times (standard test and when performed with a secondary cognitive task (c-TUG)) are a risk factor for falls in older people with DM and to determine the relative contributions of a range of sensorimotor, balance and cognitive/psychological factors to TUG performance in this population.Methods:
Community-dwelling people (n=103, mean age 61.57, SD=6.3) underwent the TUG and c-TUG tests as well as quantitative tests of vision, peripheral sensation, strength, reaction time, balance, cognition, and fear of falling. Participants were then followed up for falls for six months.Results:
Negative binomial regression analyses revealed that each 1s increase in TUG and c-TUG times increased the risk of falling by 29% and 13%, respectively. Multiple regression analyses identified vibration sense (p<0.001), knee extension strength (p=0.001, r²=0.430), edge contrast sensitivity (p=0.002), neuropathy examination score (p=0.001, r²=0.498) and controlled leaning balance (p=0.033) as significant and independent explanatory predictors of TUG performance. The regression model for c-TUG was similar, vibration sense (p=0.042), knee extension strength (p=0.009, r²=0.256), neuropathy examination score (p=0.156, r²=0.272) and sway path-floor (p=0.042) except that the MOCA cognitive assessment (p=0.015) was included instead of edge contrast sensitivity. The combined explanatory variable models explained 43% and 26% of the variance in TUG and c-TUG times, respectively.Conclusions:
Slow TUG and c-TUG times significantly increased the risk of falls in community-dwelling older people with DM. Poor TUG and c-TUG performances were related independently to decreased vibration sense, lower limb weakness, and poor balance, with the c-TUG additionally influenced by cognitive function.
