11 A TUG-score of >20 seconds was identified as a cut-off point for sarcopenia by the European Working Group on Sarcopenia in Older People. 7 Poor TUG performance (high TUG score in seconds) may predict an increased length of hospital stay, 8 mortality, 9 low quality of life, low social participation, 10 and the onset of difficulty with activities of daily living. The Timed Up and Go (TUG) test is a simple, quick, and widely used clinical performance-based measure of mobility and balance. 4, 5 The identification of mobility impairments requires normative reference values to which an individual’s mobility score measurements can be compared. Performance-based outcome measures or standardized observer-rated observations are important tools for evaluating performance in clinical intervention practice and research studies as well as for identifying impairment. 3 The assessment of physical function can be useful for several purposes, such as to identify a decline in physical function, monitor the effect of exercise interventions, and provide specific information regarding physical domains, eg strength, balance and mobility.
1 Physical function declines with age, and some of the first signs of functional decline are reduced mobility, loss of muscular strength, and difficulties in performing daily activities, 2 of which mobility is the most important factor for maintaining independence. Physical function is a strong biomarker of health in older adults.
