To investigate the discriminative ability and diagnostic accuracy of the Timed Up and Go Test (TUG) as a clinical screening instrument for identifying older people at risk of falling.Abstract:
OBJECTIVES: To investigate the discriminative ability and diagnostic accuracy of the Timed Up and Go Test (TUG) as a clinical screening instrument for identifying older people at risk of falling. DESIGN: Systematic literature review and meta-analysis. SETTING AND PARTICIPANTS: People aged 60 and older living independently or in institutional settings. MEASUREMENTS: Studies were identified with searches of the PubMed, EMBASE, CINAHL, and Cochrane CENTRAL data bases. Retrospective and prospective cohort studies comparing times to complete any version of the TUG of fallers and non-fallers were included. RESULTS: Fifty-three studies with 12,832 participants met the inclusion criteria. The pooled mean difference between fallers and non-fallers depended on the functional status of the cohort investigated: 0.63 seconds (95% confidence (CI) = 0.14-1.12 seconds) for high-functioning to 3.59 seconds (95% CI = 2.18-4.99 seconds) for those in institutional settings. The majority of studies did not retain TUG scores in multivariate analysis. Derived cut-points varied greatly between studies, and with the exception of a few small studies, diagnostic accuracy was poor to moderate. CONCLUSION: The findings suggest that the TUG is not useful for discriminating fallers from non-fallers in healthy, high-functioning older people but is of more value in less-healthy, lower-functioning older people. Overall, the predictive ability and diagnostic accuracy of the TUG are at best moderate. No cut-point can be recommended. Quick, multifactorial fall risk screens should be considered to provide additional information for identifying older people at risk of falls. Language: enread more

Is the Timed Up and Go test a useful predictor of risk of falls in community dwelling older adults: a systematic review and meta- analysis
TL;DR: The Timed Up and Go test has limited ability to predict falls in community dwelling elderly and should not be used in isolation to identify individuals at high risk of falls in this setting.

TL;DR: Risk stratification of geriatric adults following ED care is limited by the lack of pragmatic, accurate, and reliable instruments and Clinicians, educators, and policy-makers should not use these instruments as valid predictors of post-ED adverse outcomes.

TL;DR: The essential physiology underlying functional capacity on systemic, organ, and cellular levels is reviewed, as well as critical clinical skills to measure multiple realms of function (eg, aerobic, strength, balance, and even cognition) that are particularly relevant for older patients.

TL;DR: In this paper, the authors aimed to prospectively examine individual muscle mass and muscle strength in older adults and found that muscle strength and muscle mass may independently or synergistically affect aging-related health outcomes.

Falls and fractures: a systematic approach to screening and prevention
TL;DR: The major risk factors identified are impaired balance and gait, polypharmacy, and history of previous falls, which include advancing age, female gender, visual impairments, cognitive decline especially attention and executive dysfunction, and environmental factors.

The Timed “Up & Go”: A Test of Basic Functional Mobility for Frail Elderly Persons
TL;DR: This study evaluated a modified, timed version of the “Get‐Up and Go” Test (Mathias et al, 1986) in 60 patients referred to a Geriatric Day Hospital and suggested that the timed “Up & Go’ test is a reliable and valid test for quantifying functional mobility that may also be useful in following clinical change over time.

The development of QUADAS: a tool for the quality assessment of studies of diagnostic accuracy included in systematic reviews
TL;DR: In this article, an evidence-based quality assessment tool called QUADAS was proposed to assess the quality of primary studies of diagnostic accuracy, based on the results of three previously conducted reviews of the diagnostic literature.

Predicting the probability for falls in community-dwelling older adults using the Timed Up & Go Test.
TL;DR: The TUG is a sensitive and specific measure for identifying community-dwelling adults who are at risk for falls and the ability to predict falls is not enhanced by adding a secondary task when performing the TUG.

TL;DR: Considerable evidence now documents that the most effective (and cost-effective) fall reduction programmes have involved systematic fall risk assessment and targeted interventions, exercise programmes and environmental-inspection and hazard-reduction programmes.
