Additionally, it requires minimal equipment and allows subjects with functional disabilities to perform the evaluation. Other advantages of TUG are the simplicity and duration of its application. This test presents a high inter-rater and intra-rater reliability, with values greater than 95% in the prediction of RoF in elderlies, people with stroke and Parkinson’s disease (PD). The controlled variable is the total test duration in seconds, which is then correlated with the RoF. It consists of a circuit in which the subject must get up from a chair, walk three meters, turn around and walk back to the chair to sit on it again ( Figure 1). as a timed modification of the ”Get up and Go” test. It was developed in 1991 by Podsiadlo et al. ![]() The TUG test is a simple test that can be applied in several environments. One of the most widely used tests is the Timed Up and Go (TUG), which measures dynamic balance and functional mobility. In clinical practice, different tests and observational scales are used to measure static and dynamic balance, as well as gait in healthy subjects or with motor impairments. For this, proposals to identify people with RoF, and measure balance and gait. The most common intrinsic factors are muscle weakness, balance deficits, and gait instability. The main causes of falls are multi-factorial, including extrinsic factors related to the environment, intrinsic factors related to the person, and behavioral factors related to the activity. Therefore, it is important to detect risk factors of falls and balance early, to implement effective and specific preventive clinical strategies. Thus, the clinical guidelines of “The American and British Geriatric Societies” recommend asking elderlies over 65 years if they have suffered two or more falls, if they have been injured during a fall or if they perceive any difficulty walking or maintaining balance. For this reason, the risk of falls (RoF) is a public health issue, being considered one of the main causes of serious injuries in elderlies and the third cause of death due to unintentional injury, causing a sedentary life, loss of functional capacity and a decrease in the quality of life. In total, 25% of the elderly population suffer at least one fall per year, increasing to two falls when the age is greater than 70 years. The iTUG test offers an economical and accessible alternative to increase the predictive value of TUG, identifying different variables, and can be used in clinical, community, and home settings.įalls are accidental events in which people lose control of their center of gravity, where the effort to regain balance is insufficient. In total, 97.5% of the studies applied automatic segmentation using rule-based algorithms. The most used technology was inertial sensors (75% of the studies), with healthy elderlies (35%) and elderlies with Parkinson’s disease (32.5%) being the most analyzed participants. The review included 40 studies that met the eligibility criteria. A search was conducted in five major databases, following PRISMA guidelines. This systematic review aims to explore the evidence of the technological proposal for the segmentation and analysis of iTUG in elderlies with or without pathologies. However, to increase the test’s predictive value, the instrumented Timed Up and Go (iTUG) test has been developed, incorporating different technological approaches. Patients whose performance exceeds the upper limit of reported confidence intervals can be considered to have worse than average performance.The Timed Up and Go (TUG) test is a widely used tool for assessing the risk of falls in older adults. The reference values presented, though obtained from studies with clear differences, provide a standard to which patient performance can be compared. Although the data contributing to this mean were homogeneous, data for individuals who could be categorized by age were more homogeneous. The mean (95% confidence interval) TUG time for individuals at least 60 years of age was 9.4 (8.9-9.9) seconds. Twenty-one studies were included in the meta-analysis. Study specifics and data were consolidated and examined for homogeneity. ![]() ![]() Studies reporting TUG times for apparently healthy elders were identified through the on-line search of bibliographic databases. This meta-analysis provided such values by consolidating data from multiple studies. The Timed Up and Go (TUG) test is widely employed in the examination of elders, but definitive normative reference values are lacking. ![]()
