![]() 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. The Timed Up and Go (TUG) test is a widely used tool for assessing the risk of falls in older adults.
