One of the functional tests most frequently used to analyse the characteristics of the functional gait is the Extended Timed Up and Go (Extended TUG). There is previous scientific literature that reliably identifies an exact calculation of this gait speed, which has recently become a validated test in our environment as a diagnostic tool for frailty. A slow gait velocity in healthy seniors acts as a predictor of adverse events, the early detection of which would favour priority interventions that could improve their physical condition and quality of life. The assessment of gait speed has been shown to be a reliable marker, both for assessing survival and for predicting adverse events in the elderly (falls, hospitalization, need for caregivers, etc.). Īmong the depletions associated with aging and frailty is a decrease in the speed of walking. Early detection of the particular situations that lead to the dependence of elderly people will enable the establishment of corrective measures to prolong an individual’s autonomy. Ĭurrently, the early identification of frailty is centred on the loss of functional capacities, comorbidities, the appearance of disability and dependencies, etc. These studies have allowed us to explain the frailty phenotype in a more adequate and empirical way, as a situation of biological instability related to the aging of human beings. In the last two decades, the concept of frailty has undergone a considerable change, associated with the development of epidemiological studies on population aging. The frailty associated with aging has been studied for decades. The world’s population is experiencing a gradual and incessant increase in the number of elderly people. The reliability of the Extended TUG test progressively decreases with increasing age, being excellent for the younger age groups and good for the oldest age group. Intergroup reliability, compared with intragroup reliability, was slightly lower, ranging between 0.779 for G3 and 0.972 for G1 (G2 = 0.853). Specifically, intragroup reliability ranged from 0.784 for G3 to 0.977 for G1 (G2 = 0.858). The reliability of the Extended TUG test is excellent for the first and second decades but drops down to good for the third decade. Both the intragroup and intergroup reliability of the measurements in the Extended TUG were analysed. Each participant performed the Extended TUG three consecutive times, with a rest break between tests of 120 s. MethodsĪn analytical cross-sectional study of 114 recruited participants (63 women) of average age 70.17 (± 7.3) years was undertaken. To analyse the reliability, variance and execution time of the Extended Timed Up and Go (Extended TUG) test in three age groups of elderly participants (G1: 55–64 years G2: 65–74 years G3: 75–85 years).
