RT journal article T1 Inter-rater and intra-rater reliability of the extended TUG test in elderly participants A1 Bedoya-Belmonte, Juan José A1 Rodríguez-González, María del Mar A1 González-Sánchez, Manuel A1 Barreda Pitarch, Jose Miguel A1 Galán Mercant, Alejandro A2 Enfermería y Fisioterapia AB Background: To analyse the reliability, variance and execution time of the Extended Timed Up and Go (ExtendedTUG) test in three age groups of elderly participants (G1: 55–64 years; G2: 65–74 years; G3: 75–85 years).Methods: An analytical cross-sectional study of 114 recruited participants (63 women) of average age 70.17 (± 7.3) yearswas undertaken. Each participant performed the Extended TUG three consecutive times, with a rest break between tests of120 s. Both the intragroup and intergroup reliability of the measurements in the Extended TUG were analysed.Results: The reliability of the Extended TUG test is excellent for the first and second decades but drops down to good forthe third decade. Specifically, intragroup reliability ranged from 0.784 for G3 to 0.977 for G1 (G2 = 0.858). Intergroup reliability,compared with intragroup reliability, was slightly lower, ranging between 0.779 for G3 and 0.972 for G1 (G2 = 0.853).Conclusion: The reliability of the Extended TUG test progressively decreases with increasing age, being excellent for theyounger age groups and good for the oldest age group.
