Inertial sensor and Timed Up and Go test in elderly women with bone demineralization: a reliability and agreement study
The study aims to assess: 1) reliability test-retest and error measures of quantitative variables of Timed Up and Go (TUG) testing collected with the inertial sensor wireless Wiva ® Science (TUGis), and 2) the agreement of TUGis and the timed method (TUGs) and between the two methods applied to elderly women with osteoporosis and osteopenia. Eighteen elderly women with bone demineralization were enrolled in this study.The time (s) for two executions of the TUG (T1 and T2) was measured with a manual stopwatch by an evaluator and with the inertial sensor attached to the body at the level of the L5 vertebra with remote collection.T1 and T2 were performed with an interval of 1 min. TUG's subtasks were also captured by the inertial sensor. The reliability test-retest and error variables were assessed by the intraclass correlation coefficient (ICC), standard error of measurement (SEm) and minimal detectable change (MDC). The agreement between the averages from the total time of the TUGs and TUGis and between T1 and T2 measured with the sensor and stopwatch were evaluated by the Bland-Altman method. The consistency inside of the subtasks TUGis ranged from substantial to almost complete. The SEm and MDC for TUGis were 1.27s and 2.48s, respectively. The agreement between sensor and stopwatch measurements showed low systematic error. The inertial sensor was reliable in verifying the performance of the TUG and can be a complement for assessing the risk of falls and functional mobility of elderly women with bone demineralization. However, it does not represent an improvement in the exclusive investigation of the total test time.
