Abstract
Throughout the years the relevance of Time Up and Go Test (TUG) to qualify or even quantify the patients’ global motor state became clear. Nonetheless, it is evidenced that the conventional result, i.e, the total duration of TUG, is not able to describe a specific problem. The aim of this work is to develop a multi-sensor wearable platform based on redundant inertial sensors (RIMU) able to automatically calculate both the user cadence and the duration of each TUG phase. Eight volunteers without gait disabilities wore the RIMU system during 5 meters TUG, and the data were compared to reference systems. The results presented an average RMSE (root-mean-square error) of 5.20 steps/min for cadence and 0.48 seconds for total duration TUG. In conclusion, the proposed instrumented TUG is an easy-to-perform test and may be an alternative to assess the initial motor state of patients.
