In clinical rehabilitation, the Timed Up-and-Go Test (TUG-T) is known as a simple technique for evaluating basic activities, especially the risk of falling. Usually, the time of TUG-T is counted, and the correlation between falling phenomenon and time of TUG is relatively high. We have been examining a quantitative evaluation method of the activity using the signal of an accelerometer attached to the lumbar position. However, it is difficult to specify the activities phase clearly from the signal obtained by the accelerometer. Thus, in this study, we propose a combination of accelerometer and rate gyro-sensor to specify the activity phase of TUG-T. For the comparison, trained therapists measured the time for each activity phase using VTR images. As a result, proposed classifications of activity phase well correlated to the observations made by the therapists. In the use of both accelerometer and the gyro-sensor signals, it was possible for the activity phase to make detections similar to those of therapists' observations.
