Examination of Validity for Timed Up and Go Test which Added Upper-limbs Operation in Elderly Persons with Mild Disequilibrium

Purpose: We investigated the usefulness of the timed up and go (TUG) test incorporating an upper limb task as well as its relationships with muscle strength and static balance. Subjects: The subjects were 32 elderly persons with low-level care needs (level 1: 20, level 2: 12). Methods: We measured the time and number of steps taken in the TUG test, and a modified TUG (c-TUG) test in which subjects had to carry a 500cc cup filled with water, and analyzed the results using two-way ANOVA. We also analyzed the relationships of the results with the eyes-open single-leg standing time, as an index of static balance, and grip strength, as an index of muscle strength. Results: Regarding the TUG performance times, the level of care needs showed significant main and interaction effects for each of the tests. However, for the number of steps taken, only a main effect was found. The TUG time showed significant negative correlations with the indices of static balance and muscle strength, but not the c-TUG test. Conclusion: Our results suggest that the c-TUG test result is an index better reflecting comprehensive balance factors than the conventional TUG test, and we consider it will be very useful as a balance assessment method for elderly subjects with care needs.
