Is there a Difference between the Timed Up and Go Test and Physical Function due to the Difference in Perception of Slip?

The purpose of this study was to examine whether there are differences in the timed up and go (TUG) test results and physical functions due to the differences in slip recognition when performing TUG on wood flooring. The study consisted of 30 community-dwelling elderly subjects, aging over 65 years old. The differences in the perception of floor slippage before and after TUG were as follows: (1) slippery-slipped group (S-S group), (2) slippery-not slipped group (S-N group), and (3) not slippery-not slipped group (N-N group). The modified falls efficacy scale, grip strength, knee extension strength, one-leg standing time, functional reach test, Trail Making Test (TMT), two-step test were used in this study. The results showed no statistically significant difference in TUG test. However, statistically significant difference was observed in TMT between the S-S and N-N groups (p = 0.019, r = 0.51, respectively) and between the S-S and S-N groups (p = 0.003, r = 0.65, respectively). It was found that there was no statistically significant difference in TUG results due to the recognition differences of slippage. However, it was suggested that the subject who reported a history of slippage had a high attention function and could pay attention to the floor environment.
