Background: Subjects with Rheumatoid Arthritis (RA) have a high risk of falling. The Timed Up and Go test (TUG) is used to predict the risk of falls but it has not been validated in subjects with RA. Purpose: The primary objective was to establish the predictive validity and the concurrent validity of TUG at the preferred walking speed or fastest speed possible as a predictor of falls in subjects with RA. The secondary objective was to establish if the TUG has a higher predictive value evaluated at the preferred walking speed or fastest speed possible. Subjects and method: The subjects were admitted by consecutive non-probabilistic sampling. To establish the concurrent validity, the TUG was correlated with the Berg Balance Scale (BBS) and the 10-meter Walk Test (TM10m). Predictive validity was calculated using the operating characteristics curve for the receiver and the area under the curve. Results: 115 participants were evaluated for concurrent validity and 98 for predictive validity.
