Conclusion The Timed Up and Go test has limited ability to predict  falls in community dwelling elderly and should not be used in isolation to identify individuals at high risk of falls in this setting
Background The Timed Up and Go test ( TUG ) is a commonly used screening tool to assist clinicians to identify patients at risk of falling .
The purpose of this systematic review and meta- analysis is to determine the overall predictive value of the TUG in community-dwelling older adults .
Functional Gait Assessment: Concurrent, Discriminative, and Predictive Validity in Community-Dwelling Older Adults
Background The Functional Gait Assessment ( FGA ) is a reliable and valid measure of gait-related activities . Objective The purpose of this study was to determine the concurrent , discriminative , and predictive validity of the FGA in community-dwelling older adults . Design This was a prospect i ve cohort study . Methods Thirty-five older adults aged 60 to 90 years completed the Activities-specific Balance Confidence Scale ( ABC ) , Berg Balance Scale ( BBS ) , Dynamic Gait Index ( DGI ) , Timed “ Up & Go ” Test ( TUG ) , and Functional Gait Assessment ( FGA ) during one session . Falls were tracked by having participants complete a monthly fall calendar for 6 months . Spearman correlation coefficients were used to determine concurrent validity among the ABC , BBS , TUG , DGI , and FGA . To determine the optimum scores to classify fall risk , sensitivity ( Sn ) , specificity ( Sp ) , and positive and negative likelihood ratios ( LR+ and LR− ) were calculated for the FGA in classifying fall risk based on the published criterion scores of the DGI and TUG and for the FGA , TUG , and DGI in identifying prospect i ve falls . Receiver operator curves with area under the curve were used to determine the effectiveness of the FGA in classifying fall risk and of the DGI , TUG , and FGA in identifying prospect i ve falls . Results The FGA correlated with the ABC ( r=.053 , P<.001 ) , BBS ( r=.84 , P<.001 ) , and TUG ( r=−.84 , P<.001 ) . An  FGA  score of ≤22/30 provides both discriminative and predictive validity . The FGA ( scores ≤22/30 ) provided 100 % Sn , 72 % Sp , LR+ of 3.6 , and LR− of 0 to predict prospect i ve falls . Limitations The study was limited by the length of time of follow-up and the small sample size that did not allow for evaluation of criterion scores by decade . Conclusions The FGA with a cutoff score of 22/30 is effective in classifying fall risk in older adults and predicting unexplained falls in community-dwelling older adults
