Abstract:
Knee Osteoarthritis (KOA) and aging are conditions that can compromise physical function and quality of life of human being. Thus, performance-based tests and specific self-reported measures related with KOA and general health-related quality of life (QoL) should be used in clinical intervention with elderlies. The study aim was to investigate which factors best predict the performance of the Timed “up-and-go” test in the elderly people with KOA. Eligibility criteria were age ≥ 60 years and uni or bilateral KOA. Subject performed physical tests [Timed “up-and-go” (TUG), Six Minutes Waking Test (6MWT), Five Repetition Sit-to-Stand Test (FRSTST)], Handgrip, 6 meters gait speed, Standing Balance], and filled self-reported questionnaires [Knee Injury and Osteoarthritis Outcome Score (KOOS), health-related quality of life (EQ-5D-5F) and International Physical Activity Questionnaire (IPAQ)]. Pearson and Spearman coefficients were used for correlation analysis and multiple linear regression
analysis to identify the significant predictors of Timed “up-and-go”. Results: Final sample included 67 patients, 69±6 years of age. Timed “up-and-go” can be explained by two models. The best model (explained 80.7% of variance) included FRSTST, 6MWT, Gait Speed, KOOS ADL and EQ-5D-5F Self-Care variables. Conclusion: Functional strength, mobility, gait speed, and perceived limitation in activities of daily living influenced the TUG performance.
