| Résumé : | Background The measurement tool used for an accurate balance assessment should produce valid and reliable results in the population in which it is used. Objectives To examine whether two performance-based task tests are a reliable and valid measurement test to assess balance in patients with early and advanced knee osteoarthritis (KO). Design Reliability and concurrent validity research. Method Test-retest reliability by calculating the intraclass correlation coefficient (ICC) between the first and second trial periods of performance-based task tests (Alternate Step Test & Pen Pick up Test); their correlations with the Timed Up and Go Test (TUGT) were calculated and their concurrent validity in balance assessment were examined. Results A total of 100 patients (75% women, 25% men, mean 59 + 10 years) with KO, 50 early (54 + 7 years, 34 women, 16 men) and 50 advanced (64 + 9 years, 41 women, 9 men), participated in the study. The ICC values for the Alternate Step Test (AST) and Pen Pick up Test (PPT) in patients with early KO are 0.881 (0.747?0.939, 95% confidence intervals) and 0.815 (0.689?0.892, 95% confidence intervals), respectively, while it is 0.852 (0.752?0.913, 95% confidence intervals) and 0.861 (0.756?0.922, 95% confidence intervals) in patients with advanced KO. Pearson correlation coefficient between AST & PPT times and TUGT time in patients with early and advanced KO was in the range of 0.535?0.746 (p |
