AB  - BACKGROUND: The proper reliability analysis for specific type of data and limit 
      study of various types of construct validity are crucial for performance-based 
      tests for the knee osteoarthritis (OA) population. The purpose of this study was 
      to evaluate relative and absolute reliability and construct validity of the 
      Osteoarthritis Research Society International (OARSI) recommended minimal core 
      set of performance-based tests in knee OA in community-dwelling adults. METHODS: 
      Fifty-five primary knee OA (median age 69.0, interquartile range [IQR] 11.0) 
      participated in the cross-sectional study. Three performance-based tests were 
      performed in two sessions with a 1-week interval; 30-s chair stand test, 40-m 
      fast-paced walk test and 9-step stair climb test. Relative reliability included 
      intra-class correlation and Spearman's correlation coefficient (SPC). Absolute 
      reliability included standard error of measurement, minimum detectable change, 
      coefficient of variance, limit of agreement (LOA) and ratio LOA. Knee Injury and 
      Osteoarthritis Outcome Score-Physical Function Short Form (KOOS-PS), knee 
      extensor strength and pain scale were analysed for convergent validity using 
      Pearson's correlation coefficient and SPC. Analysis of Covariance was utilised 
      for known-groups validity. RESULTS: Relative and absolute reliability were all 
      acceptable. LOA showed small systematic bias. Acceptable construct validity was 
      only found with knee extensor strength. All tests demonstrated known-groups 
      validity with medium to large effect size. CONCLUSION: The OARSI minimum core set 
      of performance-based tests demonstrated acceptable relative and absolute 
      reliability and good known-groups validity but poor convergent validity.
