Abstract
- Objectives. – To assess the test-retest reliability and the construct validity of a modified version of the Lequesne index.Methods. – Patients with symptomatic knee osteo-arthritis fulfilling the revised criteria of the american college of rheumatology completed the Lequesne index twice at a 3 h interval. Impairment outcome measures and patients’ perceived discomfort in walking and handicap were recorded. An item by item analysis was performed. Items having insufficient psychometric properties were excluded. Test-retest reliability was assessed using the intraclass correlation coefficient (ICC) and the Bland and Altman method. Construct validity was investigated using Spearman rank correlation coefficient and a factor analysis was performed.Results. – Eighty-eight patients were included. One question assessing pain (question IE) had a weak reliability (Kappa = 0.39) and was excluded. The test-retest reliability of the modified questionnaire was excellent (ICC = 0.95). Expected convergent and divergent correlations were achieved excepted for Vas pain and Vas handicap (0.46 and 0.40 respectively), and the “a priori” double stratification was confirmed by factor analysis, explaining 48.7% of the variance.Conclusion. – The modified form of the Lequesne index has sufficient psychometric properties to be used to assess pain and function in knee osteo-arthritis in a french population.
