Persian translation and validation of the Kujala Patellofemoral Scale in patients with patellofemoral pain syndrome.

Disabil Rehabil 2012 27;34(26):2259-63. Epub 2012 May 27.

Musculoskeletal Rehabilitation Research Center, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran.

Purpose: To culturally translate and validate the Persian version of Kujala Patellofemoral Scale (KPS) and evaluate the test-retest reliability, internal consistency, construct validity and ceiling or floor effects of this instrument in patients with patellofemoral pain syndrome (PFPS).

Method: After standard forward and backward translations, 100 patients with PFPS completed the Persian versions of the KPS and Short-Form 36 Health Survey (SF-36) in the first visit. With time interval of 2-3 days after the first visit, 47 patients filled out the KPS in the second visit. Test-retest reliability and internal consistency were assessed using intraclass correlation coefficient (ICC(2,1)) with 95% confidence interval (95% CI) and Cronbach's α coefficient, respectively. The Spearman's rank correlation (r(s)) was used to assess the correlations between the Persian KPS and SF-36 subscales.

Results: The acceptable level of ICC >0.70 (ICC = 0.96, 95% CI = 0.93-0.98) and Cronbach's α coefficient >0.70 (α = 0.81) was obtained for the Persian KPS. There were low to moderate correlations (r(s) = 0.25-0.60, p < .01) between the Persian KPS and Persian SF-36 subscales of mental and physical health components. However, correlations between the Persian KPS and SF-36 physical components were higher than correlations between the Persian KPS and SF-36 mental components. No ceiling and floor effects were seen for the Persian KPS.

Conclusions: The Persian version of KPS is a reliable and valid outcome measure of disability and seems to be a suitable instrument for use in clinical practice of Iranian patients with chronic PFPS.

Validation of the Persian version of Functional Index Questionnaire (FIQ) and Modified FIQ in patients with patellofemoral pain syndrome.

Physiother Theory Pract 2013 Oct 30;29(7):521-30. Epub 2013 Jan 30.

Musculoskeletal Rehabilitation Research Center, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran.

The aim of this investigation was to culturally translate and validate the Functional Index Questionnaire (FIQ) and Modified FIQ (MFIQ) in patients with patellofemoral pain syndrome (PFPS). A sample of 100 patients with PFPS completed the FIQ and MFIQ, and Short-Form 36 (SF-36) Health Survey in the first session. The FIQ and MFIQ were re-administered to a sample of 47 patients to evaluate test-retest reliability. Read More
