Background
No Arabic or its dialect questionnaire is available to evaluate the anterior knee pain in the Saudi Arabian religious population. This study aims to translate, adapt, and psychometrically validate the Knee Injury and Osteoarthritis Outcome Score (KOOS-PF) Patellofemoral scale in the Arabic language in Saudi Arabic dialect.
Method
Translation has been done as per standard guidelines. The questionnaire was administered to 95 patients to determine the psychometric properties including on two different occasions, with a 48-hour gap in-between; to ensure that their answers were reliable; 84 patients (88.4% compliance rate) responded for test and retest reliability, ceiling-floor effects, validity and other psychometric criteria.
Results
Cronbach’s alpha (internal consistency) and test–retest reliability was good and excellent (∞ = 0.81; ICC > 0.95). None of the items showed >30% floor or ceiling effect and the minimal detectable change was within the acceptable range (<30%). The KOOS-PF subscale showed a moderate correlation (−0.568) with pain-visual analog scale for its construct validity.
Conclusion
The Arabic dialect of KOOS-PFis reliable and valid to be used to evaluate isolated knee pain of patellofemoral origin in Muslim patients in Saudi Arabia.
Purpose: To find out overall, age and gender specific prevalence of low back pain (LBP) and its correlates in urban population. Methods: Present study was cross-sectional survey, by door-to-door visit, using multi-stage random sampling technique from Hisar urban geographical area. Pre-designed, validated self-reported questionnaire was used to record 14 variables, one variable was calculated and 4 variables were measured. Primary variable of interest was pain in low back area in the last 12 months. Data was analyzed using IBM-SPSS (21.0 version). Chi-square test was used to see the association between LBP and categories. If there was a significance, univariate and multivariate binary logistic regression was used to identify the correlates. Results: Data of 1540 subjects (response rate 72.2%; females 54.2%) aged 30 years or more from five localities out of six were used. Overall one-year prevalence of LBP was 19%. Female sex (OR 1.60), low education (1.95) and low fasting blood glucose (1.34) were identified as correlates of LBP. Abdominal obesity, not using ghee, low income, low social class, smoking, long sitting and sleeping time increased the prevalence of LBP. Conclusion: Increasing the physical activity/exercise and reducing sedentary behaviors may reduce the prevalence of LBP in this population.
Purpose The primary aim of this study was to translate a self-reported questionnaire (KOOS) from English to Urdu and then to see its internal consistency, agreement, test-retest reliability, and validity among primary OA knee patients. Methodology First, KOOS questionnaire was translated from English language to Urdu through standardized cross-cultural protocol. This translated version of KOOS was administered to 111 radiographically diagnosed primary OA knee patients at two times with 48-hour interval in-between. Cronbach's alpha, floor and ceiling effect, intraclass correlation coefficient (ICC), absolute agreement %, and Spearman correlation were used to fulfill our objectives. Results Average time to administer this questionnaire was 20 minutes. There was good internal consistency with Cronbach's alpha ranging from 0.7246 to 0.9139. The absolute agreement of each item between two tests ranged from 81.08% to 98.20%. Test-retest reliability was excellent (“r” ranged from 0.9673 to 0.9782). There was no ceiling effect; however less than 4% floor effect was seen in two subscales. There was significant difference that existed between different X-ray grades in all subscales meaning good content validity for disease prognosis. Conclusion The present results show that KOOS Urdu version is a reliable and valid measure for primary OA knee patients.
