Abstract:

The Upper Extremity Functional Index (UEFI) is frequently used to evaluate patient s with upper limb disorders, but it has not been translated and validated in Urdu. Objective: The purpose of this project was to translate and cross-culturally adapt UEFI into Urdu (UEFI-U) while also investigating its psychometric measurements. Methodology: The original version of the UEFI was translated and cross-culturally adapted in accordance with established international norms. At baseline, all participants were requested to fill the UEFI-U, 36-item Short Form Health Survey (SF-36), Visual analogue scale for pain (VA Spain) and Visual analogue scale for disability (VAS disability) and three weeks after receiving the intervention again requested to patient's group to respond these questionnaires along with the Global rate of change scale (GROC). The UEFI-U was assessed for factor analysis, reliability, content validity, construct validity (discriminative & convergent validity) and responsiveness. Results: The UEFI-U had an internal consistency of 0.93, according to Cronbach's alpha. The total UEFI-U has excellent test-retest reliability, as evidenced by its ICC2,1 = 0.91. The UEFI-U has a unidimensional structure, constituting 75.18% of total variance. There was no floor or ceiling effect found for the total UEFI-U score. Pearson's correlation coefficient showed a moderate association with SF36 physical function (r=0.68), SF36 role physical (r=0.60), VAS pain (r=-0.54) and VAS disability (r=-0.57) but fair association with SF36 bodily pain (r=0.42). A significant difference (p<0.001) in UEFI-U total score was found between patients and healthy controls. Conclusion: The findings revealed that UEFI-U is a reliable, valid, and responsive questionnaire to assess disability in Urdu-speaking population having upper extremity disorders.
