Persian Translation, Internal Consistency and Reliability of Wolf Motor Function Test

Background: Wolf Motor Function Test (WMFT) is used in the assessment of upper extremity motor function in stroke patients. This scale contains 15 items and assesses joint-segment movements and functional tasks. Objectives: Translation and assessment of internal consistency and reliability of the Persian version of WMFT in Iranian stroke patients. Materials and Methods: After translation (based on the international quality of life assessment method), the Persian version of WMFT was used in 56 stroke patients. Item-level internal consistency was assessed using Spearman’s correlation, reliability in frequent tests using Intraclass Correlation Coefficient (ICC), and internal consistency using Cronbach s alpha coefficient. Results: Translation was simple in 94.4% of items, and the quality of translation was favorable in 89.7% of cases. A high correlation was observed between the most of items and total WMFT score. Based on ICC, reliability in frequent tests was high (from 0.97 and 0.99). Internal consistency was 0.78 in scores obtained. Conclusion: The Persian version of WMFT has a favorable reliability for use in the assessment and development of rehabilitation programs for improving functional abilities of upper extremities in Iranian stroke patients.
