[Purpose] The purpose of this study was to establish the reliability and validity of Upper Limb Functional Index (ULFI), which has been translated into Korean, in treating patients with upper limb complaints. [Subjects and Methods] Fourty-nine subjects with upper limb disorder, 20 males and 29 females, participated in this study. Reliability was determined by using the intra class correlation coefficient and Cronbach’s alpha for internal consistency. Validity was examined by correlating ULFI scores with Disability of Arm, Shoulder and Hand (DASH). [Results] Test-retest reliability was 0.90. The criterion-related validity was established by a comparison with the Korean version of DASH. [Conclusion] The Korean version of ULFI was shown to be a reliable and valid instrument for assessing upper limb complaints.
