The aim of this study was to determine test-retest reliability of a Functional Capacity Evaluation for patients with non-specific Work Related Upper Limb Disorders (WRULD FCE). The study sample included 33 healthy adults, consisting of 14 males and 19 females with a mean age of 29.2 years. The WRULD FCE consisted of 8 different tests including 26 items measuring repetitive movements, duration, working in awkward positions, forceful movements and static postures. Two FCE sessions were held with a 10-day interval. Means, 95% confidence intervals, one-way random Intraclass Correlation Coefficients (ICCs), 95% limits of agreement and repeated measures were calculated. An ICC between 0.75 and 0.90 was considered as good and an ICC above 0.90 was considered as an excellent reliability. The results showed that 14 of 26 items (54%) had excellent reliability, 9 of 26 items (35%) had good reliability and 3 of 26 items (11%) had moderate reliability based on ICC values. Significant learning effects were present in the Purdue Pegboard Task and in the Complete Minnesota Dexterity Test. It is concluded that the WRULD FCE is reliable in healthy adults.
