The WorkHab Functional Capacity Evaluation (FCE) is widely used in Australian workplace injury management and occupational rehabilitation arenas; however, there is a lack of published literature regarding its reliability and validity. Purpose: This study investigated the intra- and inter-rater reliability of the manual handling component of this FCE. Method: A DVD was produced containing footage of the manual handling components of the WorkHab conducted with four injured workers. Therapist raters (n == 17) who were trained and accredited in use of the WorkHab FCE scored these components and 14 raters re-evaluated them after approximately 2 weeks. Ratings were compared using intraclass correlation coefficients (ICCs), paired sample t-tests (intra-rater), chi-squared (inter-rater) and percentage agreement. Results: Intra-rater agreement was high with ICCs for the manual handling components and manual handling score showing excellent reliability (0.94–0.98) and good reliability for identification of the safe maximal lift (ICC: 0.81). Overall inter-rater agreement ranged from good to excellent for the manual handling components and safe maximal lift determination (ICC > 0.9). Agreement for safe maximal lift identification was good. Conclusions: Ratings demonstrated substantial levels of intra-rater and inter-rater reliability for the lifting components of the WorkHab FCEs.
