Background Psoriatic arthritis (PsoA) is a chronic inflammatory disease that can produce varying degrees of functional capacity. High proportion of patients refers affected peripheral joints, being foot and ankle between the locations described. There are many different methods to assess functional disability. To assess the general status of functional disability different questionnaires are available, as “Health Assessment Questionnaire” (HAQ), and to assess functional disability in foot and ankle there are different scores as the “Foot Function Index” (FFI).

Objectives The purpose of this study is to analyze the relation between general functional disability using HAQ and foot and ankle specific functional disability using FFI in psoriatic arthritis patients.

Methods We included 96 PsoA patients with peripheral affectation from the Rheumatology Department of HUP La Fe, who underwent a functional disability evaluation using the HAQ and FFI questionnaires. A beta regression model was used for statistical analysis.

Results The 96 PsoA patients scored an HAQ average of 0.57 (0-3) and a FFI average of 15.9% (0-100%). There is a statistically significant association (p<0.001) between HAQ and FFI. Furthermore, there is a statistically significant association (p<0.001) among all different subparagraphs of FFI (pain, disability and loss of function) with HAQ.

Conclusions A strong general status of functional disability is correlated to high functional disability in foot and ankle. We therefore believe that the FFI score is a valid and reliable tool to assess foot and ankle functional disability in PsoA patients.
