Assessment tools in psoriatic arthritis: A review

Psoriatic arthritis is a chronic inflammatory arthritis associated with psoriasis. Its clinical presentation is diverse and heterogeneous with a spectrum of axial, peripheral and extra-articular involvement (dactylitis, enthesitis, skin psoriasis, nail disease). Clinimetric tools including simple and composite domains have been designed and used in clinical trials and clinical practice. In recent years, there has been much progress in the development of assessments tools, these provide an objective measure of disease activity and treatment response involving clear benefits if applied in routine clinical practice. This paper presents a thorough and up-to-date review of clinimetric tools for psoriatic arthritis reported in the literature.
