The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) Ultrasound Committee ran a workshop during the annual GRAPPA meeting that was held in July 2020. The group presented the following 3 topics: (1) the transition from psoriasis to PsA and the role of US; (2) the effect of biomechanical forces on the entheses in health and disease, and insight for PsA pathogenesis; and (3) differentiation of enthesitis from pain sensitization: use and limitations of clinical and sonographic evaluation of enthesitis. This article summarizes the key messages from this workshop. ER -
