RESUMEN
Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease in children. An intra-articular corticosteroid injection (IAS), one of the cornerstones of treatment for this disease, is usuaLLy associated with anxiety and pain. A major part of the success in reducing the pain is associated with the level of the child's anxiety even before starting the procedure. This is a case study of a 5 year old girl with JIA, who has been treated with an intra-articular corticosteroid injection to her knee joint. The case study is presented from the point of view of the medical clown, who is an important integral part of the team of the IAS procedure. In this article we will discuss the participation of medical clowns in the treatment of children in general, and in the IAS procedure in particular. The importance of the subject stems from the fact that it has been proven that the presence of medical clowns significantly alleviates the children's anxiety and pain. This study, as well as others on this subject, shows that we should encourage medical clowns as an integraL part of the treatment of children.
