Background The importance of exercise is remarkable in children with Juvenile Idiopathic Arthritis (JIA). ClinicalPilatesTherapy don’t generatefatigue,help inhibition of pain with respiratorycontrol and muscle spasm.This exercise model is entertainingand can be appliedas a group. Even though clinical pilates therapy is used on adult rheumatic patients, there is no study in JIA. Objectives To investigate the effects of Clinical Pilates Therapy on daily living activities and motor function in patients with JIA. Methods The study included 9 children (8F;1M) with JIA.After obtaining demographics, Childhood Health Assessment Questionnaire (CHAQ) was performed to evaluate daily living activities of children. Sedimentation rate (ESR) and C-reactive protein(CRP) were recorded. Bruininks-Oseretsky Test of Motor Proficiency (BOTMP) was applied to assessment the motor function. The same assessments were repeated after treatment.Therapy sessions were done three times a week. A session was included warm-ups,the main workout and cool down.Therapy sessions were done three times a week, two times a day, two weeks, each session lasting one hour. The warm up exercises included the warm up exercises of clinical pilates exercises and light – intensity dance. The main exercises consisted of clinical pilates exercises and the cool down exercises consisted of the cool down exercises of clinical pilates and body image affirmation exercises with dance figures (this method is named as Clinical Pilates Therapy by Edibe Unal). Results The mean age was 11,11±2,47 years. The mean duration of disease was 5,22±2,72 years. 5 oligoarticuler and 4 polyarticular type JIA were included. After the treatment,there were significant improvements in BOTMP scores(P 0,05). Conclusions It was concluded that clinical pilates therapy was shown positive effects on motor function in patients with JIA. But we considered that the application of this method in two weekly is not sufficient to show an effect on daily living. We assured that this method should be investigated on a larger patient group and in a longer period to obtain further effects. As a result, Clinical Pilates Therapy can be considered as reliable and safety exercise model in children with JIA to improve motor function in a short period. References Boros, C. and B.
