The Effects of Walking Combined with Active Range of Motion Exercises on Aerobic Capacity in Patients with Juvenile Dermatomyositis

Abstract

Objectives: Physical activity programs may be useful in the treatment of Juvenile Dermatomyositis (JDM). Therefore, we aimed to assess the effects of combined physical activity program on aerobic capacity, life quality and function in children with JDM. Methods: 27 children with JDM and 15 healthy children as a control group were included. In physical activity program, all patients performed both aerobic walking exercise (3 days/week/12 weeks) and active range of motion exercises (4 days/week/12 weeks). All patients completed the childhood health assessment questionnaire (CHAQ). Range of motions (ROM) measurements of joints were performed by using universal goniometer. Aerobic capacity was determined by measuring peak oxygen uptake (VO2peak) during a cardiopulmonary exercise testing (CPET). Results: Before and after physical activity program peak oxygen uptake were significantly lower in patient group than in control group. After physical activity program, certain cardiopulmonary exercise testing parameters of JDM patients significantly improved. Peak oxygen uptake was found to be significantly increased following physical activity program in JDM patients. Also time-to-exhaustion was significantly increased after physical activity program. Physical activity program significantly improved CHAQ score in patient group. Conclusions: As well as improving life quality and function, aerobic walking combined with active range of motion exercises improve aerobic capacity of patients with JDM.
