The aim of our work was to identify gradient of the muscle fatigue of some muscle groups, among children with chronic juvenile arthritis, which are restricted in function by existing limitation in range of motions. Four patients in age of 9,5, with mentioned diagnosis were examined. Healthy subjects, with same ages were control group. Manuel muscle test, range of motion test and EMG examination were performed. Results shown significance difference in degree of muscle fatigue among observed patients, which explain decrease of muscle efficiency and must be taken when intensity of kinesitherapic treatment has to be done. It is concluded that structural changes on locomotory system induce secondary hypertrophy or atrophy of the muscle system and increase of muscle fatigue when activity of certain muscles is performed.
