다운증후군 아동과 청소년의 슬관절 등속성 근력 특성 비교

Abstract

This study was to provide fundamental information of muscle strength training, gait, and gross motor movement through comparing and analyzing low limb isokinetic torque of children and adolescents with Down syndrome. The subjects were 8 children with Down syndrome and 8 adolescents with Down syndrome. The peak torque, average power, and total work were measured with Cybex 770 at the speed of 60 /sec and 180 /sec. The data were analyzed by SPSS. The conclusion were drawn as follows;1. The peak torque was decreased as angular velocity increasing.2. Muscle strength was unequal between left and right knee joint.3. Adolescents with Down syndrome were higher than children in the peak torque, average power, total work, and flexor/extensor ratio. Therefore, children and adolescents with Down syndrome had normal characteristics related with isokinetic strength. However, there are lots of possibility of injury during activities because of the imbalance between left and right leg and low flexor/extensor ratio.
