다운증후근 아동과 청소년의 슬관절 등속성 근력 특성 비교 = The Comparative Study of Knee Extensor and Flexor Isokinetic Strength in Children and Adolescents with Down Syndrome

다국어 초록 (Multilingual 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 0f 60˚/sec and 180˚/sec. The data were analyzed by SPSS. The conclusions 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 that 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 possibilities of injury during activities because of the imbalance between left and right leg and low flexor/extensor ratio.
