뇌파훈련이 지적장애인의 운동수행능력에 미치는 영향

Abstract

This study intends to figure out the relationship of brian function and motor competency which are important elements to the learning of the intellectually disabled to provide elementary materials so as to propose the teaching method for effective learning of the intellectually disabled. The subjects participating in the study were composed of minor-degree intellectually disabled persons attending the special class in H high school and residing in the city D, and according to the classification of intellectual disability from special education law for the disabled and such, their results of K-WISC-III intellect test before 18 showed IQ of 50~75, and the results for SQ were 55~74, with five persons each in the experiment group and control group allocated with simple random sampling. In order to verify the effect of motor competency according to participation in brainwave training program, both the experiment group and control group participated in the taekwondo training program 40 minutes each, 3 times a week, but the experiment group executed brainwave training for 20 minutes in the self-training mode using neuro-feedback under the instruction of the research and the special teachers. The measurement results were analyzed using the statistics software PASW Version 19.0K, and statistical significance level was configured to be .05. The mean (M) and standard deviation (SD) of pre-test and post-test of motor competency of experiment group and control group were calculated and compared, and to verify the uniformity of the groups, the independent samples t-test was executed against the pre-test. In order to verify the effect of brainwave training program while excluding the motor competency and brain function index before the execution of the experiment, the pre-test was set as the covariate and the covariance analysis (ANCOVA) was executed, and the adjusted mean value per group was calculated. Also, in order to find out the average change within the group participating in the experiment, the paired sample t-test was executed against the 8 weeks of experiment, and the following conclusion was drawn. Static coordination, hand motion coordination, normal motion coordination, simultaneous spontaneous motion, single motion competency of experiment group showed significant difference except for motor speed and total performance competency. As mentioned above, it is possible to draw improvements of brain function or motor competency of the intellectually disabled just with physical activities, but a more positive and faster effect can be expected when executed alongside brainwave training. Therefore, the improvement of brain function through brainwave training must be considered as an important factor of motor competency, and it appears necessary to search for various methods regarding the teaching methods of the intellectually disabled.
