호흡근 강화 훈련 프로그램이 경직형 뇌성마비 아동의 구어산출에 미치는 효과

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the effect of respiratory muscles training by Proprioceptive Neuromuscular Facilitation (PNF) on improvement of speech production mechanism in children with spastic cerebral palsy. The effect were measured with electromyogram (EMG), changing rate of vital capacity and acoustic analysis of voice. The EMG were measuring device for respiratory muscles activation. The EMG signals were collected during the production of /a/ sound and resting state. The vital capacity was measured in maximal inspiration sections and maximal expiration sections. The evaluation for improvement of speech were acoustic analysis of voice sample. Voice sample were consisted of MPT for /a/ sound and reading a short sentence. The training of respiratory muscles took 10 weeks. Every 1 session took 40minute that was 3 times 1 week.The result were as follows: the respiratory muscles training by PNF increased on respiratory muscles activation that could known by increased on normalized EMG(%rest) values, vital capacity, Maximal Phonation Time and intensity of voice for all subjects. In conclusion, the respiratory muscles training by PNF was effective in improvement of speech production mechanism for children with spastic cerebral palsy.
