본 연구는 고유수용성 신경근 촉진법을 이용하여 호흡에 관여하는 근육들을 도수(manual)로 직접 촉진함으로써, 뇌성마비 아동들이 정상적이고 적절하게 호흡근육을 사용하도록 도와주고, 정상적인 호흡 패턴을 경험하도록 하여 그에 따른 호흡량의 증가로 구어산출의 개선을 얻고자 하는데 그 의의를 두었다. 이에 3명의 경직형 시지마비 남자 아동을 대상으로 구어산출의 개선 정도를 최대연장발성, 발성강도 및 음도범위 등으로 분석 해 보았다. 실험은 호흡근들을 집중적으로 촉진하는 기법들로 프로그램을 구안하여 적용하였고, 평가는 근전도, 폐활량측정기기 및 음성샘플의 음향학적 분석으로 하였다. 호흡근 강화를 통해 호흡근 근력의 증가 및 폐활량이 증가하였고, 그에 따른 최대연장발성 시간이 길어졌으며 발성 강도의 변화도 나타나는 결과를 보였다.

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.
