이 연구는 경직형, 불수의운동형 및 실조형 뇌성마비 화자들을 대상으로 호흡, 발성, 공명, 조음 및 운율체계의 특성을 평가할 수 있는 다양한 과업 및 측정 방법들을 적용하여 뇌성마비 유형 간의 구어산출 하위체계별 특성을 비교하고자 하였다. 이를 위해 경직형 뇌성마비 화자 32명, 불수의운동형 뇌성마비 화자 17명, 및 실조형 뇌성마비 화자 10명을 연구 대상으로 선정하여 모음연장발화하기, 교호운동, 수세기 및 읽기의 4가지 평가 과업에 대한 13가지 하위항목 및 27가지 측정 변수를 분석하였다. 이 연구의 결론은 다음과 같다. 첫째, 뇌성마비 유형 간에는 호흡체계의 특성에서 유의한 차이가 없다. 둘째, 뇌성마비 유형 간에는 발성체계의 특성에서 전반적으로 유의한 차이가 없다. 셋째, 뇌성마비 유형 간에는 공명체계의 특성에서 유의한 차이가 없다. 넷째, 뇌성마비 유형 간에는 조음체계의 특성에서 전반적으로 유의한 차이가 있다. 다섯째, 뇌성마비 유형 간에는 운율체계의 특성에 유의한 차이가 없다. 결론적으로, 경직형, 불수의운동형 및 실조형 뇌성마비 화자들은 구어산출 하위체계 중 호흡, 발성, 공명 및 운율체계에서 전반적으로 유사한 특성을 나타내지만, 조음체계에서는 유형 간에 대체로 차이가 있는 경향을 나타낸다. The purpose of this study was to compare the characteristics of the subsystems for speech production by the types of Cerebral Palsy (CP) by applying various tasks and measurements that can evaluate the characteristics of respiratory, phonatory, resonant, articulatory, and prosodic systems. The subjects were 32 speakers with spastic CP, 17 speakers with athetoid CP, 10 speakers with ataxic CP, and 35 CP-free speakers. The experiment was conducted by analyzing 13 sub-items and 27 parameters in four tasks (prolonged vowel utterance, diadochokinesis, counting, and reading). The conclusions obtained from this study were as follows; First, there were significant differences between speakers with CP and those without, but there were no differences among the types of CP in the characteristics of the respiratory system. Second, there were significant differences between speakers with CP and speakers without CP, but there were no differences among the types of CP in the characteristics of the phonatory system. Third, there were generally similar characteristics between speakers with CP and those without, but speakers with athetoid CP tended to differ with CP-free speakers in two tasks (diadochokinesis and reading), and there were no differences among the types of CP in the characteristics of the resonant system. Fourth, there were significant differences between speakers with CP and CP-free speakers in the characteristics of the articulatory system. Among the types of CP, speakers with athetoid CP had differences with speakers with spastic CP, but speakers with ataxic CP had no differences with speakers with spastic and athetoid CP in diadochokinetic tasks. Fifth, there were significant differences between speakers with CP and CP-free speakers, but there were no differences among the types of CP in the characteristics of the prosodic system. In conclusion, speakers with spastic, athetoid, and ataxic CP had similar characteristics in the subsystems for speech production, but they tended to differ by tasks in the articulatory system.
