연구목적: 본 연구는 경직형뇌성마비아동의 상지 기능에 대해 패턴화된 감각 증진(PSE) 음악의 복잡성 수준이 미치는 영향을 알아보기 위해 시행되었다. 연구방법: 실험은 경직형 뇌성마비 아동 10명을 대상으로 동일 기관에서 개별적으로 실시되었다. 피험자는 무음악(사전), 단순 PSE 음악, 복잡 PSE 음악, 무음악(사후) 등의 조건에 따라 어깨관절 굴곡, 팔굽관절 신전, 아래팔 회외, 수근관절 신전의 ROM 및 장악력 등 다섯 가지의 동작을 무선순위로 수행하였다. 연구결과: 각 과제 수행률을 비교 분석한 결과, 상지 ROM은 PSE 음악이 있을 때 즉각적 향상 효과를 보였고, 복잡 PSE 음악 조건에서 더 큰 변화가 나타났으나, 변화의 폭이 통계적으로 유의하지는 않았다. 장악력 과제에서는 복잡 PSE 음악을 들었을 때 단순 음악 조건에 비해 통계적으로 유의미한 차이를 보였다(p<.05). 결론: 실험의 결과를 통해 음악요소의 복잡성이 큰 PSE 음악이 대상자의 상지 기능 변화에 즉각적인 영향을 준다는 것을 알 수 있었다. 본 연구 결과는 경직형뇌성마비아동의 신체 재활에 제공되는 PSE 음악 구성에 대한 기초 자료를 제시한 것에 의의가 있다.
Purpose: The aim of this study was to investigate the effect of patterned sensory enhancement(PSE) music on the upper limb function of children with spastic cerebral palsy. Method: A total of 10 children recruited from a rehabilitation welfare center participated in this study. While performing five tasks including shoulder flexion, elbow extension, forearm supination, wrist extension, and gripping, PSE music was played for the subjects. Results: The results showed that a significantly increased range of motion and grip strength were found in all subjects with the immediate use of PSE music(p<.05), and additional functions were promoted in the complex form of the music. Conclusion: This study implies that the complexity of musical elements in PSE music for upper limb motion immediately leads to significant improvement in ROM and grip strength by providing sufficient temporal, spatial, and dynamic information for expected motor functions.
