Abstract

This study was performed to examine the presence of dysphagia and analyze characteristics of the symptoms in cerebrovascular accident(CVA) patients without awareness of dysphagia. A questionnaire for this study was given to CVA patients who had visited P rehabilitation medical center in Busan. Eleven patients (4 males and 7 females) who answered no awareness of dysphasia were given to VFSS, functional dysphasia scale, and NCSE. Descriptive statistics and Pearson correlation analysis were performed by SPSS 12.0. All of subjects without awareness of dysphasia showed characteristics of dysphasia symptoms. Prominent dysfunctions were problems in oral phase and delay of swallowing reflex in pharyngeal phase. For the aspect of cognition, they showed lower score in construction, memory, and similarity than other NCSE items. There was highly significant correlation between orientation, judgment and delay of swallowing reflex. Verbal comprehension and residual materials in oral cavity showed closed correlation. CVA patients without awareness had dysphagia with high probability. The early evaluation of dysphagia should be performed in CVA patients in order to prevent complications due to CVA, so it is necessary to increase the effectiveness of rehabilitation therapy.

본 연구는 연하장애에 대한 병식이 없는 뇌졸중 환자들에서 연하장애의 유무와 양상을 알아보고자 시행되었다. 부산시에 소재하고 있는 P 재활의학병원을 내원한 뇌졸중 환자들 중 설문지 조사를 통하여 병식이 없다고 응답한 11명의 환자(남자 4명, 여자 7명)들을 최종대상으로 선정하였다. 설문지 조사, 비디오 투시 연하 조영 검사(video-fluoroscopic swallowing study, VFSS), 기능적 연하곤란 척도, 신경행동학적 인지상태 검사(neuro- behavioral cognitive status examination, NCSE)를 실시하였다. 결과 분석은 SPSS12.0을 사용하여 기술통계와 피어슨 상관분석을 하였다. 본 연구의 대상 뇌졸중 환자들 중 연하장애에 대한 병식이 없다고 응답한 환자들은 모두 연하장애를 동반하였다. 동반되는 연하장애의 양상으로는 구강기의 문제들과 인두기의 삼킴반사 지연이 있으며 인지적 특성에 있어서는 NCSE 항목 중 구성력, 기억력, 유사성이 다른 항목들보다 더 낮은 것으로 나타났다. 기능적 연하곤란 척도와 NCSE 항목들 간의 상관관계를 살펴본 결과 지남력과 판단력이 삼킴반사 지연과 언어이해가 구강 내 식괴의 잔여정도와 유의한 상관관계가 있었다. 본 연구의 결과에 의하면 연하장애에 대한 병식이 없는 뇌졸중 환자들이 연하장애를 가질확률이 높다. 따라서 연하장애로 인한 합병증을 예방하고 작업치료의 효과를 높이기 위해 뇌졸중 환자들에게 조기에 연하장애 평가가 이루어져야 할 것이다.
