The purpose of this study was to investigate the characteristics of cognitive development and motor development in children with developmental delays. Subjects were 43 children with a mean corrected age of 19.19 month (SD=7.48). The Gross Motor Function Measure (GMFM) and the Bayley Scale of Infant Development-second edition (BSID-II) were administered to the total children. Statistical analysis was done by paired t-test and Pearson correlation, using SPSS software. The results were as follows: 1) Most of the children with developmental delays showed statistical delays on the mental scale rather than on the motor scale. 2) The correlation coefficients of cognitive performance and motor performance were ranged between r=.38 and r=.83 in children with developmental delays. 3) Lower motor performance showed significant association with lower cognitive score. The findings suggest that cognitive and motor performance in children with developmental delays was significantly correlated.

목적 : 연하곤란이 있는 환자에게 목에 붙이는 전극을 통하여 전기자극을 주는 신경근 전기자극 치료의 안전성과 치료효과를 알아보기 위함이다. 연구방법 : 연하곤란 증상이 있는 10명을 대상으로 2주일 동안 1주일에 5번, 하루에 한 시간씩 신경근 전기자극 치료를 하였다. 전기자극 치료 시작 전․후에 비디오 투시조영연하검사로 환자가 흡입 없이 삼킬 수 있는 음식물의 형태를 근거로 삼킴 기능 점수를 최소 0점에서 최고 6점까지 주었으며 삼킴 기능에 관련된 임상증상을 치료 전과 치료 후로 평가하여서 Wilcoxon 부호 순위검증으로 비교 분석하였다. 결과 : 삼킴 기능 점수는 1.6점에서 4.4점으로 유의하게 증가되었으며(p＜0.05), 환자의 90%에서 삼킴 기능이 증가하였다. 또한 삼킴 기능에 관련된 구토반사, 기침반사, 혀의 운동성, 후두 편위가 신경근 전기자극 치료 전에 비하여 치료 후에 유의하게 회복하였다. 결론 : 신경근 전기자극 치료는 목의 삼킴 기능에 관련하는 근육을 활성화시키는 것뿐만 아니라 삼킴 기능에 영양을 미치는 임상적 증상의 회복에도 도움이 되므로 연하곤란을 치료하기 위한 신경근 전기자극 치료는 안전하고 효과적인 것으로 입증되었다.

The purpose of this study was to identify the relationship between motor and mental status and functional status, and to determine appropriate test times. Using the Modified Motor Assessment Scale(motor status) and the Modified Barthel Index(functiona1 status), the Glasgow Coma Scale(menta1 status), we tested 9 stroke patients. 1 week. 1 month after their stroke. Three measures are reliable and valid. We used the Sperman correlation coefficient(r) and Wilcoxon signed rank test to analyze the data. MMAS scores at 1 month correlated significantly with MBI scores at 1 month(r=0.89). But GCS scores at 1 month did not correlate significantly with MBI scores at 1 month. All data of MMAS at 1 month correlated significantly with MBI scores at 1 month. But only verbal response score among GCS scores at 1 month correlated significantly with MBI scores at 1 month(r=0.86). The difference of MMAS, GCS. MBI scores between 1 week and 1 month after stroke onset were statistically significant(p(0.05). This study suggested that the mental status had more impact on functional recovery than motor status at 1 week after their stroke. Also, the motor status had more impact on functional recovery than mental status at 1 month after their stroke. But the mental and motor status should be considered together in predicting the functional recovery status of stroke patients.
