PURPOSE: We examined whether adding the CT findings to the impairment and the disability scales enhances the prediction of stroke outcome.
METHODS: The subjects were 200 stroke patients (126 males and 74 females, average age 62.4 y/o) over 1 month after stroke onset. The site of the brain lesion was classified into the 34 areas in CT. The Stroke Impairment Assessment Set (SIAS) and the Functional Independence Measure (FIM) were measured at admission and discharge. The FIH at discharge was predicted using artificial neural network software in 100 patients with two patterns of independent variables. The first pattern was the SIAS and FIM at admission (non-CT pattern) and the second pattern was the SIAS, FIM, and the CT lesion (CT pattern).Data from another 100 patients were applied to the created network and the correlation coefficients between observed and predicted FIM were calculated.
RESULT and CONCLUSION: The correlation coefficient of CT patterns was higher than the one of non-CT patterns. In conclusion, the CT findings can increase the preciseness of outcome prediction in stroke patients.

DIASCHISIS AND FUNCTIONAL RECOVERY IN STROKE PATIENTS
Woo-Kyoung Yoo, Joong-Sun Chon, Se-Il Chun (Yonsei University, Seoul, Korea)
Purpose: To find out the functional recovery in stroke patients according to the presence of diaschisis.
Method: CT and/or MRI scan and SPECT study were performed on a consecutive series of 98 in-patients from July 1995 with the exclusion of patients of cerebellar, pontine, and bilateral hemispheric lesions. Therefore, 42 stroke patients were included in this study.
Result: 1) The types of diaschisis were crossed cerebellar diaschisis (CCD) (36 cases), thalamocortical diaschisis (6 cases), striatocortical diaschisis (5 cases), and capsulocortical diaschsis (1 case). 2) The functional recovery scale improved from 37.5 points to 53 points by the motricity index and from 41.2 points to 68.8 points by the MBI score. 3) Only the motricity index showed a significant inverse correlation with the asymmetry index in CCD.
Conclusion: Although other types of diaschisis were found, the most frequent type was CCD. The lower the asymmetry score, the lower was the motricity index. Therefore, CCD could be one of prognostic factor for functional recovery.
