Objective. The Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) measures the cognitive performance of persons with cerebrovascular accident(CVA). Although this assessment was developed and standardized in Israel, it is frequently used in the United States. The purpose of this study was to identify whether differences in performance on the LOTCA existed between Americans and Israelis who have had strokes. Additionally, this study was designed to compare the performance of persons with right CVA with the performance of persons with left CVA because the normative data for the LOTCA does not include separate information for these two groups.
Method. The LOTCA was administered to 25 Americans with CVA (19 right CVA and 6 left CVA) and 56 Israelis with CVA (26 right CVA and 30 left CVA).
Results. On the majority of LOTCA subtests, there were no significant differences between American and Israeli subjects. Only one subtest, Orientation to Time, revealed significant differences between Americans and Israeli subjects both for subjects with right CVA and subjects with left CVA. Examination of subjects with right CVA versus subjects with left CVA also indicated few differences. Only one subtest, Pegboard Construction, revealed significant differences between subjects with right CVA and subjects with left CVA for both American and Israeli subjects.
Conclusion. The LOTCA is an appropriate tool for occupational therapists to use in assessing Americans who have had strokes. In addition, for the most part, the subtests of the LOTCA assess cognitive-perceptual abilities that are not specific to the right or left cerebral hemisphere.
