Difference in impact of neurobehavioural dysfunction on Activities of daily living performance between right and left hemispheric stroke.

Abstract

To explore whether persons with right- and left-sided cerebrovascular accidents differ significantly in mean impact of neurobehavioural impairments on ability to perform activities of daily living. Retrospective study of data from 215 persons (103 right-sided, 112 left-sided cerebrovascular accident). The Activities of daily living-focused Occupation-based Neurobehavioral Evaluation was used to evaluate ability on an activities of daily living scale and the impact of neurobehavioural impairment on ability on another scale. To control for possible differences in activities of daily living ability between groups, analysis of covariance, with activities of daily living ability as a covariate, was used to test for a significant difference in impact of neurobehavioural impairments on activities of daily living ability between groups. Expected moderate correlation (r = -0.57) was obtained between activities of daily living ability and neurobehavioural impact measures, and there was no difference in mean neurobehavioural impact measures between groups (F [1, 212] = 2.910, p = 0.090). This study is the first to explore directly the impact of neurobehavioural impairment on activities of daily living ability. While persons with right-sided and left-sided cerebrovascular accidents may differ in type of neurobehavioural impairments, direct evaluation of the impact of such impairments on activities of daily living ability reveals no difference between groups.
