A simple method to dissociate sensory-attentional and motor-intentional biases in unilateral visual neglect.
A variant of a line bisection test was devised. Patients with unilateral visual neglect and control subjects were asked to perform the test, which consisted of two subtasks: a verbal and a manual task. The verbal task was newly designed and did not require manual responses from the subjects. The manual task was similar to conventional line bisection tasks. This paper reports and discusses the results obtained from each task and their correlations. This technique is compatible with bedside examinations, does not require a complex apparatus, and provides useful data for the assessment of unilateral visual neglect.
