Assessment of sensory neglect: a study using moving images

A novel modified passive line-bisection test was performed using a computer display with a moving image. In the test, the subjects were required to give verbal responses instead of limb movements. The test, consisting of two subtasks, left-to-right and right-to-left tasks, was applied to patients with unilateral neglect and controls. The patient group showed an obvious mean deviation in both tasks, and showed greater rightward deviation in the right-to-left task than in the left-to-right task. The control group showed little differences between the two tasks. This paper discusses the results obtained from the two different conditions and their correlations. This method provides useful data for the assessment of unilateral neglect.
