Abstract
The impact of hemispatial neglect on wheelchair navigation was investigated using a wheelchair obstacle course. The results replicated the findings of Webster et al. (1988): Right-CVA patients with hemispatial neglect (n = 25) struck more objects on their left and ran directly into obstacles placed in their path (p < .0001). Right-CVA patients who did not omit left-space targets on letter cancellation (n = 23) did not run directly into obstacles; however, they did sideswipe more obstacles and struck more left-sided obstacles than did left-CVA (n = 20) and nonpatient controls (n = 19; p < .0001). Both hemi-neglecting patients and right-CVA patients who committed left-space sideswipes (n = 12) evidenced attentional bias to right space, as measured by more rightward starting points on letter cancellation and the Rey-Osterreith Complex Figure copy (p < .0001).
