A study of assessment of unilateral spatial neglect using a system for motion analysis of eyes and a head-neck

We designed a simultaneous analysis system to measure eye and head-neck movement in the evaluation of unilateral spatial neglect (USN). Analysis was performed in one healthy subject and one USN patient with left homonymous hemianopsia. Synchronization of eye and head-neck movement enabled quantitative and qualitative analysis of these movements. Future studies are required to enhance the accuracy of measuring eye movement angles, to quantitatively evaluate neglect fields, and to confirm the usefulness of this system in USN patients.
