| Research Abstract |
Unilateral spatial neglect (USN) is a common syndrome in which a stroke patient fails to report or respond to stimulation from the side of space opposite a brain lesion, where these symptoms are not due to primary sensory or motor deficits. Unilateral spatial neglect (USN) is most damaging to a stroke patient who also has a lower performance in their activities of daily living. The purpose of this study was to understand more accurately pathology of USN using a new HMD system in the object-centered co-ordinates and egocentric co-ordinates system by use of a research method of Assistive Engineering. In addition, the study was to analyze the effect of transformed visual real image and visual stimulation in order to reduce ignorant area. The results showed that the assessment of USN using the HMD system may clarify the left neglect area which cannot be easily observed in the clinical evaluation for USN. According to the result of the use of reduced image condition and the arrows condition by HMD system, these line cancellation scores more increased than the score of the common test. HMD can produce an artificially versatile environment and might be effect for improving ignorant by visual stimulation as compared to the common clinical evaluation and treatment.
