Purpose : The purpose of this study was to identify whether prism glasses could reduce unilateral spatial neglect for hemineglect with stroke.
Methods : This study was conducted in M hospital located in Seoul from May 2019 to February 2020. Ten subjects with stroke were selected who met the criteria for the study. Subjects were prescribed with 10 and 15 △ prism glasses. Unilateral spatial neglect was measured by the Albert test, the star cancellation test and the letter cancellation test.
Results : The baseline of Albert's test value was 19.0±3.94 and decreased to 15.70±5.68 and 11.60±6.17 for 10 and 15 △, respectively(p<0.050). The star cancellation test value increased from 32.68±9.19 to 46.07±10.64 and 54.64±12.91(p<0.050). The letter cancellation test value increased from 18.30±5.14 to 23.50±7.58 and 27.0±5.76(p<0.050). Prism adaptation treatment showed that unilateral spatial neglect decreased in all tests.
Conclusion : The prism glasses showed that there was effect on the reduction of unilateral spatial neglect. It is, therefore, thought that theunilateral spatial neglect with stroke could decrease with prism glasses.
