Do digital test parameters (such as completion time, search speed, and search patterns) provide additional clinical information beyond conventional test scores? Researchers will compare the results of the web-based tests with standard paper-and-pencil tests to evaluate their diagnostic accuracy and clinical validity.\n\nParticipants will:\n\nComplete conventional paper-and-pencil Star Cancellation and Line Bisection tests Perform web-based (digital) versions of the same tests using a tablet and stylus Undergo routine clinical and cognitive assessments as part of standard care Provide demographic and clinical information",[80,81,82],"Stroke","Spatial Neglect","Spatial Neglect After Stroke",[84,81,85,86,87,30,36,88],"Visuospatial Neglect","Stroke Rehabilitation","Digital Assessment","Web-Based Assessment","Neuropsychological Testing","NOT_YET_RECRUITING","2026-04-12",{"date":92,"type":93},"2026-04-20","ACTUAL",{"date":95,"type":76},"2026-04-15",{"date":97,"type":76},"2026-12-01",{"name":5,"class":6},1]
