Summary

The goal of this observational study is to evaluate the clinical usability and diagnostic performance of newly developed web-based Star Cancellation and Line Bisection tests in assessing visuospatial neglect in hemiplegic stroke patients. It will also compare these digital tests with conventional paper-and-pencil assessments.

The main questions it aims to answer are:

Can the web-based Star Cancellation and Line Bisection tests accurately distinguish between stroke patients with and without visuospatial neglect? 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.

Participants will:

Complete 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

Conditions

  • Stroke
  • Spatial Neglect
  • Spatial Neglect After Stroke

Interventions

DIAGNOSTIC_TEST

Web-Based Star Cancellation Test

The intervention consists of a web-based Star Cancellation Test developed by the study investigators for the assessment of visuospatial neglect. This test is implemented as a browser-based application that can be accessed on standard devices without requiring software installation and is administered using a tablet and stylus pen to ensure consistent interaction. The digital Star Cancellation Test is based on the conventional paper-and-pencil version and includes both target and distractor stimuli. In addition to standard scoring, it automatically records performance measures such as the number of omitted targets, laterality index, completion time, search speed, and search path characteristics.

DIAGNOSTIC_TEST

Web-Based Line Bisection Test

The intervention consists of a web-based Line Bisection Test developed by the study investigators for the assessment of visuospatial neglect. This test is implemented as a browser-based application that can be accessed on standard devices without requiring software installation and is administered using a tablet and stylus pen to ensure consistent interaction. The digital Line Bisection Test follows the conventional paradigm in which participants are asked to mark the midpoint of horizontal lines. In the digital version, line positions vary across trials, and deviation from the true midpoint is calculated automatically, along with measures of variability.
