VeRSE: Vertical Reading Strategy Efficacy for Homonymous Hemianopia after Stroke: A Feasibility Study

Area of Science:

• Neuroscience
• Ophthalmology
• Rehabilitation Science

Background:

• Homonymous hemianopia is a visual field defect common after stroke.
• Reading difficulties are a significant challenge for stroke survivors with homonymous hemianopia.
• Vertical reading has not been previously studied in this population.

Purpose of the Study:

• To assess the feasibility of using vertical reading for stroke survivors with homonymous hemianopia.
• To evaluate the appropriateness of testing methods and outcomes.
• To determine recruitment potential for future studies.

Main Methods:

• A feasibility study employing a cross-over design.
• Involved stroke survivors diagnosed with homonymous hemianopia.
• Assessed reading speed in three directions: horizontal, 90° clockwise (downward vertical), and 90° anti-clockwise (upward vertical) in a randomized order.

Main Results:

• Seven participants with stroke-induced homonymous hemianopia were recruited (25.9% recruitment rate).
• Mean reading speeds were: horizontal (120.3 wpm), downward vertical (62.7 wpm), and upward vertical (74.6 wpm).
• Vertical reading speeds were significantly slower than horizontal reading speeds.

Conclusions:

• This feasibility study provides essential data for designing future research on vertical reading interventions.
• Future studies should prioritize reading acuity, considering both speed and accuracy.
• Preliminary studies incorporating a practice element are recommended to evaluate potential improvements over time.
