Exploring the potential of augmented reality in rehabilitation: a novel approach for post-stroke unilateral neglect.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: Unilateral neglect affects up to 80% of right hemisphere stroke survivors and poses a significant barrier to rehabilitation. It is a strong predictor of poor prognosis and leads to prolonged hospital stays, yet no established treatment currently exists. Methods: We propose an innovative approach, NeuroNavAR, a novel treatment method that utilizes neural network models to train the human nervous system under the guidance of augmented reality (AR). This method focuses on an AR-enhanced smart training program specifically for post-stroke spatial neglect. While the current implementation runs on a GPU server for technical validation, the application is designed for future deployment on Android and iOS devices. It employs image processing algorithms to identify real-world objects, such as clocks and chairs, segment their contours, and generate virtual bee patterns. These virtual bees navigate along the contours of the objects, and patients are encouraged to follow the bee patterns, receiving rewards upon completing a cycle. If patients fail to complete the cycle, virtual birds are introduced into their field of view to guide them back to the bee patterns, thereby enhancing engagement. Results: This study reports only on the technical feasibility of the system. No clinical, behavioral, or usability data were collected. On a test dataset comprising 537 indoor images from the ADE20K dataset (accessed June 2024), the segmentation achieved a mean Intersection over Union (IoU) of 76.70% (SD = 8.2%) and an accuracy of 88.51% (SD = 4.7%). Conclusion: The NeuroNavAR program represents a preclinical engineering feasibility study that provides a more intuitive and user-friendly training experience compared to traditional rehabilitation methods. Its innovative use of augmented reality and real-time feedback is designed to support, but has not yet demonstrated, improved rehabilitation outcomes for patients with unilateral spatial neglect. Clinical validation is planned for 2026.
