Résumé
Acquired brain injury (ABI), constitutes a major medical challenge with incapacitating implications affecting motor and cognitive functions like attention. One common attention deficit is unilateral spatial neglect, which is characterized by the lack of acknowledgement of the contralateral side of a hemispheric lesion. Virtual reality (VR) stands out as an innovative approach complementing estab- lished neglect neurorehabilitation methods such as prism adaptation (PA). This study aims to identify game-specific predictors for success in VR-based rehabilitation and to understand how patient react to PA in VR. 17 ABI patients from the Lausanne University Hospital were included in this study. They were part of a rehabilitation study using MindFocus, a set of VR rehabilitation serious games, ad- dressing cognitive deficits, developed by MindMaze SA. This project focuses on a tennis game, which targets spatial attention by inducing a visual shift following the PA principle. Statistical analyses were performed on patients’ hand trajectories and accuracy to correlate them with clinical data, aiming to predict behavioral patterns. The results of the analysis showed that left neglect patients showed sig- nificantly poorer accuracy with difficulty in targeting balls with left-oriented trajectories, while right neglect patients showed more difficulty in hitting right-oriented balls. We identified factors associated with better scoring, notably lower age, or early start of training. All patients improved their accuracy and hand trajectories, and by this mean, a stronger acknowledgement of the neglected side and a correct adaptation to the virtual visual shift. This study validates the effectiveness of PA in VR in ad- dressing neglect and highlights its potential as a complementary therapeutic method. It emphasizes the importance of integrating emerging technologies into traditional programs for more effective and individualized rehabilitation planning.
