Towards the Threshold: A Fall-Risk Anchored Pareto Framework for Virtual Reality Gait Feedback Selection for Individuals with Multiple Sclerosis

It is demonstrated that greater gait improvement does not necessarily correspond to greater rehabilitation efficiency and a threshold-anchored efficiency framework is introduced to provide a quantitative framework for comparing VR feedback strategies according to both performance gains and participant burden.

Toward Postural State Classification in Immersive VR with Multimodal Data and Explainability Analysis

Comparing machine learning and deep learning models for classifying postural states in VR under visual perturbations suggests that multimodal sensing, temporal deep learning, and explainable AI can support reliable classification of balance-related instability in VR.
