Generalizability of multimodal FOG detection beyond laboratory settings

Determine whether multimodal freezing-of-gait detection approaches generalize beyond standardized laboratory settings to real-world conditions.

Background

The paper reviews prior multimodal approaches to freezing-of-gait detection that combine sensing modalities to improve robustness. Although these methods have produced promising results, the paper notes that their validity outside controlled laboratory protocols has not been established. This unresolved issue is directly relevant to the paper’s focus on home-based activities of daily living, where environmental conditions, tasks, and movement patterns are substantially more variable.
