An AI-driven multimodal smart home platform for continuous monitoring and intelligent assistance in post-stroke patients

Abstract

At-home rehabilitation for post-stroke patients presents significant challenges, as continuous, personalized care is often limited outside clinical settings. Additionally, the absence of comprehensive solutions addressing diverse monitoring and assistance needs in home environments complicates recovery efforts. Here, we present a multimodal smart home platform designed for continuous, at-home rehabilitation of post-stroke patients, integrating wearable sensing, ambient monitoring, and adaptive automation. A plantar pressure insole equipped with a machine learning pipeline classifies users into motor recovery stages with up to 94% accuracy, enabling quantitative tracking of walking patterns. A head-mounted eye-tracking module supports cognitive assessments and hands-free control of household devices, while ambient sensors ensure sub-second response times for interaction. These data streams are fused locally via a hierarchical Internet of Things (IoT) architecture, protecting privacy and minimizing latency. An embedded large language model (LLM) agent, Auto-Care, continuously interprets multimodal data to provide real-time interventions-issuing personalized reminders, adjusting environmental conditions, and notifying caregivers. Implemented in a post-stroke context, this integrated smart home platform increases overall user satisfaction by an average of 115% (p<0.01) compared to traditional home environment. Beyond stroke, the system offers a scalable framework for patient-centered, long-term care in broader neurorehabilitation and aging-in-place applications.
