RehabMate System Architecture
RehabMate integrates a data collection layer (IMUs, video), a data fusion layer (multimodal graph construction), and a data analysis layer (action recognition, language model). This modular design ensures comprehensive data processing from input to personalized feedback, supporting a clear, traceable workflow for pediatric stroke rehabilitation.
It leverages multiple sensors for robust data capture and a sophisticated backend for processing and generating actionable insights, making AI support practical in home and community settings.
3s-AFPGCN for Action Recognition
The core of RehabMate's action detection is the 3s-AFPGCN (three-stream attention-based feature pyramid graph convolutional network). This model processes multimodal graphs from joint, bone, and dynamic angular features, using Adaptive Graph Convolutional Networks (AGCN) and Adaptive Dilation Temporal Convolutional Modules (ADTCM) to extract spatial-temporal representations. It is specifically designed to recognize lower-limb rehabilitation actions like walking, standing, and stair climbing/descending with high accuracy.
The innovative multi-stream approach and attention mechanisms allow it to capture complex motion patterns, crucial for distinguishing similar actions and adapting to individual variations in pediatric patients.
Personalized Feedback Generation
RehabMate incorporates an enhanced language model, integrating action recognition results with a professional rehabilitation corpus. This module generates real-time, personalized corrective feedback and motivational support. Feedback is tailored to the child's age, pain level, and mobility, ensuring safe and effective guidance.
The Retrieve-Copy-Generate Network, augmented with a curated corpus and Llama 3.1, ensures the feedback is clinically grounded, traceable, and adjustable by medical professionals, significantly improving the practicality and trustworthiness of AI in rehabilitation.
Interpretability & Robustness Validation
The system's interpretability is quantitatively validated through metrics like Critical Region Overlap (CRO), ensuring AI decisions align with expert judgments. Modality Saliency Score (MSS) verifies the contribution of IMU data for capturing acceleration anomalies.
Traceability Accuracy (TA) confirms that generated corrective suggestions can be accurately traced back to the knowledge base. This rigorous validation makes RehabMate a trustworthy tool for physiotherapists, enabling them to understand the rationale behind AI recommendations and make informed adjustments to training plans.

Case Study: Empowering Home-Based Pediatric Stroke Rehabilitation
Challenge: Pediatric stroke survivors often face long-term rehabilitation needs, but access to professional therapists and structured training is limited in home and community settings. Existing AI solutions typically act as "black boxes," offering results without clear explanations, hindering adoption by healthcare professionals.
RehabMate's Solution: Our framework provides an explainable AI system that combines precise action detection with personalized, corrective feedback. Physiotherapists can now understand *why* the AI suggests certain corrections, tracing decisions back to specific spatial-temporal features. This fosters trust and enables individualized training plans.
Impact: With 93.3% accuracy in action recognition and 94.6% feedback traceability, RehabMate empowers families with a reliable, intelligent tool for continuous rehabilitation. Children receive tailored guidance, improving outcomes and reducing the burden on healthcare systems.
