Executive Impact: Unlocking Adaptive & Reliable Rehabilitation
The integration of real-time fatigue estimation with an adaptive Bayesian fusion mechanism provides a critical advantage for rehabilitation robotics, ensuring consistent and reliable intention detection even during prolonged, fatiguing sessions.
Enhanced Robustness in Rehabilitation
By adaptively fusing EMG and EEG signals based on real-time fatigue levels, the system maintains high classification accuracy where unimodal systems would degrade, preventing misclassification and improving patient safety and therapeutic effectiveness.
Real-Time Adaptive Control
The continuous fatigue score dynamically adjusts the influence of peripheral (EMG) and central (EEG) biosignals, allowing for personalized control that responds to the user's physiological state without manual recalibration.
Scalable & Clinically Relevant
Designed for a portable rehabilitation robot, this system offers a practical solution for clinical stroke rehabilitation and motor recovery, demonstrating feasibility with low latency and user comfort.

Insights into the significance and implications of adaptive neuro-control for future rehabilitation strategies.
Impact of Adaptive Bayesian Fusion on Rehabilitation Robotics
The proposed adaptive Bayesian fusion model dynamically adjusts the weighting of EMG and EEG inputs based on real-time fatigue levels. This preserves classification accuracy even as EMG signal quality degrades due to muscle fatigue, a crucial capability for real-world rehabilitation scenarios. This dynamic adaptation ensures consistent and reliable intention detection, significantly improving the robustness and therapeutic effectiveness of upper-limb rehabilitation robots during prolonged sessions. Unlike static fusion methods, it provides a personalized control strategy that accounts for the user's varying physiological state.
Key Impacts:
- Maintains high accuracy even during prolonged, fatiguing sessions.
- Provides personalized control adapting to user's physiological state.
- Reduces risk of overexertion and improves user comfort.
- Enhances real-time motor intention decoding reliability.
