Interactive Gait Rehabilitation Through Gamified Real-Time Biofeedback and Adaptive Hip Exoskeleton Assistance: A...

Area of Science:

• Rehabilitation Engineering
• Biomechanics
• Human-Computer Interaction

Background:

• Gait rehabilitation requires engaging and personalized therapeutic tools.
• Current systems may lack real-time, integrated biofeedback for muscle activity.
• Exoskeleton technology offers potential for targeted physical assistance and resistance.

Purpose of the Study:

• To design and evaluate an interactive rehabilitation system integrating a hip exoskeleton with a game-based environment.
• To provide real-time biofeedback of muscle activation (electromyography) and motion tracking.
• To assess the system's functionality in a controlled gait rehabilitation scenario.

Main Methods:

• Developed an interactive system combining a hip exoskeleton with a game environment featuring an anatomical avatar.
• Implemented real-time full-body motion tracking and electromyography (EMG) biofeedback.
• Conducted a functional evaluation with a healthy subject using assistive and resistive hip control modes during treadmill walking.

Main Results:

• The system successfully visualized motion and EMG-based muscle activation on an avatar mirroring user movements.
• Assistive mode reduced muscle activation, while resistive mode increased it, demonstrating targeted training capabilities.
• Post-processing enabled detailed analysis of kinematics, torques, and EMG patterns.

Conclusions:

• The interactive system shows significant potential as a feedback-driven platform for gait rehabilitation.
• The system's adaptability and biofeedback features can be tailored for personalized rehabilitation programs.
• This technology offers a novel approach to enhance patient engagement and therapeutic outcomes in physical therapy.
