Development of wrist rehabilitation robot and interface system

Area of Science:

• Rehabilitation Engineering
• Neuroscience
• Biomedical Devices

Background:

• Hemiplegic patients often experience significant upper limb motor deficits.
• Traditional rehabilitation methods can be labor-intensive and may lack patient engagement.
• Objective and quantifiable measures are crucial for effective rehabilitation progress tracking.

Purpose of the Study:

• To develop and evaluate a practical wrist rehabilitation robot for hemiplegic patients.
• To enhance patient motivation and training effectiveness through advanced features.
• To provide an accessible and user-friendly rehabilitation tool.

Main Methods:

• Development of a compact wrist rehabilitation robot with mechanical rotation, sensors, and a computer system.
• Integration of myoelectric sensors to monitor muscle activity (extensor carpi radialis longus/brevis and flexor carpi radialis).
• Implementation of a mirror training function for autonomous, bimanual wrist rehabilitation and a user-friendly interface.

Main Results:

• The robot successfully facilitates both extension and flexion training in an 'excited' state triggered by myoelectric signals.
• The bimanual mirror training function enables autonomous and effective rehabilitation.
• Hospital trials verified the effectiveness and practicality of the developed robot system.

Conclusions:

• The developed wrist rehabilitation robot offers a practical and effective solution for hemiplegic patients.
• The system's features, including myoelectric control and mirror training, enhance rehabilitation outcomes.
• The robot's compact design and user-friendly interface contribute to increased patient motivation and adherence.
