An interactive soft robotic hand-task training system with wireless task boards and daily objects on post-stroke...

Area of Science:

• Rehabilitation Engineering
• Robotics in Medicine
• Neurorehabilitation

Background:

• Stroke survivors often experience significant upper limb motor deficits.
• Task-oriented training is crucial for restoring hand function after stroke.
• Existing rehabilitation systems may lack adaptability and seamless interaction with daily objects.

Purpose of the Study:

• To develop and evaluate an interactive soft wearable robot hand system for stroke rehabilitation.
• To assess the system's effectiveness in improving upper limb function, hand-motor abilities, and grip strength.
• To investigate the long-term effects of the task-oriented training.

Main Methods:

• Development of a soft wearable robot hand with individually controlled finger actuators and a ring-reinforced soft actuator (RSA).
• Integration of a wireless task board for object interaction and task-specific training.
• Evaluation of the system with seven stroke subjects over 20 training sessions.

Main Results:

• Significant improvements were observed in Fugl-Meyer Assessment (FMA), Action Research Arm Test (ARAT), and Box and Blocks Test (BBT) scores.
• Maximum grip strength increased significantly post-training.
• Functional improvements persisted for at least 3 months after the training period.

Conclusions:

• The developed interactive soft robotic hand system effectively enhances stroke rehabilitation.
• The system promotes significant hand-motor recovery and functional gains in stroke survivors.
• Its lightweight, user-friendly design facilitates integration into routine therapy, supporting frequent hand practice.
