Design and evaluation of a multimodal balance training system

Area of Science:

• Biomechanics
• Rehabilitation Engineering
• Physical Therapy

Background:

• Current balance training systems are specialized, leading to high costs and space inefficiency.
• Monotonous training programs limit patient engagement and rehabilitation progress.

Purpose of the Study:

• To design a single, multimodal balance training and assessment system.
• To accommodate static, dynamic, reactive, and proactive balance needs for diverse patient populations.

Main Methods:

• Integrated radial and circumferential driving mechanisms with a clutch system.
• Developed a compound foot plate with adjustable stiffness and interchangeable springs.
• Utilized kinematic equations to analyze system parameter effects on the center of gravity.

Main Results:

• Successfully combined multiple balance training modalities into one system.
• The foot plate offers multi-axis movement (X, Y, Z) and adjustable height.
• Real-time control of inclination angle, rotation, and speed is achieved.

Conclusions:

• The developed system is suitable for patients at various rehabilitation stages.
• Multiple functionalities enhance usability, reduce costs, and save space.
• Offers a versatile solution for comprehensive balance training and assessment.
