[Multi-channel motion signal acquisition system and experimental results]

Area of Science:

• Biomechanics
• Exercise Physiology
• Biomedical Engineering

Background:

• Understanding muscle function during exercise requires integrated physiological and biomechanical data.
• Existing systems may lack the capacity for simultaneous multi-modal data acquisition.

Purpose of the Study:

• To develop and implement a multi-channel data acquisition system for comprehensive exercise analysis.
• To enable synchronous recording of electromyography, kinematics, plantar pressure, and ultrasound imaging.

Main Methods:

• Designed a multi-channel system for synchronized data collection.
• Integrated hardware components for acquiring surface EMG, joint angle, plantar pressure, and ultrasound data.
• Developed software for real-time data acquisition and storage.

Main Results:

• Achieved synchronous acquisition and storage of surface EMG signals.
• Successfully recorded joint angle and plantar pressure signals concurrently.
• Obtained synchronized ultrasonic images alongside other physiological data.
• Demonstrated initial successful data collection and system functionality.

Conclusions:

• The developed system provides a robust platform for studying muscle function during physical activity.
• Simultaneous multi-modal data acquisition offers novel insights into exercise biomechanics and physiology.
• This system facilitates advanced research in sports science and rehabilitation.
