A Wearable Personalised Sonification and Biofeedback Device to Enhance Movement Awareness

Area of Science:

• Biomechanics
• Rehabilitation Engineering
• Wearable Technology

Background:

• Movement sonification shows promise for rehabilitation and motion control.
• Existing systems for gait detection and sonification face challenges in cost-effectiveness, usability, and reliability.
• Enhanced movement awareness is crucial for individuals with irregular gait and posture.

Purpose of the Study:

• To introduce a novel wearable personalized sonification and biofeedback device.
• To improve movement awareness for individuals with irregular gait and posture.
• To facilitate gait correction and enhance functional mobility through real-time auditory cues.

Main Methods:

• Integration of inertial measurement units (IMUs) and MATLAB for data processing.
• Development of a wearable sensor system for capturing kinematic parameters.
• Generation of real-time auditory feedback (discrete and continuous tones) based on heel strike and sagittal plane rotations.

Main Results:

• Preliminary testing with 20 participants demonstrated promising improvements in movement awareness via auditory cues.
• The system showed potential for enhancing gait and balance.
• The device offers real-time feedback for posture and movement adjustments.

Conclusions:

• The developed wearable sonification and biofeedback device shows potential for gait rehabilitation.
• Auditory cues can significantly improve movement awareness, benefiting individuals with compromised gait.
• Future research should focus on real-world applications and diverse populations, including the elderly and Parkinson's patients.
