Gait Measurement at Home Using A Single RGB Camera

Area of Science:

• Biomedical Engineering
• Computer Vision
• Health Informatics

Background:

• Gait analysis is crucial for assessing overall health, correlating with disease incidence, mortality, and fall risk.
• Gait is infrequently evaluated in clinical settings, potentially delaying health issue detection.

Purpose of the Study:

• To develop an accessible, home-based gait measurement system.
• To enable continuous gait monitoring outside of clinical environments.

Main Methods:

• A novel system utilizing a single RGB camera for gait analysis.
• Requires minimal setup: placing a camera and marking four floor points.
• Measures step positions and timings, enabling calculation of various gait parameters.
• No wearable devices are needed for the individual being assessed.

Main Results:

• The system's accuracy was validated against a motion capture system.
• Demonstrated a clinically insignificant error of 3.62 cm/s in walking speed measurement from the side view.

Conclusions:

• The proposed system offers a feasible and accurate solution for home-based gait analysis.
• Facilitates non-invasive, regular health monitoring through gait assessment.
