Leveraging Sensor Technology to Characterize the Postural Control Spectrum.

Area of Science:

• Biomechanics
• Human Movement Science
• Wearable Technology

Background:

• Postural control is crucial for daily activities and injury prevention.
• Current methods for assessing postural control are often confined to laboratory settings.
• There is a need for unobtrusive, real-world assessment tools.

Purpose of the Study:

• To develop and validate novel instrumentation and analysis techniques for characterizing the postural control spectrum.
• To focus on emerging wearable sensors for applications outside traditional clinical or laboratory environments.
• To assess postural stability, postural agility, and dynamic stability.

Main Methods:

• Investigated optimal placement and number of wearable accelerometers for postural stability assessment.
• Developed metrics and protocols for postural agility using a force plate-controlled video game.
• Proposed frequency-domain metrics from IMU data for dynamic stability during walking.

Main Results:

• Wearable sensors and proposed metrics demonstrated effectiveness in differentiating unstable conditions from stable ones.
• The developed methods show potential for reliable and unobtrusive postural control assessment.
• Initial findings support the feasibility of real-world postural control monitoring.

Conclusions:

• Emerging wearable sensors and advanced analysis techniques offer a promising avenue for accessible postural control assessment.
• The developed protocols and metrics can differentiate between stable and unstable postural states.
• Future work will focus on larger populations and refining methods for diverse scenarios.
