[Tracking axis of the body tracking test(BTT)].

Area of Science:

• Neuroscience
• Biomechanics
• Human Physiology

Context:

• Dynamic body balancing is crucial for daily activities and preventing falls.
• Quantitative assessment of balance function is needed for clinical evaluation and research.
• The body tracking test (BTT) offers a method to objectively measure dynamic balance control.

Purpose:

• To investigate the quantitative evaluation of dynamic body balancing function using the body tracking test (BTT).
• To analyze the movement of the body's center during tracking in healthy subjects across various age groups.
• To explore the relationship between age, spatial sensory abilities, and body movement patterns during balance tasks.

Summary:

• This study utilized the body tracking test (BTT) with 779 healthy participants to quantitatively assess dynamic balance.
• Analysis revealed consistent directional tilts in body center movement: clockwise for anteroposterior (A-P) and counter-clockwise for lateral tracking.
• Age influenced tracking patterns, with younger individuals (10-30 years) showing less tilt in lateral BTT, suggesting practice and spatial processing are key.
• Principal axis analysis identified deviations related to dominant foot, pivot foot, and right parietal lobe spatial sensing functions.

Impact:

• Provides normative data for dynamic balance assessment in healthy individuals.
• Highlights the role of age and neurological factors (parietal lobe function) in balance control.
• Suggests BTT can be a valuable tool for diagnosing balance disorders and monitoring rehabilitation progress.
