Evaluation of statokinesigram using 3-D plotting and discriminant function

Area of Science:

• Biomechanics
• Human Posture and Balance
• Neuroscience

Background:

• Maintaining erect posture involves complex righting reflexes.
• Understanding these reflexes is crucial for assessing human balance and stability.
• Current analysis methods for postural sway have limitations.

Purpose of the Study:

• To introduce a novel 3-D plot of the statokinesigram for analyzing human righting reflexes.
• To improve the understanding of postural stability through enhanced visualization and parameterization.
• To develop new discriminant parameters for analyzing postural sway patterns.

Main Methods:

• Utilized a 3-D plot of the statokinesigram, X-Y histograms, and discriminant function analysis.
• Analyzed ninety samples from 30 healthy individuals using an on-line digital processing system.
• Developed parameters based on the distribution map of the center of gravity's sway.

Main Results:

• The 3-D plot provides an intuitive map of righting reflex patterns.
• New parameters derived from the 3-D plot show high discriminant ratios.
• These parameters are comparable to those obtained from traditional locus and area analyses.

Conclusions:

• The 3-D statokinesigram plot offers a valuable tool for intuitive analysis of righting reflexes.
• The developed parameters effectively discriminate postural sway patterns.
• This approach enhances the understanding of human postural control mechanisms.
