This study introduces a new mathematical method to separately analyze the two key processes involved in maintaining body equilibrium. This approach clarifies how posture shifts and center of mass stabilization are affected in locomotor disorders.

Area of Science:

Biomechanics
Human Physiology
Neurology

Background:

Body equilibrium relies on two main processes: reference point shifts due to posture changes and stabilization of center of mass oscillations.
The precise alterations in these equilibrium processes during various locomotor disorders are not well understood.

Purpose of the Study:

To develop and present an original mathematical method for independently assessing the two primary components of body equilibrium maintenance.
To provide a tool for better understanding the biomechanics of balance in individuals with movement impairments.

Main Methods:

Development of a novel mathematical framework.
Separate quantitative evaluation of postural reference point shifts.
Independent assessment of center of mass stabilization during oscillations.

Main Results:

The proposed method successfully distinguishes and quantifies the two distinct processes contributing to body equilibrium.
This allows for a more granular analysis of balance control mechanisms.

Conclusions:

The new mathematical method offers a valuable approach to studying body equilibrium.
It can help elucidate the specific deficits in balance control associated with different locomotor disorders.
