Tetrax FB is an innovative and highly effective diagnostic system:

Helps detect subtle neuro-physiological and neuro – disturbances in the Central Nervous, Spinal, Visual, Vestibular and Proprioceptive Systems

Provides specific information based on the dynamics of the neuro-physiological and musculoskeletal functions that are involved in the complex control of human balance

Can be used as an early pre-diagnostic tool thanks to its high sensitivity

Helps identify the key source area of disturbances and guides Health Care Professionals correctly in the process of differential diagnosis.


Tetrax FB works within the principles of Dynamical System Theory and the Theory of Simplicity, which state that a human body’s balance in space is based on the cooperation and interaction of a multiplicity and complexity of many subsystems which are under the control of efficient neurophysiological mechanisms.

This system assesses pressure fluctuations produced by the heels and toes of a subject standing on four separate platforms two for each foot and their respective halves.

The pressure plates emit electronic signals which are digitalized and processed by the Tetrax FB software to yield a set of unique parameters. Some parameters are equivalent to those that can be obtained through traditional posturography methods, while others are specific to Tetrax FB.

Calculated results based on these parameters, which are statistically and functionally independent, reflect the interactions of the various neuro-physiological and neuro-anatomic subsystems involved in balance control.

One of the only systems that are portable. second, one of the only systems that measure lateral sway and antero postirior sway it is important for differing between peripheral and central balance disturbances.

third, a certain frequency is sensitive to M.S.
