Posturographic
devices

Overview

Posturography is a non-invasive specialized clinical assessment technique used to quantify how well a person is able to control posture and balance.

Depending on the conditions in which the subject's balance is tested, it is common practice to classify posturography techniques in one of two major categories: static and dynamic posturography.

The role of the postural control system is to control the movement of the Center of Mass (CoM) of the body and to minimize its undesired motions. In other words, its role is to maintain the control of the Central Nervous System (CNS) over the CoM. The movement of the CoM is what is called sway, and posturography works by measuring sway.

In 2013, the International Society for Posture and Gait Research (ISPGR) estabished standards for clinical CoP measurements: accuracy of 0.1 mm, and precision and resolution of 0.05 mm*. Since its introduction to the market in 2002, well before the ISPGR standards were developed, our CAPS® systems have satisfied these requirements, because we recognized from the beginning the importance of determining the CoP with sufficient accuracy and precision.

Not all posturography devices are created equal! This has extremely important consequences to the clinical use of posturography. If the instruments used are not accurate and precise enough, it is impossible to detect small changes that could be clinically significant.

The CAPS® Professional

The CAPS® Professional is our top of the line computerized posturography equipment, thanks to its very high static load limit (up to 1 ton) and its manufacturing process (using aeronautical grade composite material).
