postural sway
The Past
Dr. Fred Illi (famous early chiropractor from Switzerland) developed the first four-quadrant weight scale in the mid-twentieth century. The idea was to determine the location of the center of gravity of a patient in quiet standing. The thought being the further from the center, the more physical stress the body would be under.
A reliability assessment of four-quadrant weight-scale measurements
In the mid 1980’s, I developed a four-quadrant weight scale using computerized scales. We could not only measure the center of pressure (what we used to think was center of gravity), but could also measure the postural sway over a short time period. Two papers were written using this device.

The Present
In 2018 we built a new model, THE CENTRE OF PRESSURE SCALE.
Measuring postural sway in the standing position is the focus of much research right now.

It should be seen that this device is good for both assessment and outcomes measurements for conditions such as concussions and risk of falling.
The Future
As data is collected and stored, machine learning will determine various common patterns of center of pressure procession. As the clinician collects samples, he sends them to a prescribed data bank. These new patterns may be indicators for many conditions outside of post-concussion symptoms and falling risks.
