In PRI Vision, we spend our clinical days helping patients gain the ability to center themselves in space. We define centering as the neurological ability to use appropriate visual perception, capitalize on ascending support, and balance on each side. To center correctly, you must be able to be “neutral” as defined by PRI while performing this task. However, a person can be “neutral” and still not be able to center. Even though we are using visual input through the eyes to help patients accomplish this, centering must start with the floor.
