Central-Peripheral Integration...What does it mean?

This pre-recorded webinar focuses on central-peripheral integration as related to anatomy and physiology of visual and vestibular systems.

Description

One of the most common questions we receive is in regard to central-peripheral integration. What we have come to realize is that this term appears to have various meanings, so let's take a look at central-peripheral integration from different angles:

1. Central-peripheral integration as related to functional anatomy and physiology by discussing eye movements: For instance, saccadic eye movements are the quick jumps we make to move our eyes from target to target. Saccades is controlled by 2 important systems that we discussed in the V2FIT certification program: (1) our central vision which is the “What is it?” (ventral stream) system that allows to fixate on a target to provide a clear image; and (2) our peripheral or side vision which is the “Where is it?” (dorsal stream) system that locates the next target to tell our eyes where to move. These 2 systems must work seamlessly together for us to read. Central-peripheral integration appears to be disrupted with head trauma, resulting in several symptoms and decreased performance in the following areas: visual attention, processing speed, reaction time, simultaneous processing, multi-tasking, organization, efficient reading skills, balance integration and good performance.

2. Central-peripheral integration as related to motion sensitivity: This term is also used to describe focusing on something centrally while processing information in your periphery – imagine riding in a car. You are looking forwards but your brain is receiving a lot of information from the periphery. Following head trauma, this often becomes difficult and leads to motion sensitivity while riding in a car, being in busy places, etc. Thus, there appears to be a reference to central-peripheral integration as more of a sensitivity to processing busy and/or incorrect visual stimulation.

3. Central-peripheral integration as a theoretical foundation for rehabilitation to promote neuroplasticity: Think of it this way…as therapists, we are taught that you start in the most supported position to optimize function then begin to increase the demand of the task by decreasing the support base. For instance, you may start a patient in sitting then progress to standing then eventually on more uneven and/or dynamic surfaces. More sensory (or periphery) information can also be done by adding proprioceptive input with weighted vests, grounding techniques, and/or resisted movements (e.g., proprioceptive neuromuscular facilitation techniques). In other words, we are increasing proprioceptive input (in the periphery…our bodies) for central compensation. Thus, central-peripheral integration from a therapy reference appears to be synonymous with sensory integration.

Objectives

Webinar attendees will learn about central-peripheral integration as related to functional anatomy and physiology of the visual and vestibular systems, to motion sensitivity and to a theoretical foundation for rehabilitation to promote neuroplasticity.
