The Eyes and Proprioception

Abstract

The proprioceptive system has an extensive influence on the maintenance of human health. When the proprioceptive system is dysfunctional, the central nervous system does not recognize the correct status of tonicity of the muscles at rest or in movement, does not integrate correctly the information that comes from sensory receptors, and has difficulty in modulating multisensorial integration, with consequences in motor behavior and cognitive functions. This results in a wide range of proprioceptive abnormalities which are clinically related, are treated together, and are termed as Postural Deficiency Syndrome (PDS) or more recently Proprioceptive Dysfunction Syndrome. The author has personally observed more than 40,000 patients suffering from this condition during the last 40 years and devised an active prism therapeutic protocol that is based on the knowledge that small modifications of the muscular tonus of the oculomotor muscles can change the tonus of the axial paravertebral muscles. This paper describes PDS diagnosis and provides explanation of the updated active prism protocol aimed toward vision professionals.
