Posture-Vision Relationship Apparent Light Perception
Posture-Vision Relationship Rationale • Interrelationship between postural system and visual system is so powerful that deficit in one significantly influences the other. • Vision may be present but cannot be expressed until postural and motor system is prepared
Assessment Sequence • Organize postural alignment and symmetry • Facilitate quiet alert state • Influence movement and postural components that support visual function
We Won’t Impact Vision Until We Get Postural System in PlaceEvery Time We Make a Postural Adjustment We Must Allow For a Visual Adjustment
Minimally Responsive Child Posture & Movement Components of Visual Function • Postural tone • Head/neck Components • Shoulder Girdle Components • Upper Extremity Components • Trunk Components • Movement Skills
Apparent Light Perception Rationale • If light perception is apparent, it may represent minimal level of visual functioning • Any amount of light may be made more efficient for functional application • Student may be made aware of visual capacity and attend to motion, color, and distant lighting sources to better orient to and discriminate his surroundings and, subsequently, increase his independence
