Sensory Presentation7 2009 3

  1. 1. Linda Gilles-Zirbes, OTR/L Occupational Therapist Palatine, IL The Sensory Systems, Processing and Strategies
  2. 2. The Sensory Systems <ul><li>Work together </li></ul><ul><li>Give us accurate picture of the world and our place in it </li></ul><ul><li>The brain uses sensory info in an organized way </li></ul>
  3. 3. Sensory Processing <ul><li>Is the receiving and perceiving of sensory info </li></ul><ul><li>Usually integration of sensory info is done without effort </li></ul><ul><li>Function of sensation is to aid in perception, the control of movement, and maintenance of arousal </li></ul>
  4. 4. Sensory Processing <ul><li>Components of Sensory Processing </li></ul><ul><li>1. Sensory modulation </li></ul><ul><li>2. Sensory discrimination </li></ul><ul><li>3. Praxis </li></ul>
  5. 5. Sensory Processing Processes <ul><li>1. Registration </li></ul><ul><li>2. Orientation </li></ul><ul><li>3. Interpretation </li></ul><ul><li>4. Organization of a response </li></ul><ul><li>5. Execution of a response </li></ul>
  6. 6. Sensory Processing Problems <ul><li>Possible causes and theories : </li></ul><ul><ul><li>Do not adequately receive or process information from these sensory systems as different wiring </li></ul></ul><ul><ul><li>Genetics: quirkiness within the family tree </li></ul></ul><ul><ul><li>Prematurity: immature/ disorganized nervous system </li></ul></ul><ul><ul><li>Birth trauma, medical procedures, medically fragile all put one more at risk </li></ul></ul><ul><ul><li>Deprivation </li></ul></ul><ul><ul><li>Problems coexisting with other conditions </li></ul></ul>
  7. 7. The Sensory Systems 1. Tactile System <ul><li>Largest and first system to develop </li></ul><ul><li>Tactile receptors throughout the body </li></ul><ul><li>This is the primary map of ME (homunculus) </li></ul><ul><li>Touch is important as an embryo and after birth </li></ul><ul><li>Touch gives us info and puts the boundaries in ME </li></ul>

  29. 29. Arousal levels and sensory <ul><li>Modulation: brain regulation and activity level via the balance between external and internal sensory stimuli </li></ul><ul><li>the way we modulate input affects our arousal state </li></ul><ul><li>our arousal levels change throughout the day, we try to keep an optimal arousal level using various strategies </li></ul>
  30. 30. Arousal Levels and Sensory cont. <ul><li>Types of arousal levels: </li></ul><ul><ul><li>low </li></ul></ul><ul><ul><li>optimal/ just right </li></ul></ul><ul><ul><li>high: often respond to sensory stimuli with a strong response, frequently in fright/ flight/ fight response, may remove self to get away/ may scream in fright with too much input </li></ul></ul><ul><li>those that spend more time in high and low arousal maybe constantly seeking or avoiding input to regulate </li></ul>
  31. 31. Sensory Behaviors and Sensory Strategies <ul><li>Behaviors we note with students often are proprioceptive: to get ME in the picture?
