Sensory integration dysfunction, it is currently known, sensory processing disorder. It is a complicated, somewhat controversial disorder of sensory processing, the ability to take in, filter, and respond appropriately to sensory input. Some children are felt to be sensory avoiding, or sensory defensive, feeling bombarded by overly intense experiences of the touch, lights, sound, and so on. http://www.disorderscentral.com/sensory-processing-disorder.html

HSV 6350 Summer I 2009Module 6 Part 1Sensory Processing : 

HSV 6350 Summer I 2009Module 6 Part 1Sensory Processing Ben Atchison, PhD, OTR, FAOTA Western Michigan University

Sensory Processing : 

Sensory Processing Part I: Definitions and Concepts

Sensory Processing is.. : 

A term that refers to the way the central nervous system takes in sensory information and responds Sensory Processing is..

Normal Sensory Processing : 

Normal Sensory Processing All the senses work individually and with each other to allow smooth and effective responses to stimuli V A O T G P MVT

However… : 

However… Like a finely tuned engine, sensory processing can sputter… …..and perhaps breakdown.

Slide 6: 

Resulting in..A Sensory Processing Disorder V A O T G M

Sensory Processing Disorder (SPD) : 

Sensory Processing Disorder (SPD) SPD IS now recognized in the Diagnostic Manual of Infancy and Early Childhood and in Diagnostic Classification 0-3 Hoping to see inclusion in DSM-IV.

Applicable Conditions : 

Applicable Conditions Children with a history of abuse and neglect Autism Spectrum Disorders Fragile X Syndrome Learning Disabilities Fetal Alcohol Syndrome and FASD

Applicable Conditions : 

Applicable Conditions ADD/ADH Mental Health Impairment..especially severe and profound

Slide 10: 

Patterns of Sensory Processing Disorder (SPD) Sensory Modulation Disorder Sensory-Based Motor Disorder Sensory Discrimination Disorder SOR SUR SS SOR=Sensory Over-reactivity-Low threshold SUR=Sensory Under-reactivity-High Threshold SS=Sensory Seeking/Craving-High Threshold 2004, SU Workgroup-Miller, Lane, Anzalone, Osten Dsypraxia Postural Disorders Visual Auditory Tactile Vestibular Taste Smell

Slide 11: 

SENSORY MODULATION…. The capacity to regulate and organize the degree, intensity, and nature of responses to sensory input in a graded and adaptive manner. McIntosh, Miller, Shyu, & Hagerman, 1999

Slide 12: 

SOR SUR

Slide 13: 

Sensory Events Over Time Low Arousal Optimal Level of Arousal Sensory Overload Sensory overload, shut down Sensory Defensive Regulated, Non Defensive Underresponsive Wilbarger, 1991 High Arousal

Sensory Modulation DisordersSensory Over-Responsivity : 

Sensory Modulation DisordersSensory Over-Responsivity

Slide 15: 

SOR Behaviors include Oversensitivity to: Textures Glue, mud, etc. on hands Feeling crumbs on mouth Playing on swings and other anti-gravity things Bright lights Changes in posture such as somersaults Irritable, fussy Excessively cautious Is upset by transitions and unexpected changes Unsociable; difficulty forming relationships Source: Miller, L (2006) Sensational Kids

Slide 16: 

Sensory Over-Responsivity

Sensory Modulation DisordersSensory Under-Responsivity : 

Sensory Modulation DisordersSensory Under-Responsivity

Slide 18: 

SUR Behaviors include: High pain tolerance; doesn’t cry when hurt Doesn’t notice when being touched Doesn’t like trying new activities Seems unaware of things around him Has to watch hands when using them Doesn’t notice noxious smells Source: Miller, L (2006) Sensational Kids

Slide 19: 

SUR Behaviors: Prefers sedentary vs active, physical play Easily lost in fantasy world Passive, quiet withdrawn Apathetic

Slide 20: 

Is something we all engage in… Sensory Modulation DisordersSensory Seeking

Slide 21: 

However, sensory seeking can result in disorganized behavior or random behavior that is limited in its purpose…

Slide 22: 

Sensory-Seeking Behaviors Include: Loves to crash, bump, jump Loves “roughhousing” Constantly touching, poking Frequently stares at objects, reflections Has difficulty sitting still Hard to calm “Fidgety”

Slide 23: 

Sensory-Seeking Behaviors Include Constant motion Takes excessive risks Likes to lick, chew, suck non edibles Likes TV, music at high volume

Slide 24: 

SENSORY BASED MOTOR …. Includes postural integration, which allows for movement foundation and praxis, which is the ability to plan and perform a novel motor action or series of motor actions. Miller and Lane, 2000

Slide 25: 

Behaviors indicating Sensory Based Motor Disorders: Difficulty learning new motor skills Often trips, bumps into things Slow developmental to sit, crawl, walk, run Difficulty with following directions Problems keeping things organized Messy eater

Slide 26: 

Behaviors indicating Sensory Based Motor Disorders Difficulty with sequential tasks such as getting dressed Difficulty with handwriting Frequently breaks toys

Slide 27: 

SENSORY DISCRIMINATION…. The ability to discern the qualities, similarities, and differences among sensory stimuli, including differentiation of the temporal or spatial qualities of sensory input. Miller and Lane, 2000

Slide 28: 

Visual Discrimination

Slide 29: 

Auditory Discrimination

Slide 30: 

Tactile Discrimination

Slide 31: 

Vestibular Discrimination

Slide 32: 

Oral Sensory Discrimination

Slide 33: 

Olfactory Discrimination

Sensory Modulation DisordersSensory Discrimination : 

Sensory Modulation DisordersSensory Discrimination Behaviors Indicating Disorders Difficulty knowing what is being held without seeing it Judging force such as amount of pressure to hold pencil Awareness of differences in sounds, smells, visual symbols Gets lost easily Sorting out background stimuli and attending to the essential stimulus at hand “bog” for dog “caf” for cat Vase or Faces?
