OT Sensory Integration Model

STUDY
PLAY
Dyspraxia
Impairment in the ability to conceive, plan, sequence, or execute action
Postural Disorder
disorder causing difficulty stabilizing while moving
Postural reactions
Changes in body position to maintain equilibrium
Praxis
Planning motor action
Sensory Discrimination Disorder
Difficulty interpreting sensory information
Sensory Integration
Neuralogical process of organizing sensation from the body and environment that allows effect use of the body in the environment
Sensory Modulation Disorder
Disorder involving difficulty responding appropriately to the degree, nature, or intensity of sensory information
Sensory Modulation disorder: Sensory Overresponsivity
-Responding with more speed, intensity, or duration than is normal for a given sensory input
Sensory Modulation disorder: Sensory Seeking/ Craving
Having an extreme desire for excessive amounts of sensory stimulation
Sensory Modulation disorder: Sensory Underresponsitivity
blunted or slow response to sensory information
Sensory-Based Motor Disorder
Disorder that is seen as difficulties with postural or voluntary movement
Sensory Integration Assumptions
-Brain has neural plasticity
-Sensory integration skills follow a developmental pattern
-The brain functions as an integrated hierarchical unit
-People have an innate drive to seek sensory motor activities
-Brain organization and adaptive behavior are adaptive
Three factors for a playful approach to intervention (SI)
-Perception of inner control
-Intrinsic motivation
-Freedom from the constraints of reality
Elements of Sensory Integration Intervention
-Provide sensory opportunities
-Provide just-right challenge
-Collaborate on activity choices
-Guide self-organization
-Create play context
-Arrange room to engage the child
Desired results of sensory integration
-concentration
-organization
-self-esteem
-academic learning ability
-capacity for abstract reasoning
-specialization of sides of the brain (lateralization)
Sensory Systems (proximal or body senses)
-Vestibular: inner ear perception of movement/speed, relation to gravity
-Tactile: epidermis and dermis, meisner's/pacinian corpuscles, touch receptors
-Proprioceptive: Muscles, tendons, and joints that provide information about body position in space, postural control
Sensory Systems (Distal)
ENVIRONMENTAL
-vision
-auditory: spacial orientation, language development

CHEMICAL
-gustatory (taste)
-olfactory (smell)
Sensory Stimuli (CNS basic response)
-Supression (inhibition)
-Divergence: ability of brain to relay sensory input to multiple parts of the brain. This can result in necessary actions (facilitation).
-Convergence: synthesizing input from many sources so the brain can create an organized response.
Sensory Diet
-providing a succession of rich an varied sensory inputs on a daily basis
Dunn' Sensory Processing Model
-Sensory processing: brain makes meaning of sensory stimuli

4 basic patterns:
-Sensation seeking (high threshold, active)
-Sensation avoiding (low threshold, active)
-Sensory sensitivity (low threshold, passive)
-Low registration (high threshold, passive)
SI Assessments
-SIPT
-Sensory processing measures
-Interview
-Observation
