Sensory Integration and Processing Flashcards
(26 cards)
Definition of Sensory System
-7 or 8 areas (if you include interoception)
-work in continuous feedback loop within nanoseconds
-organizing sensory input for functional behaviors
Deficits in sensory system
-perception (sensory)
-organization (CNS)
-coordinated response (motor response)
Motor skills do not develop independently of _________
sensory experiences and perception
True or false. Sensory perceptions do not have connections with the limbic and autonomic nervous system
False.
sensory perceptions can cause poor emotion regulation, stress, anxiety, and low self-esteem
Sensory-based interventions
addressing an individual’s sensory deficits
Sensory integration framework
a method of assessing someone’s sensory system/integration
How does sensory integration and processing as a system differ from the medical model?
The medical model tends to focus on deficits, a system or wellness model focuses on the whole person and is applicable to all populations and ages
What is the progression of the sensory system driving motor behavior?
Sensory -> Motor -> Social -> Behavior
Theory of Sensory Integration
-Jean Ayres
-Explains relationship b/w deficits in interpreting sensation of the body and the environment, and difficulties in academics or motor learning
Branches of sensory processing disorder (SPD)
-Sensory Modulation Disorder (SMD)
-Sensory-based Motor Disorder (SBMD)
-Sensory Discrimination Disorder (SDD)
Sensory Discrimination Disorder
-Struggles with understanding and responding to differentiated sensory stimuli across difference sensory systems
-Also deficits with processing multiple sensory information at once
Deficits in proprioception
-poor body awareness
-difficulty with posture (leaning)
-clumsiness
-using too much or too little pressure
-“sensory seeking behaviors” (crashing, roughness, etc. trying to get more info to regulate)
Deficits in vestibular system
-low muscle tone
-poor balance
-improper reactions to movements/uncoordination
-toe walking
-lack of trunk rotation or visual scanning
How is toe walking related to the vestibular system?
Increasing the extensor tone helps to activate the vestibular system
Deficits in tactile system
-difficulty with fine motor skills (handwriting)
-avoiding certain textures of food, clothing, or surfaces
-hypersensitive to unexpected touch
Deficits in visual system
-sensitivity to light
-avoiding visual attention
-hesitation to go on stairs or playground equipment
-difficulties with math ability and spatial orientation
-struggles with hand-eye coordination
Deficits in auditory system
-negative response to unexpected or loud noises
-difficulty focusing with background noise
-auditory inattentiveness
-overstimulation / unable to habituate
True or false. The auditory, taste, and smell system have connections with the limbic system
True.
The taste and smell systems are connected to the limbic system via the amygdala and hippocampus
Deficits in taste and smell systems
-feeding difficulties
-avoiding certain places or people b/c of their perception or associations with smell
Interoception
Restrictive: Only sensations stemming from viscera
Inclusive: experience of the body state as a result of the CNS. Pain, hunger, heartbeat, temperature, etc.
Sensory modulation disorder
-Difficulty with the sensory system staying in harmony
-Is on a spectrum
-Can be over or under responsive (defensiveness vs. dormancy)
-can result in sensory seeking or avoidant behaviors
Sensory based motor disorders
deficits in stabilizing and performing or planning movements because of sensory issues
Dyspraxia
-Praxis = motor planning!
-issues with creating and executing muscle movements, but only in the neural activity.
-can have typical neuromuscular function but still have dyspraxia b/c it applies to motor planning specifically
Postural disorder
-poor core strength and endurance
-moving inefficiently b/c of poor balance and body awareness
-no internal motivation
-poor bilateral coordination
-poor occular-motor ability
-gravitational insecurity
