Our sensory system consists of ____ areas which work in a ____ feedback loops to regulate and make sense of sensory information in order to funtion.
- seven
- continuous
Ayres described sensory integration as
the brain’s ability to organize sensory input for use in functional behaviors
What is the sensory system loop
response, sensory input, processing
Deficits in the sensory system
perception, organization, coordinated response
Why is sensory processing important to PT
part of every aspect of human function
human development
affects movement to acheive optimal outcomes
Motor skills do not develop independently of
sensory experiences and perception
Sensory perceptions have connections with ____ and ____ causing poor ________.
emotion
autonomic nervous system
emotional regulation, stress, anxiety, poor self-esteem
Levels of Sensory drives Motor
sensory –> motor –> social –> behavior
Why did Jean Ayres originate the theory of sensory integration
to explain the relationship between deficits in intepreting sensation from the body and the environment and difficulties with academic or motor learning
Sensory Processing Disorders
Sensory Modulation
Sensory-Based Motor
Sensory Discrimination
Sensory Modulation Disorder
Sensory Over-Responsivity
Sensory Under-Responsivity
Sensory Seeking/Craving
Sensory-Based Motor Disorder
Dyspraxia
Postural Disorders
Sensory Discrimination DIsorder
Visual, Auditory, Tactile, Taste/Smell, Position/Movement
Information provided by joints and muscles to keep people oriented in space
Proprioception
Movement processing that tells you whether the body is moving and in what direction
Vestibular
What plays a role in generating general muscle tone?
Vestibulat Spinal Tract
Ability to discriminate touch through the skin
Tactile
Ability to conform to objects pressure
Tactile: Dorsal column medial leminiscal tract
Poor tactile discrimination can lead to
difficulty with fine motor skills (handwriting)
Avoid: textures with food, clothing, surfaces
Hypersensitive to unexpected touch
What is included in the visual system
hand-eye coordination, visual spatial orientation, visual-motor skills
development of visual imagery and mental manipulation
Visual difficulties can result in
sunlight sensitivity, avoid visual attention, hesistate to go on stairs or playground
Difficulties in the auditory system can result in
negative response to unexpected/loud noises, difficulty focusing with background noise, auditory inattentiveness, overstimulation
Limbic system is connected to
auditory system and taste/smell system
hypersensitivity to tastes and smells can lead to
feeding difficulties
