Sensory Integration Flashcards
SI in OT refers to 3 things:
- the theory
- evaluation methods
- a specific approach to intervention
why do OTs get a bad wrap when it comes to SI?
the term is used so loosely within and outside of the profession
When working with sensory interventions, DON’T say ….. DO say …..
“I’m DOING sensory integration” / “I’m treating sensory processing disorder”
when working with SI, we work from a ……. perspective, NOT …….
occupation-based perspective / single theory or model
Steps in SI theory (kind of long but there’s an example):
sensory intake (ex: from clothes) > sensory integration (I’m uncomfortable) > planning and organizing behavior (I’m going to sit differently) > adaptive responses and learning > feedback (I’m more comfortable) > sensory intake…..
why does SI theory feed into emotional regulation?
you have to address the sensory aversion to avoid a negative emotional association
the ………. takes the information from the emotions in our …….. system and associates it to anything
amygdala / limbic
I don’t like Natalie > I can’t stand anyone who looks like Natalie
3 characteristics of SI theory
- explains why individuals behave in particular ways (unable to regulate sensory info)
- helps plan intervention to improve particular dysfunctions (monitor what you’re asking of the kid)
- predicts how behavior will change as a result of therapy (knowledge of the patterns and brain processes helps ability to predict)
5 assumptions from Ayres SI theory
- CNS is plastic
- SI develops over time
- brain functions as an integrated whole
- adaptive interactions are critical to SI
- there is an inner drive to develop SI through participation in sensorimotor activities
Ayres goal was to develop a theory to describe and predict relationships among:
neural functioning, sensorimotor development, and academic learning
Ayres definition of SI
the neurological process that organizes sensation from one’s own body and from the environment and makes it possible to use the body effectively within the environment
when Ayres defined SI, she was moving beyond the concept that….
body, mind, and learning are separate
2 outcomes of CNS dysfunction (chart)
- sensory modulation dysfunction
- dyspraxia (somatodyspraxia and BIS)
expressions of modulation dysfunction (4) - top to bottom
- aversive response
- gravitational insecurity
- defensiveness (tactile, auditory, visual…)
- under responsiveness
expressions of modulation dysfunction lead to (4) - top to bottom
- avoidance
- distractibility (inc activity)
- withdrawn
- sensory seeking
CNS site for modulation dysfunction
limbic/reticular
postural control is impacted by which senses
- visual
- vestibular
- proprioceptive
- tactile
discrimination is impacted by which sense
all (vis, vest, prop, tactile, aud)
2 expressions of dyspraxia
- BIS (feedforward-dependent)
- somatodyspraxia (feedforward & feedback-dependent)
expressions of dyspraxia lead to (4) - top to bottom
- clumsiness
- clowning
- avoidance of motor behavior
- exaggerated or diminished force
modulation dysfunction manifests from difficulties in the ……………. areas, while dyspraxia manifests from ……………. areas
- limbic/reticular
- posture/discrimination
T/F: there can be a mixture of avoidance & sensory seeking
true
gravitational insecurity looks like …………….. and interventions look like ……………
- avoiding anything off the ground (chairs, swings)
- start at the ground and make tiny increases until body can regulate it
- sloooooooow process b/c gravity is always “on”
adaptive responses
using sensation and experience to organize a successful goal directed action in the environment
adaptive responses are based upon which type of sensory information
ANY
benefit of adaptive responses
allows a child to successfully meet a challenge in the environment
child’s role in adaptive responses
ACTIVE DOER - you can’t put a kid’s hand in goo and call it SI b/c you’re taking their worst fear and putting it in a box with them
6 levels of adaptive responses
- tolerating passive stimuli during activity
- holding on and staying put
- alternate contraction and relaxation of muscle groups
- move independently in a familiar way
- move independently in an unfamiliar way
- complete a complicated activity requiring unfamiliar way, difficult timing, or multiple adaptations
importance of “staying put” adaptive response
let them know they’re safe and wait out fight or flight response
importance of alternating contraction/relaxation of muscle groups in adaptive response
increase self-efficacy & muscle memory
why should kids move in familiar then unfamiliar ways within adaptive responses?
-have familiar experiences to build on
then
-increase level of tolerance and give them control of the environment
when do you know adaptive responses are truly integrated and generalized?
the final stage is taking place: completing difficult activity in unfamiliar way, difficult timing, or with adaptataions
neural plasticity
structure and function of nervous system changes in response to ongoing stimulation
examples of neural plasticity
- meaningful and active engagement of child on environment may produce permanent changes
- adults with stroke
- adults who have part of their brain removed can have full cognitive recovery
ways to promote neural plasticity
- promote meaningful and purposeful activities
- make them want to engage so they’re in charge of the environment
feedback
- response from env that changes interaction (pushing a pull door)
- outcome feedback following action
- production feedback (through muscles & body in space)
- how we learn new behaviors
feedforward
- anticipatory control
- sending signals ahead of mvmt as we prepare for the mvmt
incorporating feedback & feedforward into intervention
work through and process feedback then talk about how to change it in the future (feedforward)
where do adaptive responses occur & why? how do you take advantage of this?
limbic system b/c emotions are tied into the response - tie in emotion to enhance the level of trust
what promotes adaptive responses?
interactions with the environment
inner drive
children have the innate desire to interact with their environment
when does the first recognizable response to sensory stim occur?
5 1/2 weeks gestation
the most important sense for the newborn
-touch
-smell
-movement
(this is why kangaroo care is so important)
importance of tactile input for newborns
establishes trust relationship w/ caregiver
newborn feeding is a reflection of…..
essential sensory integration skills
vestibular input and newborns
very calming
relationship of sensory input to the birthing process
it’s usually how decisions are made (water birth, kangaroo care right after)
with sensory system maturation in childhood….
the child becomes more independent with exploring the environment > more precise movements > increased sophistication with manipulating objects
