Q
Topic Feeding:
Define the following:
-feeding
-eating
-swallowing
A
  • Feeding – self feeding- process of setting up, arranging and bringing food from talbe, plate or cup to mouth
  • Eating – ability to keep and manipulate food or fluid in mouth and swallow it
  • Swallowing – complex act in which food, fluid, medication or saliva is moved from mouth through the pharynx and esophagus into stomach

Q

Anatomy and Development of Oral Structure

A

Structures:

  • Oral cavity
  • Pharynx – funnels food to esophagus; allows food and air to share space
  • Larynx – valve to trachea to close during swallow
  • Trachea – allows air to flow into lungs
  • Esophagus – carries food from pharynx to stomach

Newborn:
Oral cavity filled with fat pads inside tongue and cheeks to aid in grasping and compressing nipple

6 month old:
-oral cavity larger and tongue up and down movement now extract the liquid

  • Sucking patterns become more voluntary
  • Oral motor skills support the in take of lumpy textures and chewing

Q

Important role in proper timing of breathing and swallowing during oral feeding (infancy/as child grows)

A

Infancy:
-Structures in close proximity in infancy – epiglottis and soft palate are in direct approximation so fluid safely moves from nipple to base of tongue to esophagus

-Very little aspiration first four months - they can feed in reclined position

As child grows:
-Space is created between hyoid, epiglottis and larynx and base of tongue – child needs greater coordination for suck swallow and breath

-Greater risk for aspiration in reclined position so child begins to eat upright

Q

What are the 4 phases of swallowing?

A

Phases of Swallowing:

  1. Oral preparatory phase
    - Reflexive in young infants; voluntary control for others
    - Oral manipulation of food
    - Form bolus
  2. Oral phase
    - Reflexive in young infants; voluntary control for others
    - Tongue elevates against alveolar ridge of hard palate moving bolus posteriorly and ends with onset of pharyngeal swallow
  3. Pharyngeal phase
    - Primarily reflexive
    - Swallow is triggered; movement of hyoid and larynx; epiglottis protects airway opening; upper esophageal sphinter opens
  4. Esophageal phase
    - Reflexive
    - Starts with relaxation of upper esophageal sphinter and ends to relaxation of lower esophageal sphinter to allow food to move into stomach

Q

What are the Stages and Ages of Feeding Development?

A
  • In utero
    Suck swallow develops 10-14 weeks gestation
    16-20 months gestation mouths thumb

-New born
Premature infant may not be ready for oral feeds – then tube feedings
Healthy newborn has reflexes and physiological flexion that help with eating
Sensory and social experiences help them bond with the parent through touch, sounds, eye contact and smells

-3-6 months
More head and neck control so feeding becomes more upright
Brings hands to bottle
Brings toys to mouth – helps get ready for eating new textures in the future
Some start accepting pureed now

-6 months
Definitely ready for pureed via spoon
Learns to open mouth in response to spoon and clear puree from spoon
Still breast or bottle feeds

-8-12 months
Finger foods
Vertical chew develops at first then tongue lateralization
Cup drinking introduced with spillage

-12-24 months
Brings loaded spoon to mouth at 12 months
Masters scooping by 18-24 months
Wean from bottle/breast
Rotary chew – diagonal jaw movements and tongue lateralization
Soft and coarsely chopped table foods
By 24 months tougher foods mastered

-24 months to 5 years old
By 3 years old accepting a variety of table foods
By 5 years old feeding patterns are fully functional adult patters

Q

What does a Comprehensive Evaluation of Feeding and Swallowing Skills includes?

A
1. Initial interview and Chart review:
Health status
Record review
Developmental history
Interview caregivers
How is feeding going? What are your concerns?
How much does the child eat and drink?
Mealtime routine? How often does the child eat? Where does he/she eat?
  1. Observation of muscle tone, nueromuscluar status, sensory processing and developmental level
    Low tone – decreased postural control
    High tone – difficulty grading or sustaining oral motor patterns, poor coordination, drooling, decreased oral exploration, limited self feeding
    Sensory processing difficulty – decrease attention, difficulty managing certain textures, poor tolerance to mealtime experiences
  2. Structured Observation
  3. View the structures of the mouth – jaw lips tongue gums teeth palates
  4. Observe child eating
    Have parent feed child to note the process and interactions
    Use foods child prefers as well as some more challenging foods
    Note signs of aspiration – food or liquid entering the airway beforem during or after swallow
    Gagging
    Coughing
    Choling
    Nasopharyngeal reflux
    Increased congestion
    Wet vocal quality
    Frequent respiratory infections and/or pneumonia

Q

Intervention Strategies for feeding?

A

Environmental Adaptations (may need trial and error to determine effectiveness)

  • Meal time routines and schedules
    Allows for time without food/juice/milk to increase hunger
    Consistent location for eating

-Length of meal time
No longer than 30-40 minutes (15-30 minutes is best)
Children with reflux may benefit from smaller shorter meals more often

-Sensory stimulation during meal time
Decrease distractions

-Sequence of food offerings

-Positioning adaptations  (always promote socialization)
Providing external support can assist with self feeding as well as oral motor control
Infants 
Side lying for bottle/breast may be best – gravity does not immediately draw fluid to pharynx
Car seat can support infant 
Supine drinking of bottles is not generally recommended
Toddlers
High chair with towel rolls
Tumble form feeder seat
Older children
Wheelchair may be best
Optimal positioning
Vertical head and trunk position
Greater than 90 degrees hip flexion
Knee flexion 90 degrees
Feet supported flat

Q

What are some adaptive equipment for feeding?

A

Adaptive equipment:

  1. Spoons
    Shallow bowl helps with decrease lip closure
    Bumpy spoon helps with decreased sensory awareness
    Rubber coated spoon helps with bite reflex
    Curved handles and large grips aid with self feeding
  2. Straw
    Short straw and/or small straw – results in smaller bolus for managing
    One-way valve straw – helps with weak suck
    Long straw – decrease hand use
    Cup
  3. Nosy cup – helps keep head in neutral

Q

Modifications to Liquids

A

-Thin liquid from an open cup is most difficult to manage

-Thickened liquid is easier to control with lips and tongue:
Easier to manage bolus for effectively swallow without spillage into pharnageal cavity
Helps to avoid aspiration
Helps when first learning cup drinking even without aspiration noted
Xanthan gum thickeners can cause serious intestinal issues (necrotizing enterocolitis)
Natural thickeners such as blending fruits for smoothies may be better choice

Typical suggestions by Ots:
Thickened liquid
Carbonated liquids
Chin tuck position for delayed swallow initiation but not when there is softening of cartilage of trachea or larynx
Shorter meal time to avoid fatigue
Multiple swallows to clear food – can offer empty spoon to elicit another swallow if needed
Adapting pace of meal
Difficulty foods first before fatigue

Q

What does Cleft Lip and Palate looks like?

What are treatments like before surgery?

What are treatments like after surgery?

A
-Hole in the structures that usually join together at midline in the first weeks of fetal development
Require surgery to repair
Effect on feeding
Difficutly latching
Ineffective milk transfer
Prolonged feeding times
Milk leaking from nose
Poor weight gain
Can effectively breast or bottle feed if this is their only issue with a few adaptations

-Treatment before surgery
More upright posture in sitting
External support at cheek/lip
Adaptive nipples for bottle
One way valve – delivers milk with little or not suction
Longer nipple – deposits milk towards back for mouht

-Treatment after surgery
Scar massage
Sensitivity treatment
Small amounts of liquid or food at each bite/sip
Alternating food and drink

Important components of sucking
``` Easily initiated Rhythmical Strong Sustained efficient ```
26
``` Biting: Under 5 months 5-6 months 9 months 12 months 24 months ```
Under 5 months – not appropriate 5-6 months – no controlled bite 9 months – holds cookie between gums without biting through; feeder breaks off 12 months – controlled, sustained bite 24 months – able to grad jaw opening when biting foods of various thickness
27
Chewing + Tongue Movement : ``` Under 5 months 6 months 9 months 15 months 24 months ```
Under 5 months – only sucking 6 months – munching – up and down jaw movement 9 months – some rotary jaw movement 15 months – diagonal rotary – jaw moves down and laterally or down and diagonally as food moves from mid tongue to side or side to mid tongue 24 months – circular rotary – circular or semi-circular jaw patterns with food moving across mid line to opposite sides – used for tougher/firmer foods
28
``` Lips under 6 months 6 months 9 months 12 months 18 months 24 months 3 to 4 years old ```
Under 6 months – sucking 6 months – does not use teeth or gums to clean food from lips 9 months – draws lips in when food on them 12 months – still may lose food when chewing; actively cleans lips 18 months – can chew with lips closed; loses some 24 months – no longer loses food 3 to 4 years – keeps lips closed for appropriate table manners
29
Define Jaw Instability
Insufficient tone allows jaw to slip and shift forward
30
Define Tonic Bite Reflex
Jaw tightly clenches when teeth are stimulated, may be difficult to release Caused by – abnormal muscle tone
31
Define Tongue Protrusion
Movement seen in normal suck pattern, but protrusion is slightly exaggerated (sticks out beyond lips) Caused by – abnormal tone - lack of tongue mobility
32
Define Tongue Thrust
Forceful protrusion of tongue; thrusting makes feeding very difficult Caused by – abnormal tone - lack of tongue mobility
33
Define Lip Retraction
Tendency for lips and cheeks to be pulled into tight, retracted position Caused by – high tone
34
Describe Low Tone in Cheeks
Reduction in strength and skill in cheeks causing spillage, drool, poor articulation and mouth breathing Caused by – low tone - cranial nerve damage
35
Define Hyper reaction
Stronger reaction to specific sensations Caused by – neurological issues - tube feeding
36
Define Hypo reaction
Milder reactions to a specific sensation than would be expected Caused by – neurological issues
37
Drooling is caused by..
Caused by – abnormal tone - teething - inefficient swallow - constant wet face
38
Feeding Treatment– emotional component
Do not upset child – may take along time to regain trust May need same person to always feed Establish routines and rituals OT try strategy first then train feeders then OT moves off when possible
39
Feeding Treatment – Medical Issues
Do not elicit gag reflex then it will diminish When in doubt – get swallow study!!! To decrease tube feeds – work with dietician – child must be hungry to eat successfully by mouth Bite reflex – don’t pull away – relax child/neck flexion Always wash hands/wear gloves
40
Feeding Treatment – Sensory Issues
Taste/smell – bland food may not be meaningful; add taste if child over stuffs mouth Proprioception – use taste/temperature if child does not know tongue Vestibular – use this sensation to mediate arousal level for feeding and for increased postural control
41
Feeding Treatment – Poor Head Control
Start with handling/sensory input to normalize tone Proper positioning – 909090 - hands at ML - maintaining position should not be work - car seat or w/c may work best
42
Feeding – Jaw Instability
Start with handling/positioning External jaw control technique Biting games – “bite and tug” Snack cap
43
Feeding Treatment – Tongue Thrust/Protusion
``` Start with handling/positioning Work on Jaw Control Cup drinking Increase lumpiness of food textures to encourage chew Work on quiet mouth as food approaches Place food at molar Stimulate sides of tongue ```
44
Feeding Treatment – Limited Lip Movement
``` Start with handling/position Massage – ears to mouth - nose to mouth Straw drinking Downward pressure on tongue with spoon elicits lip closure ```
45
Feeding Treatment – Hyper reaction
``` Start with handling/positioning Calm environment Work on decreasing gag reflex Work on hand to mouth Work on toys to mouth Let child know food is coming Grade food textures Brushing/wash cloth/cosmetic sponges/nuk brush Electric toothbrush Deep pressure to teeth ```
46
Feeding Treatment– Hypo reactive
Start with handling and positioning Variety of stimulations – tastes and textures Cue for over stuffing
47
Feeding Treatment -Drooling
``` Start with handling and positioning Increase sensory awareness around mouth Work on Jaw and lip control Work on independently wiping mouth Work on Straw drink – Transport – moving liquid from front of mouth to back ```
48
Form of Play: | Activities in which children engage
Play is an end in and of itself Play is spontaneous, voluntary, rewarding and pleasurable Play differs from other behaviors in form or timing – i.e. only in infancy or very exaggerated Play is repeated but flexible Play is not stressful
49
At what age does the following begin? Sensorimotor play Exploratory play Constructive play Symbolic play Social play Games with rules
Sensorimotor play 0-2 years old Exploratory play First year of life; actively explores environment; interested in how things work Shows up again when child is learning new things Constructive play Building and creating; i.e. sandbox, blocks, arts and crafts Symbolic play 2-5 years old; peeks at dramatic play; encourages self-regulation, empathy and civility During middle childhood it evolves into fantasy play such as daydreaming, secret clubs, riddles, mental games Social play By 3 years old, child can engage in complex social games such as role playing using different identities; i.e. parents, characters, etc. Games with rules Teaches turn taking and to initiate, maintain and end social interactions
50
What does Adolescents’ time consist of?
- Socializing - Television - Sports/hobbies/games Screen time – virtual interaction Sharism – fast-paced sharing of ideas (i.e. Minecraft) Shifting identities – boundaries between mine and yours blurring with video exchanges Border crossing – moving between virtual and physical world more (i.e.. Sky landers_ Literacies beyond print – reading and writing with e-readers and apps Gaming culture – forgiving and responsive world is expected because they can access “undo” button Bricoleur culture – eager to hack, modify, program and recycle
51
What are the functions of play?
``` Many purposes of play Develop life skills Expend extra energy Relaxation Achieve optimal arousal Develop ego Develop cognition Develop social abilities Contribute to culture Role development ```
52
Meaning of Play
Play meaning – quality of the play experience, person’s state of mind and value of play experience for the individual
53
Define Playfulness | What are the dimensions/elements of play?
– attitude during play ``` Dimensions of play: Physical spontaneity Cognitive spontaneity Social spontaneity Manifest joy Sense of humor ``` Elements of play Intrinsic motivation Internal control Ability to suspend reality
54
Context of Play
Play obtains meaning through context ``` Factors influencing play Environment/physical setting Family Culture Toys ``` More variety of materials then better quality play Quality of care Less parent supervision then more creativity More responsive the care giver then better quality play Socioeconomic status I.e. higher socioeconomic then more dramatic play
55
Factors promoting play
``` Familiar toys, peers, materials Freedom of choice Nonintrusive adults Safety Schedule that avoids fatigue, hunger or stress novelty ```
56
Factors inhibiting play
External constraints Limited choices Too much novelty or challenge Over competition
57
Play Assessment
Play is considered child’s major occupation ``` Developmental Competencies: Four areas -Space management -Material management -Pretense/symbolic – separate reality from make-believe -Participation ``` Play, Playfulness and Play Style: Analyze state of mind during play Look at environment during play Use child self-report and perceived self-competencies Interpreting Play: Assessments Standardized assessment tools may inhibit play Best to observe child in natural environment multiple times across multiple settings
58

64
Constraints to Play: CP
Variety of difficulties impacting play Motor Cognitive Decreased social opportunities
65
Play in Interventions
In therapy, if OT drives the activity it may no longer be viewed as play by the child – it becomes work Two primary ways to use play in OT : Intervention modalities to improve specific skills As an intervention goal
66
Play in Interventions: Playfulness in Occupational Therapy
Playfulness helps with generalization during difficulty situations OT should show playful attitude Novelty Imaginary play Mixed age play – develop leadership skills, creativity and imagination
67
Play in Interventions: Play Spaces and Adaptations
Novel objects added to play increases playfulness – increased creativity, activity and socializing Adapting toys Children should control placement of toys and objects AAC
68
Play in Interventions: Parent Education/Supporting parents
``` Parent Education: Barriers to play Limitations by adults Physical and personal limitations of child Environmental barriers Social barriers ``` ``` Supporting parents: Help design play spaces Toy inventories Allow children to do more Model play behavior ```
69
Play in Interventions: Societal Concerns
``` Decreased time for free play Overscheduled Decreased recess Safety concerns – less time outdoors Video game time increasing Obesity Exposure to violent games ```

Describe this Reflex: | Moro
- The Moro reflex is an infantile reflex - develops between 25–30 weeks of gestation and disappears between 3–6 months of age. - a response to a sudden loss of support and involves three distinct components: spreading out the arms (abduction) pulling the arms in (adduction) **look at visuals if you can it will help**
71
Describe this Reflex: | ATNR
The asymmetrical tonic neck reflex (ATNR) is a primitive reflex found in newborn humans that normally vanishes around 6-7 months of age. -It is also known as the "fencing reflex" because of the characteristic position of the infant's arms and head, which resembles that of a classically trained fencer. **look at visuals if you can it will help**
72
Describe this Reflex: | STNR
Symmetrical Tonic Neck Reflex (STNR) The Symmetrical Tonic Neck Reflex (STNR) provides the separation of body movements between the upper and lower half of the body. -It is developed after the ATNR and allows the infant to defy gravity on their hands and knees, and is a precursor to creeping. **look at visuals if you can it will help**
73
Describe this Reflex: | Palmer grasp reflex
- The palmar grasp reflex is elicited by placing an object or the examiner's finger in the palm of the infant's hand; - this leads to an involuntary flexion response. - This reflex subsides by 3 to 6 months of age - replaced by voluntary grasping, which is necessary to allow transfer of objects from hand to hand.
74
Describe this Reflex: | rooting reflex
- A reflex that is seen in normal newborn babies, who automatically turn the face toward the stimulus and make sucking (rooting) motions with the mouth when the cheek or lip is touched. - The rooting reflex helps to ensure successful breastfeeding.
75
Describe this Reflex: | sucking reflex
- It is paired with the rooting reflex, in which a newborn searches for a food source. - When he finds it, the sucking reflex allows him to suck and swallow the milk
