What to asses?
Safety
- What is the main safety concern in this feeding?
- How will you screen for it in the community or school?
- What will you do if you suspect a problem?
Parts of the swallowing process
- Oral Phase
- Oral Propulsive Phase
- Pharyngeal phase
- Esophageal Phase
Aspiration
The drawing of a foreign substance into the respiratory tract during inhalation
Swallowing
- Develops early = in fetus (12-14 weeks gestation)
- ->Baby near 40 weeks swallows 1/2 of amniotic fluid per day
- At rest, mouth and throat structures favour respiration
- Valves
- ->lips, soft palate and tongue, epiglottis, UES
- Phases of swallowing: oral phase, pharyngeal phase, esophageal phase
Respiration
- Pharynx serves dual role
- ->air goes through to the lungs
- food goes through to the stomach
- The body must have airway protection mechanisms
Airway related to head position
–>babies with respiratory compromise may have extended head position to maximize airway stability
Label the mouth
right side
- Tongue
- Epiglottis

- Nasopharynx
- Oropharynx
- Laryngopharynx
- Esophagus
Clinical Indicators of Aspiration
Medical/feeding history and clinical evaluation
- history of aspiration pneumonia
- Coughing with oral feeds
- History of recurrent chest infections
- History of increased upper airways sounds/congestion during or after oral feeding
- History of wheezing and chest sounds with oral feeds
- Finding of chest x-ray suggestive of aspiration
- Sudden drop in heart rate with oral feeds
- Change in voice quality with oral feeds (wet voice)
Observing swallowing
- forces that impact pressure gradients
- Bolus propulsion
- Initiation of swallowing reflex
Swallowing Dysfunction
-Airway protection during swallowing
- Swallowing phases
- ->Aspiration before swallow
- ->Aspiration during the swallow
- ->Aspiration after the swallow
Videofluoroscopy
-A videofluoroscopic swallowing study (VFSS) usesa. form of real-time x-ray called fluoroscopy to evaluate a patient’s ability to swallow safely and effectively. It is typically well tolerated, noninvasive, and can help identify the consistencies of food that a patient can most safely eat
- AKA Modified Barium Swallow
- Cervical Auscultation
- Decision tree for videofluoroscopic feeding study
Gastroesophageal Reflux (GER)
- GER: spontaneous return of gastric contents into esophagus
- Aspiration from below
- Impact on feeding:
- ->volume
- ->frequency
- ->Gag reflex
- ->aversion
- Management:
- ->Important to work closely with MD and RD
- ->Medication
- ->Positioning
- ->Dietary
Nutrition and Growth
- How can nutrition or growth be a particular challenge for kids with disabilities?
- How will you screen for it in the community or school?
- What will you do if you suspect a problem?
Oral Motor Ability
- what is their current level of ability telling you about:
- What consistencies of food and drink that they can manage easily?
- What consistencies of food and drink they could achieve with some carefully graded experience?
Normal Development-oral Motor
Newborn
- Strong rooting reflex
- Strong gag reflex
- Reflective suck
Normal Development-oral Motor
One month
- Rooting and gag reflexes persist
- Suck-swallow-breath pattern may be poorly coordinated
Normal Development-oral Motor
Two months
-Begins mouthing hands
Normal Development-oral Motor
Three months
- Rooting beginning to disappear
- Start to see more non-reflexive up-down tongue movements
- Longer sequence of sucking before swallow/breathe
Normal Development-oral Motor
Four months
- Rooting reflex should be integrated
- Increased oral exploration of objects/toys
- Mature sucking pattern begins
- More active lip closure (less drooling and liquid loss)
Normal Development-oral Motor
Five Months
- Refinement of mature sucking pattern (cupped tongue, activation of lip/cheek muscles)
- Well coordinated pattern of suck-swallow-breathe (SSB)
- “Suckles” from spoon (tongue pushing forward)
Normal Development-oral Motor
Six months
- Mature sucking pattern and coordinated SSB
- Open mouth in anticipation of spoon
Normal Development-oral Motor
Seven Months
-Starts to clear food from spoon with active upper lip
Normal Development-oral Motor
Eight months
Actively clears food from spoon
-On a dry solid (e.g. cookie) will see suck, suckle or phasic bite-release
Normal Development-oral Motor
Nine to 10 months
Can transfer food from centre to side of mouth
- Munches on solids
- Holds dry solid between gums to break off a piece
Normal Development-oral Motor
Eleven to twelve months
- Begins to chew
- Able to suck liquid from a cup with well-coordinated SSB
Oral Motor Dysfunction
Problems:
- Organization of burst-pause rhythm (often called “coordination of SSB”)
- Strength of suck
- Structural problems
- ->cleft lip and palate
- Abnormal motor patterns
Sensory functioning
- Textures
- Colours
- Smells
- Appearance
Sensory Differences
Clinical Presentation
- Sensory defensiveness
- Not mouthing toys and fingers
- Gagging
- Stuffing
- Strong tasting foods
- Preference for self-feeding
Behavioural/Psychological Difficulties
-Is the problem specific to feeding?
When are the other times that the child and feeder interact and the child has control?
-What does the child need out of their eating time and other psychological interactions that they are not getting
Occupational level
- Self-Feeding
- Positioning
- Food Preferences and Range
- Speed and Self Regulation of Eating
Normal Development of Self-feeding Skills
- Depends on environment factors including: exposure/learning opportunities, family culture
