Q

How does the ICF conceptualise functioning and disability?

A

As a dynamic interaction between a person’s health condition and their contextual factors. (Contextual factors = the complete background of an individual’s life and living). (WHO, 2001).

Q

Why is it important for SLPs to focus on contextual factors?

A

*holistic approach *ensuring that communication skills are generalisable to client’s real-life communication contexts. *Communication is collaborative -> needs a communication partner (environmental factor) *SLP can address environmental factors that influence a with speech & language difficulties’s participation. *consistent terminology within SP and across disciplines and countries. *ICF is a good social policy tool that can be used to advocate for greater community access for clients. *easier to identify specific barriers and facilitators that need to be considered. *attention to personal factors helps SLPs deliver more person-centred, personalise therapy

Q

What is expected of new graduates re: dysphagia?

A
  • Standard (not complex) client management (w/ adequate supervision)

Q

Supervision is V. important in the area of dysphagia for new grads because…

A

If you do something contraindicated, you can actually cause damage and there can be serious outcomes if mismanaged. Know your limitations.

Q

Why do we eat?

A
  • Pleasure

* Nutrition/hydration

31
Q

Dysphagia - example mapped onto ICF…

A

Health condition - Dysphagia
Body function and structure - delayed initiation
Activities - changes in oral intake
Participation - distress because unable to join in socially

32
Q

Potential consequences of dysphagia:

A
  • Aspiration
  • Risk of developing aspiration pneumonia or chest infection
  • Malnutrition and dehydration
  • Decreased funtioning of pulmonary system
  • inability to take oral medication
  • Increased length of stay and costs
  • Poorer outcomes, nursing home admission
  • Psychosocial implications and quality of life
  • Poor oral health (from decreased saliva production) with later risk of oral bacteria spreading around body
33
Q

Dysphagia and Nutrition

A

Malnutrition and dehydration are serious consequences

  • Poorly nourished - perform @ lower level, have overall worse outcomes than well nourished patients
  • Work with dietician - get nutrition assessment
  • Dysphagia may not be primary cause of malnutrition (ie, cancer…)
34
Q

Consequences of poor nutrition:

A
  • General fatigue
  • Depression
  • Muscle degradation
  • decreased day to day functioning
35
Q

Consequences of poor hydration (bear in mind esp. if client on modified fluids):

A
  • Poor skin turgor
  • Darkened urine
  • Dry mucous membranes
36
Q

Psychosocial impact of dysphagia:

A
  • Depression, fear, trust, loss of control and embarrassment (refs in presentation).
  • Eating less enjoyable, more anxiety provoking.
37
Q

Aspiration:

Silent aspiration:

A
  • entry of food/fluid into airway, below level of vocal folds.
  • Silent -> as above but with no obvious clinical signs like cough or wet voice.
38
Q

Laryngeal penetration:

A

When substance enters airway but doesn’t go below the level of the vocal folds.

39
Q

Can you determine aspiration from a bedside clinical assessment alone?

A

NO! Need a videofluroscopy.

40
Q

A potential indicator of a history of aspiration:

A

A history of chest infections.

41
Q

Aspiration pneumonia:

A

*chest infection caused by aspiration of foreign matter, bacteria or gastric juices into lower respiratory tract (BUT not always caused by dysphagia [although a contributing factor]. AND not everyone who aspirates will get it. People who are not mobile are at higher risk).

42
Q

Study (Langmore et al, 1998) showed other risk factors often present in people with oropharyngeal dysphagia who developed aspiration pneumonia. Other risk factors were:

A
  • Dependency for oral feeding
  • Dependent for oral care
  • Number of decayed teeth.
  • Tube feeding
  • Multiple medical diagnosis
  • Number of medications
  • Smoking
43
Q

Why is using the ICF framework so important in dysphagia management?

A

Dysphagia has a huge impact on how a person lives their life. (Psychosocial impact/QoL reduction, activity/participation limitations).

44
Q

Which of the stages of swallowing is voluntary, therefore requires cognitive input to complete successfully?

A

Oral stage.

45
Q

Why does the pharyngeal stage of the swallow require cognitive input to function optimally?

A

Because it’s initiated by specific oral manipulations of food by the tongue, and since this (oral) stage is vountary and requires cognition, this will also affect the involuntary pharyngeal phase.

46
Q

2 primary instrumental evaluations for dysphagia:

A
  1. Fibreoptic endoscopic evaluation of Swallowing (FEES)

2. Videofluoroscopic modified barium swallow evaluation

47
Q

Why might basing therapy and recommendations for dysphagia management just on the results from FEES or Videofluoroscopy have limited relevance or practicality for a given patient?

A

Tests done in clinical conditions without their normal foods and environments. Can’t tell what they typically eat (ie dried meats) or how they chew or swallow this particular food, while drinking alcohol and talking with friends, for example….

48
Q

Dysphagia assessment and subsequent intervention must achieve the four goals of (Threats, 2007, p.332):

A

1) adequate nutrition and hydration
2) decreased risk of aspiration related illnesses
3) decreased choking risk
4) decreased risk of psychosocial effects (ie social isolation, depression…)

49
Q

List four levels of neural control for swallowing:

A
  • Cortex
  • Cerebellum
  • Brainstem
  • Peripheral
  • impairment at any of these levels can result in swallowing impairment
50
Q

Afferent

A

coming in

51
Q

efferent

A

going out

52
Q

Two important nuclei in brainstem, referred to the ‘swallowing centre’:

A
  • Nucleus tractus solitaris (NTS)

* Nucleus ambiguous (NA)

53
Q

Nucleolus tractus solitarius (NTS)

A
  • Sensory (afferent) info from CN V, VII and X (touch, temp. and taste)
  • Located dorsal medulla
  • surrounded by reticular formation
  • Imp. for cardio, respiratory and tone regulation -> coordinates this info
54
Q

Nucleus ambiguous (NA)

A
  • Located in ventral medulla
  • surrounded by reticular formation
  • Afferent info from CN V, VII, IX and X from NTS sent on to NA, and NA coordinates motor output to CN V, VII, IX, X and XII.
55
Q

Which CN involved in swallowing only has a motor, not a sensory, function?

A

CN XII

56
Q

Cortical input to the swallow

A
  • Nec. for voluntary swallow - novel bolus, or being asked to swallow something on cue.
  • role in volitional control (oral phase) and influences timing of pharyngeal phase
57
Q

Brain parts involved in cortical input to voluntary swallow:

A
  • input is bilateral and multifocal:
  • Anterior insular cortex
  • Primary and supplementary motor cortices
  • Sensoricortex
  • Anterior cingulate gyrus
  • Cerebellum
  • Thalamus
  • Amygdala
  • Internal capsule
  • How much, and under what circumstances, each area has an input is still unknown
58
Q

Why is it important to assess both reflexive and voluntary swallow?

A

They have different brain inputs.

59
Q

‘Hunger centre’

A

Hypothalamus

60
Q

Which area of the brain regulates thirst and hunger?

A

Hypothalamus
(*Also recieves input from NTS - damage to NTS can also affect how much intake people who may present with dysphagia actually feel)

61
Q

What might be impacted if areas governing taste and smell are damaged?

A
  • eliciting responses to food (salivation etc)

* desire to eat / how appetising food is.
