Q

Discuss the steps in dysphagia Assessment

A
  • Screening may be involved first to determine if Ax is necessary. Can be done by other healthcare professionals (CDA, nurse, nursing assistant, etc.). If concern is raised during screening, then move on to Assessment.
  • Assessment should involve both sensory and motor functions.

Ax option #1: Bedside swallow with cranial nerve examination (should involve CNs V, VII, IX, X XI and XII). Patient questionnaires should be also done.

Ax option #2: Instrumental assessment provides more objective information regarding how sensory function may be impacting swallowing.
- Modified Barium Swallow Study (MBSS)/ Videofluoroscopic Swallow Study (VFSS)
- Fiberoptic Endoscopic Evaluation of Swallowing (FEES):

Q

What is the largest need for instrumental examination for dysphagia?

A

To view function that cannot be viewed (or perceived well) clinically, and we need to assess function to determine if there are deficits. Most clinicians find anatomical changes by surprise. That is, they are not suspected at the bedside in most cases.

A major clinical indication for either VFSS and FEES, therefore, is silent aspiration. Another is to determine changes in timing, coordination, and weakness in the pharynx that leads to penetration, aspiration, and residue

Q

Advantages of VFSS and FEES

A

VFSS
Pros:
- Radiation exposure is considered minimal
- VFSS can be used to assess kinematics of swallowing
- Residue can be measured using special software

FEES
Pros:
- Can do bedside assessments as it is portable
- If equipment (ex. halo brace) is used by patient, FEES is beneficial as it would not obstruct view of study.
- Laryngeal function can be observed
- Has higher sensitivity to penetration and aspiration

Q

Describe the supraglottic and super supraglottic swallow. What are these techniques used for? What’s the difference between the two?

A

The goal of the techniques is to:
1.Combine components of a breath hold for vocal fold adduction
2. A cough to eject any material that enters the airway 3. A repeat swallow to clear any remaining residue.

Both techniques have been shown to be beneficial for a variety of populations as both a therapeutic technique to facilitate better airway protection motor patterns as well as to serve as a compensatory strategy for an impaired swallow.

Supraglottic:
1. Take a deep breath and hold it. 2. Take a bite or a sip into your mouth. 3. Swallow while stillholding your breath. 4. Cough immediately after the swallow. 5. Swallow again. 6. Exhale and relax.

Super supraglottic:
1. Take a deep breath and hold it. 2. Take a bite or a sip into your mouth. 3. Bear down with your arms on the surface beneath you or pull up against the bottom of the seat to create tension in your body. 4. Swallow while still holding your breath and bearing down. 5. Cough immediately after the swallow. 6. Swallow again. 7. Exhale and relax

Holding your breath results in vocal fold adduction to prevent material from passing below the vocal folds. For patients with poor airway closure, the Super Supraglottic swallow may help to better achieve that by the addition of the arytenoid head approximation to the epiglottis and adduction of the false/ventricular folds Volitional coughing or clearing your throat helps clear any residue in the larynx or entrance to the airway. Then, the second swallow helps to clear any remaining residue. Both techniques have been shown to increase tongue vs. hard palate pressures

Q

What should be present to recommend a supraglottic swallow?

A
  • Decreased laryngeal vestibule closure leading to penetration or aspiration (impairment)
  • Residue in the pyriform sinuses that spills into the larynx post-swallow (post-cricoid spillage) (impairment)
  • Poor superior movement of the arytenoid heads towards the epiglottis during laryngeal vestibule closure (impairment)
  • Effective volitional cough with ejecting penetrated or aspirated materials (strength)

Q

Describe the effortful swallow.

A

Steps:
- Close your mouth and lips (optional: and press your tongue against the roof of your mouth). Swallow as hard as you can, like you are trying to swallow a large pill to help you squeeze your tongue and throat muscles tighter.
- Squeeze really tightly. Repeat 5-10 times.

Patients may have xerostomia (dry mouth) during this. If safe, they can take breaks with water.

Research has indicated that completion of effortful swallows can improve: tongue to palate contact, increased base of tongue (BOT) retraction and contact with the posterior pharyngeal wall (PPW), hyolaryngeal elevation and excursion vocal fold closure, pharyngeal constriction, and opening of the upper esophageal sphincter (UES)

This leads to increased pressures to propel the bolus down through the pharynx and into the esophagus more efficiently

Q

Describe the steps of the mendelsohn maneuveur and what its purpose is.

A

Steps:
- Find your Adam’s apple with your finger.
- Swallow and feel it lift up as you swallow.
- Swallow again, but try to hold the swallow and hold your breath while keeping your Adam’s apple up during the swallow. Hold this for 2 seconds.
- Release and breathe.
- Repeat this 5-10 times for 3-5 total sets. Allow 1 minute between sets for rest.

Q

Describe the chin tuck against resistance (CTAR) and what its purpose is.

A

Tucking chin while swallowing. Some use a ball under the chin as means of resistance.

This exercise can strengthen the muscle group called the suprahyoids/submentals and improves hyolaryngeal elevation and excursion

Q

When targeting hyolaryngeal elevation, what are you looking to improve?

A

It can lead to overall improved airway protection, because the entrance to the laryngeal vestibule/upper airway is further out of the way of the bolus flow as it elevates during the swallow.

It can also lead to increased opening of the upper esophageal sphincter (UES) in extent and duration of the opening which can lead to overall reduction of residue in the pyriform sinuses.

Q

What would you see in an exam to recommend the chin tuck against resistance (CTAR)?

A

On an MBSS/VFSS, if you identify:
- Decreased anterior movement of the hyoid bone
- Post-swallow residue in the pyriform sinuses
- Esophageal retention (food getting stuck) in the upper esophageal segment or just below it.
On FEES, if you identify: - Residue in the pyriform sinuses

At bedside, patients may complain of food getting stuck or feeling residue at the bottom of their throat.

Q

Describe the tongue press exercise and what its purpose is.

A

The tongue press exercise incorporates strengthening components of isometric squeeze without removing the tongue from its natural environment during swallowing (the oral cavity) and without need for external planes on which to apply resistance, such as a tongue depressor.

Steps:
- Relax your mouth and jaw so that your teeth touch each other lightly.
- Anterior tongue-press : Find the bump or ridge just behind your teeth, in front of the roof of your mouth.
- Press against the ridge with your tongue firmly and hold it for 10 seconds. You will feel the muscles under your jaw tighten. Repeat this exercise 5-10 times.
- Posterior tongue-press: Find the edge of the hard palate, near where it meets the soft palate.
- Press against the palate with the back part or your tongue firmly and hold it for 10 seconds.
- You will feel the muscles under your jaw tighten. Repeat this exercise 5-10 times.

Q

What would you see in an exam to recommend the tongue press?

A

On an MBSS/VFSS:
- Lingual weakness include: Decreased bolus gathering due to poor lingual mobility during oral phase
- Decreased AP propulsion of the bolus into the pharynx
- Post-swallow residue along the tongue, hard palate, base of tongue and/or in the valleculae
- Decreased contact of the base of tongue and posterior pharyngeal wall due to poor base of tongue strength
- Piecemeal deglutition required due to poor lingual control and AP propulsion

On FEES:
- Lingual weakness: Residue in the vallecula post-swallow
- Prolonged oral phase and piecemeal deglutition
- Residue along the base of tongue

At bedside:
- patients may present with prolonged oral phase, complaints of difficulty getting the bolus back into their throat, and /or oral residue along the tongue and/or hard palate post-swallow

17
Q

Describe the Masako maneuver and its purpose.

A

Steps:
- Stick out your tongue between your teeth (or gum line for edentulous patients) and gently bite down. - Keep your tongue out in that position with your mouth open and swallow your saliva hard.
- Repeat this exercise 5-10 times.

This exercise can help immediate posterior pharyngeal wall (PPW) contraction increases, and possibly in gains of PPW strength over time. The Masako may inhibit back of tongue (BOT) and anterior pharyngeal movements useful for vallecular clearance and airway protection, and lead to increased UES relaxation pressures, which could be particularly problematic for patients who already have poor BOT movement and post-swallow residue.

18
Q

What would you see in an exam to recommend the Masako maneuver?

A

On MBSS/VFSS:
- Decreased base of tongue retraction
- Post-swallow residue in the vallecula
- Post-swallow residue along the posterior pharyngeal wall
- Visible space between the base of tongue and posterior pharyngeal wall during the pharyngeal phase ofthe swallow
- Decreased pharyngeal stripping wave

OnFEES:
- Post-swallow residue in the vallecula
- Post-swallow residue along the posterior pharyngeal wall
- Visibly decreased base of tongue movement

At bedside, patients may complain of food getting stuck in their throat (assuming pharyngeal sensation is intact), and you may see multiple swallows per bite of food due to perceived residue.

Q

When working with a dietitian, what would be considered your role as an SLP, their role as a dietitian and both of your roles?

A

SLP:
- Identifying signs+symptoms of dysphagia
- Assessing and treating dysphagia
- Incorporating dietary preferences + cultural practices during Ax and Tx of dysphagia

Dietitian:
- Identifying nutritional problems (including those affected by dysphagia)
- Creating diet plans to incorporate caloric and nutritional intake
- Incorporating dietary preferences + cultural practices to maintain or improve nutritional status

Both:
- Respecting QOL choices
- Engaging in interprofessional collaborations to address patient’s needs
- Working with facility and caregivers to ensure appropriate intake

21
Q

What is presbyphagia and around what age does it begin to occur?

A

Characteristic changes in the swallowing mechanisms of healthy older adults that result from the normal aging process. It begins at around 50 years old.

This does not mean that the swallow is automatically impaired. The swallow can remain functional along with these changes.

22
Q

What are some anatomical/phsyological changes to swallowing with aging?

A
  • Sarcopenia: Decline in muscle mass
  • Dental changes: Deficits in mastication due to loss or lack of dentition
  • Saliva changes: Older individuals have a decrease in salivary reserve
  • Labial changes: Labial drops occurs earlier and last longer in anticipation of the bolus in older adults
  • Lingual changes: Decreased lingual strength, mobility, and endurance
  • “Tipper” vs “dipper”: Some older adults tend to produce the “dipper” swallow as they age, which slows the oral phase when compared to the “tipper” swallow
  • Swallow onset timing: Delayed 50+ and significantly delayed 65+.
  • Pharyngeal and UES pressure
  • Pharynx is elongated and more dilated
  • Laryngeal changes: lowered to the sixth and seventh vertebrae, decreased flexibility
  • Respiratory changes
23
Q

What are some sensory changes to the swallow system with aging?

A
  • Olfaction
  • Vision/proprioception
  • Audition
  • Tactile
24
Q

Volume driven feeding vs cue based infant driven feeding

A

Volume driven feeding:
- Successful feeding = completion of entire volume during structured feeding times (ex. every 3-4 hours).
- Quantity is the ultimate goal. Baby is expected to finish bottle in a time efficient manner.
- If bottle is not finished, NGT tube placed to finish the remaining feeding.
- Negative outcomes: Baby’s physiologic stability is put at risk.

Cue based infant driven feeding:
- Successful feedng = Teah baby how to PO feed with positive feedback and safety as primary focus.
- Baby’s intake should increase as his/her feeding skills develop with cue-based feeding approach.
- Quality of feeding rather than quantity
- When the priority of the feeder is to provide quality feedings to the infant, it would promote the development of increased oral intake with developmentally appropriate feeding success.

25
Q

A decreased swallow coordination in an infant can cause what?

A

Decreased swallow coordination may cause aspiration, which can result in aspiration pneumonia or lower respiratory tract infections

26
Q
  1. What is tongue thrust swallow?
  2. Can it affect speech?
A
  1. Movement pattern where the tongue moves forward towards (or between) the teeth during swallowing, rather than up against the palate.
    It is the appropriate swallowing pattern for infants and is expected, in most cases, to evolve into a ‘mature’ swallow, where, as an individual ages, they increasingly swallow by pushing the tongue up against the palate.
  2. There may be an association between tongue-thrust swallowing and articulation, especially articulation of /s/ and /z/.
    However, it is important to note that this relationship doesn’t mean that tongue-thrust swallowing causes articulation errors, or that every child or person with a tongue-thrust swallow will have articulation errors. Rather, it may be the case that tongue-thrust swallowing and certain articulation errors have a common underlying cause in some people.
27
Q

When should we be concerned about tongue thrust?

A
  1. If there’s a speech or eating/drinking issue related to tongue thrust. however, if there’s a speech issue, work on the speech issue.
  2. Concernes about dentition, orofacial development, or breathing, we might refer to a dentist or ENT
  3. If there are no functional issues at all, then the tongue-thrust swallow alone probably constitutes a difference or developmental stage, not a disorder.
