3 Phases of Swallowing
Oral Pharyngeal Esophageal

Normal Swallow Sequence

Normal Swallow Sequence
In the mouth: lips, teeth and tongue
help prepare bolus (food mass) for further stages of swallowing.

Normal Swallow Sequence
Access between the nasal cavity and mouth closes as bolus moves into pharynx (throat).

Normal Swallow Sequence
Bolus is propelled esophagus
As esophagus entrance opens: Epiglottis helps guard against access to the lungs.Epiglottis

Normal Swallow Sequence
The airway reopens and the esophagus entrance closes as muscle contractions move bolus toward stomach.

Safe Swallowing Strategies
Swallowing techniques Don’t talk with mouth full Repeat swallows Alternate solids and liquids
One sip at a time Sip ‘n’ tip straws Smaller bites Slowed rate Supervision and cueing Smaller, more frequent meals per day
![Page 21: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/21.jpg)

Alternative Methods of Nutrition
![Page 25: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/25.jpg)
Feeding Tubes
G-tube goes into stomach through an opening in skin
![Page 26: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/26.jpg)
Feeding Tubes [cont.]
What it does: Provides nutrition via an alternate route Allows one to receive required nutrition and
hydration when no diet texture can be swallowed safely or when oral feeding is not meeting nutritional / hydration needs
Allows for the combination of oral eating for pleasure and tube feeding for fluids and calories
![Page 27: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/27.jpg)
Ataxia and Speech
![Page 28: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/28.jpg)
Speech
“Normal” sounding speech requires perfect coordination of the following systems: Articulatory system (e.g., lips, tongue, etc.) Resonatory system (e.g., velum/soft palate) Phonatory system (e.g., vocal cords) Respiratory system (e.g., lungs)
![Page 29: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/29.jpg)
Random Speech Facts…
Approx. 14 different sounds produced every second when we verbalize.
Over 100 different muscles coordinate during speech.
![Page 30: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/30.jpg)
“Its Greek to Me”
Ataxia comes from: Greek word for “lack of order”
![Page 31: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/31.jpg)
Ataxic Dysarthria
Disorder of sensorimotor control for speech production that results from damage to cerebellum or to its input and output pathways
![Page 32: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/32.jpg)
Effects of Ataxia on Speech
![Page 33: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/33.jpg)
Effects of Ataxia on Speech
Articulation: disruption of the timing, force, range, and direction of movements. Imprecise consonant articulation Distorted vowels
Breakdown is most evident during longer strings of speech
![Page 34: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/34.jpg)
Effects of Ataxia on Speech [cont.] Resonance:
Hypernasality Hyponasality
May occur due to timing errors between the muscles of the velum and the other muscles of articulation.
Soft Palate / Velum
![Page 35: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/35.jpg)
Effects of Ataxia on Speech [cont.] Phonation: the sound of the voice
Harsh vocal quality due to decreased muscle tone
Vocal tremor
![Page 36: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/36.jpg)
Effects of Ataxia on Speech [cont.] Respiration:
Uncoordinated movements of the respiratory muscles Exaggerated movements
Excessive loudness Paradoxical movements (different muscle
groups work against each other) Talking too quickly Decreased vocal volume Trying to talk on residual air
![Page 37: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/37.jpg)
Most Common Speech Changes Imprecise consonants Excess and equal stress Articulatory breakdown Distorted vowels Harsh vocal quality Mono pitch/Mono loudness Slowed speech rate
![Page 38: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/38.jpg)
Treatment
![Page 39: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/39.jpg)
What to do about it…
1. Evaluation by a Speech-Language Pathologist
2. Treatment Exercises will target the affected system(s)
Improve breath support and coordination of breathing and speaking
Rate control techniques (e.g., finger/hand tapping to set the pace of appropriate syllable production)
Increase articulatory accuracy: over-articulate Develop stress and intonation skills to regulate
pitch and loudness
![Page 40: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/40.jpg)
Compensatory Strategies
For the Speaker... Energy conservation Minimize environmental noise/distractions Establish context of message Alter your rate of speech…SLOW it down. Exaggerate articulation of final consonants
in words Use gestures/point to props Boil down the message
decrease “filler” words Keep important/key words
![Page 41: 2011 Annual Membership Meeting SPEECH & SWALLOWING Anne G. Lefton, M.A. / CCC-SLP Nancy Sedat & Associates](https://reader030.vdocuments.site/reader030/viewer/2022032702/56649cd75503460f9499fc0a/html5/thumbnails/41.jpg)
Compensatory Strategies
For the Communication Partner… Ascertain patients preferred strategy when not
intelligible Decrease the need for repetition fatigue and
frustration Ask yes/no questions Know the topic Maintain eye contact Give undivided attention Don’t interrupt or finish sentences Let the speaker know the parts of the message
you did not understand so s/he will not have to repeat the entire message.
Patience
