__________________, ______________, and ______________can cause speech deficits
Muscular weakness, deficient neural control, and growth deficiencies
Oral mechanism exam- need to know the degree of
abnormality, not just presence or absence of abnormality
Lips:
only gross structural abnormalities of the lips actually cause speech disorders, like cleft lip (once they get cleft lip surgically repaired they still may not have a completely normal structure but they can still produce speech sounds)
Teeth: f, v, th
Sometimes it can affect speech production but it doesn’t necessarily affect speech production (studies of preschoolers)
3 types of malocclusions:
Dental arch malocclusions don’t necessarily cause speech deficits;
can be a contributing factor but not necessarily
Tongue:
very adaptable organ, can compensate very well when there is an extensive amount missing. A lot of the tongue can be missing and the person will still have good speech intelligibility.
Ankyloglossia:
a short lingual frenulum, must be at least moderate to severe to cause speech disorder (some believe it can cause trouble with infant feeding)
Glossectomy:
total or partial surgical removal of the tongue
Hard Palate
quite a variation of palate height and width, normal variations don’t affect speech production. Must be a gross deficit, like cleft palate, cancer of the
palate and removal (can get palatal prosthesis and have normal speech)
Soft Palate: velum
Results of velopharyngeal inadequacy
Motor skills
-diadochokinetic rates
• Adult normal between the ages 9-15
• Children will be quite a bit slower
o The slower rate doesn’t mean there will be a motor speech disorder
• It is helpful in identifying childhood/adult apraxia
Oral Sensation
* Studied through anesthesia in mouth and assessing speech, no decrease in intelligibility found
Language skills
Personal Characteristics
• Age: younger children have more speech disorders than older children but by 1st grade they should match the adult model
Gender
Intelligence
Socioeconomic status
• No significant difference in speech disorders
Familial prevalence
• Family by family basis, not always hereditary but can be
Tongue Thrust
Tongue Thrust
Characterized by: forward gesture of the tongue during swallowing
This can cause
• Interdentalization of t, d, n, l
• Frontal lisp of s and z
• Anterior placement of the palatals
Use tongue and jaw _________techniques to target
r, l, s
stability
Speech screening
• Pass or fail procedure that can be conducted on a large amount of individuals in a relatively short period time
• Helps identify children who potentially have a speech or phonological disorder
• Does no mean that child has disorder- let parents know that
o Does mean they should be sent for more in depth testing
• Conducted in schools: pre-K-1st grade (beginning of the year)
• In hospital: altered mental status, stroke, brain injury (injury- may be called in to look at cognitive, speech, language, etc (mini mental state examination)
• Mini Mental State Examination: orientation to person, time, and place, memory recall, writing, and counting tasks
