Motor Speech Disorders Flashcards
dysarthria
speech disorder caused by neurologic damage
AOS
neurologically based motor programming disorder —difficulty producing the correct sounds in correct order
CN V function & change in speech
trigeminal
motor: mastication muscles
sensory: face & mucous surfaces of eyes, tongue, & parts of nasoapharyneal space
damage – imprecise consonants, distorted vowels, slow rate
CN VII function & change in speech
Facial
motor: facial muscles
sensory: ant 2/3 of tongue
damage: distortion of bilabial, labiodental sounds, slow rate
CN X function & change in speech
Vagus
motor & sensory to muscles of the soft palate, pharynx, and larynx
damage: breathiness, decreased loudness, short phrases, hyper nasality, nasal emission, weak plosives (possible hoarseness if unilateral)
CN XII function & change in speech
hypoglossal
innervation of tongue muscles
damage: mild-sever consonant imprecision vowel distortion
planning
selecting the sounds you want to say
programming
how to move from 1 sound to the next, fine movements

what to include in SUMMARY & FORMULATION on comps
- diagnosis
- severity
- describe the speech and motor impairments
- relate it to the neurological damage
- discuss the major limiting features
- prognosis and recommendations
Severity - Mild (Langmore)
- just barely dysarthric
- completely intelligible
- artic impaired <10% of words
- voice &/or resonance may be slightly impaired
Severity - Mild/Mod (Langmore)
- definitely dysarthric
- intelligible except for occasional words
- artic impaired 10-30% of words
- errors involving only a few consonants
- voice &/or resonance are impaired
Severity -Moderate (Langmore)
- speech sometimes difficult to understand
- artic impaired 30-50% of words
- errors involving many consonants & occasional words
- some combo of resonance, voice, speech, rate & prosody impaired
Severity - Mod/Severe (Langmore)
- speech is often difficult to understand
- atic impaired 50-70% of words
- Resonance, voice, speech rate, & prosody all affected
Severity - Severe (Langmore)
- speech is often unintelligible
- artic impaired 70-90% of words
- errors involving nearly all consonants and some vowels
- Resonance voice, speech rate, & prosody are all affected
