Q

what are the speech features of facial palsy? (focal flaccid dysarthria) …. why does it occur?

A

imprecise consonants

occurs bc of lip weakness, bilabial and labiodentals may be distorted (may not be distorted in unilateral, but yes in bilateral)

Q

moebius syndrome

A

rare, non-progressive congenital condition that results from the underdev of facial nerves that control some eye/facial movements

“ventriloquist” = may use compensatory movements bc they cannot move their face to create bilabials, ex. w tongue

Q

what are the nonspeech features of palatopharyngeal palsy? (focal flaccid dysarthria) - unilateral

A

weak side of palate hangs lower at rest

deviates to side of strength on elevation

17
Q

what are the nonspeech features of palatopharyngeal palsy? (focal flaccid dysarthria) - bilateral

A

palate symmetric but lower than normal

reduced or absent elevation

diminished or absent gag reflex

nasal regurgitation of liquids

18
Q

what are the speech features of palatopharyngeal palsy? (focal flaccid dysarthria) - unilateral and bi

A

hypernasality

nasal emission of air

imprecise consonants

19
Q

what are the speech features of palatopharyngeal palsy? (focal flaccid dysarthria) - unilateral

A

usually mild or normal

20
Q

what are the speech features of palatopharyngeal palsy? (focal flaccid dysarthria) - bilateral

A

hyper nasality and nasal emission can be quite severe

imprecise consonants involving plosives, fricatives, and affricates bc of reduced intraoral pressure

nasal resonance (i.e. nasal formant) may also distort consonant sounds

21
Q

what is the % of laryngeal palsy (flaccid dysphonia) from duffy 2020

22
Q

what are the nonspeech features of laryngeal palsy? (focal flaccid dysarthria) - unilateral

A

one vocal fold remains stationary and slightly abducted or makes very weak movements towards the midline

weak or incomplete contact bw folds

reduced cough and aspiration problems

23
Q

what are the nonspeech features of laryngeal palsy? (focal flaccid dysarthria) - bilateral

A

both vocal folds remain stationary, slightly abducted (paralysis) or make very weak contact

in paralysis the restricted airway opening requires surgical intervention (tracheotomy or artyneoid surgery)

24
Q

what will you especially hear in those with bilateral laryngeal palsy? (focal flaccid dysarthria)

A

audible inspirations (inhalatory stridor, vibration on inhalation signal)

25
Q

what are the speech features of laryngeal palsy? (focal flaccid dysarthria) (both bi and unilateral)

A

breathy voice

short phrases

reduced loudness

monopitch and monoloudness

diplophonia

harsh voice (bc of jitter/shimmer)

26
Q

what is the % of hypoglossal palsy from duffy 2020

27
Q

what are the nonspeech features of hypoglossal palsy? (focal flaccid dysarthria) (both bi and unilateral)

A

loss of tongue strength and atrophy

swallowing probs

28
Q

what are the nonspeech features of hypoglossal palsy? (focal flaccid dysarthria) - unilateral

A

deviation to side of weakness on protrusion

29
Q

what are the nonspeech features of hypoglossal palsy? (focal flaccid dysarthria) - bilateral

A

reduced range of movements if severe

30
Q

what are the speech features of hypoglossal palsy? (focal flaccid dysarthria) - (uni and bilateral)

A

imprecise consonants

linguo-palatal consonants can be sig impaired (s, z, sh, t, d, k, g, ch, etc)

31
Q

what is the % of respiratory weakness (cervical and thoracic) from duffy 2020

32
Q

what are the nonspeech features of resp weakness (spinal cervical and thoracic)? (focal flaccid dysarthria)

A

frequent shallow inspirations

shortness of breath and reduced vital capacity

postural or clavicular movements during inhalation

blueness of lips or finger nails

A

short phrases

reduced loudness
