Flaccid Dysarthria is also known as ?
Bulbar Palsy
Flaccid Dysarthria is caused by ?
Impairments of LMN in cranial or spinal nerves
Slow labored artic, hypernasal resonance and hoarse breathy phonation are characteristics of _______.
Flaccid Dysarthria
Flaccid dysarthria has a negative impact on what aspects of speech?
Respiration, phonation, artic, prosody and resonance (to different extents)
Flaccid Dysarthria is primarily due to _______ and ______.
muscular weakenss and reduced tone
Flaccid Dysarthria is often _____ UNLESS there is _____ LMN damage.
Mild
bilateral
Flaccid Dysarthria weakness affects ____, ____, and ____.
ROM
Speed
Accuracy
T or F? Speaking on residual volume is typically a characteristic of flaccid syarthria.
False; it is not.
T or F? Breathiness may be unique to flaccid dysarthria.
True
T or F? Audible inhalations/inspiratory stridor may be unique to flaccid dysarthria.
True
T or F? Diplophonia is not characteristic of flaccid dysarthria.
False; it may be unique to flaccid dysarthria.
What are 2 strong confirmatory signs of flaccid dysarthria?
hypernasality and phonatory incompetence
What are 2 strong confirmatory PHYSICAL signs of flaccid dysarthria?
Atrophy and Fasciculations
Caused by anything that disrupts flow of LMN along cranial or spinal nerves that innervate muscles of speech production.
Flaccid Dysarthria
What are the most common causes of flaccid dysarthria?
ALS
Progressive bulbar palsy (PBP)
(brainstem stroke)
What are pt complaints re CN V?
difficulty moving/closing jaw, chewing, arctic, drooling and decreased sensationg to face, cheeks, tongue, teeth or palate
Upper face is bilaterally innervated by what CN?
CN VII
Lower face is contralaterally innervated by what CN?
CN VII
Pt complaints of CN VII ?
Unilateral: Biting cheeks or lips when chewing/speaking, drooling, difficulty keept food/liquid in mouth & artic difficulty.
Bilateral: Face or lips dont move well during speech, drooling, difficulty keeping food/liquid in mouth.
What is one of the most important CNs for speech production?
CN X
Pharyngeal branch of CN X innervates –>
muscles of soft palate for resonance
Superior laryngeal branch of CN X innervates –>
cricothyroid muscles for pitch change
Recurrent laryngeal branch of CN X innervates –>
motor to all intrinsic laryngeal muscles except cricothyroid for phonation
What is the function of CN X?
voice production, VP closure (resonance) and swallowing
Pt complaints of CN X?
loss of pitch range, voice changes, shortness of breath, noise on inspiration, reduced loudness and increased nasality
CN XII _____ innervates the ____.
contralaterally
tongue
Pt complaints of CN X?
Difficulty w/ artic, moving food around in pouth, pocketing, drooling and tongue feels heavy/thick
