Dysarthria
Stack #56942
| Question | Answer |
|---|---|
| Dysarthria | Speech disorder resulting from paralysis, weakness, or incoordination of the speech musculature that is of neurologic origin |
| Encompasses motor distrubance of | respiration, phonation, resonance, articulation, prosody |
| Can be a disorder of | pryamidal system, extrapyramidal, cerebellar system |
| Pyramidal damage | prognosis is good (CVA) |
| Upper Motor Neuron Lesion | Corticobulbar tract spatic |
| Lower Motor Neuron Lesion | Medulla or Pons, Cranial nerves flaccid |
| UMN dysarthria | mild or transitory symptoms, damage usually unilateral |
| UMN Articulation | imprecise |
| UMN Prosody | slowed rate |
| UMN Resonation | Harshness, reduced loudness and hypernasality |
| Spastic Dysarthria voice | harsh strangle strained, lower pitch, monotone |
| Spastic Dysarthria respiration | breathiness |
| Spastic Dysarthria atriculation | imprecise consonants and vowel distortion |
| Spastic Dysarthria resonation | hypernasality velum doesn't elevate |
| Spastic Dysarthria prosody | Excess equal stress |
| Emotional labiality | tendency to cry or laugh at the slightes provocation although they do not feel all that sad or happy (spastic dysarthria) |
| Lower Motor Neuron Dysarthria | Flaccid |
| Flaccid Dysarthria voice | monotone |
| Flaccid Dysarthria respiration | nasal emissions, audible inspirations (strider) |
| Flaccid Dysarthria articulations | imprecise consonants especially plosives |
| Flaccid Dysarthria resonation | breathiness or harsh and loud, hypernasality |
| Flaccid Dysarthria other | diminished reflexes, fasciculations, atrophy |
| Disorders of the extrapyramidal system | basal ganglia dysarthria |
| basal ganglia dysarthria | hypokinetic, hyperkinetic |
| hypokinetic dysarthria voice | soft phonation, drops off at the end, can't hardly hear |
| hypokinetic dysarthria articulation | decreased range of movements, thus articulatory impresision "articulatroy undershoot" |
| hypokinetic dysarthria prosody | variable rate--rapid, indistict, normal, inappropriate pauses. Short utterances |
| hyperkinetic dysarthria articulation | involuntary movements break the force, timing or amplitude of speech movements (uneven, jerky artic) |
| hyperkinetic dysarthria voice | intensity and pitch fluctuations. (jerks) |
| hyperkinetic dysarthria prosody | abnormal silent intervals |
| hyperkinetic dysarthria voice | hoarse-strangled voice quality |
| hyperkinetic dysarthria Atriculation | prolonged phonemes |
| hyperkinetic dysarthria prosody | variable |
| Ataxic Dysarthria articulation | inconsistent consonant misarticulations |
| Ataxic Dysarthria articulation | coarse-loudness variations (inconsistent) |
| Ataxic Dysarthria resonance | normal or may fluctuate from nasal to non-nasal |
