Show Answers:

  1. Degenerative neurological diseases
    • Parkinsons
    • Wilsons
    • Progressive Nuclear Palsy
    • Dystonia
    • HD
    • ALS
    • MS
  2. Nonprogressive neurological conditions
    • Stroke
    • Infections
    • TBI
    • Surgical Trauma
  3. Ataxic
    • Damage to cerebellar system
    • Gait disturbances (hyptonia, instability of head and trunk)
    • Movement disorders - over/undershooting of targets, uncoordinated, slow, jerky, imprecise, halting
  4. Flaccid
    • Damage to the LMN
    • Associated with ALS, mysathenia gravis
    • Cranial nerves affected: V, VII, IX, X, XII
    • Fasiculations, fibrillations (contraction of indiviudal muscles), atrophy
  5. Hyperkinetic
    • Damage to basal ganglia
    • Involuntary movement, prosodic disturbances are dominant, tremor, chorea, tics
  6. Hypokinetic
    • Damage to basal ganglia
    • Associated with Alzheimer's, Parkinsons, Progressive supranuclear palsy
    • Tremors in the resting position, micrographic writing (small), mask-like face, walking disorders, postural disturbances
  7. Spastic
    • UMN pathways
    • Hyperadduction of VF, inaqueate VP closure, movements disorders (reduced range, slowness, loss of fine and skilled movements, increased muscle tone)
  8. ALS
    Flaccid-Spastic
  9. MS
    Ataxic-Spastic
  10. Unilateral Upper Motor Neuron
    • Associated with aphasia, dysphagia, apraxia, RH syndrome
    • Unilateral lower face weakness, unilateral tongue weakness, hemiparesis/plegia
  11. Dysarthric movements involving lip-smacking, spastic chewing, grimacing, and protruding the tongue are particularly  associated with
    Tardive dyskinesia, a¬† late-developing disorder similar to chorea and often caused by long-term use of antipsychotic drugs, is associated with hyperkinetic dysarthrias of the predominately quick subtype and characterized by spasmodic facial movements involving tongue-protrusions (so-called “fly-cather’s movements), grimacing, chewing, and lip-smacking
  12. Harsh voice quality
    ~spastic
  13. Hypernasal voice quality
    ~flaccid
  14. Athetosis
    Slow, arrhythmic, writhing, and involunary movements of the extremities
  15. Fly-Cather's Movements
