1
Q

hypokinetic dysarthria

A

caused by any process that damages basal ganglia (extrapyramidal system)

2
Q

speech characteristics of hypokinetic dysarthria

A

harsh vocal quality, reduced stress, monoloudness, imprecise consonants

3
Q

hypokinetic dysarthria will only be seen in

A

parksinson’s disease, parkinsonism

4
Q

parkinsonism

A

know the etiology

5
Q

parkinson’s disease

A

etiology is unknown

6
Q

hypo and hyper refer to

A

range of movement

7
Q

neurologic basis of hypokinetic dysarthria

A

unique as only dysarthria with increased rate of system, mainly one causative factor, symptoms caused by dysfunction to basal ganglia or to basal ganglia’a neural connections to other parts of CNS

8
Q

characteristics of parkinsonism

A

resting tremor, bradykinesia, rigidity, spasticity, akinesia, postural reflexes

9
Q

resting tremor

A

males more effected than females; hands are shaking without doing anything

10
Q

bradykinesia

A

slow, reduced range of movement

11
Q

rigidity

A

tight muscle tone from start to finish

12
Q

akinesia

A

delay in initation of movements

13
Q

causes of parkinsonism

A

caused by dysfunction in basal ganglia

14
Q

dopamine

A

inhibitory

15
Q

acetylcholine

A

excitatory

16
Q

causes of hypokinetic dysarthria

A

-parkinsonism: collective term for different disorders sharing many similar symptoms
-idiopathic PD
neuroleptic-induced parkinsonism
postencephalitic parkinsonism
traumatic head injury
toxic metal posioning
stroke

17
Q

speech characteristics of hypokinetic dysarthria

A

most notable errors: prosody and articulation

18
Q

speech characteristics prosody

A

monopitch, reduced stress, and monloudness, festinating speech

19
Q

speech characteristics artic.

A

imprecise consonants, repeated phonemes, palilalia

20
Q

speech characteristics phontion

A

harsh/breathy quality, aphonia, low pitch

21
Q

speech characteristics respiration

A

sometimes noted

22
Q

speech characteristics resonance

A

if present, mild hypernasality

23
Q

key evaluation tasks for hypokinetic dysarthria

A

conversational speech and reading, speech alternate motion rates (AMRs), vowel prolongations

24
Q

treatment of hypokinetic dysarthria

A

pharmacologic, surgical, behavioral

25
Q

pharmalogic treatments

A

replacing dopamine in striatum; L-Dopa; correct neurotransmitter imbalance by decreasing acetylcholine activity in striatum

26
Q

surgical treatments for parkinsonism

A

complicated and invasive, used when patient incapacitated and medications ineffective, two general types

27
Q

stem-cell implantation

A

stem cells unique as can transform themselves into different types of cells, found naturally in embryos and can be grown in labs, significant amount of research concentrated on using stem cells to treat parkinsonism

28
Q

behavioral treatments

A

speech-therapy

29
Q

artic. treatment

A

compounded by increased rate, treatment types; rate reduction, stretching, taditional artic. tasks

30
Q

phonation

A

adduct VFs on partially or have harsh or breathy vocal quality; pushing and pulling procedure, hard glottal attack, voice amplifiers, instrumental biofeedbacks, Lee Silverman Voice Treatment

31
Q

respiration

A

shallow breath support can cause shortened phrases and decreased loudness; speaking immediately on exhalation, cueing for complete inhalation, slow and controlled exhalation, stop phonation early

32
Q

prosody

A

improved by slowing rate; intonation profiles, contrastive stress drills, chunking utterances ino syntactic units
