what is hypokinetic dysarthria
decreased mobility of ROM
- not decreased muscle
- decreased movement
what are 3 common characteristics of hypokinetic dysarthria
1. decreased loudness
2. harsh or breathy vocal quality
3. abnormal speaking rate (slow or rapid)
what are two unique characteristics of hypokinetic dysarthria
1. increased rate of speech may be one of the symptoms
2. majority of cases share the same etiological factor
what is the major etiological factor of hypokinetic dysarthria
parkinsonism
what are three symptoms of parkinsonism that affect speech
1. muscle rigidity
2. reduced ROM
3. slowed movement
symptoms of parkinsonism are caused by
dysfunction in BG or damge to the BG control circuit
what are 5 characteristics of parkinsonism
1. tremor (resting tremor)
2. bradykinesia
3. akinesia
4. muscular rigidity
5. impaired postural reflexes
tremor
- most commonly invovles...
- most noticable while the body is
- most commonly involves the hands and fingers but can also involve the limbs and face
- most noticeable while the body is not moving; tend to decrease during voluntary movement
bradykinesia is...
- results from....
- slow and reduced ROM
- a result of dysfunction of the BG, NOT a result of muscle weakness
Akinesia is...
can be...
- a delay in the initiation of movements
- can become "stuck" in a posture of trouble stopping a movement once it is started
muscular rigidity is due to
- it is

- person may present with
increased muscle tone- resistance to the movement

- slowness of movement and a feeling of stiffness or tightness

- with a constant resistance to movement or an intermittent change in resistance
Impaired postural reflexes (2)
1. difficulty maintaining balance when walking
2. difficulty rising from a chair



** diff initiating movement
** damage to EPS
what are 4 other common parkinsonism characteristics
- depression
