Q

How is pressure maintained for speech?

A

Interplay between passive and muscular forces. The amount of muscular forces required depends on the pressure needs and the relaxation pressure available at that lung volume.

Q

T or F: We use checking action during normal speech

A

False- checking action is using inspiratory muscles to decrease pressure in the lungs and slow the exhale. If used in speech it is an impairment.

26
Q

What are the 2 goals of perceptual evaluation?

A
  • Describe the speech breathing abnormality

- Suggest physiologic reasons for these problems and its neuropathologic mechanism

27
Q

4 things to look at in a Physiological Assessment?

A

1) Pressure
2) Vocal intensity
3) Breathgroups
4) Respiratory shapes

28
Q

How do you PERCEPTUALLY assess adequacy of Subglottal Pressure?

A

Goal is 5-8 cmH20

  • Sustained phonation for 15 seconds (if they can do it in non-speech they can do it in speech)
  • Count to 20 on one breath
29
Q

How do you Instrumentally assess adequacy of Subglottal Pressure?

A

Aerodynamic assessment
U-tube manometer
Water-bubble manometer
Hand-held spirometer

30
Q

T or F: Every clinician should have a water bubble manometer

A

True- Cup with 10 cm of water above the end of the straw. Blow for 15 sec.

31
Q

How do you assess Vocal intensity?

A
  • SPL meter - 70db, hold 6-12 cm from the mouth
  • Test in quiet and noisy environment - look at variation across environment
  • Can the person maintain phonation
32
Q

Testing Vocal intensity in a noisy environment is especially important in ____

A

PD

33
Q

Define Breathgroup:

A

A unit of connected speech sparated from another unit by a pause of 200ms or longer

34
Q

How would you assess breathgroups?

A
  • Record a reading passage.
  • Identify pauses longer than 200msec in duration. -
  • Count # of words/ breathgroup.
  • Judge whether locations of pauses is appropriate.
  • Measure pause duration b/w breathgroups and at sentence boundaries
35
Q

How do you assess Respiratory Shapes?

A

Touch people while they perform the task to get kinesthetic info. Muscles contract during inhalation. You may or may not feel something after that.

36
Q

List 6 goals of treatment of respiratory function?

A
  • increase subglottal pressure
  • increase speech intensity (maintain loudness)
  • increase breath group duration (ability to maintain Ps)
  • Use appropriate lung volume range (improve efficiency, prosody)
  • Improve breathing, efficiency
  • Reduce fatigue during speaking
37
Q

Describe the timeline of treatment:

A
  • address medical issue first

Either manage laryngeal, VP and artic first, breathing first or both at the same time.

38
Q

What are 2 common non-speech treatment tasks

A
  • tidal breathing (education about breathing)
  • breathing through a water manometer; blowing - max inhale and exhale/ fast inhale and slow exhale
    Do not expect generalization to speech
39
Q

What are 4 common treatment tasks that involve speech:

A
  • sustained phonation
  • strings of words (automatic and word lists)
  • Phrases of different duration
  • Stress-varying exercise
40
Q

What are some possible postural adjustments for breathing?

A
  • appropriate upright position
  • abdominal binder to support expiratory musculature
  • Expiratory board/ paddle - teach them to use external object (ie. wheelchair), teach them when to lean
41
Q

T or F: Supine breathing helps diaphragm but makes the abdominals work harder.

A

helps abdominals but makes the diaphragm work harder

42
Q

List 3 treatment methods:

A

1) Augmented Feedback
2) Linguistic Approach
3) Strength Training

43
Q

The purpose of augmented feedback is to work on awareness. Options include:

A
  • U-tube or digital manometer for sub-pressure
  • Respitrace or respiratory magnetometer for lung volume and respiratory shapes
  • Acoustic feedback (Visipitch or SPL meter) to monitor loudness
44
Q

Describe the linguistic approach:

A
  • Teach breathgroup structure (simplify syntax)
  • Teach about pausing in normal speech and reading
    - not every pause = inhalation
  • Contrastive stress drills
45
Q

What are the goals of strenght training:

A
  • increase strenght
  • increase endurance
  • changes in muscle size and patterns of activation
46
Q

How would you do strength training vs endurance training:

A

strength training - use heavy loads, small number of reps and lots of recovery

endurance training- light loads but lots of reps

47
Q

T or F: We don’t use strength training in the oral motor system or the respiratory system

A

False - abdominal and intercostal muscles are skeletal muscles and skeletal muscles can benefit from strength training

48
Q

T or F: For strength training we need to be challenged beyond threshold level to get improvements. The increase in load is more important than the increase in frequency to get muscle hypertrophy, recruitment of motor units and increased firing rates, improved synchronization in firing of motor units.

A

True

49
Q

_________ increases inspiratory volume and therefore _____ improve breath group length and lounness.

A

Inspiratory muscle training

may

50
Q

Describe inspiratory muscle training:

A
  • increase inspiratory volume
  • shorten inspiration
  • improve ability to hold inspiratory effort
  • may reduce speaking related dyspnea (shortness of breath) and fatigue
51
Q

Describe expiratory muscle training:

A
  • develop better control over the expiratory phase
  • prolong expiratory flow
  • may decrease speaking related dyspnea and fatigue
52
Q

Inspiratory and expiratory muscle training are _________ exercises. Do not expect generalization to speach breathing without speech breathing intervention.

A

non-speech

53
Q

How does loaded inspiration/ expiration work:

A
  • breath against resistance
  • determine patient’s max capacity (30 cmH20)
  • determine target (70% of max)
  • patient will inspire thru device for 2 min with 1 min recovery. Repeat 8-10 times.
  • perform X# of weeks
  • As max inspiratory pressure improves increase the target
54
Q

What professionals should SLP consult/ work with for breathing?

A

Respiratory therapist
occupational therapist
physiotherapist
