Disorders & Respiration

• Parkinson's disease – Changes in chest-wall shape – Reduced rib cage movement– Increased displacement of abdomen – Reduced VC

– Reduced Poral

Understanding Parkinson’s Disease

Disorders & Respiration

• Cerebellar disease – Reduced VC – Abrupt changes in

motions of the chest wall

– Utterances initiated below normal lung volumes

Cerebellar Disease

Disorders & Respiration

• Cervical spinal cord injury – Reduced VC, IRV, and ERV – Larger than normal lung

volumes at beginning and ending of speech exhalation

– Larger abdominal volumes than normal

– Fewer than normal syllables per breath

Spinal cord injuryChristopher Reeve

Disorders & Respiration

• Cerebral palsy– Reduced VC – Difficulty accessing IRV and ERV – Weakness and deformities of

chest wall – Abnormally high airflows during

speech

Disorders & Respiration

• Mechanical ventilation – Higher than normal

Ptrach

– Excessively high TV

Passy-Muir Valve with Mechanical Ventilation

Disorders & Respiration

• Voice problems – Clavicular breathing – Higher than normal P

trach – Higher lung volume

initiation– Lower lung termination

for speech

Disorders & Respiration

• Hearing problems – Exhaling for speech at

low lung volumes – Excessive air

expenditure per syllable
