Disorders & Respiration Parkinson's disease –Changes in chest-wall shape –Reduced rib cage movement –Increased displacement of abdomen –Reduced VC –Reduced P oral Michael J. Fox 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 injury Christopher Reeve

Disorders & Respiration Cerebral palsy –Reduced VC –Difficulty accessing IRV and ERV –Weakness and deformities of chest wall –Abnormally high airflows during speech Zachary’s cerebral palsy Zachary learns to say his name

Disorders & Respiration Mechanical ventilation –Higher than normal P trach –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 Dr. Sims and voice disorders

Disorders & Respiration Hearing problems –Exhaling for speech at low lung volumes –Excessive air expenditure per syllable Aiden’s speech
