Transcript of Physiology of Articulation & Resonation: Dysarthria

Dysarthria Physiology of Articulation & Resonation: Dysarthria When airflow and sounds waves are directed
through the pharynx to the oral or nasal cavity Articulation TONGUE VELUM TEETH  When someone speaks they use their articulators to shape their oral cavities to produce speech Manner & Placement Articulators MANDIBLE ALVEOLAR RIDGE HARD PALATE Velopharyngeal Process •Why is articulation and resonation
important to Dysarthria? Motor speech disorder that weakens the muscles of the face, mouth, and respiratory system Causes Symptoms Cerebral Palsy Head/ Brain Injury Muscle Dystrophy Neck Cancer Stroke Parkinson's Disease Multiple Sclerosis Lyme Disease Slurred speech Slow or rapid rate of speech Hardly speak louder than a whisper Drooling Monotone speech Raspy voice Types Hyperkinetic Ataxic Flaccid Spastic Hypokinetic Prognosis Poorly fitted dentures Stroke/Brain Injury ALS or Lou Gehrig's Disease MS or Parkinson's Disease After surgery to tongue or larynx Examinations •Respiratory function
•Sustained phonation
•Soft palate movement
•Laryngeal function
•Cranial nerve examination Coordinated Speech
