Flaccid dysarthria is a motor speech disorder resulting from damage to peripheral nervous system (cranial or spinal nerves) or lower motor neuron system. Depending on which nerves are damaged, flaccid dysarthria affects respiration, phonation, resonance, and articulation. It also causes weakness, hypotonia (low-muscle tone), and diminished ...
The most common types of dysprosody are associated with dysarthria and developmental coordination disorder, which affect motor processing in speech. Among the most studied types are: Flaccid dysarthria is characterized by little control over pitch and voice volume, reduced speech rate, and impaired voice quality
Dysarthria is the reduced ability to motor plan volitional movements needed for speech production as the result of weakness/paresis and/or paralysis of the musculature of the oral mechanism needed for respiration, phonation, resonance, articulation, and/or prosody.
Dysarthria is a speech sound disorder resulting from neurological injury of the motor component of the motor–speech system [1] and is characterized by poor articulation of phonemes. [2] It is a condition in which problems effectively occur with the muscles that help produce speech, often making it very difficult to pronounce words.
Dysarthria is a weakness or paralysis of speech muscles caused by damage to the nerves or brain. Dysarthria is often caused by strokes, Parkinson's disease, [9] ALS, head or neck injuries, surgical accident, or cerebral palsy. Aphasia; Dysprosody is an extremely rare neurological speech disorder. It is characterized by alterations in intensity ...
One major characteristic used to identify a lower motor neuron lesion is flaccid paralysis – paralysis accompanied by loss of muscle tone. This is in contrast to an upper motor neuron lesion, which often presents with spastic paralysis – paralysis accompanied by severe hypertonia.
Dysarthria is a motor speech disorder that results from a neurological injury. Neurodegenerative conditions like Parkinson's disease, amyotrophic lateral sclerosis, and progressive supranuclear palsy frequently transpire in association with dysarthria. [6] Some stem from central damage, while other stem from peripheral nerve damage.
A speech sound disorder (SSD) is a speech disorder affecting the ability to pronounce speech sounds, which includes speech articulation disorders and phonemic disorders, the latter referring to some sounds not being produced or used correctly.
