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.
Notable techniques include, but are not limited to, the yawn-sigh method, optimal pitch, laryngeal manipulation, humming, the accent method, and the Lee Silverman Voice Treatment. [9] [38] An example of a direct therapy is circumlaryngeal manual therapy, which has been used to reduce tension and massage hyoid-laryngeal muscles. [12]
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 ...
For most children, the disorder is not lifelong and speech difficulties improve with time and speech-language treatment. Prognosis is poorer for children who also have a language disorder, as that may be indicative of a learning disorder. [8] There are several treatments available which depends on the cause of speech sound disorders:
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 ...
Dysphagia, dysarthria, flaccid paralysis, muscle atrophy, drooling of saliva, reduced or absent gag reflex Bulbar palsy refers to a range of different signs and symptoms linked to impairment of function of the glossopharyngeal nerve (CN IX), the vagus nerve (CN X), the accessory nerve (CN XI), and the hypoglossal nerve (CN XII).
This disorder is characterized by the adult-onset triad consisting of the following symptoms: sensory ataxic neuropathy, dysarthria, and ophthalmoparesis. MRIS often reveals white matter abnormalities and bilateral thalamus lesions. Other symptoms include generalized myopathy, epilepsy, and deafness. [1] [2]
Management options can be subdivided into medical treatment and rehabilitation interventions. Medical treatment consists of oral medication and surgery. Before using oral drugs, it is important to differentiate between spasticity , dystonia and choreoathetosis since each motor disorder has a specific approach.
