Dysarthria is a condition in which a person have problems controlling the pitch, loudness, rhythm, and voice qualities of his or her speech. It is mainly caused by paralysis, weakness, or inability to coordinate the muscles of the mouth. Articulation problems resulting from dysarthria are treated by speech language.
Any damage to the neuromuscular system regulates the speech fine motor control of speech production may be disrupted. Impairment of any basic motor process results the execution of speech. The activity of speech under the articulatory movements of the speech organs it must be under the control of neuromuscular system.
Treatment depends on effect the dysarthria has on control of the articulators. More recent techniques based on the principles of motor learning (PML), such as LSVT (Lee Silverman voice treatment)speech therapy and specifically LSVT may improve voice and speech function in PD. Augmentative and alternative communication (AAC) devices that make coping with a dysarthria easier include speech synthesis and text-based telephones.
Around 85% of cases arise from strokes and around a third of people who have strokes will have dysarthria. dysarthria recorded in 9/27 (33%), 8/27 (30%) and 9/27 (33%) cases, respectively.
