It is a motor speech disorder resulting from neurological injury of the motor component of the motor-speech system. Dysarthria that has progressed to or presents as a total loss of speech may be referred to as anarthria. 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. Traditional treatments target the correction of deficits in rate (of articulation), prosody, intensity. More recent techniques based on the principles of motor learning (PML), such as LSVT (Lee Silverman voice treatment). 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.
