[Speech therapy of dysarthria in Parkinson's disease].

The treatment of speech impairment, a factor of loneliness, speech therapy to treat dysarthria in Parkinson's disease is a fundamental aspect of patient management. The impact of medicinal treatment of dysarthria is controversial and surgery appears to worsen the problem. Various speech therapy approaches are relaxation, postural rehabilitation, respiration, phonation, articulation and prosodic re-education. AN INTERESTING METHOD: This overview underlines the fundamental principles of speech therapy in Parkinson's disease and compares the main methods and their results. We particularly insist on the Lee Silverman Voice Treatment (LSVT), phonation re-education method that has been widely developed in the United-States. Our aim is to provide better knowledge on this re-education method in France.
