Lee Silverman Voice Treatment

The Lee Silverman Voice Treatment (LSVT®) is the first effective treatment established for treating the voice and speech disorders in individuals with Parkinson disease and other neurological disorders.


LSVT Information:

  • Improves both the voice and speech of individuals with Parkinson disease

  • Treats the underlying physical pathology associated with the disordered voice

  • In Level I efficacy studies, over 400 individuals with Parkinson disease have been successfully treated with the LSVT

  • 90 percent of patients improve from pre to post-treatment

  • Approximately 80 percent of patients maintain voice treatment improvements for 12-24 months post-treatment

  • All patients report improvement in their ability to communicate

  • Intensive therapy includes 16 visits (4 days a week, for 4 weeks) with a speech pathologist

The National Jewish Health Rehabilitation Department has three LSVT® trained and certified speech-language pathologists.
