LSVT LOUD Fact Sheet

LSVT LOUDTM is the first speech treatment with level 1 evidence and established efficacy for treating voice and speech disorders in individuals with Parkinson’s Disease.


LSVT LOUDTM improves both the voice and speech of individuals with Parkinson’s Disease by treating the underlying physical pathology associated with the disordered voice.

  • Treatment focuses on improving vocal loudness and immediate carryover into daily communication enabling patients to maintain and/or improve their oral communication.
  • LSVT LOUDTM is administered on an intensive schedule of 16 individual, 60 minute sessions over a one-month period.
  • 90% of clients improve vocal loudness from pre- to post-treatment.
  • Approximately 80% of patients maintain treatment improvements in their voice for 12-24 months post-treatment.
  • All patients report improvement in their ability to communicate.
  • LSVT LOUDTM is being successfully delivered by over 10,000 certified LSVT clinicians in 52 countries.*

Please note: because it is a high intensity program, clients attending LVST LOUDTM require an Ear Nose and Throat specialist (ENT) referral or clearance before treatment commences.
