ASLHC is proud to now offer LVST as a treatment option for patients with Parkinson’s Disease! If you or your loved one would be a candidate for this treatment, please contact our center. One of our SLPs is specially trained in this research-based treatment. This is also a viable treatment option for patients with moderate to severe dysarthria or another muscular dysfunction (not including ALS).

LSVT LOUD is the first speech treatment with level 1 evidence and established efficacy for treating voice and speech disorders in people with Parkinson disease (PD) with application to other neurological disorders.

The LSVT Programs have been developed and scientifically researched over the past 25 years with funding from the National Institutes of Health. LSVT LOUD outcome data have been published in a series of refereed articles in speech, otolaryngology and neurology journals.

Research on LSVT LOUD has documented improved impact on multiple levels of functioning in people with PD following treatment including:

  • Increased vocal loudness
  • Improved articulation and speech intelligibility
  • Improved intonation
  • Improvements in facial expression
  • Changes in neural functioning related to voice and speech

LSVT LOUD is a standardized treatment protocol that is customized to the unique communication goals of each person across a range of disease severity and communication impairments.

LSVT LOUD treatment consists of:

  1. 16 sessions: four consecutive days a week for four weeks
  2. Individual 1-hour sessions
  3. Daily homework practice
  4. Daily carryover exercises

It is essential that LSVT LOUD treatment is only delivered by speech-language pathologists who are certified in this method.

Over 24,000 speech therapists from 70 countries have been certified in LSVT LOUD.
