LSVT BIG® is an intensive, amplitude focused physical and occupational therapy approach developed from principles of the effective Parkinson's specific speech treatment LSVT LOUD®.

The LSVT Programs have been developed and scientifically researched over the past 25 years with funding from the National Institutes of Health (NIH).

Research on LSVT BIG® has documented improved ratings on tests of motor functioning in people with Parkinson's Disease following treatment, including:

  • Faster walking with bigger steps
  • Improved balance
  • Increased trunk rotation
  • Improvements in activities of daily living such as bed mobility
  • Improved UPDRS Motor Score

LSVT BIG® is a standardized treatment protocol, which is customized to the unique goals of each patient including both gross and fine motor skills. LSVT BIG® can be adapted or progressed to meet each patient's needs across a range of disease severity and presenting impairments.

LSVT BIG® treatment consists of:

  • 16 sessions - 4 consecutive days a week for 4 weeks
  • Individual one-hour sessions
  • Daily homework practice
  • Daily carryover exercises

It is essential that LSVT BIG® treatment is only delivered by physical and occupational therapists who are certified in this method.

LSVT BIG is being delivered by over 10,000 certified LSVT clinicians in 38 countries.
