LSVT® BIG is an exercise treatment program for people with Parkinson’s disease (PD). It is based on the principle that the brain can learn and change (neuroplasticity). It has been formulated from an existing program to help with speech for people with PD called the Lee Silverman Voice Treatment (LSVT). Research on LSVT use over the last 15 years has shown that it results in improvements in speech intelligibility and voice loudness. LSVT BIG works on the same principle, using a single therapy focus (BIGNESS of movement) to improve movement quality in PD.
People with PD have trouble moving normally. Their movements are usually slower and smaller and they may shuffle or freeze when they walk. Some experience falls and problems with their balance. For most, movement problems can be overcome temporarily when they are “cued” or prompted (either by themselves or by another person or thing) to move better (i.e. “take a big step”, “stand up straight”).
How does LSVT BIG work?
The aim of the intensive LSVT BIG training is improve people’s ability to make bigger movements. These movements can then be generalized for different functional activities and situations. Initial results of research show that LSVT BIG training leads to:
- faster walking with bigger steps
- better balance
- increased trunk rotation
- improved quality of life
How is LSVT different from usual physiotherapy for PD?
Traditional physiotherapy for Parkinson’s generally aims to improve flexibility, strength or balance to help actions like getting up from a chair, turning over in bed, or walking. This traditional approach breaks down each action but requires patients to remember multiple instructions for each movement goal. In LSVT, patients simply focus on one goal, to think BIG!
How does the program work?
LSVT BIG is delivered by a specially trained physiotherapist over 16 therapy sessions (four sessions a week for four weeks). Participants are encouraged to perform a variety of BIG movements with BIG effort in a series of specifically designed exercises. The focus on one therapy goal (BIGNESS) makes it is easier for patients to participate in this intensive program.
