Getting BIG in the Community

The Lee-Silverman Voice Training (LSVT) BIG training program is an intensive training program that focuses on large amplitude movements, multiple repetitions, high intensity, and increasing complexity as an individual progresses through the program. The program is typically delivered 4 consecutive times per week for 4 consecutive weeks with the end goal to improve the amplitude of movement and carryover into daily function.

Current evidence shows the benefit of the LSVT BIG on the motor and nonmotor symptoms of Parkinson’s1, but there is a lack of evidence on the use of the LSVT BIG for other conditions such as Down Syndrome.

An established exercise program (LVST BIG) on measures of physical function and quality of life in adults with Parkinson’s and Down Syndrome will contribute to the field's knowledge of evidence-based intervention and treatment of mobility and function deficits and quality of life in understudied populations.


The purpose of this study is to identify benefits of the LSVT BIG training program on the symptoms of Down syndrome and Parkinson’s Disease.


You may be eligible for this study if you are over 18 and have been diagnosed with Down syndrome or Parkinson’s disease.

Benefits to Participants

Direct benefits to participants from investigating include:

  • Positive health benefits of regular exercise
  • Learning new strategies to enhance individual mobility
  • Psychological and physiological benefits of social activity and participation
  • Development of free individualized and condition specific exercise program not otherwise available in the community
