What is LSVT BIG?
LSVT BIG (Lee Silverman Voice Treatment — BIG) is a certified intensive motor rehabilitation program developed specifically for Parkinson's disease. It focuses on recalibrating the brain's internal sense of movement scale.
Why Parkinson's Patients Move Small
Parkinson's damages the basal ganglia circuits that regulate movement amplitude. Patients genuinely feel they are moving normally when they are actually making tiny, shuffling movements. LSVT BIG corrects this miscalibration.
The 7 Standard Exercises
Maximal daily exercises target limb and trunk movements in all directions. Each exercise is performed at maximum amplitude — as large, as fast, and as loudly as possible — to recalibrate the motor system.
What Research Shows
Clinical trials show LSVT BIG improves walking speed, stride length, arm swing, and quality of life scores significantly more than conventional physiotherapy over the same period.
