LSVT BIG (Lee Silverman Voice Treatment BIG) is a specialized type of physical therapy program designed for individuals with Parkinson's disease. It focuses on improving movement amplitude, strength, and motor coordination through repetitive exercises and functional activities.

LSVT BIG consists of a series of exercises that target specific movement patterns commonly affected by Parkinson's disease, such as walking, balance, reaching, and posture. These exercises are performed with exaggerated amplitude and intensity to help counteract the decreased movement amplitude characteristic of Parkinson's.

The program typically involves one-on-one sessions with a physical therapist specially trained in LSVT BIG techniques. During these sessions, the therapist works closely with the individual to customize the exercises to their specific needs and abilities.

LSVT BIG has been shown to be effective in improving mobility, balance, and overall function in people with Parkinson's disease. It can help individuals maintain or even regain independence in daily activities, enhancing their quality of life.
