LSVT BIG (Lee Silverman Voice Treatment BIG) is a specialized physical therapy program designed to address the movement impairments caused by Parkinson’s disease. It is an adaptation of the original LSVT LOUD program, which focuses on speech and voice training for PD patients. Recognizing that movement difficulties often accompany vocal impairments, researchers developed LSVT BIG to target motor skills and enhance physical function.

LSVT BIG is an intensive, effective, one-on-one treatment created to help people with Parkinson's disease (PD) and other neurological conditions address walking, balance and other activities of daily living (for example, writing, dressing and getting up from low chairs) or even job-related tasks.

The program emphasizes large, exaggerated movements to counteract the micrographia and hypokinesia (small, slow movements) commonly associated with Parkinson’s. By practicing these big, deliberate movements, patients can recalibrate their motor output and develop a new perception of normal movement.

1. Daily Exercises: These involve repeated practice of specific movements like reaching, stepping, and bending. The exercises are designed to be functional and transferable to everyday activities.
2. Functional Component Tasks: Patients practice actions they struggle with in daily life, such as buttoning a shirt, writing, or getting out of a chair.
3. Hierarchical Tasks: These are more complex activities that are broken down into manageable steps and practiced progressively.
4. High Intensity and High Effort: The program requires patients to push themselves physically and mentally, ensuring optimal results.

1. Improved Movement and Coordination: By focusing on large, purposeful movements, LSVT BIG helps patients combat the slow and small movements caused by Parkinson’s. This translates into better balance, improved gait, and enhanced overall mobility.
2. Increased Independence: With regular practice, patients often find it easier to perform daily tasks like dressing, cooking, and walking. This boosts their confidence and fosters a sense of independence.
3. Enhanced Quality of Life: Parkinson’s can significantly impact mental health, leading to anxiety or depression. The physical improvements from LSVT BIG can reduce feelings of frustration and isolation, promoting a more positive outlook on life.
4. Neuroplasticity: LSVT BIG leverages the brain’s ability to adapt and form new neural connections. By practicing new movement patterns, patients stimulate neuroplasticity, which may help slow the progression of motor symptoms.
5. Early and Long-Term Benefits: Research shows that patients who begin LSVT BIG early in their diagnosis experience greater benefits and may delay the onset of severe motor impairments. Additionally, continued practice of the exercises after completing the program helps maintain gains.
