LSVT stands for Lee Silverman Voice Treatment, which is usually suggested for people suffering from Parkinson disease (PD). These exercise-based behavioral treatments began with a focus on the speech motor system (speech therapy) and was called LSVT LOUD. More recently, the program was extended to include limb motor systems (physical therapy), or LSVT BIG.

LSVT includes a combination of programs that focus on increasing amplitude, sensory recalibration and self-cueing training, says an article published by the National Center For Biotechnology Information. Such treatment is given mainly for Parkinson’s Disease, which is marked by nasal, facial, mood, sleep, urinary and cognitive disturbances. If left without any treatment, patients can gradually lose their ability to walk or talk.

LSVT BIG and LOUD can help with treating neurological disorders. Together, they improve balance and vocal abilities. Here’s a look at how LSVT can help patients live more fulfilling lives.


This is physical therapy that helps in all stages of healing. It includes diagnosis through recovery and rehabilitation. This can prove helpful in pain management, improve mobility, and prevent dangerous falls, say experts at Coastal Home Rehab. LSVT BIG is an effective one-on-one program that can be tailored to the needs of the elderly living at home.

After a few sessions, patients might experience increased trunk rotation and faster walking without high-effort practices. They may also learn how much effort is needed for standard movements. Anyone with mild dyskinesia or idiopathic PD can expect optimal results.


A few of the earliest signs of PD can be observed even before motor problems appear. Among these, voice changes is a significant one, according to an article by Healthline. The LSVT LOUD program can help boost vocal loudness using exercises that can regulate the voice box muscles. Subsequently, it works on the articulatory areas, helping improve impaired swallowing and enhancing the functions of the respiratory laryngeal. These can improve speech to quite an extent.

Do note that the treatment is not aimed at helping people shout or scream. It simply helps you understand that your voice is softer than the standard human sound. The program ensures healthy vocal loudness without any tightness in the chords. This is done by high-intensity and high-frequency exercises. After a few sessions, patients might also see a fair improvement in facial expressions without straining while speaking.

A combination of both programs can have a positive impact on a patient’s life. A trusted rehabilitation center, with skilled nursing and home-based care can help prevent medical complications in the future.
