Understanding LSVT Certification

LSVT certification refers to the specialized training and certification in the Lee Silverman Voice Treatment (LSVT) protocols. The LSVT protocols encompass LSVT LOUD and LSVT BIG, developed to assist individuals with Parkinson’s disease and other neurological conditions.

What Does LSVT Stand For?

LSVT, an acronym for the Lee Silverman Voice Treatment, represents an innovative therapy to address speech-related complications tied to Parkinson’s disease (PD). At the core of LSVT, specifically LSVT LOUD, is the goal to enhance vocal strength and clarity.

This specialized treatment method emphasizes the augmentation of an individual’s vocal intensity. The process endeavors to counterbalance the soft or muted speech often seen in those grappling with Parkinson’s disease, enabling them to reclaim greater communication efficacy.


A crucial aspect of LSVT LOUD implementation is the intensive treatment. An LSVT-certified speech therapist provides sixteen treatment sessions. These hour-long sessions are typically divided over four weeks. This concentrated structure stimulates voice and speech improvements and maintains these enhancements over time.

Does Research Back the LSVT?

The Lee Silverman Voice Technique (LSVT) has a significant body of scientific research endorsing it, dating back to 1989. This multi-decade emphasis on research validates the efficacy and compelling results of LSVT in Parkinson’s Disease therapy.

Research that Substantiates LSVT

A robust body of research supports the beneficial impact of LSVT on Parkinson’s Disease patients. A 2015 study indicated that severe physical therapy rehabilitation during the early stages of the disease slowed the disease’s progression and enhanced motor performance (Frazzitta et al., 2015). The study also discovered the adverse effects of sedentary lifestyles, linking them to increased balance and walking impairments and accelerated disease progression.


In 2013, research on treadmill exercises uncovered that physical exercise boosted the number of brain receptors responsive to dopamine, leading to heightened motor and postural control (Fischer et al., 2013). This finding fuels the concept of neuroplasticity, the brain’s inherent ability to repair and adapt following injury or damage. Interestingly, the study found that the larger the movement amplitudes (as seen in walking compared to seated exercise), the higher the number of dopamine receptors.


In a ground-breaking revelation in 2010, the application of the LSVT Loud protocol (the pioneer speech therapy program behind LSVT Big), researchers noticed visible changes in functional MRI scans. The scans revealed increased activity in the brain areas responsible for motor and coordination tasks when comparing MRI scans before and after administering the LSVT treatment (Narayana et al., 2010). Notably, no Parkinson’s Disease drugs have exhibited similar changes on an MRI scan.

How is LSVT in Practice?

LSVT Big therapy has a singular aim – to magnify the amplitude of all movements through intensive, high-effort exercises and sensory calibration. Here, ‘amplitude’ represents the maximum range of motion performed with peak effort and precision at all times.


In Parkinson’s Disease, patients often have a distorted perception of their movements due to the brain inappropriately identifying their reduced and weak movements as “normal.” For instance, a patient’s brain may assert that small shuffle steps are just “normal” strides. The LSVT Big therapy works to correct this, teaching patients to scale up their movements. This way, what they initially perceived as significant became their everyday movements.


The wealth of research supporting the LSVT protocol underscores its significant potential and success in managing Parkinson’s Disease, demonstrating its effectiveness, high-impact results, and practical application among patients.

What Does LSVT Stand for in Physical Therapy?

Parkinson’s Disease is a progressive neurological condition characterized by the deterioration of nerve cells in the brain governing body movements. It often leads to symptomatic physical impairment and can considerably impact a person’s mobility and day-to-day life.

The LSVT approach has been instrumental in inspiring encouraging results in patients with 


Parkinson’s Disease. Utilizing specific techniques to magnify body perceptions aids those afflicted with the condition to tackle their common tendency of underestimating physical movements, thus enabling them to regain a more normalized body movement and improved quality of life.

What is LSVT for Parkinson’s?

LSVT is a therapeutic approach designed to assist individuals with Parkinson’s Disease. This evidence-based treatment has been proven to address the common speech and movement difficulties experienced by Parkinson’s patients.

LSVT comprises two distinct programs:


  • LSVT LOUD: This program enhances speech by improving vocal loudness and clarity. It encourages individuals to “Think LOUD!” prompting them to recalibrate their perception of vocal loudness for clearer communication.

  • LSVT BIG: This treatment entails exaggerating physical movements, such as high steps and arm swings, to help increase movement amplitude. LSVT BIG is based on proprioceptive recalibration to improve bradykinesia (slowness of movement) and motor symptoms.

These therapy programs are offered by certified clinicians who have completed special training and passed relevant certification exams. By undergoing LSVT treatment, individuals living with Parkinson’s Disease can experience significant improvements in speech, balance, walking, and general movement patterns.

Understanding LSVT and Its Role in Parkinson’s Disease

Parkinson’s Disease is a neurodegenerative disorder that gradually impairs patients’ motor abilities, such as walking and talking, and their capacity to complete daily living tasks. The Lee Silverman Voice Technique (LSVT), an empirically validated therapy, addresses these challenges. Through LSVT, patients learn to amplify their movements and voices, enabling them to combat the debilitating effects of Parkinson’s Disease.

Helping Patients Navigate Parkinson’s Disease

Parkinson’s Disease profoundly impacts the daily lives of those it affects. Combining physical and occupational therapy with specialized programs like LSVT LOUD and LSVT BIG can significantly assist patients. These therapies, along with general conditioning exercises, functional training, and gait and balance training, equip patients to manage their symptoms and enhance their life quality. Therapists also provide strategies to tackle daily tasks, such as getting in and out of bed or the shower, more safely and independently.


LSVT therapy is an evidence-based approach that shows promising results in treating Parkinson’s Disease. These treatment programs have demonstrated clinical effectiveness in enhancing patients’ balance, movements, walking abilities, and speech patterns. They involve targeted, repetitive exercises that leverage the brain’s plasticity—its ability to form new neural connections—to foster motor skills and language reminiscence, enhancing patients’ real-world capabilities.

The Varying Symptoms of Parkinson’s Disease

Although Parkinson’s Disease manifests differently in each individual, a few common symptoms include:

  • Tremors

  • Stiffness in limbs and trunk

  • Bradykinesia, or slowed movements

  • Impaired balance or coordination

These symptoms progressively intensify, making everyday tasks—like getting out of a chair, dressing, walking, talking, and swallowing—increasingly challenging.

Differentiating LSVT Big and LSVT Loud Therapies

LSVT therapy offers two distinct treatment approaches—LSVT Big and LSVT Loud. LSVT Big targets patients’ motor functions, whereas LSVT Loud focuses on stimulating the vocal muscles to enhance speech volume.


LSVT LOUD focuses on improving voice and swallowing function from within, helping those with Parkinson’s to recalibrate their vocal perceptions. This recalibration means they can better gauge their volume levels when speaking, resulting in sustained speech patterns and volume improvements.


LSVT BIG, on the other hand, trains patients to perform exaggerated movements, enabling them to accomplish small motor tasks—like buttoning a shirt—and maintain balance while walking.

Life After LSVT Treatment

The early adoption of LSVT LOUD speech therapy can significantly benefit patients, with vocal improvements lasting two or more years after an initial month of treatment, provided there is ongoing daily practice.

The LSVT BIG treatment includes at least a month-long daily practice and exercises. Even after this treatment, daily home exercises for 10 to 15 minutes are necessary to sustain improvements.


For patients undergoing LSVT treatments, recommendations include:

  • Tune-Up” Sessions: This is an opportunity for therapists to reassess patients’ progress and provide feedback, helping them maintain initial therapy benefits.

  • Join Community Exercise Groups: Joining such groups is encouraged to foster interactions with individuals who have also completed LSVT.

  • Homework Videos: These resources can help patients practice their home exercises daily.

Ultimately, LSVT treatment represents a lifelong commitment for people living with Parkinson’s Disease, providing a way to manage their symptoms and enhance their quality of life.
