LSVT Therapy (Lee Silverman Voice Treatment)

Banner Health offers the Lee Silverman Voice Treatment (LSVT), a proven, evidence-based program that helps people with Parkinson’s disease and other neurological disorders improve the voice and mobility needed for daily living. Our LSVT-certified clinicians tailor each treatment plan to a patient’s specific needs, following LSVT protocols to achieve the best possible outcomes.

What is the Lee Silverman Voice Treatment (LSVT)?

LSVT is an evidence-based therapy created in the 1980s by Dr. Lorraine Ramig. It was first introduced as LSVT LOUD, focusing on speech therapy to help patients speak with a louder, clearer voice. In the early 2000s, LSVT BIG was added to address physical and occupational therapy needs, using movement exercises to improve mobility.

Only LSVT-certified health care providers - such as Banner Health’s speech, physical and occupational therapists - can deliver these programs.

Who can benefit from LSVT?

Both LSVT LOUD and LSVT BIG address the common communication and movement challenges of Parkinson’s disease and similar neurological conditions. Starting therapy in the early stages often leads to the best results, helping patients maintain strong voices and steady movement.

How does LSVT work?

People with Parkinson’s or other neurological disorders often speak and move more quietly or with smaller motions than normal. LSVT retrains the body to recognize and use normal volume and movement. Although exercises may feel “too loud” or “too big” at first, patients learn to view these levels as normal and carry them into everyday life.

Therapists customize LSVT for each patient’s disease stage and severity. Patients may receive LSVT LOUD, LSVT BIG or both, depending on their needs.

LSVT LOUD

  • Uses targeted vocal exercises to increase speaking volume.
  • Involves frequent, intense practice to help patients “think loud” and “speak loud.”
  • Helps patients learn to sustain a normal, healthy voice in daily conversations.

LSVT BIG

  • Uses exaggerated, quick movements to help patients “think big” and “move big.”
  • Retrains the brain and body to use normal, full-range motions.
  • Aims to make larger movements automatic, improving safety and ease of movement.

What to expect from LSVT

  1. Program length: Four consecutive weeks
  2. Sessions: Four one-hour, one-on-one visits per week
  3. Home practice: Daily exercises to reinforce gains

During each session, your therapist guides you through exercises - “think loud” to “speak loud” and/or “think big” to “move big” - and uses video recordings to track your progress. Over time, these intensive sessions and daily home practice help patients regain normal voice and movement patterns.
