LSVT LOUD®: Speech Therapy for Parkinson’s Disease and Similar Conditions
LSVT LOUD is an effective speech treatment for people with Parkinson's disease (PD) and other neurological conditions. Named for Mrs. Lee Silverman (Lee Silverman Voice Treatment), a woman living with PD, it was developed by Dr. Lorraine Ramig and has been scientifically studied for over 25 years with support from the National Institute for Deafness and other Communication Disorders within the National Institutes of Health (NIH) and other funding organizations. LSVT LOUD trains people with PD to use their voice at a more normal loudness level while speaking at home, work, or in the community. Key to the treatment is helping people "recalibrate" their perceptions so they know how loud or soft they sound to other people and can feel comfortable using a stronger voice at a normal loudness level.
The standard LSVT LOUD treatment program spans four weeks of individual clinical sessions (four times per week) plus daily homework and carryover exercises. Once that initial treatment is over, you'll continue to practice at least once a day for 10–15 minutes.
Laryngeal Exam Prior to LSVT LOUD
Because many factors can cause changes in perceptual voice quality, an exam of the vocal folds by an ear, nose and throat doctor (ENT) is required before LSVT LOUD treatment. This allows the physician to identify any co-occurring causes or contra-indications (e.g. laryngeal masses, gastric reflux, vocal fold paralysis) that may affect therapy planning and outcomes. These conditions may need to be managed prior to the start of LSVT LOUD.
We recommend that all people with PD be referred for speech, physical and occupational therapy evaluations as soon as possible upon diagnosis, as PD affects both the speech and limb motor systems.
The evaluating therapist can establish baseline performance data, determine the need for treatment and help the person with PD choose the best treatment for his or her symptoms.
Symptoms may be subtle at first, and people often fail to notice changes or deny any concerns, but we know that by diagnosis, the neuropathology already is anything but “early.” Speech, physical and occupational therapists can “unmask” subtle and hidden deficits and educate people with PD on the best time to start therapy.
That said, it’s never too late for evaluation and treatment. People in later stages of PD and with atypical parkinsonisms can gain benefits from treatment.
LSVT Certified Clinicians can conduct trial therapy to determine treatment potential for later-stage patients. Further, treatment exercises can be adapted to accommodate for comorbidities or cognitive impairments that may be present.
There are times your referrals may be for speech, physical and occupational therapy in general – allowing the evaluating therapist and patient to determine the best course of treatment. In other cases, you may be referring specifically for LSVT treatments. If so, a few considerations are listed below.
LSVT programs are evidence-based speech, physical or occupational therapies. LSVT stands for Lee Silverman Voice Treatment. Named for Mrs. Lee Silverman, a woman living with Parkinson’s disease (PD), it was developed by Dr. Lorraine Ramig and has been scientifically studied for over 25 years with support from the National Institute for Deafness and other Communication Disorders within the National Institutes of Health (NIH) and other funding organizations.
Today there are two distinct LSVT therapy programs: LSVT LOUD speech therapy improves communication in daily living; and LSVT BIG physical or occupational therapy improves mobility and movement used in everyday function.
These are not general exercise programs. Instead, they are research-based treatment protocols designed specifically to address the motor, sensory and non-motor symptoms that many people with PD face. LSVT LOUD and LSVT BIG treatments can only be given by specially trained LSVT Certified Clinicians. With their guidance, people with PD will learn to translate skills built during treatment into better everyday communication, function and movement.
Research on LSVT LOUD has documented that people with PD show improvements in loudness and intonation of their speech, as well as clarity of speech, facial expressions, and some preliminary data on swallowing. The research on LSVT BIG is newer, and not as comprehensive as for LSVT LOUD, but it is growing. Studies have shown people with PD improved walking, balance, and activities such as rolling in bed.
People often see the best results when they begin LSVT treatments before noticing significant problems, but it's never too late to start! Treatments are customized to each person's specific needs and goals, so regardless of the stage or severity of your condition, LSVT LOUD and LSVT BIG can produce significant improvements, even if a person is already facing difficulties.
That said, we’ve found that treatment is most effective for people in early or middle stages of their conditions. Keeping one’s voice and movements alive and strong when first diagnosed is much easier than later restoring speech and movement after changes have become more noticeable.
Ask your doctor about referrals to speech, physical and occupational therapies:
Check with your insurance provider to learn what therapy benefits your insurance plan offers. LSVT BIG and LSVT LOUD are billed in the same way as other speech, physical and occupational therapies.
Your LSVT LOUD or LSVT BIG clinician will also be able to give you resources to help with the reimbursement process if needed.
You may be wondering why any licensed speech, physical or occupational therapist cannot deliver LSVT LOUD or LSVT BIG treatment without LSVT certification. Requiring therapists who want to provide LSVT treatments to first complete training and certification ensures that your LSVT treatments will be given correctly and consistent with what research has shown to be most effective.
There are a few helpful hints and considerations that may be useful to you and your family or care team in preparation for LSVT LOUD or LSVT BIG treatment. These are not requirements and may not apply to all people with PD, but we find they can be useful tips. Of course your individual LSVT Certified Clinician will provide you with the most tailored recommendations for your individual needs and situation.
It’s helpful to understand what people with PD experience as well as the theories and science behind LSVT treatments. Here are three easy ways to learn more:
It’s also helpful to understand the non-motor symptoms of PD. Parkinson’s effects on the brain can cause depression, anxiety, apathy and lost interest in things people used to enjoy.
This can seem like sluggishness or other “moods,” but nothing could be further from the truth. That vibrant person you knew is still inside but hidden by a masked face and blunted by these common non-motor symptoms.
The good news is that encouragement from you can help greatly! You’ll discover that after four weeks of intensive LSVT LOUD and/or LSVT BIG treatment, your loved one with PD may be more active, more social, more confident and more empowered to re-engage life!
Because of how the disease affects perception, many people with PD truly don’t realize that their voices are too soft, their posture stooped or leaning to one side, or their movements uncommonly small or slow.
Even once made aware of these issues, it might be difficult for them to make the effort to speak more loudly, sit up straighter, or use larger and faster movements. It also might be difficult for them to remember to make those adjustments.
LSVT LOUD and LSVT BIG include intensive training in “sensory re-calibration” to A) help people recognize their differences in perception, B) learn to make the effort to correct them, and C) gain the confidence to apply that effort in daily life outside of therapy.
Achieving those results is not always easy, but years of research and clinical practice have taught us that not only is sensory re-calibration possible, it’s critical for lasting, meaningful improvements.
Persons with advanced PD or other cognitive changes may need reminders to do the daily home exercises that are vital to successful treatment. They may even benefit from your coaching!
The LSVT Clinician may provide you with some education to help you be the best coach possible. You can also practice LSVT exercises yourself or with the person you’re supporting using our Homework Helper videos!
Please note, however, that if you’re unsure about your ability to perform any exercises safely, it’s important that you first consult the LSVT Clinician providing treatment.
Sometimes therapists want their patients to work without assistance to help them gain confidence and independence using their louder voice and bigger movements in daily living.
If this comes up, please don’t feel you’re being “dismissed” or that your desire to help isn’t appreciated! Support is always appreciated. It’s simply a matter of the therapist doing what he or she believes is needed to best help and fully empower the person with PD.
People with PD do best with reminder cues that are very short and to the point. For people who have received LSVT LOUD treatment, a quick, “Think LOUD” reminder is helpful from time to time.
For LSVT BIG, the cue is “Think BIG” or just “BIG!” You can also pair “BIG” with other words, as in “BIG posture,” “BIG Steps,” and so on. The LSVT BIG therapist will know which movements you may need to cue more often in daily life.
The standard LSVT LOUD and LSVT BIG treatment programs each span four weeks of treatment sessions (four times per week) plus daily homework and carryover exercises.
Once that initial treamtent is over, you'll continue to practice at least once a day for 10–15 minutes to help maintain the gains you worked hard to achieve. It’s important to know that LSVT helps you on a continued basis in this journey of PD.
