LSVT (Lee Silverman Voice Treatment)

LSVT clinics

LSVT (Lee Silverman Voice Treatment) is an evidence-based treatment for people with Parkinson’s Disease (PD). LSVT directly treats the volume of an individual’s voice and has been shown to have benefit not only for vocal loudness but also for speech precision and improvement of the swallowing musculature. Although the evidence is strongest for people with PD, investigations are underway in the use of LSVT for people whose speech and voice difficulties are related to cerebral palsy, traumatic brain injury and other neurologically-based disorders.

An LSVT program involves a screening appointment and 16 one hour sessions scheduled at four sessions per week for 4 weeks. This intensity of treatment is an integral part of the LSVT program;  no other treatment schedule can be called “LSVT”. Evidence of LSVT's treatment efficacy is based on this intensity of treatment.  If, however, after the screening appointment, you and your therapist decide that the intensity of LSVT is beyond your energy level, we may recommend instead a “vocal intensity treatment program” that can be organized on a different schedule.

The people who are most likely to benefit from LSVT include those who:

  • Have been diagnosed with “idiopathic” (or “typical”) Parkinson’s Disease or another neurological impairment resulting in decreased loudness of speech, imprecise speech and/or swallowing difficulties.  Please note that the strongest evidence exists for those with idiopathic Parkinson’s Disease.
  • Have the stamina, energy and motivation to go through the training.  LSVT is hard work!
  • Have the ability to produce a voice, even if quiet
  • Are able to remember, and to comply with, the practice activities that will be prescribe
  • Have the time to attend 16 sessions, scheduled at four sessions per week for four weeks
  • Have a likely potential to benefit from LSVT, as viewed by the screening SLP
  • Please note:  As with all speech and voice therapy, no guarantee of outcome is provided nor implied.

To Register

1. Please contact our office to book a screening appointment with a speech-language pathologist.

2. Provide payment (cheque, cash, debit or credit) in the amount of $200 when you book your screening appointment.

3. Prior to the appointment, please forward medical documentation of your diagnosis.  (We do not need a doctor’s referral but note that, during the first appointment, we will be asking you for your consent to contact your doctor.)

At the screening appointment, your speech-language pathologist (SLP) will get some background information from you and will take a number of measurements of your speech and voice.  She will also explain the treatment program to you and possibly do some brief trial treatment to get a better idea of whether or not the treatment is likely to be useful for you.  At the end of the appointment, she will make recommendations, which may include that you enroll in either LSVT or in a vocal intensity training program.  Both programs cost $2320 and include 16 sessions, however LSVT must be scheduled at the intensity of four sessions per week for four weeks, whereas vocal intensity training can be scheduled at a lesser intensity for those who don’t have the stamina for LSVT.  It is also possible that your SLP may recommend only a few sessions of speech therapy, acquisition of an amplification device, referral to other services or may not recommend treatment at all, depending on your needs and symptoms.

You should expect that, during the LSVT treatment, you will need to ensure that you are well rested without too many other commitments.  The treatment itself requires physical exertion and you will likely find it tiring. You will receive a brief written report outlining your progress after completion of the program. The LSVT program is completed after 16 sessions, however follow-up appointments can be arranged on an “as needed” basis for people who wish to refresh their skills.
