How Are Speech Problems Treated?

There are many options to help improve your speech. A speech-language pathologist can help you pick the right approach(es) for you.

Seeking help from a speech-language pathologist

Speech-language pathologists are trained health care professionals who specialize in evaluating and treating people with speech, swallowing, voice, language and memory problems.

Before you contact a speech-language pathologist, talk to your primary care or Parkinson’s doctor for a referral. It is also important to contact your health insurance company to find out what therapy and procedures are eligible for reimbursement, and to find a list of speech-language pathologists covered by your plan. Finally, it is best to visit a speech-language pathologist who has experience treating people with Parkinson’s disease. Call the NPF Helpline at 1-800-4PD-INFO (473-4636) for help locating such a professional.

The Lee Silverman Voice Treatment (LSVT®)

LSVT is the first speech treatment for PD proven to significantly improve speech after one month of treatment.

  • Exercises taught in the LSVT method are easy to learn and typically have an immediate impact on communication.
  • Improvements have been shown to last up to two years following treatment.
  • LSVT methods have also been used with some success in treating speech and voice problems in individuals with atypical Parkinson’s syndromes such as multiple-system atrophy (MSA, formerly known as Shy-Drager syndrome) and progressive supranuclear palsy (PSP). 

LSVT® Guidelines

  • LSVT must be administered 4 days a week for 4 consecutive weeks in order to be effective.
  • On days that you have therapy, you should perform your LSVT exercises one other time during the day; on days that you do not have therapy, you should perform your LSVT exercises two times a day.
  • Once you complete the 4-week LSVT therapy, you should perform your LSVT exercises daily in order to maintain your improved voice.
  • Schedule a 6-month LSVT re-evaluation/follow-up with your LSVT-certified speech pathologist to continually monitor your voice.
  • If available in your area, participate in a speech group whose focus is on THINKING LOUD.
  • Unless otherwise directed by a physician, drink plenty of water.
  • A Digital Sound Level Meter can help you monitor your volume. These meters can be purchased for about $45.00. Place the meter at arm distance to perform the measurement. Normal conversational volume ranges between 68-74dB.

Collagen injections

Collagen injections have been used in the treatment of voice and speech impairment in PD:

  • Contact a recommended Ear, Nose and Throat (ENT) doctor to proceed with this type of treatment.
  • The purpose of collagen injections is to build up vocal folds that do not close completely while talking.
  • The procedure involves injecting collagen directly into the vocal folds.
  • The collagen effect typically lasts for 6 months, then must be re-injected.
  • Some patients have reported improvement in their voice from this procedure.

Assistive Communication Devices

  • When fatigue or other illness makes it difficult to use your normal voice you may find an assistive communication device helpful.
  • A personal amplification device is the device most often used by people with PD.
  • Other communication devices range from hand-made communication boards to sophisticated computerized equipment.
  • A speech-language pathologist can recommend an appropriate device.
  • Speech Easy is an FDA-approved feedback device used for stuttering. It is a small electronic device worn on the ear (similar to a hearing aid). Certain people with Parkinson’s who are having difficulty with their voice and also with verbal fluency and stuttering have benefited from use of this device.
