Dysarthria

Therapy for slow, slurred or hard-to-understand speech caused by weakness in the speech muscles, often after a stroke or brain injury, or with Parkinson's disease or multiple sclerosis.

What Is Dysarthria?

Dysarthria is a motor speech disorder caused by a weakening of the muscles responsible for producing sound, which limits a person's ability to pronounce words and speak effectively. It's typically the result of a neurological injury of varying severity — stemming from causes like brain trauma, stroke, Parkinson's disease, multiple sclerosis, muscular dystrophy, cerebral palsy, tumors, or Huntington's disease. A reaction to certain prescription medications can also bring on some cases of dysarthria, in which case a patient's physician may recommend changing or stopping that medication.

How Dysarthria Affects Speech and Communication

The classic signs of dysarthria are slow or slurred speech that makes a person difficult to understand, though the specific symptoms vary depending on the underlying cause and the type of dysarthria involved. It's worth scheduling an evaluation if you notice any of the following in yourself or someone close to you, since earlier attention generally means a better chance of improvement.

  • Speech that's very fast and hard to follow
  • Speech that's noticeably slower than usual
  • Slurred speech
  • A strained, nasal, or raspy voice
  • Trouble regulating volume — speaking too loudly or too softly
  • Speech volume that varies unexpectedly
  • Difficulty moving the facial muscles or tongue

Speech Therapy for Dysarthria

The techniques we use depend on exactly how a person's dysarthria is affecting their speech muscles, and treatment is built around the specific qualities of speech involved.

  • Resonance — a person's ability to shape their vocal tract and the resonant spaces speech sounds rely on
  • Articulation — how clearly and successfully someone can produce the sounds and words they intend to
  • Intensity — volume regulation, which conditions like Parkinson's disease can disrupt by affecting the nerve circuits that control it
  • Prosody — the natural emphasis and inflection that convey tone, humor, irony, or other nuance in speech; some patients speak in a flatter, more monotone way as this is affected
  • Phonation — vocal cord quality and control, especially important for anyone who relies heavily on their voice, addressed through retraining and strengthening the vocal cords and surrounding muscles
  • Augmentative and alternative communication (AAC) — auxiliary tools like smartphones, writing, gestures, sign language, or speech-to-text and text-to-speech programs, brought in as needed to support communication

Goals of Speech Therapy for Dysarthria

The overarching goal is always to help a patient restore their ability to speak normally and communicate effectively, though what's achievable varies with the nature and severity of each person's condition. Because no two patients are alike, we take a number of individual factors into account when building a therapy plan.

  • Occupation — different jobs call for different techniques or intensities of practice
  • Hobbies — understanding what a patient enjoys helps shape therapy that supports their quality of life
  • Personal goals — each patient starts with their own targets, and therapy is built around what's realistically achievable for them
  • Social situation — home and family circumstances differ widely, and we look for ways to involve a patient's friends, family, and colleagues to make the process smoother for everyone
  • Day-to-day routine — understanding what a typical day looks like, including any support a patient has, helps shape a plan that fits their actual life

Our Approach to Treatment

With so many individual factors to weigh, effective dysarthria therapy has to be highly personalized. We take pride in offering that kind of individualized care, focused on restoring each patient's quality of life regardless of their age or the circumstances behind their condition.
