How do you test for dysarthria?


  1. Imaging tests. Imaging tests, such as an MRI or CT scan, create detailed images of your brain, head and neck that may help identify the cause of your speech problem.
  2. Brain and nerve studies.
  3. Blood and urine tests.
  4. Lumbar puncture (spinal tap).
  5. Brain biopsy.
  6. Neuropsychological tests.

What is the assessment of intelligibility of Dysarthric speech?

The Assessment of Intelligibility of Dysarthric Speech (Yorkston & Beukelman, 1984) is one of the most well-known intelligibility tests for dysarthria. The purpose of this test is to obtain an estimate of overall severity. The dysarthric speaker reads 50 one- or two-syllable words, one at a time.

How do you measure intelligibility?

There are two primary approaches to measuring intelligibility: 1) word-identification approaches that involve having an unfamiliar listener orthographically transcribe what they think the child said, and 2) scaled ratings that involve making global judgments about a child’s intelligibility.

How do you calculate intelligibility?

A percent-intelligible score is calculated for each listener by dividing the total number of words identified by the total number of words actually spoken by the child. When multiple judges are used, the child’s overall intelligibility score is the average of the judges’ scores.

How does dysarthria affect language?

Overview. Dysarthria occurs when the muscles you use for speech are weak or you have difficulty controlling them. Dysarthria often causes slurred or slow speech that can be difficult to understand.

How can you tell the difference between dysarthria and aphasia?

Is the Frenchay dysarthria assessment standardized?

One of the most important objective tests for evaluating the articulatory organs is the Frenchay Dysarthria Assessment (FDA). The FDA is a standardized test which relies on a 9-point rating scale applied to a patient.

What is speech intelligibility scale?

The Speech Intelligibility Rating (SIR) Test has been developed for use in clinical comparisons of hearing aid conditions. After listening to a short passage of connected speech, subjects generate a rating proportional to its intelligibility using an equal-appearing interval scale from 0 to 10.

What is considered unintelligible speech?

The term unintelligible refers to speech that is very difficult for others to understand due to factors other than voice volume. The term has no relation to the term intelligence.

How does dysarthria affect communication?

People with dysarthria have trouble making certain sounds or words. Their speech is poorly pronounced (such as slurring), and the rhythm or speed of their speech changes.

What’s the difference between dysarthria and apraxia?

People who live with apraxia have difficulty putting words together in the correct order or ‘reaching’ for the correct word while speaking. Dysarthria occurs when a patient’s muscles do not coordinate together to produce speech.
