Comprehensive Study Notes on Fluency Disorders: Childhood, Adulthood, Cluttering, and Multicultural Issues

Etiology and Classifications of Fluency Disorders

• Childhood Forms of Stuttering

  • These are the primary forms clinicians deal with, typically starting in childhood.
  • Stuttering usually begins before school age.
  • It is very infrequent for an individual to start stuttering after school age, though it is possible in rare cases.

• Etiological and Symptomological Differences

  • There tend to be distinct differences in etiology, symptomology, and various phenomena between adult-onset and childhood-onset disfluency disorders.
  • Childhood Fluency Disorder: Often associated with unusual breathing patterns (such as clavicular breathing), word-final disfluency (stuttering on the last syllable of a word), language disorders, and cluttering.
  • Adult-Onset Fluency Disorders: Typically categorized as either Neurogenic or Psychogenic.
    • Neurogenic Stuttering: Usually acquired due to a Traumatic Brain Injury (TBI), tumor, or other spontaneous neurological events.
    • Psychogenic Stuttering: Induced by psychological issues or trauma.

Evaluation Procedures for Childhood Fluency

• The Parent Interview

  • This should be conducted first and must be done alone, without the child present.

• Essential Screening and Sampling

  • Hearing Screening: Always mandatory for a fluency evaluation.
  • Speech Samples: Clinicians must obtain $3$ speech samples from different settings.
    • For school-age children, adolescents, or adults: Two running speech samples (conversational) and one reading sample.
    • For preschool children: A home sample is required because they may not yet be in a school setting, and the clinician needs to observe language use in the home environment.

• Secondary Evaluation Components

  • Teacher interview and questionnaires.
  • Parent speech assessment.
  • Self-rating scales: These are described as pivotal for tracking progress moving forward.
  • Language and Articulation Screeners: These are necessary to rule out comorbid issues. For example, individuals with language impairments may demonstrate revisions due to word-finding difficulties.

Symptoms, Secondary Characteristics, and Disfluency Types

• Secondary Characteristics

  • These are physical behaviors that accompany stuttering events. Examples mentioned include:
    • Eye blinking and loss of eye contact.
    • Tapping (finger tapping, toe tapping).
    • Neck tension and facial grimacing.
    • Lip quivering.
    • Avoidance behaviors.
    • Poor or shallow breathing, sometimes leading to visible color changes.
    • Physical jerking of the head or closing eyes until the individual is ready to speak.

• Types of Disfluencies

  • Prolongation.
  • Interjection.
  • Sound repetition.
  • Revision.
  • Word repetition (or forward repetition).

Differential Diagnosis: Language Disorders vs. Stuttering

• Distinguishing the Two Disorders

  • Language Disorder: The individual has difficulty formulating the message (semantic or syntactic formulation). They may use circumlocution (talking around a word because they cannot find it, e.g., describing something as "makes a circle" because they cannot recall the word "round"). They often use phrase repetitions and revisions.
  • Stuttering: The individual knows exactly what they want to say but has difficulty physically getting the message out. Interjections are more common in stuttering than in pure language disorders.

• Differentiating Factors

  • Writing: Language-based disfluencies often show up in an individual’s writing, whereas stuttering usually does not.
  • Emotional State: Individuals with language disorders tend to feel frustrated or upset when they can't find words. Individuals who stutter often feel embarrassed or discouraged.
  • Metaphor for Language Disorder: It is compared to trying to explain complex concepts (like "how the universe is held together") without having the vocabulary, leading to pulling random words like "gravity" or "cosmic energy."

• Concurrent Treatment

  • Stuttering and language disorders can exist together. Treatment should be determined on an individual basis.
  • Advantage of Concurrent Treatment: Progress can be made in both areas simultaneously (broad vs. narrow function), "killing two birds with one stone."
  • Disadvantage of Concurrent Treatment: It can be difficult to select the optimal training context. It can also be overwhelming for families to carry over two different skill sets at home.

Cluttering: Clinical Characteristics and Neurological Basis

• Definition of Cluttering

  • Characterized by a rapid, irregular speech rate where words are pressed together.
  • The speech is often disorganized or disjointed.

• Neurological Basis

  • Research suggests a neurological basis involving hyperactivity and dysregulation of the medial frontal cortex.

• Clinical Features

  • Often involves higher-level language formation and organization difficulties.
  • Usually identified later than stuttering, as it involves complex language skills not as prominent in toddlers.
  • Co-occurrence: Cluttering co-occurs with stuttering more frequently than many clinicians realize.
  • Self-Awareness: Unlike people who stutter (who are highly self-aware), individuals who clutter often have little to no awareness of their disfluency and do not realize others cannot understand them.
  • Speech Characteristics: Precise repetitions, incomplete words/phrases, choppy rhythm, imprecise or slurred articulation, and sound transpositions (which are not typically seen in stuttering).

Cluttering Assessment and Treatment Strategies

• Assessment Steps

  • Comprehensive case history and medical history (checking for asthma, dysarthria, CVI, deafness, or Tourette’s).
  • Observing the client in multiple contexts.
  • Narrative samples (storytelling with a beginning, middle, and end).
  • Cluttering is most likely to occur in informal/unguarded situations.

• Treatment Techniques

  • Reducing Rate: Necessary for increased linguistic control. Use analogies for children, such as a radio at high speed or a derailed fast-moving train.
  • Delayed Auditory Feedback (DAF): Extremely beneficial for clutterers because it forces them to hear their own rapid speech play back to them.
  • Self-Monitoring: Encouraging the client to read listener body language and facial expressions.
  • Coding Text: Preparing reading materials with specific marks for where to pause, stop, or take a breath.
  • Pacing Boards: Using visual or tactile aids (pacing boards, finger tapping) to regulate rhythm.
  • Modulating Articulation: Having the client exaggerate stressed syllables to provide better sensory feedback.
  • Metacognitive Skills: Self-recorded speech analysis is best for clients with metacognitive skills, usually around $3^{rd}$ grade or older.

Neurogenic and Psychogenic Stuttering

• Neurogenic Stuttering

  • An acquired disorder resulting from an impairment of the nervous system (lesion, TBI, or tumor).
  • A confirmed neurological impairment must exist for this diagnosis.
  • Distinct Characteristics: Stuttering occurs across all words of an utterance, not just the initial words. Content and function words are stuttered equally. Secondary behaviors are usually absent. Stuttering persists even on highly automatic tasks (like saying one’s own name).
  • Palilalia: Often associated with neurogenic conditions. It is the repetition of the same word or phrase with diminishing loudness and increasing rate.

• Psychogenic Stuttering

  • Individuals typically have no awareness of the nature of the problem.
  • Often associated with a diagnosis of depression, schizophrenia, neurosis, or psychosis.

Malingering in Fluency Disorders

• Definition: The intentional faking of a disorder for personal gain.
• Characteristics:
  • Rarely seen in children; more common in adults seeking specific benefits.
  • Lacks symptom variability. The individual usually only stutters in the way they believe stuttering sounds (e.g., repeating the same sound pattern constantly).
  • The individual is typically not bothered or depressed by the stuttering behavior.

Multicultural and Bilingual Considerations

• Incidence and Identification

  • Stuttering is identified globally with similar incidence rates across cultures.
  • Clinicians must evaluate bilingual individuals in all languages they speak. If they stutter in one language, they likely stutter in the other.

• Clinical Practice

  • Interpreters: A trained interpreter is preferred over a family member for standardized testing to ensure validity and avoid bias. Family members may understand the client better than the general public.
  • Cultural Sensitivity: Avoid stereotypes. For example, a lawyer from Hong Kong may have more in common with an American architect than a street vendor from their own city.
  • Differential Diagnosis: One must be careful with African American English (AAE), where exaggerated tones or stress patterns might be misinterpreted as prolongations by an unfamiliar judge.

Questions & Discussion

• Q: How do you differentiate between abnormal breathing vs. dysarthria?

• A: During the oral-peripheral mechanism exam (oral MEC), use "sustained ah" tasks. Also, check medical history for existing diagnoses like asthma or TBI.

• Q: How do you know the difference between a tic (Tourette’s) and a stutter?

• A: Tics are involuntary and the individual has no desire to do them. In stuttering, the individual knows exactly what they want to say but has an inability to get it out. Stuttering is often characterized by a loss of control specifically during speech production.

• Interaction: The Guest Name Activity

  • A classroom activity (recorded for TikTok) involved identifying the voices of various students saying "Hey, Doctor Crump."
  • Names mentioned include: Doctor Crump, Gracie, Claire, Sophie, Cassidy, Madison Reed, Madison Bennett, Kayla, Kara, Jackson, Madison Jones, Olivia, Kensey, Mabry, Lori, Abby, Maggie, Allison, Brooke, and Sarah.

• Note on Environment: The session concluded with a brief discussion regarding a wasp and a splinter, and the conclusion of the lecture unit.
