    Study Notes

    Apraxia Specific Assessment Procedures

    • Assess motor planning capabilities through imitation and commands in speech and nonspeech tasks.
    • Measure DDK (Diadochokinetic) rates using standardized tests for systematic evaluation.
    • Indicators of Apraxia include:
      • Variable vowel and diphthong errors.
      • Nasality and NAE (Nasal Air Emission) without CLAP (Clean Auditory Perception), indicating a high likelihood of AOS (Apraxia of Speech).
      • Prosodic problems affecting speech rhythm and intonation.
      • Increased errors in longer utterances compared to single words.
      • Observing groping behaviors during speech attempts.

    Articulation vs. Phonological Disorder Differential Diagnosis

    • Production of multiple phonemes using the same sound (e.g., /t/ for /s/ or /ʃ/) signals phonological disorder due to lack of phonological awareness.
    • Preservation of phonemic contrast across word positions (prevocalic, intervocalic, postvocalic) typically indicates an articulation disorder.
    • Consistent but generalized learning issues suggest an articulation disorder.
    • Emerging or easy context sounds may show good stimulability; articulation techniques are preferred over phonological techniques for isolated sound production.

    Visual Detection Methods

    • Mirror Test: Used solely for NAE assessment; placing a dental mirror under the nose can show clouding, indicating NAE. Test limitations include timing and normal respiration affecting results.
    • Air Paddle: Similar to the mirror test but uses flat paper; applicable only for voiceless, pressure-sensitive consonants. Less sensitive, effective mainly with severe NAE.

    Tactile Detection Techniques

    • Place fingers on the nasal area during speech production; vibrations during oral sounds hint at hypernasality.
    • Not suitable for assessing NAE.

    Nasal Cul De Sac Test

    • Compare sound production with an unoccluded nose and then occluded. Changes indicate potential nasal issues.
    • For hypernasality, vowels should show a difference; no change suggests normal VP (velopharyngeal) movement.
    • For NAE, evaluate pressure-sensitive sounds similarly.
    • Listening tube/Stethoscope/Oronasal listener: Position the device under the nose or on the nasal area for feedback about NAE and hypernasality.
    • Straw Method: Aids in differentiating between NAE and hypernasality; audible airflow denotes NAE, while silence suggests hypernasality.

    Speech Production Analysis

    • Speech Sampling: Represents daily speech use through various stimuli like pictures, word lists, sentences, or conversation; assess phonemes in all positions.
    • Phonetic Inventory: Identify which phonemes the patient can produce correctly in different positions.
    • Nature of Errors: Use SODA (Substitution, Omission, Distortion, Addition) to analyze error types and determine intervention methods.
    • Elicitation Methods: Include reading materials like the Grandfather Passage or Rainbow Passage, conversations, and picture stimuli.
    • Percentage of Correct Consonants (PCC): Measures severity of articulation errors.
      • Mild (85%-100%)
      • Mild/Moderate (65%-85%)
      • Moderate/Severe (50%-65%)
