    Study Notes

    Neuromuscular Status

    • Focus on overall physical and neuromuscular status to develop hypotheses regarding the child's speech motor system.
    • Not intended for medical diagnosis.
    • Indicators of motor involvement include:
      • Clumsy gait.
      • Muscle mass asymmetry.
      • Low tone leading to open mouth posture, droopy eyes, and facial muscle dysfunction.
      • Adventitious movements.
      • Variations in strength and coordination in non-speech movement patterns.
      • Medical reports of pathological reflexes associated with dysarthria.

    Diagnostic Battery

    • Structural-Functional Examination assesses five movement parameters:
      • Range of motion.
      • Speed.
      • Strength.
      • Ability to vary muscular tension.
      • Coordination.

    Motor Speech Examination

    • Involves connected speech samples:

      • Conversation.
      • Picture description.
      • Narrative.

    • Diadochokinesis measures:

      • Alternating Motion Rates (AMR).
      • Sequential Motion Rates (SMR).

    • Hierarchical utterance tasks include:

      • Vowels in isolation (e.g., /i, o, ai/).
      • Consonant-vowel (CV) and vowel-consonant (VC) combinations.
      • Consonant-vowel-consonant (CVC) combinations.
      • Words with matching initial and final sounds (e.g., mom, pop).
      • Words with different initial and final sounds (e.g., pad, cat).
      • Increasing word lengths (e.g., come, computer).
      • Multisyllabic word and phrase repetition.
      • Sentences of increasing length (e.g., I want more milk).

    • Kaufman’s hierarchy may employ various levels of support:

      • Direct imitation.
      • Modeling with visual/auditory cues.
      • Tactile/gestural cues.
      • Phonetic placement cues.

    Sound System Description

    • Developmental processes are common in typical development and most speech disorders.
    • Non-developmental processes are rare and include issues like favorite sound usage and vowel errors.
    • Degraded performance across trials is indicative of further testing for developmental apraxia of speech.
    • Key areas of focus: prosody, verbal sequencing, and articulation.

    • Identifies breakdown levels in speech production to guide treatment.
    • Test administration is straightforward, measuring imitative responses and locating speech system breakdowns.

    Sound System Analysis

    • Consistency across word production should be analyzed in repetitions of spontaneous and imitated tokens.
    • Children without developmental apraxia of speech (DAS) typically improve in trials, while those with DAS often show performance degradation.
