Study Notes
Treatment Focus and Approaches
- Treatment for Childhood Apraxia of Speech (CAS) emphasizes movement rather than sound.
- Initial therapy includes maximum clinician support using visual, tactile, and auditory cues, which are gradually faded.
- The objective is to enhance movement accuracy, employing various motor learning principles in therapy.
Principles of Motor Learning (PML)
- Definitions: Motor Learning involves acquiring skills through experience and practice, influenced by multiple factors.
- Motor Performance vs. Motor Learning: The former pertains to execution during training; the latter deals with execution at another time (generalization).
- Key precursors to motor learning include motivation, attention, and pre-practice preparation.
- Important aspects for CAS include rate and prosody of speech.
PML: Practice Conditions
- Practice Amount: No systematic evidence favoring small or large amounts of practice.
- Practice Distribution: Undefined effects of massed versus distributed practice.
- Practice Variability: Limited evidence supporting variable practice benefits in unimpaired speech learning, no evidence for motor speech disorders (MSD).
- Practice Schedule: Little evidence for random practice effectiveness compared to blocked practice for untreated speech.
- Attentional Focus: No significant evidence supporting internal over external focus.
- Target Complexity: Limited evidence exists for targeting complex items for Apraxia treatment.
PML: Feedback Conditions
- Feedback Type: No systematic evidence distinguishing between Knowledge of Performance (KP) and Knowledge of Results (KR).
- Feedback Frequency: Some evidence suggests that reduced feedback frequency may be beneficial for AOS treatments.
- Feedback Timing: Delayed feedback could be advantageous in treating AOS and hypokinetic dysarthria.
Treatment Approaches/Methods
- Integral Stimulation and DTTC (Dynamic Temporal and Tactile Cueing).
- PROMPT (Prompts for Restructuring Oral Muscular Phonetic Targets).
- Nuffield Centre Dyspraxia Programme (NDP3).
- Rapid Syllable Transition Treatment (ReST).
- Melodic Intonation Therapy (MIT).
- Use of augmentative devices for communication enhancement.
- Generic approaches founded on PML principles.
- Stimulability Training Program (STP) and modified core vocabulary training (mCVT).
Integral Stimulation
- Articulation therapy focusing on imitation, auditory, and visual models, created by Robert Milisen in 1954.
- Emphasizes listening and visual attention in processing utterances.
- Utilizes prosodic cue methods like Melodic Intonation Therapy to enhance sentence structure and stress.
Dynamic Temporal and Tactile Cueing (DTTC)
- Designed for non-verbal children with severe CAS, building upon Integral Stimulation principles.
- Invites gradual independence from cues, promoting self-assembly of motor plans.
- Establishes foundational skills such as visual attention and imitation through parent involvement.
Methodological Challenges
- Lack of standard CAS definitions and differential diagnosis challenges.
- Significant symptom variability and social control issues in real clinical settings.
- Limited support for large-scale studies.
Treatment Planning Considerations
- Requires careful planning by clinicians and families, with understanding of multiple treatment methods and overlap.
- Clinicians must apply motor learning principles to structure treatment effectively.
- Caution is necessary when using insights from nonspeech motor learning literature for speech treatments.
Evidence and Research Gaps
- Studies indicate the quality of practice frequency significantly influences treatment outcomes.
- Mixed findings on high vs. low feedback frequency effectiveness for CAS treatment.
- Variability in practice schedule (blocked vs. random) remains inconclusive in outcomes for children with CAS.
- Augmentative Communication devices have shown potential benefits, albeit with limited support from case studies.
Childhood Apraxia of Speech (CAS)
- CAS is a neurological speech sound disorder in children, affecting speech movement precision without neuromuscular deficits.
- Causes may include known neurological impairments, complex neurobehavioral disorders, or idiopathic origins.
- Core issues lie in planning and programming speech movement sequences, resulting in errors in sound production and prosody.
Key Features of CAS
- Inconsistent error production for consonants and vowels across repeated attempts.
- Lengthened coarticulatory transitions and impaired sound sequencing.
- Inappropriate prosody, affecting rhythm and intonation.
Treatment Evidence
- There is no gold standard treatment for CAS due to insufficient controlled studies.
- Calls for more rigorous studies to assess treatment efficacy across the entire CAS population.
General Treatment Principles
- Treatment aims to enhance speech motor planning capabilities, focusing on movement rather than sound production.
- Initially, therapists provide high levels of support through visual, tactile, and auditory cues, which are gradually reduced.
- Approaches emphasize movement accuracy, aligned with motor learning principles.
Principles of Motor Learning (PML)
- Motor learning involves acquiring the capacity for skilled actions through practice and experience.
- Factors affecting motor learning include motivation, attention, practice conditions, and feedback.
- Key considerations for CAS treatment involve rate and prosody of production along with feedback conditions.
Feedback and Practice Conditions
- Evidence regarding practice amounts (small vs. large), distribution (massed vs. distributed), and variability (constant vs. variable) is limited.
- Feedback types (knowledge of performance vs. results) and frequencies (high vs. low) show mixed evidence regarding their efficacy.
Treatment Approaches
- Integral Stimulation and Dynamic Temporal and Tactile Cueing (DTTC) are key methods used in therapy.
- Other approaches include Prompts for Restructuring Oral Muscular Phonetic Targets (PROMPT), Nuffield Centre Dyspraxia Programme (NDP3), and Melodic Intonation Therapy (MIT).
Integral Stimulation
- Developed by Robert Milisen, focuses on imitation using auditory and visual models to promote articulation.
- Encourages functional communication by emphasizing prosodic cues early in treatment.
Dynamic Temporal and Tactile Cueing (DTTC)
- Modified version of Integral Stimulation for children with severe CAS, developed by Edythe Strand.
- Allows for gradual responsibility transfer to the child in speech motor planning through structured steps.
Evidence for Treatment Efficacy
- Various studies indicate a positive impact of treatments like Integral Stimulation and DTTC on articulation and verbal communication.
- Combined approaches, like Stimulability Training Program (STP) with modified core vocabulary training, show promise for expanding phonetic capabilities.
Barriers to Research Evidence
- Issues include inconsistent definitions of CAS, diagnostic challenges, symptom heterogeneity, and variability over time.
- Difficulties in experimental control and lack of support for large-scale studies hinder evidence generation.
Conclusions
- Effective treatment planning entails clinician-family collaboration, knowledge of different approaches, and an understanding of motor learning principles.
- Caution is necessary when applying motor learning insights from nonspeech contexts to CAS treatment.
