Treatment Efficacy for Developmental Motor Speech Disorders

Not Applicable
Completed
Conditions
Randomized Controlled Trial for Speech Disorders in Children
Interventions
Behavioral: PROMPT
Registration Number
NCT02105402
Lead Sponsor
The Prompt Institute
Brief Summary

The purpose of this study is to carry out a high-level treatment efficacy study on children with speech sound disorders with motor speech involvement (SSD-MSI) using a well-controlled Randomized Controlled Trial design.

The intervention of choice is the Prompts for Restructuring Oral Muscular Phonetic Targets (PROMPT) approach, which has been effective in treating motor speech disorders in adults and in children with autism and cerebral palsy.

Detailed Description

The results of this study will allow us to determine if there is a causal relationship between PROMPT treatment and outcome measures and predict how much improvement can be expected from this therapy. This study is being conducted as a part of a multicenter clinical trial in the province of Ontario, Canada with three sites: The John McGivney Children's Centre in Windsor, The ErinoakKids Centre for Treatment and Development in Mississauga, and The Speech and Stuttering Institute in Toronto.

The study integrity will be monitored by an arms-length, external agency, The Applied Health Research Centre (AHRC) at St. Michael's Hospital in Toronto. The study is coordinated by the Department of Speech-Language Pathology at the University of Toronto and funded by the PROMPT Institute in Santa Fe, New Mexico.

Primary Outcome Measures
NameTimeMethod
Change in word-level speech intelligibilityAt baseline and following 10 weeks of intervention or waitlist delay

Word level assessment of speech intelligibility will be carried out using the Children's speech Intelligibility Measure.

Change in speech articulationAt baseline and following 10 weeks of intervention or waitlist delay

Assessment of speech articulation will be carried out using the Diagnostic Evaluation of Articulation and Phonology (DEAP) test.

Change in speech motor controlAt baseline and following 10 weeks of intervention or waitlist delay

Formal assessment of the neuromotor integrity of the motor speech system will be carried out using the verbal motor production assessment for children (VMPAC).

Change in Functional Communication:At baseline and following 10 weeks of intervention or waitlist delay

Focus on the Outcomes of Communication Under Six (FOCUS), is a parent questionnaire that captures preschool children's communication abilities as they participate in real-world situations.

Change in phonological processesAt baseline and following 10 weeks of intervention or waitlist delay

Phonological processes will be assessed using the Diagnostic Evaluation of Articulation and Phonology (DEAP) test.

Change in sentence-level speech intelligibilityAt baseline and following 10 weeks of intervention or waitlist delay

Sentence-level assessment of speech intelligibility will be carried out using the Beginner's Intelligibility Test.

Change in criterion-referenced measure of speech motor control.At baseline and following 10 weeks of intervention or waitlist delay

Criterion-referenced assessment of the motor speech system will be carried out using a set of probe words. The audio-video recordings of the probe words will be analyzed by three qualified and blinded speech language pathologists.
