Treatment Efficacy for Developmental Motor Speech Disorders
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.
Randomized Controlled Trial for Speech Disorders in Children
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Investigator, Outcomes Assessor)
Primary Purpose: Treatment
|Official Title:||Treatment Efficacy for Developmental Motor Speech Disorders: A PROMPT Randomized Control Trial|
- Change in speech motor control [ Time Frame: At 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 speech articulation [ Time Frame: At 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 word-level speech intelligibility [ Time Frame: At 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 Functional Communication: [ Time Frame: 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 criterion-referenced measure of speech motor control. [ Time Frame: 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.
- Change in phonological processes [ Time Frame: At 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 intelligibility [ Time Frame: At 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.

Experimental: Intervention Group - PROMPT therapy
Prompts for Restructuring Oral Muscular Phonetic Targets (PROMPT)
The PROMPT approach utilizes a motor-speech hierarchy (MSH) to guide speech language pathologists (SLP) in selecting speech movement goals for treatment. PROMPT treatment generally proceeds systematically in a bottom-up fashion starting with the lowest subsystem in the hierarchy where a child has control issues. Furthermore, in the PROMPT approach specific techniques are used to stimulate sensory input that are assumed to facilitate the formation of sensory-motor pathways required for the acquisition and accurate production of speech movement patterns. As the speech motor behaviors are established, the clinician reduces the number of cues and the frequency and immediacy of feedback and practices transfer and generalization activities.
Other Name: PROMPT therapy
No Intervention: Waitlist or Delay Group
Participants in this group are on the waitlist for 10 weeks
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.
