Intensive Speech Motor Chaining Treatment for Residual Speech Sound Disorders

Sponsor

Syracuse University

Enrollment

84 participants

Start Date

Oct 26, 2023

Study Type

INTERVENTIONAL

Conditions

Speech Sound Disorder

Summary

The goal of this randomized-controlled trial is to compare distributed treatment schedules and intensive treatment schedules in 84 school-age children with residual speech sound disorders. The main question it aims to answer is: * How does intensive and distributed treatment affect speech sound learning in residual speech sound disorder? Some participants will be treated with a traditional Distributed schedule of 2 sessions per weeks for 8 weeks (16 hours total), whereas others will be treated with an Intensive schedule and will complete 16 hours of treatment in 4 weeks.

Interventions

BEHAVIORALSpeech Motor Chaining

Sessions begin with Pre-practice to elicit target sounds, with verbal cueing and shaping strategies. During Structured Practice, items are practice in blocks of 6 consecutive trials (with systematic increases in difficulty), and our web-based software will manipulate the principles of motor learning, including the stimulus prompt, the participant's production, analysis of the clinician's rating, feedback prompts for the clinician, and the variability present in the practice trial. Randomized Practice will also be guided by the software and includes all linguistic levels that were produced correctly during Structured Practice, with items presented in random order.
