Effectiveness of Ultrasound-Aided Articulation Therapy for Children With Speech Sound Disorders

Communication in Children With or Without Biomedical Conditions: Speech and Language Profile, Related Outcomes and Articulation Treatment With Ultrasound

NCT06831396•The University of Hong Kong

View on ClinicalTrials.gov

Summary

This prospective randomized controlled trial investigates the effect of ultrasound visual biofeedback as an adjunct to articulation therapy in children with speech sound disorders involving lingual targets. The intervention aims to facilitate acquisition of misarticulated sounds by providing real-time visualization of tongue movements. Participants are randomized 1:1 to immediate treatment or wait-list control, with stratification by disorder type, age, and gender where feasible. The wait-list control group continues usual care for 4 weeks before crossing over to receive the same intervention (ethical crossover design).
