Effectiveness of Ultrasound-Aided Articulation Therapy for Children With Speech Sound Disorders
Sponsor: The University of Hong Kong
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).

Ultrasound-aided articulation therapy
The intervention under investigation is a motor-phonetic approach to articulation therapy, enhanced with ultrasound visual biofeedback (UVBF). The treatment group will receive the intervention immediately, while the waitlist control group will receive treatment after the initial group completes the study. This design allows for comparative outcome assessments between both groups, ensuring that all participants ultimately receive treatment.
