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


Sponsor

The University of Hong Kong

Enrollment

60 participants

Start Date

Nov 11, 2023

Study Type

INTERVENTIONAL

Conditions

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).


Eligibility

Min Age: 5 YearsMax Age: 12 Years

Inclusion Criteria7

  • Primary diagnosis of speech sound disorder with errors on lingual target sounds
  • Probe accuracy \<70% on the primary target sound at baseline
  • Cantonese as the first language
  • Hearing thresholds ≤25 dB in at least one ear, with no hearing loss exceeding 50 dB in the other ear
  • No syndromes or obvious dysmorphic features
  • No language disorders associated with biomedical conditions (e.g., cerebral palsy, autism spectrum disorder)
  • No oronasal fistula identified on oral examination or diagnosed velopharyngeal insufficiency

Exclusion Criteria3

  • Presence of syndromes or dysmorphic features
  • Language disorder associated with biomedical conditions (e.g., cerebral palsy, autism spectrum disorder)
  • Hearing thresholds \>25 dB in one ear and \>50 dB in the other ear Planned surgical intervention during the study period

Interventions

BEHAVIORALUltrasound-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.
