Lateral bracing occurs when the tongue makes contact against the teeth and palate during articulation of speech sounds. Lateral bracing is critical in providing the lingual stability necessary for accurate articulation. Research suggests that lateral bracing is a consistent and effortful process in the typical production of most speech sounds. However, few interventions propose to improve lateral bracing in clients with speech sound disorders. This study aimed to assess the impact of oromyofunctional therapy on lateral bracing in school-aged children with persistent speech sound errors involving the pre-vocalic /r/ sound.
