Enhancing Clinical Practice Through Research: Tools for School-Based Speech-Language Pathologists
PURPOSE: Speech-language pathologists (SLPs) in the school setting need to efficiently locate, evaluate, and utilize research evidence in their clinical practice. This tutorial provides resources focused on the foundational aspects of evidence-based practice (EBP) and its application for SLPs to implement research into clinical practice. METHOD: This tutorial (a) reviews study design and discusses clinical questions best suited to each; (b) provides key tips for extracting information from main sections of research articles; (c) discusses the use of generative artificial intelligence (AI) as a clinical and research tool, including actionable steps and examples for using AI in EBP; and (d) provides detailed strategies to increase interaction with research beyond reading articles. RESULTS: School-based SLPs can utilize the information and strategies provided to increase their confidence in evaluating research literature, applying information, and incorporating resources from research articles into their clinical practice. CONCLUSIONS: This tutorial equips school-based SLPs with actionable steps and concrete tools to increase ease and efficiency of applying research evidence into clinical practice. It provides guidance on different study designs, practical strategies to review research articles, and a case study demonstrating these strategies as well as discusses the potential use of AI to support clinicians in generating clinical questions and the steps of the EBP process.

Rhotic Acquisition Is More Rapid in Biofeedback Than Motor-Based Treatment for Residual Speech Sound Disorder: Primary Outcome of a Randomized Controlled Trial
PURPOSE: Residual speech sound disorder (RSSD) is a high-prevalence condition that can limit children's academic and social participation, with negative consequences for overall well-being. Previous studies have described visual biofeedback as a promising option for RSSD, but results have been inconclusive due to study design limitations and small sample sizes. METHOD: In a preregistered randomized controlled trial, 108 children aged 9-15 years with RSSD affecting American English /ɹ/ were randomly assigned to receive treatment incorporating visual biofeedback (subdivided into ultrasound and visual-acoustic types) or a comparison condition of motor-based treatment consistent with current best practices in speech therapy. An acoustic measure (the distance between the second and third formants, which is smaller in perceptually accurate /ɹ/) was used to quantify progress in the first three sessions of treatment in participants' assigned condition. The focus on the early stages of treatment was grounded in principles of motor learning: As a type of knowledge of performance feedback, biofeedback is expected to have its greatest impact during initial acquisition of a new speech-motor plan. RESULTS: A linear mixed-effects regression model revealed a statistically significant interaction between treatment type and session: While both groups made progress over time, the rate of progress was significantly faster in the biofeedback condition compared to motor-based treatment. No statistically significant difference was observed between the ultrasound and visual-acoustic types of biofeedback. DISCUSSION: This large-scale randomized controlled trial supports previous small-scale research in finding that biofeedback can help children with RSSD acquire American English /ɹ/. A companion study will compare participants' generalization learning after the end of all treatment. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.29971501.
