ABSTRACT
PURPOSE: This proof-of-concept study examined the effectiveness of an ultrasound visual biofeedback (UVB) training within the Participatory Adult Teaching Strategy framework for instructing speech-language pathologists (SLPs) on the assessment of sonographic tongue configuration for remediation of speech sound errors. METHOD: This research followed a multiple-baseline, multiple-probe single-case research methodology replicated across behaviors for data collection and analysis. Two school-based SPLs with no previous knowledge or experience with UVB were recruited. RESULTS: Visual analysis of data and effect size calculations using the percentage of nonoverlapping data indicated that training was highly effective in teaching SLPs skills for the assessment of sonographic tongue configuration and how to promote changes in tongue configuration for the remediation of speech sound errors. CONCLUSIONS: This study addressed the current gap in the literature regarding the lack of empirical evidence of UVB training for SLPs. Our findings support the exploration of evidence-based teaching strategies to train SLPs in the use of UVB for assessment of tongue configuration and remediation of speech sound errors. This can be of interest to academic programs and organizers of training opportunities through continued education units.
