Purpose: Although mobile apps are used extensively by speech-language pathologists, evidence for app-based treatments remains limited in quantity and quality. This study investigated the efficacy of app-based visual-acoustic biofeedback relative to nonbiofeedback treatment using a single-case randomization design. Because of COVID-19, all…

Purpose: A variety of pediatric clinical populations have difficulty with the correct use of pronouns. The available clinical literature labels these errors in inconsistent terms leading to great variation in how treatment objectives are worded. The purpose of this tutorial is to encourage a shift in pronoun assessment and treatment planning…

Purpose: Cleft palate is one of the most common birth defects in the United States. Most of these children receive speech therapy by preschool and school-based clinicians. The purpose of this article is to provide a comprehensive tutorial for speech-language pathology assistants (SLPAs) regarding treatment techniques and principles for children…

This survey addressed a twofold need: first, research into speech sound productions in children with visual impairments and, second, evidence upon which speech-language pathologists might base interventions for children with visual impairments. Fifteen speech-language pathologists responded to a survey about speech sound productions in caseload…

Background: Children with speech sound disorders (SSD) form a heterogeneous group who differ in terms of the severity of their condition, underlying cause, speech errors, involvement of other aspects of the linguistic system and treatment response. To date there is no universal and agreed-upon classification system. Instead, a number of…

The goal of this research programme was to evaluate the role of word lexicality in effecting phonological change in children's sound systems. Four children with functional speech sound disorders (SSDs) were enrolled in an across-subjects multiple baseline single-subject design; two were treated using high-frequency real words (RWs) and two were…

Patients with lesions of the left hemisphere often suffer from oral-facial apraxia, apraxia of speech, and aphasia. In these patients, visual features often play a critical role in speech and language therapy, when pictured lip shapes or the therapist's visible mouth movements are used to facilitate speech production and articulation. This demands…

Jaw movement patterns were examined longitudinally in a 3-year-old male with childhood apraxia of speech (CAS) and compared with a typically developing control group. The child with CAS was followed for 8 months, until he began accurately and consistently producing the bilabial phonemes /p/, /b/, and /m/. A movement tracking system was used to…

Linguistic theory has made important contributions to the clinical assessment and treatment of children with functional phonological disorders. In this article, Optimality Theory (OT) is introduced as a new linguistic model of grammar. Basic assumptions of the model are described and extended to clinical assessment and treatment. The aim is (1) to…

Changes in consonant and syllable-level error patterns of three children diagnosed with childhood apraxia of speech (CAS) were investigated in a 3-year longitudinal study. Spontaneous speech samples were analyzed to assess the accuracy of consonants and syllables. Consonant accuracy was low overall, with most frequent errors on middle- and…
