Purpose: This study introduces an integrated multimodal intervention (IMI) and examines its effectiveness for the treatment of persistent and severe speech sound disorders (SSD) in young children. The IMI is an activity-based intervention that focuses simultaneously on increasing the "quantity" of a child's meaningful productions of target words…

This study investigated the effects of a scaffolded-language intervention using cloze procedures, semantically contingent expansions, contrastive word pairs, and direct models on speech abilities in two preschoolers with speech and language impairment speaking African American English. Effects of the lexical and phonological characteristics (i.e.,…

Although many children are referred with difficulties in both their speech and their language, the literature offers relatively little guidance on their therapy. Should clinicians treat these difficulties independently? Or should treatment depend on the potential impact of one domain on the other? This study aimed to investigate the relationship…

Purpose: To compare the relative effects of random vs. blocked practice schedules in treatment for childhood apraxia of speech (CAS). Although there have been repeated suggestions in the literature to use random practice in CAS treatment, no systematic studies exist that have directly compared random with blocked practice in this population.…

Replicated evidence of satisfactory 1- and 2-year post-treatment outcomes has been reported for the "Comprehensive Stuttering Program" (CSP). However, little is known about longer term outcomes of the CSP. Yearly follow-up measures were obtained from 18 participants for 5 consecutive years. At 5-year follow-up, participants were maintaining…

Purpose: To explore the use of noninvasive functional imaging and "virtual" lesion techniques to study the neural mechanisms underlying motor speech disorders in Parkinson's disease. Here, we report the use of positron emission tomography (PET) and transcranial magnetic stimulation (TMS) to explain exacerbated speech impairment following…

Evidence of the positive outcomes of phonological treatment is reviewed, with particular emphasis on treatment procedures that have been deemed effective, the specific effects of these treatment on improving intelligibility, and comparisons between treatments in facilitating improved sound production. The effect of phonological disorders on…
