In a sample of 46 children aged 4-7 years with Autism Spectrum Disorder (ASD) and intelligible speech, there was no statistical support for the hypothesis of concomitant Childhood Apraxia of Speech (CAS). Perceptual and acoustic measures of participants' speech, prosody, and voice were compared with data from 40 typically-developing children, 13 preschool children with Speech Delay, and 15 part...

PURPOSE Prompts for Restructuring Oral Muscular Phonetic Targets (PROMPT; Hayden, 2004; Hayden, Eigen, Walker, & Olsen, 2010)-a treatment approach for the improvement of speech sound disorders in children-uses tactile-kinesthetic- proprioceptive (TKP) cues to support and shape movements of the oral articulators. No research to date has systematically examined the efficacy of PROMPT for children...

Purpose The purpose of this 2nd article in this supplement is to report validity support findings for the Pause Marker (PM), a proposed single-sign diagnostic marker of childhood apraxia of speech (CAS). Method PM scores and additional perceptual and acoustic measures were obtained from 296 participants in cohorts with idiopathic and neurogenetic CAS, adult-onset apraxia of speech and primary...

PURPOSE Childhood apraxia of speech (CAS) has been associated with a wide variety of diagnostic descriptions and has been shown to involve different symptoms during successive stages of development. In the present study, the authors attempted to associate the symptoms of CAS in a particular developmental stage with particular information-processing deficits by using computational modeling with ...

This study describes change in functional performance and self-perception after participation in combined training with physical practice followed by mental practice. The patient was a 44-yr-old white man who experienced a single left ischemic stroke 7 mo before enrollment in the study. He engaged in physical and mental practice of two functional tasks: (1) reaching for and grasping a cup and (...

Purpose Three previous articles provided rationale, methods, and several forms of validity support for a diagnostic marker of childhood apraxia of speech (CAS), termed the pause marker (PM). Goals of the present article were to assess the validity and stability of the PM Index (PMI) to scale CAS severity. Method PM scores and speech, prosody, and voice precision-stability data were obtained f...

Ideomotor limb apraxia, a disorder of goal-directed movement, has been attributed to lesions in the frontal and parietal lobes, but the role of subcortical structures is less certain. In order to determine its prevalence in a disorder affecting the basal ganglia and corticostriatal connections, we examined imitation of hand gestures in Huntington's disease (HD) patients. We also assessed the re...

OBJECTIVE To assess the effectiveness of a rehabilitative training program for patients with limb apraxia. DESIGN Randomized, controlled trial. SETTING Neurologic rehabilitation unit of a university hospital. PATIENTS Thirteen patients with acquired brain injury and limb apraxia (lasting more than 2 months) as a result of lesions involving the left cerebral hemisphere. Patients were assig...

The purpose of the study was to ex10amine voice onset time (VOT) and its variability in children with childhood apraxia of speech (CAS) compared to typically developing children. Twelve children with CAS aged 912 years old and 20 children who were age-matched participated in the study. This study measured VOT and variabilities of VOT during the production of /p' a/, /t' a/, /k' a/. For variabil...

INTRODUCTION In the present study, we examined the influence of a home-based, DVD-delivered exercise intervention on daily sedentary time and breaks in sedentary time in older adults. METHODS Between 2010 and 2012, older adults (i.e., aged 65 or older) residing in Illinois (N = 307) were randomized into a 6-month home-based, DVD-delivered exercise program (i.e., FlexToBa; FTB) or a waitlist c...
