Intensive treatment has been repeatedly recommended for the of speech deficits in childhood apraxia (CAS). However, differences outcomes as a function intensity have not systematically studied this population.To investigate effects on outcome measures related to articulation, functional communication and intelligibility children with CAS undergoing individual motor intervention.A total 37 (32-54 months age) received 1×/week (lower intensity) or 2×/week (higher 10 weeks. Assessments were...
Observation of limb movements in human subjects resulted increased motor-evoked potential (MEP) amplitude elicited by magnetic stimulation motor cortex the muscles involved that movement, suggesting an observation–execution matching (OEM) system exists humans. We investigated whether OEM is activated speech gestures presented visual and auditory modalities. found observation movement enhanced MEP ampli- tude specifically production observed speech. In contrast, listening to sound did not...
Children with idiopathic apraxia experience difficulties planning the movements necessary for intelligible speech. There is increasing evidence that targeted early interventions, such as Prompts Restructuring Oral Muscular Phonetic Targets (PROMPT), can be effective in treating these disorders. In this study, we investigate possible cortical thickness correlates of speech childhood, and changes associated participation an 8-week block PROMPT therapy. We found children (n = 11), aged 3-6...
Abstract Background Currently, there is limited information on the intervention efficacy for children with speech motor delay (SMD). This randomized control trial (RCT) study examined effectiveness of Prompts Restructuring Oral Muscular Phonetic Targets (PROMPT) to improve outcomes in SMD. We hypothesized that SMD receiving PROMPT would more measured than those waitlisted and home training. Methods Using a two-arm, parallel group, RCT, 49 were allocated either an group ( N = 24) received 45...
Apraxia of speech is a persistent motor disorder that affects intelligibility. Studies on disorders with transcranial Direct Current Stimulation (tDCS) have been mostly directed toward examining post-stroke aphasia. Only few tDCS studies focused apraxia or childhood (CAS), and no study has investigated individuals CAS Trisomy 21 (T21, Down syndrome). This N-of-1 randomized trial examined the effects combined learning task in developmental co-existing T21 (ReBEC RBR-5435x9). The accuracy...
Objective: This study examines the effect of Motor Speech Treatment Protocol (MSTP), a multi-sensory hybrid treatment approach on five children (mean: 3;3 years; S.D. 0;1) with severe to profound speech sound disorders motor difficulties.Methods: A multiple probe design, replicated over participants, was used evaluate effects improving listeners' auditory and visual judgements accuracy.Results: All participants demonstrated significant change between baseline maintenance conditions,...
This study evaluated changes in motor speech control and inter-gestural coordination for children with sound disorders (SSD) subsequent to Prompts Restructuring Oral Muscular Phonetic Targets (PROMPT) intervention. We measured the distribution patterns of voice onset time (VOT) a voiceless stop (/p/) examine coordination. Two standardized tests were used (Verbal Motor Production Assessment Children (VMPAC), GFTA-2) assess skills articulation. Data showed positive VOT lower pattern...
Abstract Background Treatment outcome data for children with severe speech sound disorders motor involvement (SSD‐MSI) are derived from Phase I clinical research studies. These studies have demonstrated positive improvements in production. Currently there is no examining the optimal treatment dose frequency this population. The results of study, which first its kind, will inform delivery effective services Aims To investigate Motor Speech Protocol (MSTP) SSD‐MSI. Methods & Procedures A...
To demonstrate the application of constructs treatment fidelity for research and clinical practice motor speech disorders, using Prompts Restructuring Oral Muscular Phonetic Targets (PROMPT) Fidelity Measure (PFM). Treatment refers to a set procedures used monitor improve validity reliability behavioral intervention. While concept has been emphasized in medical allied health sciences, documentation systematic evaluation Speech-Language Pathology is sparse.The development iterative process...
Purpose The aim of the study was to develop and validate a probe word list scoring system assess speech motor skills in preschool school-age children with disorders. Method This article describes development using modified complexity measure principles based on hierarchical control known as Motor Speech Hierarchy (MSH). accounted for factors related (i.e., motoric) complexity, linguistic variables, content familiarity. administered 48 moderate-to-severe delay at clinical centers Ontario,...
Visual and auditory systems interact at both cortical subcortical levels. Studies suggest a highly context-specific cross-modal modulation of the system by visual system. The present study builds on this work sampling data from 17 young healthy adults to test whether speech stimuli evoke different responses in efferent compared non-speech stimuli. descending influences medial olivocochlear (MOC) activity were indirectly assessed examining effects contralateral suppression transient-evoked...
