Filter by:The goal of this clinical trial is to investigate the impact of direct vs. indirect caregiver training on treatment outcomes following a period of Dynamic Temporal and Tactile Cueing (DTTC) intervention combined with home practice in childhood apraxia of speech (CAS). Forty children with CAS, between the ages of 2;5 and 7;11 years of age, will be recruited for this study. All children will receive DTTC treatment at the frequency of standard care (2x/week) in a university clinic over and 8-week period. Participants will be randomly assigned to one of two groups: the Direct Training Group; the Indirect Training Group. All caregivers will complete an educational module about CAS, will observe all sessions, and will engage in home practice with their children. Caregivers in the Direct Group will receive coaching in the use of DTTC with their child during a portion of each treatment session to support home practice, whereas those in the Indirect Group will not receive detailed guidance for home practice. Caregivers in both groups will practice at home with their children during the treatment phase (3x/week). Following the treatment phase, home practice will continue at a higher frequency (6x/week) during a 4-week follow-up phase. Treatment outcomes will be compared between groups.
Difficulties with speech and language are the first and most notable symptoms of primary progressive aphasia (PPA). While there is evidence that demonstrates positive effects of speech-language treatment for individuals with PPA who only speak one language (monolinguals), there is a significant need for investigating the effects of treatment that is optimized for bilingual speakers with PPA. This stage 2 efficacy clinical trial seeks to establish the effects of culturally and linguistically tailored speech-language interventions administered to bilingual individuals with PPA. The overall aim of the intervention component of this study is to establish the relationships between the bilingual experience (e.g., how often each language is used, how "strong" each language is) and treatment response of bilinguals with PPA. Specifically, the investigators will evaluate the benefits of tailored speech-language intervention administered in both languages to bilingual individuals with PPA (60 individuals will be recruited). The investigators will conduct an assessment before treatment, after treatment and at two follow-ups (6 and 12-months post-treatment) in both languages. When possible, a structural scan of the brain (magnetic resonance image) will be collected before treatment in order to identify if brain regions implicated in bilingualism are associated with response to treatment. In addition to the intervention described herein, 30 bilingual individuals with PPA will be recruited to complete behavioral cognitive-linguistic testing and will not receive intervention. Results will provide important knowledge about the neural mechanisms of language re-learning and will address how specific characteristics of bilingualism influence cognitive reserve and linguistic resilience in PPA.
Childhood apraxia of speech (CAS) is a pediatric motor-based speech sound disorder that requires a specialized approach to intervention (Maas et al., 2014). The extant literature on the treatment of CAS commonly recommends intensive treatment using a motor-based approach, with some of the best evidence supporting the use of Dynamic Temporal and Tactile Cueing (DTTC; Strand, 2020). To date, a rigorous and systematic comparison of high and low dose frequency has not been undertaken for DTTC, resulting in a lack of evidence to guide decisions about the optimal treatment schedule for this intervention. The current study aims to fill this gap in knowledge by comparing treatment outcomes when dose frequency is varied. The goal of this clinical trial is to determine whether the number of treatment sessions per week has an effect on intervention outcomes in 60 children with CAS. The main question this research will address is whether whole word accuracy will differ between two groups of children undergoing DTTC treatment when one group of children receives treatment twice a week for 12 weeks and the other group receives treatment 4 times a week for 6 weeks. Community clinicians will administer all treatment sessions.
The aim of the study is to evaluate the effects on motor and cognitive performance of transcranial alternating current stimulation (tACS) compared to transcranial direct current stimulation (tDCS) and placebo stimulation (sham) in patients with neurodegenerative ataxia to identify a possible rehabilitation protocol.
Searching of Apraxia of Speech in Children with Specific Language Impairment
The purpose of the study is to test whether low level electric stimulation, called transcranial Direct Current Stimulation (tDCS), on the part of the brain (i.e., pre-supplementary motor area) thought to aid in memory will improve speech and language difficulties in patients with primary progressive aphasia (PPA) and progressive apraxia of speech (PAOS). The primary outcome measures are neuropsychological assessments of speech and language functions, and the secondary measures are neuropsychological assessments of other cognitive abilities and electroencephalography (EEG) measures.
Limbs apraxia is a motor disorder whose characteristic is the inability or difficulty to perform intentional movements of the limbs (gestures), most frequently involving the upper limbs. Recent literature indicated promising effects of transcranial direct current stimulation (tDCS) in the recovery of limbs apraxia, showing that, in stroke patients, excitatory anodal tDCS over left inferior parietal lobe (IPL) may improve limb apraxia. Despite this encouraging evidence, the need for larger well powered and sham-controlled clinical trials has also been identified. For these reasons, the objective of this study is to investigate the effects of tDCS application on the left posterior parietal cortex, associated with the treatment for apraxia made by Smania et al. in 2000, on the recovery of the upper limbs ideomotor apraxia in patients with left brain lesion of vascular origin.
Speaking in unison with another person is included as a part of many treatment approaches for aphasia. It is not well understood why and how this technique works. One goal of this study is to determine who benefits from speaking in unison, and what characteristics of speech are most helpful. Another goal is to investigate a possible mechanism for this benefit: why does speaking in unison help? A possible mechanism for this benefit is examined, by testing whether the degree of alignment of a person's speech with that of another speaker can account for unison benefit.
The purpose of this study is to describe the possible effects of methylphenidate (MPH) on speech intelligibility in children with childhood apraxia of speech (CAS) aged 6-12 years. This outcome will be compared between MPH intake and placebo intake.
Comorbid Childhood Apraxia of Speech (CAS) may be one factor that limits speech development in some minimally verbal children with autism. CAS is a disorder affecting speech movement planning. This study tests whether CAS-specific treatment, appropriately modified for minimally verbal children with autism, improves their speech.
