Active clinical trials for "Speech Disorders"

The investigators are studying how speech is effected by jaw and tooth position in jaw surgery patients. Eighty percent of our jaw surgery patients have speech pathologies, compared to five percent of the general population, but speech pathologists do not understand why. The investigators hypothesize that open bites and underbites prevent most patients from being able to pronounce words normally and surgical correction will lead to improvement in speech. Patients will be audio recorded speaking and patients' tongue gestures ultrasound recorded before and after their jaw surgeries to observe what changes occur in their speech and tongue movements.

Verbal fluency test require to produce as much words as possible in one or two minutes. This test is highly sensitive to main brain diseases and are therefore widely used in clinical routine for diagnostic purpose. The verbal fluency task requires several cognitive processes including executive and linguistic processes for which it is difficult to extract the origin of the deficit. For this reason, fluency tests are variably interpreted in terms of executive or language. The implementation of an experimental protocol exploring each of these processes separately and studying the links between the verbal fluency task and each of these processes should allow a better understanding of the origin of the verbal fluency deficit after brain injury and improve the identification of key brain structures. Indeed, the lesion determinants of this task remain to be clarified despite remarkable advances due to the evolution of imaging techniques (voxel-based lesion-symptom mapping (VLSM); voxel-based morphometry (VBM)). Furthermore, while the direct assessment of linguistic process, semantic memory, and processing speed is well defined, the examination of the executive component (i.e., strategic search process) remains unsettled and will be undertaken in this study. This work will take advantage of data from previous multicenter work, validated methodologies for both analysis and interpretation of cognitive performance as well as anatomic-clinical correlations at the voxel level and will be performed in cognitive neurodegenerative and cerebrovascular disease.

To perform a multi-site prospective study assessing, both subjectively and objectively, the gender disparities in speech outcomes of patients using TEP after total laryngectomy. The investigators hypothesize that speech outcomes, both subjective and objective measures, will be significantly poorer for female patients compared to male patients. The outcome of the study is to prospectively assess both subjective and objective gender disparities in voice and speech outcomes of patients using TEP after total laryngectomy across a multiple institutions. The investigators hypothesize that both subjective and objective measurements of voice, speech and quality of life will be poorer for female patients in comparison to male patients.

The goal of this longitudinal study is to learn more about the articulatory consequences of surgical oral cancer treatment. The main aims are to study the coordination and development of speech articulation of patients who will undergo surgical treatment for oral cancer longitudinally and whether individual differences in the reliance on auditory or tactile information can predict the success of speech compensatory strategies. Participants will perform multiple speech tasks while motion tracking sensors track the articulatory gestures.

The study proposes to identify deviant speech dimensions in patients with HD at presymptomatic and declared stages of the disease, compared to healthy subjects, using the computerized MonPaGe speech protocol. This tool is based on a multidimensional and quantified assessment of voice and speech, by a set of targeted acoustic and perceptual criteria.

The investigators have designed an innovative proof-of-concept trial designed to provide data as to whether the speech difficulties in children with developmental dysphasia (DD) are improved with intranasal inhalations of bioactive factors (BF), produced by macrophages of M2 phenotype (M2-BFs). The rationale for this approach is the ability of central nervous system (CNS) to repair and the important role of macrophages in the regulation of this process. It was found that type 2 macrophages (M2) have anti-inflammatory and neurorestorative potential, in contrast to pro-inflammatory and neurotoxic effects of М1 cells. The influence of M2 is largely realized through the production of a wide spectrum of bioactive factors (cytokines, chemokines, growth factors, neuropeptides, microvesicles etc) that inhibit inflammation, protect neurons from apoptosis, stimulate neurogenesis, the growth and remyelination of axons, the formation of new synapses and activate angiogenesis. This study uses M2-BFs, as therapeutic tool, and intranasal administration focusing on nose to brain transport, as a mode of delivery. Expected clinical effects in treated children: improvement of speech understanding, word formation, grammatical structure of speech and formation of coherent speech.

The purpose of this investigation is to further develop and test a treatment for word-finding problems in aphasia. The treatment is designed to strengthen meaning associations within categories of words (e.g., animals, tools, fruits). The treatment is also designed to be used as a search strategy in instances of word-finding difficulty. The study was devised to evaluate the extent to which treatment increases the ability to recall trained, as well as untrained, words.

The purpose of the proposed research is to examine the effects of two treatment approaches on speech production involving speakers with chronic apraxia of speech (AOS) and aphasia. The planned investigation is designed to examine the acquisition, maintenance and generalization effects of each treatment. One approach, electropalatography (EPG) uses visual biofeedback in conjunction with articulatory-kinematic treatment and the other approach, sound production treatment (SPT) is one of the most systematically studied articulatory-kinematic treatments for AOS.

The purpose of this study is to carry out a high-level treatment efficacy study on children with speech sound disorders with motor speech involvement (SSD-MSI) using a well-controlled Randomized Controlled Trial design. The intervention of choice is the Prompts for Restructuring Oral Muscular Phonetic Targets (PROMPT) approach, which has been effective in treating motor speech disorders in adults and in children with autism and cerebral palsy.

Late-acquired sounds, such as /r/ are difficult to learn and many children experience persistent errors on these sounds. The purpose of the present study is to determine whether treating these sounds earlier in the child's life may result in better outcomes.
