Active clinical trials for "Dysphonia"

Following a thyroidectomy, voice and swallowing alterations, which more frequently would appear to be caused by lesions of the laryngeal nerve, may occur. But, voice and swallowing changes can also occur in the absence of lesions of the inferior laryngeal nerve or the external branch of the superior laryngeal nerve, defining a condition called central compartment syndrome or functional post-thyroidectomy syndrome. It has been demonstrated that, in the presence of the aforementioned syndrome, the quality of the voice undergoes a deterioration immediately after thyroidectomy surgery with a lowering of pitch. The purpose of this study will be to verify the effects of early speech therapy, including pre-operative speech therapy counseling (during which the patient will be provided with indications to be implemented in the immediate post-operative period).

Overlapping gastrointestinal symptoms of functional gastrointestinal diseases (FGIDs) is an internationally recognized problem in modern medical diagnosis and treatment. Such patients show more physical symptoms and worse quality of life, resulting in a huge economic burden. At present, FGIDs gastrointestinal symptoms overlap, lack of effective and systematic treatment, and the treatment goal is to improve symptoms.The study plans to carry out a multi center and large sample RCT clinical study of Tongjiang granule in the treatment of overlapping gastrointestinal symptoms of non erosive reflux disease(NERD)and epigastric pain syndrome（EPS, so as to provide high-level evidence-based evidence for the treatment of overlapping symptoms of FGIDs and form a diagnosis and treatment scheme that can be popularized.

This study aims to identify adjuvant methods to improve patient comfort during in-office laryngology procedures.

This study is to assess the efficacy of intraoperative intravenous nonsteroidal anti-inflammatory drug (ketorolac) versus intravenous (dexamethosone) administration on dysphagia and dysphonia after ACDF.

Laryngeal dystonia (LD) causes excessive vocal fold abduction (opening) or adduction (closing) leading to decreased voice quality, job prospects, self-worth and quality of life. Individuals with LD often experience episodic breathy voice, decreased ability to sustain vocal fold vibration, frequent pitch breaks and in some cases, vocal tremor. While neuroimaging investigations have uncovered both cortical organization and regional connectivity differences in structures in parietal, primary somatosensory and premotor cortices of those with LD, there remains a lack of understanding regarding how the brains of those with LD function to produce phonation and how these might differ from those without LD. Intervention options for people with LD are limited to general voice therapy techniques and Botulinum Toxin (Botox) injections to the posterior cricoarytenoid (PCA) and/or TA (thyroarytenoid) often bilaterally, to alleviate muscle spasms in the vocal folds. However, the effects of injections are short-lived, uncomfortable, and variable. To address this gap, the aim of this study is to investigate the effectiveness of repetitive transcranial magnetic stimulation (rTMS), a non-invasive neuromodulation technique, in assessing cortical excitability and inhibition of laryngeal musculature. Previous work conducted by the investigator has demonstrated decreased intracortical inhibition in those with adductor laryngeal dystonia (AdLD) compared to healthy controls. The investigators anticipate similar findings in individuals with with other forms of LD, where decreased cortical inhibition will likely be noted in the laryngeal motor cortex. Further, following low frequency (inhibitory) rTMS to the laryngeal motor brain area, it is anticipated that there will be a decrease in overactivation of the TA muscle. To test this hypothesis, a proof-of-concept, randomized study to down-regulate cortical motor signal to laryngeal muscles will be compared to those receiving an equal dose of sham rTMS. Previous research conducted by the investigator found that a single session of the proposed therapy produced positive phonatory changes in individuals with AdLD and justifies exploration in LD.

The purpose of this study is to evaluate the effects of pyridostigmine (Mestinon) on patient vocal outcomes after undergoing laryngeal botulinum neurotoxin (BoNT) injections, which is a standard treatment for spasmodic dysphonia. Pyridostigmine (Mestinon) has been used for treatment of BoNT overdose, and it is our hope that it will be beneficial in the management of post BoNT breathy phase.

This proof-of-concept study is designed to evaluate whether a pedagogic technique used to help performers, known as the Complete Vocal Technique (CVT), can be used to help patients with a type of voice disorder known as Muscle Tension Dysphonia (MTD). MTD is responsible for up to 40% of patients presenting with voice and throat complaints. MTD is due to inefficient or ineffective voice production resulting from an imbalance in the control of the breathing mechanism, and uncontrolled constriction of the muscles in the larynx (voice box) or vocal tract (throat space above the vocal cords). Standard treatment is Voice Therapy delivered by a specialist Speech Therapist (SLT-V) often using a video link (telepractice aka telehealth). CVT is widely used in Europe by singers and vocal coaches. Practitioners (CVT- Ps) undergo a three-year accredited training programme, and the systematic and structured approach helps healthy singers and other performers optimise the function of the voice to produce any sound required. It also helps if the performer has vocal problems, which are also mainly due to uncontrolled throat constrictions. The purpose of this pilot study is to see if the CVT voice therapy approach (CVT-VT) can help, and offers advantages, to standard SLT-V methods in the treatment of patients with MTD. Ten adult patients will be recruited from the Voice clinic at Nottingham University Hospital. Participants will have a multidimensional assessment using questionnaires, and voice recordings and then receive up to 6 video sessions of CVT-VT delivered using a video link by a CVT-P. The participants will then be reviewed back in clinic at 8 weeks and be reassessed, using further questionnaires and analysis of the voice pre- and post-therapy recordings, to evaluate the outcome of this treatment approach. Qualitative methodology will determine whether CVT-VT offers any therapeutic advantages to existing SLT-VT treatment methods.

The gut microbiota is critical to health and functions with a level of complexity comparable to that of an organ system. Dysbiosis, or alterations of this gut microbiota ecology, have been implicated in a number of disease states. Fecal microbiota transplantation (FMT), defined as infusion of feces from healthy donors to affected subjects, is a method to restore a balanced gut microbiota and has attracted great interest in recent years due to its efficacy and ease of use. FMT is now recommended as the most effective therapy for CDI not responding to standard therapies. Recent studies have suggested that dysbiosis is associated with a variety of disorders, and that FMT could be a useful treatment. Randomized controlled trial has been conducted in a number of disorders and shown positive results, including alcoholic hepatitis, Crohn's disease (CD), ulcerative colitis (UC), pouchitis, irritable bowel syndrome (IBS), hepatic encephalopathy and metabolic syndrome. Case series/reports and pilot studies has shown positive results in other disorders including Celiac disease, functional dyspepsia, constipation, metabolic syndrome such as diabetes mellitus, multidrug-resistant, hepatic encephalopathy, multiple sclerosis, pseudo-obstruction, carbapenem-resistant Enterobacteriaceae (CRE) or Vancomycin-resistant Enterococci (VRE) infection, radiation-induced toxicity, multiple organ dysfunction, dysbiotic bowel syndrome, MRSA enteritis, Pseudomembranous enteritis, idiopathic thrombocytopenic purpura (ITP), and atopy. Despite FMT appears to be relatively safe and efficacious in treating a wide range of disease, its safety and efficacy in a usual clinical setting is unknown. More data is required to confirm safety and efficacy of FMT. Therefore, the investigators aim to conduct a pilot study to investigate the efficacy and safety of FMT in a variety of dysbiosis-associated disorder.

Primary muscle tension dysphonia is a voice disorder that involves excessive and poorly coordinated muscle activity affecting multiple subsystems that are involved in speech production, in the absence of structural or neurologic abnormalities of the larynx. Primary muscle tension dysphonia (MTD) is one of the most common forms of voice disorders, accounting for at least 40% of patients seen in voice clinics. Perceptually the voice sounds hoarse and strained, with reduced loudness and pitch range, and people with MTD find speaking very effortful and fatiguing. The physiological abnormalities that characterize MTD are considered multifactorial, and include over-activity of muscles in and around the larynx, laryngeal constriction patterns, and abnormal speech breathing patterns. However, standard treatment approaches for MTD primarily address laryngeal function, including repositioning of laryngeal structures, reducing activity in the intrinsic and extrinsic laryngeal muscles, and altering vibratory patterns. Although voice improvement may follow these treatments, many people with MTD show recurrence of voice problems after only a few months, and some do not improve with treatment. These findings highlight the need for alternative treatments that address the respiratory contributions to MTD, which directly affect the phonatory system. The goal of this project is to compare the effects of two respiratory-based training conditions in people with MTD. A randomized group design will be implemented to determine the respiratory and acoustic effects of each condition. We will determine the effects of each condition immediately after and then 3 and 6 months after training completion to assess short- and long-term training effects. We propose that respiratory training will have a positive effect on related laryngeal behavior and voice. The proposed project has the potential to substantially advance the evidence-based treatment options for MTD, providing a vital step toward reducing the debilitating effects of this disorder.

The purpose of this study is to determine if there are differences in treatment outcomes between traditional voice therapy, performed weekly for a maximum of 6 weeks versus intensive voice therapy, consisting of 4-6 therapy sessions performed within one day.
