Filter by:Deep Brain Stimulation (DBS) is a neurosurgical procedure used to treat tremors, and dystonia. This study will enroll people who have a form of focal dystonia that affects their vocal cords called Adductor Laryngeal dystonia (ADLD). Participants will undergo Deep Brain Stimulation surgery to treat laryngeal dystonia as part of their clinical care. Before surgery, as part of the study they will have specialized testing to study the movement of the vocal cords, as well as functional magnetic resonance imaging (fMRI). While in the operating room, researchers will examine brain waves to better understand how faulty brain firing patterns lead to dystonia. After surgery, and activation of the deep brain stimulator, participants will repeat speech testing and vocal cord imaging as well as magnetic resonance imaging (MRI).
Dystonia is involuntary movements characterized by posture abnormalities or repetitive movements as a result of continuous or intermittent simultaneous contraction of opposing muscle groups. Dystonic movements are twisted and twisted in a certain pattern. Dystonia is named in different ways according to its distribution in the body. Cervical dystonia is the most common form of regional dystonia and can be defined as involuntary movements of the head in normal upright posture.Cervical dystonia has different names according to the posture of the neck (torticollis, laterocollis, anterocollis and retrocollis). These different postures can be seen individually as well as together.Pain in cervical dystonia is seen in approximately 70% of patients, and this condition is closely related to involuntary contractions of neck muscles and neck posture disorder. Fatigue, anxiety, unhappiness, decreased self-efficacy and limitation in daily living activities due to decreased neck movements are the main causes of disability in patients with cervical dystonia. The first-line treatment of cervical dystonia consists of injecting botulinum toxin type A into the relevant muscles to alleviate these complaints.There is increasing evidence that range of motion, stretching, and relaxation exercises, in addition to botulinum toxin therapy, have beneficial effects on pain and disability in patients with cervical dystonia.In this study, patients with cervical dystonia who received botulinum toxin type A injection will be divided into study group and control group.The patients in the study group will be given stretching, strengthening, breathing and rhythmic coordination exercises for the muscles involved. (Personalized exercise program) In the control group, only breathing and rhythmic coordination exercises will be given and the two groups will be compared.Thus, it is aimed to investigate the effect of a personalized exercise program on clinical findings and the patient's quality of life.
The general aim of the research is to provide scientific evidence that vibro-tactile stimulation (VTS) represents a non-invasive form of neuromodulation that can induce measurable improvements in the speech of patients with laryngeal dystonia (LD) - also called spasmodic dysphonia (SD).
MEIGES is a prospective, multicenter, randomized controlled clinical trial with the primary hypothesis that, STN-DBS is non-inferior to GPi-DBS for motor symptoms improvements at 365 days postoperatively in patients with idiopathic craniofacial dystonia.
Cervical dystonia is the most common form of focal dystonia in adults (50-82%). It manifests itself by a abnormal attitude of the head, intermittent or permanent, due to involuntary contraction of the cervical muscles which appears or is accentuated on the occasion of voluntary movement and maintenance posture. The distribution of dystonic muscles is specific to each patient explaining the diversity of patterns encountered. The therapeutic management of DC is essentially local and symptomatic. It is based on the realization of injections of neuro botulinum toxin (BoNT) targeting target (dystonic) muscles responsible for involuntary movements or posture abnormal. Identifying the muscles involved is a step prerequisite for therapeutic intervention.The obliquus capitis inferior (OCI) also known as Lower Oblique belongs to the group of suboccipital muscles.It is the only suboccipital muscle that does not attach to the skull. Its unilateral contraction causes ipsilateral rotation of C1 therefore of the head. The length of the transverse process of the atlas gives it considerable rotary efficiency. It is described as the cephalic rotation starter muscle. It would perform the 30 first degrees of rotation. The rotation of the whole column cervical would then be continued by the synergistic action of the muscle contralateral sternocleidomatoid and Spl. ipsilateral. The level of joint complex C1-C2 the amplitude of rotation corresponds to approximately 50% of the total rotation of the cervical spine. In order to better understand the part played by the OCI muscle in the disorganization of posture and cervical movements in the axial plane (plane of rotation) in the rotary DC, the investigators want biomechanically analyze its function in pathological situation. The physiology of this muscle is richly documented in healthy subjects. But does this knowledge apply in DC? Acquisition of imagery by the "Cone Beam" or CBCT system (Cone Beam Computed Tomography) before and 5 weeks after the injection of BoNT, will allow the analysis of the displacement of each vertebrate.
This research involves retrospective and prospective studies for clinical validation of a DystoniaNet deep learning platform for the diagnosis of isolated dystonia.
The researchers will examine functional neural correlates that differentiate between laryngeal dystonia and voice tremor and contribute to disorder-specific pathophysiology using a cross-disciplinary approach of multimodal brain imaging.
HYPNODYS is a single-center study evaluating the evolution of perceived voice-related disability before and after 3 standardized hypnosis sessions in patients with functional dysphonia.
Study of Ingrezza (Valbenazine) for the treatment of cervical dystonia.
The researchers will systematically evaluate current and novel clinical voice assessment tools and measures to elucidate distinct clinical phenotypes of those with laryngeal dystonia and voice tremor.
