Filter by:The purpose of this research study is to investigate how the brain and motor behavior changes in individuals with dystonia in response to exercise training.
The goal of this observational study is to evaluate the cortical silent period (cSP) in cricothyroid muscle (CT) in laryngeal dystonia and control healthy subjects. The study will provide norms related to latency and amplitude of motor evoked potentials (MEPs) and duration of cSP in CT muscle in laryngeal dystonia and control healthy subjects. Findings may give a baseline in comparison to findings in laryngeal diseases and insight into maladaptive cortical control function during phonation in laryngeal diseases like laryngeal dystonia.
The deep brain stimulation is surgical technique used for the Parkinson's disease, essential tremor, dystonia, epilepsy, and psychiatric diseases. A pulse generator or battery (implanted pulse generator, IPG) is a need for replacement every few years. In general, electric cautery(BOVIE), which is commonly used in surgery, cannot be used when the deep brain stimulation machine is inserted, so conventional tools such as scissors and knives are used for replacement surgery. However, in the process, damage to the machine may be inflicted by knives, scissors, etc., and in the worst case, the machine may be unusable, resulting in financial and human consumption. Plasma Blade is currently used for tissue incision and coagulation in Korea, and is the only insurance-recognized tool in Korea for the replacement surgery of a cardiovascular implantable electronic device (CIED). The deep brain stimulation machine has a structure very similar to that of the heart electronics. In addition, the plasma blade was used to replace the deep brain stimulation machine overseas.The safety is reported in the surgery, so the plasma blade deep brain stimulation machine has been replaced in Korea. The investigators would like to check the safety and effectiveness for use in surgery.
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.
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.
This research involves retrospective and prospective studies for clinical validation of a DystoniaNet deep learning platform for the diagnosis of isolated dystonia.
The objective of this registry is to confirm the safety and the performance of the ECE50 in medical routine by collecting data.
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.
The current research protocol aims at studying preparatory inhibition in two populations of patients suffering from movement disorders. First, in PART 1, we will work with Parkinson's disease (PD) patients to investigate the contribution of the basal ganglia in preparatory inhibition (Project 1 [P1] and Project 2 [P2]). Then, in PART 2, we will consider patients with focal hand dystonia (FHD), to test the hypothesis that altered muscle selectivity in this pathological condition is, at least in part, due to a lack of preparatory inhibition.
