Filter by:Dystonias represent hyperkinetic movement disorders characterized by protracted muscle contractions, such as to cause torsional movements and anomalous postures in different parts of the body. Although they occur more often in a focal form (blepharospasm, oromandibular dystonia, cervical dystonia, laryngeal dystonia, attitudinal cramps of the limbs) than segmental (involvement of several contiguous muscle groups, e.g. facial muscles and neck muscles), they are nevertheless capable of significantly influencing the quality of life, with consequent social and health costs. Although described as a predominantly motor disorder, the presence of non-motor symptoms in dystonias associated with alteration of the fronto-striatal circuits is increasingly recognized. Neuroimaging studies have highlighted that the striatum and, more specifically, striatal dopamine, is involved in high cognitive processes such as attention, reward-based learning and decision making. Clinical conditions associated with cortico-striatal circuit dysfunction and abnormal meso-striatal or meso-cortical dopamine transmission also appear to influence temporal estimation, delay discounting, showing an impulsive preference for immediate rewards over delayed gratification. Based on these premises, the present project aims to evaluate the cognitive and affective aspects of dystonias, in line with neuroimaging research documenting structural and functional dysfunctions in the respective brain regions.
In this exploratory qualitative study with a hermeneutic phenomenological approach, we will describe and understand the experience of treatment and hospitalization in hospitalized people suffering from stroke, multiple sclerosis, Parkinson's disease and patients post-neurosurgery for oncological causes. Patients will be interviewed in a semi-structured manner and sampling will take place for each of the pathology groups according to the saturation method.
The purpose of this clinical trial is to learn about the Tremor Retrainer smartphone application and Simplified Functional Movement Disorder Rating Scale in patients with functional tremor. The main questions the study aims to answer are: 1. Is the Tremor Retrainer application usable for patients and are there signs that it can help functional tremor? 2. Can a televideo administration of the Simplified Functional Movement Disorder Rating Scale give enough information to use this scale via televideo in future studies?
Established gait assessments for subjects with spinal cord injury (SCI) (6MWT, 10MWT, TUG, SCIM III and WISCI II) are widely used in the clinical and research setting. So far, no valid measurement exists that assesses the patients' perspective of walking ability in SCI. As there is the 12-item Multiple Sclerosis Walking Scale (12-WS) to assess the patients' perspective on gait ability in patients with multiple sclerosis, it is hypothesized that the 12-WS would also be a valid instrument for subjects with incomplete SCI. The main goal of this study is to collect data from clinical gait assessments in subjects with spinal lesions and to demonstrate that the 12-WS is a valid and reliable patient-reported outcome measurement for individuals with incomplete spinal cord injury.
Muscle behaviour of calf muscles can be studied during dynamic conditions using dynamic ultrasound. In particular, the medial gastrocnemius is suitable for measurements with dynamic ultrasound due to its superficial location. With this measurement technique, the muscle behavior during walking can be observed gaining insight into the mechanism of action of this muscle during a functional task. This technique has already been used in other populations (such as children with cerebral palsy) but not yet in individuals after a stroke. Therefore, the aim of this study is to assess the muscle behavior of the medial gastrocnemius during walking in persons after stroke. There are 3 concrete objectives of the current study: 1. is the technique feasible to perform in persons after stroke? 2. does the use of the dynamic echoprobe change gait patterns? 3. can differences between persons after stroke and healthy controls be detected? This data can be used as pilot data for project applications in the future that will allow to design larger studies. Therefore, 10 stroke patients and 10 age- and gender-matched healthy controls will walk on a treadmill for 3x2 minutes after a familiarisation period of 6 minutes. During 1 x 2 minutes, subjects will walk without using the dynamic ultrasound. This recording aims to measure the normal gait pattern of the subjects. During the other 2x2 minutes, subjects will walk using the dynamic ultrasound at 2 different locations on the calf. Once with the ultrasound probe on the centre of the muscle belly to visualise muscle fibre bundles and once on the muscle tendon transition, from which muscle belly and tendon length can be derived. The use of ultrasound or not will be randomized to exclude the effect of fatigue on the outcome measures.
The study aims to evaluate the safety and efficacy of the Supernova stent retriever device, developed by Gravity Medical Technology, for treating acute ischemic stroke. The device is used to remove blood clots and restore blood flow to the brain .
The aim of this study is to compare ultrasound-guided perineural injection of the median nerve with classic minimal incision surgical technique for median nerve decompression in patients diagnosed with mild, moderate, and severe carpal tunnel syndrome.
This project will enable optimization of specific carried out by occupationist for older adults discharged from hospital for falls: - on the environmental dimension at the participant's home - on the involvement of the caregiver since they are also involved in the care of the patient - on the recurrence of falls and rehospitalizations in order to improve the quality of life by reassuring the elderly person when traveling - on limiting loss of autonomy and staying at home. The occupational therapist will entrust the caregiver with a support role. The participant will feel more involved in the participant's care (thus reducing the feeling of helplessness). His actions will allow him to strengthen his sense of competence and will prevent him from physical and psychological exhaustion.
Autonomic nervous system diseases can cause abnormalities in the circulatory system, leading to malignant arrhythmia and sudden cardiac death. Standardized, operable, and simplified diagnostic indicators are urgently needed to evaluate autonomic nervous function, particularly cardiac autonomic nervous function. The investigators use HUTT in order to provide data support for cardiac autonomic nervous system evaluation.
Transcranial Direct Current Stimulation (tDCS) is a non-invasive, painless brain stimulation treatment that uses low-intensity direct electrical currents to stimulate specific parts of the brain. Transcranial Direct Current Stimulation (tDCS) can both facilitate anodic stimulation and inhibit cathodic stimulation specific brain areas since many neurological and psychiatric disorders are connected to hypoactivity or hyperactivity in specific areas of the nervous system. This phenomenon is based on two processes: the reorganization of functional neural circuits and their reconstruction. In light of the studies mentioned above, it is presumed that Transcranial Direct Current Stimulation (tDCS) can be a valuable tool to facilitate the process of neuroplasticity in individuals with chronic neurological diseases and in patients with impaired consciousness following severe brain injury. A previous study demonstrated that a single session of transcranial direct current electrical stimulation could temporarily improve signs of consciousness in patients in a minimally conscious state (MCS)
