Filter by:Writer's cramp is a focal dystonia characterized by abnormal movements and postures during writing. Limited finger independence during writing manifests as difficulty suppressing unwanted activations of neighbouring non task-relevant fingers. Patients with Writer's cramp also have difficulty in fine control of grip force. The investigators have recently developed the Finger Force Manipulandum which quantifies the forces applied by each fingers in different tasks. This method is sensitive for detection and quantification of small unwanted contractions in non-active ('stationary') fingers. Different tasks have been developed to assess abilities such as finger individuation but also fine finger force control, finger movement regularity and speed. The aim of this study is to assess if developed tasks allow to precisely characterize writer's cramp condition in terms of abilities aforementioned. To do so, performance of 20 writer's cramp patients in the developed task will be compared with performance of 20 control participants (matched in age, sex and writing hand) in the same tasks.
Health bones allow us to move and walk freely without pain. Physical activities have been shown to relate to healthy bone growth. Children with physical disabilities are not able to do the same amount of exercises as their healthy peers. They are vulnerable to poor bone health, bone pain, and at high risk of osteopenia or even broken bones. This problem will extend to their adulthood. Recently, whole body vibration therapy (WBVT) has been proven to improve bone health and muscle function in healthy adults and post-menopausal women. Promising results have been shown on gross motor skills, balance and muscle strength for children and young adults with mild cerebral palsy (CP). Most of the vibration protocols require the participants perform some simple exercises on the vibration platform. Very limited studies have been done on children and young adults with moderate CP and almost none solely on individuals with dystonia CP. We do not know if the effect of the WBVT on individuals with dystonia CP would be the same as those with spastic CP and on those with moderate CP as those with mild CP. We also do not know if static standing on the vibration platform would have similar effects on tone abnormalities, balance and gross motor skills as doing simple exercises on the vibration platform because children and young adults with dystonia CP may not be able to freely do simple exercises on the vibration platform without extra support. The present pilot study is to systematically investigate the effects of WBVT on tone abnormalities, balance and functional abilities in children and young adults with dystonia CP.
Magnetic resonance imaging (MRI) of patients implanted with deep brain stimulation (DBS) is under strict safety guidelines. Depending on the body part being imaged, the safety may vary. Many DBS patients will need a spine MRI based on their clinical symptoms. However, the vendor safety guidelines are limiting in terms of possible MR pulse sequences. Based on phantom safety data, we designed a set of MR pulse sequences deemed as safe as possible and the protocol allows acquisition of diagnostic quality MRI images.
Functional neurological disorders (FND) are neurological symptoms that cannot be explained by a lesion or related to an identified dysfunction of the central nervous system. FND are under-diagnosed, although common and highly disabling. Childhood trauma events are found in 30% to 80% of FND patients, and are more common in people with functional neurological disorder than in healthy controls and patient controls. Overall, risks factors, perpetuating factors and maintaining factors have been described in FND, although none of the studies have analysed the prevalence of Early Maladaptive Schemas (EMS) in these patients. EMS, as measured with the Young Schema Questionnaire (YSQ), are proposed to underlie a variety of mental health problems, in particular Personality Disorders. We hypothesize that some of these early maladaptive schemas may participate in the psychopathology and severity of FND. The main outcome of this study is to assess the prevalence of early maladaptive schemas in patients presenting with Functional Movement Disorders in comparison to patients presenting with Parkinson's Disease or Organic Dystonia. The secondary outcomes are to further analyse the underlying relation of these early maladaptive schemas and (i) the severity of the motor symptoms, (ii) anxiety and/or depression, (iii) the occurrence of childhood trauma events in our participants.
The primary objective of this study is to characterize real-world clinical outcomes of Deep Brain Stimulation (DBS) using retrospective review of de-identified patient records.
This study was conducted to assess the combine role of Physiotherapy by providing task specific trainings and Botulinum Toxin Type A in improving the functional outcomes of upper limb in post stroke patients with focal hand dystonia.
Phase 3, open-label, multi-center trial to evaluate the long-term safety, efficacy, and immunogenicity of up to four continuous treatment cycles of daxibotulinumtoxinA (DAXI) for injection.
This is a randomized, double-blind, placebo-controlled, parallel group, multi-center trial of two doses of daxibotulinumtoxinA (DAXI) for injection (high-dose; low-dose in adult subjects with isolated (primary) cervical dystonia (CD).
The study involves the use of a novel, non-invasive, monitoring device to measure the response to treatment with botulinum toxin injections in 24 (16 Intervention and 8 control) patients with cervical dystonia. A baseline assessment, prior to botulinum treatment,will be structured around validated clinical rating scales for cervical dystonia and questionnaires and the performance of simple neck movements, and will be undertaken while the patient wears a movement sensor attached to the head with an elastic strap. The same assessments will be undertaken at 0, 3, 6, 9 and 12 weeks following treatment to assess response. The patients' treatment will not be affected by their participation in the research. The device readings will then be compared with the clinical ratings to establish whether it might be used as a more sensitive measure of treatment response than clinical assessment alone. This will help clinicians to plan and execute botulinum injections more effectively in future
This is an exploratory pilot study to identify neural correlates of specific motor signs in Parkinson's disease (PD) and dystonia, using a novel totally implanted neural interface that senses brain activity as well as delivering therapeutic stimulation. Parkinson's disease and isolated dystonia patients will be implanted unilaterally or bilaterally with a totally internalized bidirectional neural interface, Medtronic Summit RC+S. This study includes three populations: ten PD patients undergoing deep brain stimulation in the subthalamic nucleus (STN), ten PD patients with a globus pallidus (GPi) target and five dystonia patients. All groups will test a variety of strategies for feedback-controlled deep brain stimulation, and all patients will undergo a blinded, small pilot clinical trial of closed-loop stimulation for thirty days.
