Filter by:This is a randomized controlled clinical trial aimed at Parkinson's disease patients. Its objective is to evaluate the effects of a dynamic upper limb orthosis to achieve maximum hand functionality, reducing tremor and rigidity
The objective of this prospective observational cohort study is to answer the following clinically important questions: 1. In patients with a pre-operative history of ICBs, what is the likelihood of improvement or deterioration in ICBs post-operatively? 2. What is the risk of developing post-operative de novo ICBs after Subthalamic Nucleus DBS (STN DBS)? 3. Which factors are important in predicting changes in ICBs after STN DBS? 4. What is the impact of ICBs on carer's quality of life QoL and burden?
The present study seeks to examine the efficacy of multi-session transcranial direct current stimulation applied over the primary motor cortex in people with Parkinson's disease on sequential motor learning performance.
Home-based exercise program focusing on axial rigidity could be used as an adjunct rehabilitation program to improve rotational movement, gait and functional movement associated with axial rigidity in individuals with PD.
High-frequency deep brain stimulation (DBS) is an effective treatment strategy for a variety of movement disorders including Parkinson's disease, dystonia and tremor1-5, as well as for other neurological and psychiatric disorders e.g. obsessive compulsive disorder, depression, cluster headache, Tourette syndrome, epilepsy and eating disorders6-11. It is currently applied in a continuous fashion, using parameters set by the treating clinician. This approach is non-physiological, as it applies a constant, unchanging therapy to a dysfunctional neuronal system that would normally fluctuate markedly on a moment-by moment basis, depending on external stressors, cognitive load, physical activity and the timing of medication administration. Fluctuations in physical symptoms reflect fluctuations in brain activity. Tracking and responding in real-time to these would allow personalised approaches to DBS through stimulating at appropriate intensities and only when necessary, thereby improving therapeutic efficacy, preserving battery life and potentially limiting side-effects12. Critical to the development of such adaptive/closed-loop DBS technologies is the identification of robust signals on which to base the delivery of variable high-frequency deep brain stimulation. Local field potentials (LFPs), which are recordable through standard DBS electrodes, represent synchronous neuronal discharges within the basal ganglia. Different LFP signatures have been identified in different disorders, as well as in different clinical states within individual disorders. For example, low frequency LFPs in the Alpha/Theta ranges (4-12Hz) are frequently encountered in patients with Dystonia13,14, while both beta (12-30Hz) gamma (60-90Hz) band frequencies may be seen in Parkinson's disease, when the patient is OFF and dyskinetic, respectively15,16. Equally, suppression of these abnormal basal ganglia signals through medication administration or high-frequency DBS correlates with clinical improvement. As such, they represent attractive electrophysiologic biomarkers on which to base adaptive DBS approaches. Until recently, neurophysiological assessments were purely a research tool, as they could only be recorded either intra-operatively or for a short period of time post-operatively using externalised DBS electrodes. However, advances in DBS technology now allow real-time LFP recordings to be simply and seamlessly obtained from fully implanted DBS systems e.g. Medtronic Percept PC. In this study, we will evaluate a cohort of patients with movement disorders and other disorders of basal ganglia circuitry who have implanted DBS systems. Recordings of LFPs and/or non-invasive data such as EEG, limb muscle activation and movement (surface EMG and motion tracking) under various conditions (e.g. voluntary movement, ON/OFF medications, ON/OFF stimulation) will allow us to evaluate their utility as markers of underlying disease phenotype and severity and to assess their potential for use as electrophysiological biomarkers in adaptive DBS approaches. These evaluations in patients with DBS systems with and without LFP-sensing capabilities will take place during a single or multi-day evaluation (depending on patient preference and researcher availability). This study will advance not only the understanding of subcortical physiology in various disorders, but will also provide information about how neurophysiological and behavioural biomarkers can be used to inform personalised, precision closed-loop DBS approaches.
To test for the first time the potential of a nicotinic agonist on cognitive symptoms in people with mild cognitive impairment (MCI) in Parkinson's disease (PD), referred to as PD-MCI.
This study asks three questions about Persons with Parkinson Disease that use a bicycle for exercise. 1. Does the use of virtual reality increase the intensity and and enjoyment of the experience compared to bicycling without virtual reality? 2. Does the way in which the bicycling (interval compared to continous) is performed affect the experience? 3. How does the way the virtual reality is delivered (with goggles or projected on a screen) affect the experience?
The study by giving a sleep disorder Parkinson's disease patients with different patterns of ultra-low frequency transcranial magnetic stimulation or sham stimulation, scale for assessment of the patients were observed, hematology and imaging changes before and after therapy, clear ultra-low frequency transcranial magnetic stimulation for sleep disorder Parkinson's disease treatment, to explore the mechanism of action, compare the difference between different modes.
This study aims to assess the efficacy of custom-made shoe insoles, for subjects with Parkinson's Disease (PD). To do that, a sample of PD subjects has been randomly assigned to an intervention group that will receive the custom-made insoles or a control group that will receive a sham insole without any specific manufacturing. Both groups will receive Physiotherapy and Occupational Therapy according to PD rehabilitation guidelines. The principal outcome will be the Time Up&Go test time, secondary outcomes 10 Meters Walking test speed, Berg Balance Scale score, SF12 score, and orthesis liking.
This clinical trial is designed to test whether surgically injecting nerve cells that make dopamine into the brain of Parkinson's disease patients is safe, and to monitor for potential side effects.
