Filter by:Parkinson's disease (PD) is the second commonest neurodegenerative disorder, affecting over 145,000 people in the UK. Initially, PD patients experience slowness of movements, limb stiffness, and tremor. With progressive loss of neurons over time, many patients start to experience balance and walking problems, and falls, which are resistant to currently available treatments. Falls can lead to fractures and nursing home admission, and can significantly shorten patients' life expectancy. In this pilot study, the investigators will investigate the effects of spinal cord stimulation (SCS) on gait and balance in PD. Some open-labelled studies have shown possible beneficial effects of SCS in PD, although it is uncertain which type of PD patients will benefit most and which stimulation parameters work best. The investigators will assess the effects of SCS on posture and gait using a series of clinical, laboratory, imaging, and wearable measurements. The participants will receive a percutaneous implantation of a spinal cord stimulator to minimise the possible adverse effects related to the surgery. The SCS will start one month after surgery. The investigators will use a double-blind cross-over design. The participants will receive three different stimulation parameters, including sham stimulation, in a randomised order. The participants and the assessors will be blinded to the stimulation parameters.
Observational cross-sectional study in PD patients and healthy controls (HC) using an investigational medical device consisting of a passive small intestine microbiome aspiration (SIMBA) system (capsule) that is ingested orally and recovered together with the stools (home recovery) together with blood sampling (during the onsite visit).
At present, no drug therapy has been proven to delay the progression of Parkinson's disease (PD). rTMS, as a non-invasive neuromodulation method, can regulate Slow-wave sleep (SWS). SWS is recognized closely related to neurodegeneration. However, there has been no clinical studies on if rTMS could delay the progression of PD by regulating SWS. The main purpose of this study is to explore the changes of SWS in non-rapid eye movement (NREM) sleep period in PD patients by using rTMS, and the relationship with potential improvements of SWS and motor symptom delay. The study aims to find a potential new treatment strategy to delay the neurodegenerative process in PD patients by modulating SWS by rTMS.
Many patients with Parkinson's Disease (PD) report an increased consumption of fast-acting sugars. This tendency to consume sweet, high-sugar foods occurs in some patients even before the onset of cardinal motor symptoms. Some recent studies have demonstrated that PD patients have an increased consumption of fast-acting carbohydrates compared to healthy controls. However, the reason for this change in eating behavior has not yet been adequately explained. It is discussed that the increased sugar intake leads to an increased dopamine release in the brain via an increase in insulin and thus to an improvement in clinical symptoms. This study investigates the influence of fast-acting carbohydrates on insulin and glucose blood levels as well as motor and non-motor symptoms in patients with PD using an oral glucose tolerance test and a placebo oral glucose tolerance test in a crossover design.
Resting tremors associated with Parkinson's disease (PD) remains difficult to quantify and track during disease progression. This study propose to explore the rhythmicity of distal muscle contractions in the upper limb to characterize resting tremor and discriminate it from cerebellar tremor (CT) based on the frequency spectrum of the EMG signal.
The purpose of this clinical trial is to verify the efficacy and safety of rechargeable implantable deep brain stimulation (DBS) system for the treatment of advanced primary Parkinson's disease.
A randomized controlled trial is to be conducted to confirm the efficacy and safety of intramuscular injection of botulinum toxin in the treatment of Parkinson's bladder overactivity.
The purpose of this study is to demonstrate the safety and effectiveness of the PINS Deep Brain Stimulation (DBS) system, including the G107R/G107 IPG, L305/L306 directional leads, E204 extensions and related system components.
The purpose of this single arm study is to evaluate the feasibility and safety of treatments with a non-invasive neuromodulation device in adults diagnosed with mild/moderate Parkinson's disease dementia (PDD). A non-invasive device is a device that stays outside of the body and is not implanted and does not penetrate the skin. Neuromodulation means that the device stimulates activity in the brain.
People living with Parkinson's (PwP) rank balance problems amongst the most disabling symptom. Over time, balance function continues to decline and PwP go on to fall, affecting between 45-68% of PwP. Falling directly impacts upon the individuals' quality of life (QoL), as it prevents patients from doing everyday activities, and places PwP at greater risk of other medical problems, such as fractures. New treatments are urgently needed to improve balance and reduce falls in order to improve QoL for PwP. The aim of this project is to achieve these goals by using exercise to alter brain activity. Supporting our idea, are previous studies that show both exercise alone as well as changing brain activity at rest via visual feedback (similar to how breathing can be controlled to lower blood pressure), can be used to rehabilitate balance. Here researchers test the idea that better results can be achieved for PwP, if a specific exercise program is used as the feedback to change brain activity. PwP will be assigned randomly into 2 groups, one receiving the exergaming physical therapy (PT) alone with a placebo feedback and, the second group will be required to change brain activity using exercise feedback to change brain activity. Each intervention will be performed 3 times/week with each session lasting 1⁄2 an hour, for 12 consecutive weeks. Participants are expected to attend 5 sessions over each fortnight. Assessments of balance will be made before and after all three treatments. This will allow us to measure any improvements and compare the 2 different methods to see which one improves balance the most in PwP.
