Filter by:This longitudinal study aims to research cognitive and gait phenotypes of Parkinson's disease and Supranuclear Palsy as well as to provide markers to track diseases progression using a multi-modality approach based on 3D-gait analysis and MR Imaging. Specifically, this study want to identify cognitive pattern and gait-related cerebral diffusion/functional connectivity in PD and PSP patients and to verify their progression over a period of 18 months. In summary, the current protocol proposed to investigate the following issues: - to perform a multifactorial quantitative analysis of outcomes for PD and PSP compared to a control group in order to categorize cognitive and gait pattern in the group of patients and verify if the gait can be useful as discriminator for diagnosis. - to analyze whether diffusion and resting-state functional connectivity indices are correlated with clinical disease severity scores and motor scores and how they change over time (18 months later).
The purpose of this study is to demonstrate that young plasma infusions can be performed safely in patients with Parkinson's Disease (PD). Secondary outcomes will include behavioral and laboratory data that will support the next study that will inquire whether young plasma infusions improve or slow the progression of cognitive, mood and/or motor impairment and rate markers of the disease.
Gait initiation (GI) difficulty is common in people with Parkinson's disease (PD). Studies showed that the GI difficulty was related to impaired anticipatory postural adjustments (APA). In healthy people, two phases of APA related center of pressure (COP) shifting were observed before GI. In people with PD, delay and decrease amplitude of APA or abnormal multiple APAs were observed during GI. Conventional balance tests record the maximum displacement and/or velocity of Center of pressure (COP). However, these variables could not show the performance of APA. Previous studies suggested that balance and gait initiation were controlled by separate neural circuitries. This could explain why the conventional COP measurement did not correlate to GI very well. It is important to develop GI related APA tests and trainings. Researchers found that a perturbation applied before the COP displacement during GI could delay both GI and APA. This indicates that COP displacement has APA components. Our pilot study shows that there is a reverse direction of COP displacement before voluntary COP displacement, suggesting the existence of APA. This three year project will evaluate the relationship of the APA of voluntary COP displacement and the APA of GI, establish the APA test for PD, and investigate the effect of APA training on GI in people with PD. In the first year, 20 people without disability will be recruited. The APA before voluntary COP displacement test, APA before GI, and gait performance will be evaluated. In the second year, 15 people with PD and 15 healthy people will be recruited. Subjects will receive GI test, gait test, and APA before voluntary COP displacement test. The relationship between different types of APA will be established for PD and healthy people. In the third year, 30 people with PD will be randomized into APA training group, balance group, and control group. The different training effect will be evaluated especially on GI, gait performance, and freezing of gait. This project will advance the knowledge of mechanism of GI difficulty. The result of this project can be applied to clinical rehabilitation of people with GI difficulty.
This is an open-label, postmarketing, observational study to document health outcomes, in Canadian patients with advanced Parkinson's disease and long-term treatment with Duodopa (levodopa/carbidopa intestinal gel).
Fatigue is one of the most common symptoms in individuals with Parkinson's Disease (PD). Past research indicated that more than half of the individuals with PD demonstrated fatigue symptom. The severity of fatigue was also correlated to the quality of life in individuals with PD. Finding the contributions of the central and the peripheral factors to fatigue and developing an effective training program for individuals with PD are very important. Fatigue can be categorized into peripheral or central causes. The central fatigue and voluntary activation failure originate from the decrease in motivation or the reduction of the conduction within corticospinal tracts. Long term activation failure and central fatigue will cause disuse of muscle and result in peripheral weakness and peripheral fatigue. Quantifying the weighting of central versus peripheral factors contributing to the fatigue in people with PD is important. Most of the conventional strength and endurance training programs were based on the researches of young groups. Almost no training program was design for enhancing the voluntary activation level and relief the central fatigue. Seeking an appropriate training program to enhance central activation is very important for individuals with PD who prone to fatigue. Previous studies have shown that increasing afferent input by peripheral electrical stimulation (ES) at sensory threshold enhanced the plasticity of contralateral primary sensory cortex, the excitability of corticospinal tracts, and the functional performance in young adults. Combining afferent input with strength training was more effective than strength training along. ES, which is easy to quantify the dose of afferent input, is a feasible method to provide such training. The purpose of this project is to investigate the effects of the combination of ES at sensory threshold and strength training on voluntary activation in the individuals with PD.
