Filter by:In patients with chronic illness, screening for falls and their health consequences are major public health issues. Muscle weakness, gait and balance disorders are among the most common risk factors for falling. Assessing these parameters would thus be a crucial step in the evaluation of the risk of falling, allowing to more precisely orient the management strategy. Combining inertial unit sensors with clinically validated tests can provide additional information to improve the assessment of fall risks. We therefore propose to constitute a monocentric exploratory study, testing a prognostic screening tool, in patients suffering from a chronic pathology, in order to assess the risk of falling in this population. Considering the relationship between muscle weakness and the risk of falling, we can assume that a deficit in muscle strength will result in less vertical acceleration which could point to a muscle cause of the balance disorder and thus allow a finer detection of the risk of falling. On the other hand, we hypothesize that spinal static disorders in chronic pathologies and in particular osteoarthritis, as well as balance disorders linked to impaired deep sensitivity lead to an increase in oscillations of the trunk when walking which can cause postural balance disorders thus increasing the risk of falling.
The goal of this project is to develop the international validation of two new rating scales, the Neuropsychiatric Fluctuations Scale (NFS) and the Shame in PARKinson's disease (SPARK) Scale, in order to improve the understanding of the extent and severity of non-motor symptoms in Parkinson's disease (PD).
Walking deficits and altered brain capacity have been proved to be two of the main contributing factors in dual-task walking deficits in patients with Parkinson's disease (PD). In the past, patients with PD were usually suggested not to walk in dual-task conditions in order to concentrate on their walking performance better. However, since dual-task walking is really common in daily-life, this limitation usually lead to a decrease in quality of life for PD patients. In previous studies, effects of using attentional strategies in dual-task walking training remain unclear, while suitable attentional strategies and corresponded neuroplasticity for patients with and without freezing of gait have not been well discussed, either. Accordingly, this study is aimed to identify (1) whether internal or external attentional strategies is more ideal for PD patients with and without freezing of gait in dual-task walking training, and (2) changes in brain activity after receiving dual-task walking training with different attentional strategies in patients with or without freezing of gait. Our hypothesis are (1) patients with or without freezing of gait will react differently in dual-gait training with different attentional strategies, and (2) changes in brain activities will be different according to different attentional strategies given in the training.
Swallowing impairment (dysphagia) is extremely common in older adults living with dementia due to age-related changes in swallowing and other disease-specific impairments. Dysphagia is commonly managed by modifying diet textures rather than engaging in rehabilitative swallowing therapy. This means that countless people with dementia are left to eat pureed foods and drink thickened liquids, which are unpalatable and lead to malnutrition. As the disease progresses, many are transferred to nursing homes. In Canada, speech-language pathologists, who manage dysphagia, are consultants within nursing homes; therefore, swallowing therapy is non-existent. However, exercise therapy is more commonly available. Rodent models have demonstrated that physical exercise strengthens tongue and vocal-fold musculature, which are critical components of swallowing. Therefore, it is possible that whole-body physical exercise, which increases rate of respiration, will help to strengthen swallowing-related musculature in older adults with dementia. In this study, older adults (65+) with early-stage dementia will complete a 12-week physical exercise program to determine improvement of swallowing function.
The purpose of this study is to learn about how deep brain stimulation (DBS) affects brain activity in those with Parkinson's disease (PD) and essential tremor (ET). The effect of therapeutic and non-therapeutic stimulation settings will be assessed. Additionally, DBS effects in the presence and absence of anti-PD medication will be studied. Also of interest are differences in stimulation effects while at rest versus while performing a task.
Compares the patients' scores of UPDRS-III before and six-month after receiving deep brain stimulation for Parkinson's disease under MAC or AAA anesthesia.
The long-term goal of this work is to maintain or improve daily function of people with PD by addressing cognition. The overall objective is to discover interventions that aid in cognitive functioning. The central hypothesis is that engagement in an improvisational dance (ID) class will benefit cognition among people with PD. Improvisational dance involves spontaneously generated movement, similar to how one moves in everyday life. The literature shows that ID classes positively impact motor impairments associated with PD, such as balance, gait, and functional mobility. Along with being physically demanding, ID requires the use and coordination of a number of cognitive capacities to properly execute movements. This type of activity challenges, and thus may strengthen, cognitive processes such as motor planning, decision making, flexible thinking, initiation, and execution, which may give people cognitive based strategies to be utilized in various aspects of daily life. By improving motor function and/or cognition, ID may also contribute to improved daily functioning, or the ability to perform and participate in daily activities. Despite these theoretical links, evidence for the effect of ID on cognition and overall daily function is limited. The current project objective is to address this gap and better understand the effects of ID for people with PD. Specifically, it will test the effect of IMPROVment®, a method of ID designed for people with PD, on cognition and daily function. Participants' cognition will be assessed at baseline (T1) using the NIH Toolbox Cognitive Battery, the Alternate Uses Task, and the Weekly Calendar Planning Activity. Global cognition will be assessed using the Montreal Cognitive Assessment. They then will be randomly assigned to either the immediate intervention (ID) or waitlist-control (WC) group. The ID group will start the 12-week IMPROVment® intervention, which consists of weekly ID classes that progress according to a standardized method while the WC group will receive no intervention and continue with their regular daily routine and activity level. After 12 weeks, both groups will complete cognitive testing again (T2). Cognitive test scores will be compared across time points and between groups using a mixed model repeated measures ANOVA. The investigators hypothesize that IMPROVment® will have positive effects on the cognitive abilities of people with PD. Participants will also complete two questionnaires to assess daily function at T1 and T2: Older Americans Resources and Services Scale- Extended Version and PROMIS Satisfaction with Participation in Discretionary Social Activities. These scores will be compared similar to the above aim. The investigators hypothesize that IMPROVment® will have positive effects on daily function in people with PD. Participant mood will be assessed in two different ways. The first being to investigate the immediate effect of participating in an IMPROVment® class on mood, fatigue, and anxiety. The investigators hypothesize that mood will positively improve from pre to post of each class. To assess this, participants will respond to a scale assessing mood, specifically sadness, nervousness, energy, and overall well-being before and after each class every week. The second measurement is to investigate the effect of IMPROVment® on anxiety, fatigue, and depression. The investigators hypothesize that IMPROVment® class will decrease feelings of depression for those with PD. All participants will fill out the Parkinson's Anxiety Scale, the Parkinson's Disease Fatigue Scale, and the Geriatric Depression Scale short form before and after participating in the 12-week IMPROVment® program. Achievement of these aims will provide further support for the IMPROVment® method for people with PD experiencing cognitive deficits. The long-term impact will better cognition and daily functioning in people with PD, and thus enhanced everyday lives.
This study evaluates the differences in cognitive function between healthy older adults, older adults with mild Alzheimer's type dementia and older adults with Parkinson's disease and if there are differences in valence assessment and activation that produce them a mood induction task. Subjects are assessed using neuropsychological tests and then a mood induction task based on movie clips is applied.
