Filter by:Functional neurological disorders are an important subgroup of patients with stroke mimics admitted to stroke unit.Their clinical profile and outcome are poorly known. The goal of this study is to describe the cognitive and behavioral profile of stroke mimics patients, without evidence of neurological disease.
The purpose of this study is to determine the feasibility of producing artificial vision in persons with blindness. Study participants will have wireless electrical stimulators implanted into the cortical vision processing areas of their brains. The ability of the participants to perceive artificial vision in response to electrical stimulation will be assessed.
This two-group, randomized control trial (RCT) will test the effects of a home-based, 16 week gait/balance training plus resistance (exercise bands) exercise program as compared to an educational cancer survivorship attention control condition to address persistent taxane-induced peripheral neuropathy in 312 patients treated for invasive breast cancer with taxanes at 1 year or more after completion of therapy. Assessments of lower extremity muscle strength, gait/balance, nerve conduction, neuropathy symptoms, and quality of life (QOL) will be performed. The proposed exercise intervention addresses gait/balance impairments and motor (resistance) components of taxane-induced peripheral neuropathy. The mechanism by which the intervention achieves the proposed outcomes is though 1) increasing endoneurial blood flow to peripheral nerves and mitochondria resulting in reduction in neuropathic symptoms (including pain) and clinical manifestations of peripheral neuropathy, while improving gait/balance in those with persistent neuropathy; 2) The subsequent increase in nutrient supply allows the mitochondria to function more efficiently, and may alleviate the neuropathic manifestations of taxane-induced peripheral neuropathy. 15 This is the first study proposing to test the home-delivery of an exercise intervention specifically aimed at persistent (long-term) taxane-induced neuropathy. If successful, this study will provide the only evidence-based intervention for patients suffering from persistent neuropathy from neurotoxic chemotherapy. Additionally, the home-delivery format makes this intervention easily translated into clinical practice. Specific Aims: In a sample of patients who completed a taxane-containing chemotherapy regimen (> 1 year) for breast cancer and who have a persistent neuropathy (VAS score of > 3) the specific aims of this RCT are: 1. To test the efficacy of a 16-week -delivered program of gait/balance training plus resistance exercise, compared to an educational attention control condition in increasing muscle strength, improving gait/balance and nerve conduction parameters, decreasing the severity of taxane-induced peripheral neuropathy symptoms, and increasing quality of life. 2. To evaluate for differences in muscle strength, gait/balance, sensory (sural) and motor (peroneal) nerve conduction, peripheral neuropathy symptoms, and quality of life (QOL) between patients who receive the exercise program, compared to those in an educational attention control condition controlling for age, BMI, taxane cycles and intervals, neuropathic pain, neuropathy/pain medications, current resistance exercise participation and falls/near falls experienced.
The most common form of dementia is Alzheimer's disease, with 900,000 people affected in France in 2015 and a forecast of 1.3 million in 2020. As a consequence of their advanced age, dementia patients often suffer from pain, mainly musculoskeletal or neuropathic pain. However, the exact prevalence of pain in dementia is underestimated. Indeed, several studies indicate that people suffering from dementia report less pain. This phenomenon is all the more true as the stage of dementia is advanced. In addition, people with dementia receive less pain medication than people without cognitive impairment in similarly painful conditions. Hetero-evaluation alone also seems insufficient, with the result that pain is under-treated compared to patients without cognitive impairment. Better pain screening is a major challenge and self-assessment tools should be favoured as a first line of treatment, even for patients with cognitive impairment. suffering from dementia. The investigators propose in this work to evaluate the variation of vegetative parameters that accompany a painful stimulus. These variations can be recorded at the cardiac, vascular, pupillary or skin conductance level.
This study aims to evaluate perceived clinical and psychosocial experiences of patients and their families during the Covid-19 pandemic. it is important to understand the implications of the pandemic for this population, particularly given its likely protracted course, and resultant limitations to daily activities and clinical care. This will help clinicians plan support and adaptations to the services they provide in the medium to long term.
Antibody-mediated inflammatory diseases of the nervous system (also known as autoimmune diseases of the nervous system) are autoimmune diseases in which autoimmune cells and immune molecules attack the nervous system as the main pathogenic mechanism. In the immune response, pathogenic antibodies acting on autoantigens of the nervous system are collectively referred to as autoantibodies of the nervous system, and antibody-mediated inflammatory diseases of the nervous system can occur in the central nervous system, peripheral nervous system, and neuromuscular junctions, and muscles. In this study, we will recruit eight kinds of autoimmune diseases of nervous system including Neuromyelitis Optica Spectrum Disorder (NMOSD), Myasthenia Gravis (MG), Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP), idiopathic inflammatory myopathyand (IIM), multiple sclerosis (MS), autoimmune encephalitis (AE), Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease (MOGAD) and POEMS Syndrome. B-cell maturation antigen (BCMA) is expressed on the surface of plasma cells, thus making it an ideal target for targeted therapies. Chimeric antigen receptor (CAR) T cells against BCMA offers another potential therapeutic option to eliminate plasma cells in patients with neurological autoimmune diseases driven by abnormal antibody who still suffer recurrent attacks from conventional treatments. In the current study, the safety and efficacy of a novel CAR-T cell therapy using CT103A cells, are evaluated in patients with relapsed/refractory antibody-mediated idiopathic inflammatory diseases.
This is a clinical trial to determine the feasibility of a stationary aerobic cycling intervention and explore if aerobic exercise independently promotes remyelination in people with multiple sclerosis (MS).
Spinal cord stimulation (SCS) has been suggested by several research for treating PD gait disturbance. However, the side effects induced by body position change cannot fully addressed by conventional SCS. Medtronic sensor-driven position-adaptive SCS are capable to monitor the position change and change the parameters accordingly, so as to reduce the position change related side effects. Nevertheless, neither the efficacy nor safety of this technique in the treatment of gait disturbance in PD is ever investigated. Therefore, the investigators will conduct a randomized clinical trial to investigate the clinical efficacy and safety of sensor-driven position-adaptive SCS in the treatment of gait disturbance in PD. This study will contribute to find out the safety and efficacy of sensor-driven position-adaptive SCS in the treatment of PD gait disorder, improve patients' quality of life, and reduce the burden on family and society.
Stroke survivors frequently show persistent gait deficits in their chronic stages even after years of intensive rehabilitation. This may be caused by diminished capability of re-acquiring motor skills post stroke. Thus, the overall purpose of this research project is to examine stroke survivors' capability of learning a novel leg task over 3 visits, 1-2 weeks apart. The capability of learning a new skill is then correlated with the individual's neurological functions (nerve activity and movement coordination) and her/his gait performance (gait speed, gait symmetry, and force production).
The purpose of the study is to evaluate whether non-invasive stimulation over the spinal cord at the neck and/or lower back can improve walking function for people with neurologic conditions. Spinal stimulation has been used extensively for individuals with spinal cord injury, and has demonstrated improvements in function. This study will extend this work to other neurologic conditions, such as cerebral palsy and stroke, that also demonstrate similar impairments as spinal cord injury. The primary aims of this study are to: Aim 1: Evaluate impact of spinal stimulation on spasticity and locomotor function. Aim 2: Investigate participant perceptions of spinal stimulation. The investigators will be using a cross-over design study to compare intensive training only to intensive training combined with spinal stimulation. After an initial baseline period of up to 4 weeks (Phase I). Participants will have their first intervention phase of the study (Phase II). This will involve either intensive training only (Condition A) or intensive training combined with spinal stimulation (Condition B). This will be followed by a washout period with no intervention (Phase III) and then the second intervention phase (Phase IV). The second intervention phase will involve either Condition A or Condition B, whichever the participants did not received during Phase II. Phases II-IV will each last up to 8 weeks. After the intervention period is complete, the participant will be asked to come for follow-up visits up to 3 months after the intervention phases are completed (Phase V).
