Filter by:Post-stroke fatigue is common and negatively influences post-stroke recovery. Today, there is insufficient evidence how to treatment post-stroke fatigue. Our objective is to investigate if a structured cardiorespiratory interval training program added to the early supported discharge (ESD)-service results in relieved post-stroke fatigue and increased oxygen uptake. This is a 1:1 prospective randomized open- label trial(Two-centre study) with blinded evaluators (PROBE-design) of 50 participants referred to ESD with study start at 4 (±1) weeks after discharge from the stroke unit. The intervention group (N=25) receives a structured cardiorespiratory interval training program on ergometer cycle, 30-40 minutes, 3 days a week for 8 weeks. The cardiorespiratory interval training program comprises of 4x4 minute interval, at 70 to 80% of peak heart rate, interrupted by 3 minutes active recovery. The control group (N=25) receives usual ESD care. The primary outcome will be a shift in the Swedish Fatigue Assessment Scale before intervention (baseline) versus 8 weeks months after start of intervention in the intervention and control groups. Secondary outcomes include cardiorespiratory fitness, compliance, adherence and adverse events.
People with central nervous system disorders such as spinal cord injury, stroke, cerebral palsy, Parkinson's disease, multiple sclerosis, etc… often have impaired lower extremity function that limits activities of daily life and independence. Different body-weight support systems have been developed to facilitate the rehabilitation process by compensating for the user's residual abilities. However, studies on weight-supported gait training on a treadmill have failed to show superiority over conventional rehabilitation programs for spinal cord injury and stroke. A recent study by the group around Grégoire Courtine showed that body-weight support systems that provide assistance only in the vertical direction disrupt the production of gait and balance, suggesting that current practices may even be detrimental for relearning to walk. For the past year, the Clinique Romande de Réadaptation (CRR) worked together with the G-Lab at EPFL and G-Therapeutics on a new robot platform specifically developed to provide adjustable trunk support along four independent degrees of freedom (LEAP). The investigators were able to draw on their long-term experience, which consists of different body weight support training systems for stroke and spinal cord injury. This knowledge, combined with the input of our therapists and physicians and the specific requirements for people with neurological/musculoskeletal disorders, has resulted in a design that can provide adjustable bodyweight support during over-ground locomotion, treadmill, stairs training, standing up and sitting down and for support during the training of activities of daily living. The scope of this study is to examine how well the robot can be used for rehabilitation therapy in everyday clinical practice. This includes, among other things, technical aspects such as the handling of the hardware, the adaptability of the robot to the patient, and the safety during operation (such as the fall prevention). Various patient-specific aspects will also be evaluated e.g. comfort, positioning, or motivation of the patient. This study also aims to evaluate the software with the various support modes, operating options, and the user interface of the LEAP.
The cerebellum is known to be strongly implicated in the functional reorganization of motor networks in stroke patients, especially for gait an balance functions. Repetitive transcranial magnetic stimulation of the cerebellum can be used to enhance these adaptive processes in stroke recovery. In this randomized, double blind, sham-controlled trial we aim to investigate the efficacy and safety of cerebellar intermittent theta burst stimulation coupled with intensive physical therapy in promoting gait recovery in hemiparetic patients due to recent stroke in the territory of the contralateral middle cerebral artery
Ischemic stroke is accompanied by a three to four hundred percent increase in the brain's extracellular fluid (ECF) and cerebrospinal fluid (CSF) concentration of glutamate, which diffuses and damages surrounding neurons. In this study we tested our hypothesis that blood glutamate levels can be reduced by hemofiltration, resulting in increased extracellular clearance of glutamate and attenuated neurodegeneration, and that decreased blood glutamate levels can provide significant neuroprotection against stroke-associated neurodegeneration, dysfunction and death. Our primary outcome of interest was to assess safety of hemofiltration in acute ischemic stroke patients.
The investigators will conduct an epidemiological analysis of data from the Women's Health Initiative to investigate the prospective association between chocolate intake and the risk of heart disease and stroke.
Following a stroke , 55% of the patients do not recover any traction of the upper limb and 30% a residual motricity not allowing a functional grip. For this last group of patients, there are major therapeutic issues to restore a functional grip. The aim of the study is to relieved the spastic cocontractions before and after usual injection of botulinum toxin A at stroke patient.
The TCSD Study will identify disparities in transitions of stroke care and key factors associated with effective transitions of care through structured telephone interviews to evaluate medication adherence, healthy lifestyle, utilization of rehabilitation interventions and medical follow-up 30 days after hospital discharge to home in 2,400 participants across 12 comprehensive stroke centers (CSC) in Florida. A novel Transitions of Stroke Care Performance Index (TOSC PI) correlated with 90-day rehospitalization will be derived and validated.
Stroke is one of the leading causes of serious long-term impairment. According to the estimates, 12,500 people suffer a new or recurrent ischemic stroke in Chile annually, which shows the magnitude of the problem. Motor impairment of the upper limb (UL) stands out as the principal sequel after a CVA (50% of the patients experience it), and the Constraint-Induced Movement Therapy (CIMT) is the rehabilitation approach that shows more scientific evidence today. Even though patients reach certain recuperation levels through this approach, results are still insufficient since 50-80% of the patients continue having upper limb motor impairment after completing standard rehabilitation. Because of this, it is pertinent to conduct research to explore new rehabilitation strategies to reduce the impairment indexes and to provide information for decision making based on evidence. Recent studies on functional neuroimaging propose that there is an abnormal balance in the motor cortex excitability after stroke - relative under-excitability in the affected hemisphere and over-excitability in the unaffected hemisphere (with the consequent inhibitory influence on ipsilesional regions) in stroke patient with moderate motor impairment. This imbalance in the hemispheres function would limit the possibilities of a greater recovery. Then, in order to reestablish brain balance, the investigators proposed that the early introduction of noninvasive techniques of brain stimulation, such as tDCS, to the motor rehabilitation training could promote improvement of upper limb function in patients with stroke. However, we lack studies that confirm the benefits of using these techniques, define the most appropriate protocols, and determine what patients and under which evolving stages would be the best candidates for treatment. This study aims to "compare the effectiveness of seven days of bi-hemispheric tDCS, both active and sham, combined with modified CIMT (mCIMT) in the motor and functional recovery of the hemiparetic upper limb in hospitalized patients with subacute unihemispheric stroke at Hospital Clínico de la Universidad de Chile and Hospital San José". This comparison responds to the hypothesis that patients who receive bi-hemispheric and active tDCS combined with mCIMT (experimental group) get at least 30% more recovery of the paretic upper limb compared to the control group who receive sham bi-hemispheric tDCS plus mCIMT after a protocol of seven days treatment.
This study aims to identify factors influencing the time span and success of reperfusion after a mechanical thrombectomy in the acute phase of cerebral infarction, and in particular the effect of intra-venous thrombolysis.
About 35,000 people each year in the UK have a type of stroke, called 'lacunar' or 'small vessel' stroke, which is different to other common types of stroke and for which there is no proven treatment. It is thought that small vessel stroke is caused by damage to the lining of the tiny blood vessels deep inside the brain that stops them functioning normally. This not only causes stroke but, perhaps more importantly, causes problems with thinking and walking, possibly causing up to 45% of all dementias either on its own, or mixed with Alzheimer's disease (about 350,000 patients in the UK). Some drugs that are commonly used in other blood vessel diseases may help improve small vessel function and prevent worsening of brain damage. One drug (cilostazol) has been tested in patients with stroke in the Asia Pacific countries but not on dementia; the other drug (isosorbide mononitrate) is widely used in the UK for heart disease but not stroke. The investigators want to set up a clinical trial to test if the study methods are practical so that patients and trial centres can follow the procedures, and to confirm how many patients have more stroke-like symptoms or experience worsening of their thinking skills. This information is needed to be sure that a very large clinical trial to find out if these drugs can prevent worsening of small vessel disease will be possible.
