Upper limb recovery is not predicted by the initial severity of paralysis and the parameters reflecting the integrity of the corticospinal tract (e.g. motor evoked potential, fractional anisotropy in diffusion tensor imaging). Although the inhibition of the contralesional hemisphere is known to be beneficial for the upper limb recovery after stroke in previous studies, this is not proven in the severely paralyzed upper limb. And the studies using the noninvasive stimulation in subacute stroke is lack. In addition, the role of contralesional (unaffected) hemisphere is known to be playing the important role in severe stroke. In this randomized, double-blind, sham-controlled studies, the patients with subacute stroke (<3 months after stroke onset), severe paralysis of the upper limb with poor prognosis (poor motor score and no response of motor evoked potential recorded in the extensor carpi radialis muscle) will be recruited. Interventional group will receive the 25 mins of anodal transcranial direct current stimulation (tDCS) over the contralesional premotor area plus 25 mins of robotic arm training per session for 10 sessions in 2 weeks. Control group will receive the same treatment except for sham tDCS instead of anodal tDCS over the contralesional premotor area. Functional outcome will be measured before and after the intervention (baseline, immediately after the intervention and 1 month after the intervention). Cortical activation pattern will be measured by the electroencephalography (EEG) at baseline and immediately after the intervention.
This study compare the effectiveness of 2 rehabilitation programmes that use (1) MT with Bilateral TENS (Bi-TENS), (2) sham-MT with Bi-TENS (Bi-TENS), respectively, in addition to conventional rehabilitation of standardized upper limb training, in improving upper limb motor functions, activities of daily living, community integration, and quality of life in patients with stroke.
This study aimed to investigate the effects of dual-task training with exergame and treadmill on executive function and dual-task performance in individuals with PD and stroke and discuss the correlation between the change values of executive function and dual-task performance after training. Besides, investigate cortical activation after training.
This study aims to evaluate the effectiveness of concurrent mirror therapy (MT) and transcutaneous electrical nerve stimulation (TENS) in augmenting the efficacy of the lower limb task-oriented training in people with stroke. It is hypothesize that MT combined with TENS would be superior to sham-mirror therapy with TENS, or MT with placebo-TENS, or control training only in improving lower limb motor functions and walking ability in people with stroke when combined with the lower limb task-oriented training.
Fragile brain is the most common phenomenon seen in the patients undergoing CEA. The patients with fragile brain have a high incidence of postoperative brain dysfunction. This study intends to apply EEG monitoring (Sedline) to CEA to investigate whether EEG monitoring can reduce the incidence of postoperative neurological complications in CEA patients and improve their prognosis. 220 patients with CEA were randomly divided into 2 groups. Group S [Sedline monitoring + Transcranial Doppler (TCD) + regional cerebral oxygen saturation (rS02)，n=110] and group C [Bispectral index (BIS)/Sedline monitoring + TCD +rSO2,n=110], recording intraoperative and postoperative conditions, neuropsychology scale assessment, blood examination and imaging examination. The incidence of postoperative neurological complications was compared between the two groups.
The main objective of this multi-site project is to compare the effects of 12 weeks of HIIT vs. MICT on brain plasticity. The effects of HIIT vs. MICT on cardiovascular health, psychosocial predictors of physical activity and motor function will also be compared. HIIT and MICT will be delivered through a whole-body exercise paradigm using a recumbent stepper that requires arm and leg forces. Outcomes will be assessed at baseline (T0, 0 weeks), at the end of the intervention (T1, 12 weeks) and at 8-week follow-up (T2, 20 weeks).
There is currently a shortage of organ in France, for patients with chronic diseases who are on the waiting list for an organ. The first source of organ donor in France is patients with brain death. 58% of patients in brain death are patients with a severe stroke ( ischemic or hemorrhagic). In order to identify which patient with a severe stroke and with unfavorable prognosis who can evolve to brain death, we have conducted a retrospective study in Lorrain, in France, and we have built a predictive score of brain death in these patients. It is important to validate this predictive score in a prospective study on a greater scale than the first study.
Atrial fibrillation (AF) is the most common cardiac arrhythmia encountered in clinical practice. This arrhythmia is responsible for 15% of strokes and more than 30% of strokes on people over 65 years. According to studies, 30 to 40% of isolated atrial fibrillations could be familial. Atrial fibrillation has significant genetic heterogeneity. About 40 genes have been identified as potentially involved. Studies have identified genes common to the risk of atrial fibrillation and stroke. Despite the pathophysiology of atrial fibrillation has been intensively and extensively studied for almost a century, there are still many questions. The pathophysiology is not sufficiently understood to allow finding more effective therapies. It is necessary to identify genetic determinants and thus potentially new pharmacological targets more adapted. The establishment of a biological database will test hypotheses concerning the genetic origin and thromboembolic process of atrial fibrillation and associated stroke.
The primary outcome of this study is to determine the quantitative increase in connectivity, as measured by fMRI brain and calculated as a percent increase from baseline in patients with ischemic stroke. Eligible patients will receive a listening session of music or spoken word listening, 30 days to 5 years following ischemic stroke. Assessments will include modified Rankin Scale, National Institute of Health Stroke Scale, functional Magnetic Resonance Imaging, motor function tests, and neuropsychological evaluations. Assessments occur at baseline, day 45, and day 90 after starting listening sessions.
