Filter by:Even if it is a daily questioning for the stroke physician, no concrete recommendation exists regarding the time-point of the mobilization of stroke patients. In this study, we will compare two mobilisation strategies: early versus delayed "verticalisation". 400 ischemic stroke patients will be included in this prospective randomized controlled trial, equally distributed in two groups. In the early mobilisation procedure the patient is allowed to go and sit outside of the bed the day after the stroke onset, whereas in the other arm, this procedure is delayed to the third day after stroke onset. The outcome in both groups will be assessed by the modified Rankin Scale at 3 months, which is commonly used in stroke study to investigate the functional outcome of the patients.
Evaluation of the sensitivity and specificity of PMSI to identify the burden of stroke in France,from 2500 cases
Patients with cerebral hemorrhage (ICH) have a high risk of venous thromboembolism. Intermittent pneumatic compression combined with elastic stockings have been shown to be superior to elastic stockings alone in reducing the rate of asymptomatic deep vein thrombosis after ICH in a randomized trial (4.7% vs. 15.9%). Graduated compression stockings alone are ineffective in preventing deep vein thrombosis in patients with ischemic or hemorrhagic stroke. Less clear is the role of anticoagulation in the prevention of venous thromboembolism in patients with ICH because the use of anticoagulants may cause an enlargement of the hematoma. In a multicenter, randomized trial, the investigators will assess the efficacy and safety of enoxaparin in the prevention of venous thromboembolism in patients with spontaneous intracerebral hemorrhage. Enoxaparin (40 mg once daily) or standard therapy (graduated compression stockings and/or intermittent pneumatic compression and/or early mobilization) will be given subcutaneously for not less than 10 days beginning after 72 hours from stroke onset.
Mild hypothermia improves outcome in patients with global cerebral ischemia after cardiac arrest. Hypothermia seems promising also in other acute hypoxic-ischemic or in brain swelling associated cerebrovascular disease. The narrow-time-frame is a major issue ("time is brain"). To provide immediate cooling without delay, easy to use, mobile and effective methods are needed. Cold infusions (4 °C) are an accepted standard worldwide. The RhinoChill (BeneChill, USA) is a new device. A comparison of these two induction methods has never been done before. Neither was the effect of cold infusions on brain-temperature measured. For the first time iCOOL 1 compares feasibility, safety and efficacy of the two methods.
Chronic stroke patients (>6 months) fulfilling including criteria were trained during 3 months. The physical training program was based on walking.
The purpose of this research study is to evaluate the effectiveness of functional electrical stimulation (FES) provided by an implanted pulse generator (IPG) in correcting hip, knee and ankle function to improve walking in people with partial paralysis.
Stroke is a leading cause of morbidity in the United States but identification of treatment strategies to improve outcome is limited by the incomplete understanding of the mechanisms of recovery. Motor cortex (M1) reorganization plays a major-role in the recovery of motor deficits post-stroke; hence the importance for further development of rehabilitative strategies that utilize this potential for recovery. In Specific Aim 1, investigators will determine if repeated exposure to training combined with Hebbian-type M1 stimulation enhances functional M1 reorganization in lesioned M1 of stroke patients. In Specific Aim 2, investigators will determine if repeated exposure to training combined with Hebbian-type M1 stimulation enhances structural cortical reorganization in lesioned M1 of stroke patients and to explore whether these structural changes are related to the training induced functional cortical reorganization. The overall goal of this project is to determine the effect of Hebbian- type stimulation on both, functional and structural brain reorganization, thereby obtaining indirect evidence for the neuronal substrate underlying training related improvement and maintenance of motor function in stroke patients. This knowledge may have a substantial positive impact on treatment for stroke patients that may significantly improve recovery and could move the field of neuro-rehabilitation forward.
Community ambulation is a highly complex skill requiring the ability to adapt to increased environmental complexity and perform multiple tasks simultaneously. Deficits in dual-tasking may severely compromise the ability to participate fully in community living. Unfortunately, current rehabilitation practice for stroke fails to adequately address dual-task limitations; individuals with stroke continue to exhibit clinically significant dual-task costs on gait at discharge. As a result, many stroke survivors are living in the community with residual deficits that may increase disability in the real world and lead to falls with devastating consequences. To address this issue, the proposed study investigates the efficacy of dual-task gait training on attention allocation and locomotor performance in community-dwelling stroke survivors. Because walking in the real world often requires time-critical tasks and obstacle avoidance, the investigators will test the impact of dual-task gait training on cognitive-motor interference during walking at preferred speed and at maximal speed (Aim 1), and on locomotor control during obstacle negotiation (Aim 2). The investigators will also evaluate the effects of the intervention on community reintegration and participation (Aim 3).
Many patients retain upper-limb motor impairment following stroke. Most conventional rehabilitation techniques are aimed to improve motor intentional movement by repeated exercises. These techniques require attentional load and are responsible for significant fatigue that probably represents a limiting factor. Alternatively, the automatic control of action is now well documented. A rehabilitation method based on this principle could allow recovery of more natural movements. Hypothesis: Stimulating automatic motricity improves upper-limb motor skills compared with a rehabilitation technique based on intentional movements.
Stroke is one of the major causes not only of mortality, but of disease burden worldwide, because of residual disability and cognitive decline. Although blood pressure lowering has been clearly shown to be the most effective means for primary and secondary prevention of stroke, the systolic blood pressure (SBP) levels to achieve by treatment in order to optimize prevention results are unknown, and whether SBP levels lower than those usually recommended are accompanied by further or reduced benefits is undecided yet. Likewise, while low-density lipoprotein cholesterol (LDL-C) lowering by statins has been shown to be associated with primary and secondary stroke prevention, whether more intense lowering is or is not of further benefit is unknown. The Stroke in Hypertension Optimal Treatment Trial (ESH-CHL-SHOT) is a factorial 3 x 2 arm, multicenter, randomized clinical trial designed to test the hypothesis that in elderly patients at high risk of recurrent stroke (previous recent stroke or TIA) antihypertensive treatment programs aimed at reducing SBP to the usually recommended values (< 145 to 135 mmHg), to a lower goal (< 135 to 125 mmHg) or to even lower values (< 125 mmHg) will result in progressively greater reductions in recurrent stroke, incidence of cardiovascular outcomes and cognitive decline. Parallely, the preventive efficacy of more and less intense LDL-C reductions will be tested on the same outcomes.
