This is a Phase II, randomized, double-blinded, placebo-controlled study for subjects with evidence of PSCI.
Invasive intracranial pressure (ICP) monitoring is highly effective, but involves risks. HS-1000 measures ICP non-invasively by assessing the acoustic properties of the patient's head. HS-1000 device, a proprietary non-invasive ICP monitor, is expected to safely and accurately monitor ICP with minimal discomfort to patients, and provide information about normal or elevated ICP levels to the physicians.
A prospective pilot study to evaluate the recanalization and safety of mechanical thrombectomy through a cerebral angiogram in patients with stroke symptoms last seen normal between 8 - 24 hours.
Autologous human umbilical cord blood (hUCB) stored at Cord Blood Registry will be given to children who have suffered from a Perinatal Arterial Ischemic Stroke. The aim is to determine if hUCB infusion is safe, if late functional outcome is improved, if hUCB treatment improves physiologic response in the child's SSEP & EEG, and the effect of hUCB infusion in altering anatomic findings on MRI.
The past 10 years of research in post stroke patients have shown certain types of rehabilitation can help neuronal plasticity of the brain. Transcranial magnetic stimulation (TMS) can be used to monitor this plasticity by mapping the brain's function (measuring brain activity). Recent research suggests that TMS can be used for both prognosis (determining future function) and to determine what type of rehabilitation therapy will work best after stroke. The purposes of this research study are to: 1) determine changes in cerebellar activity after motor cortical stroke 2) compare changes in recovery of motor function with changes in cerebellar - motor cortex connections; 3) determine the ability of TMS to "predict" functional outcome after stroke. The primary hypotheses are: 1) functional recovery will be correlated with TMS changes (as measure of motor threshold (MT), intracortical inhibition, cerebellar cerebral inhibition (CBI), motor evoked potentials (MEPs) and recruitment curves; 2) baseline TMS will predict future functional outcomes.
Patients with severe ischemic and hemorrhagic strokes, who require mechanical ventilation, have a particularly bad prognosis. If they require long-term ventilation, their orotracheal tube needs to be, like in any other intensive care patient, replaced by a shorter tracheal tube below the larynx. This so called tracheostomy might be associated with advantages such as less demand of narcotics and pain killers, less lesions in mouth and larynx, better mouth hygiene, safer airway, more patient comfort and earlier mobilisation. The best timepoint for tracheostomy in stroke, however, is not known. Preliminary data from a pilot study of early tracheostomy in patients with hemorrhagic or ischemic stroke suggest that such patients may also have improved survival and long-term functional outcomes, but a large, multicenter clinical trial is needed to confirm these findings.
This study is to investigate changes in brain activities in acute stroke patients , and to correlate findings with clinical outcome measures. Another aim of the study is to investigate whether transcranial direct current stimulation (tDCS) could improve motor function in subjects with poor brain activity after stroke. The brain activity will be measured by single and paired pulse TMS (transcranial magnetic stimulation). The study hypothesizes that: 1. The neural mechanisms employed in patients who have different response to TMS stimulation are different. It is hypothesized that patients with no response upon TMS stimulation might have poorer motor function outcome, compared with patients with response upon TMS stimulation. 2. The result of clinical outcome measures is related with TMS measurement. 3. tDCS intervention is beneficial to subjects with poor brain activity. Clinical outcome measures will include a battery of upper limb motor tests such as upper extremity component of the Fugl-Meyer Assessment, Modified Ashworth scale for spasticity, box and block test, and manual muscle testing. Clinical outcome and TMS measurement will be assessed at within 2 weeks, 4-6 weeks and at 6 months post-stroke.
The investigators have developed the kinect-based upper extremity rehabilitation program and designed this protocol to prove the efficacy of this program. In brief, subacute stroke patients allocated to intervention group will receive the kinect based-rehabilitation program plus conventional occupational therapy and patients allocated to control group will receive the sham virtual rehabilitation plus conventional occupational therapy, for 10 days. 20 patients with subacute stroke will be allocated into each group and after completing the 10 days intervention, they will be assessed by using objective assessment tools for upper extremity function.
This research is a Randomized, double-blind, placebo-controlled, multicenter clinical study. Chinese subjects with Ischemic Stroke.
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.
