Filter by:The robot assisted therapy is one of the new developed technologies for recovery after stroke. This study aimed to evaluating the effect of robotic gait therapy for motor recovery after stroke.
The present pilot study is designed to assess the extent to which BOTOX and MYOBLOC cause muscle atrophy in spastic patients. The primary objective is to assess whether there is statistically significant difference in muscle atrophy between the two groups over a one year period.
Purpose: To investigate the different sound spectrum of carotid arteries and to analyze its relationship to the vessel disease, and to build a new biomarker about vascular disorder. Methods: To record the carotid phonoangiography with digital stereoscopy and analysis the spectrum with different algorithm such as FFT, wavelet, entropy, complexity, and HHT. The results will be correlated and comparison to the finding in clinical, carotid Doppler and duplex, CTA, MR, and catheter angiography. Statistics: The significance of difference between parameters was computed using t-tests or paired t-test etc. A p value <0.05 is defined as significant.
The purpose of this study is to determine the effectiveness of training hand movement using FINGER robot after stroke. FINGER is a robot that measures finger movements and allows users to play computer games using those movements.
The study will use MRI brain imaging to identify brain changes associated in stroke patients after they receive speech-language treatment for their speech difficulties.
Strokes are very common in the United States and occur more in the elderly. The number of strokes is likely to double in the next 50 years. Many stroke survivors are sedentary and have a poor dietary intake, which results in abnormalities in fuel utilization (eg carbohydrate versus fat). This study will examine the effects of dietary modification and treadmill training on fuel utilization and physical function. We will study skeletal muscle oxidative stress in chronic stroke patients and the ability to employ dietary modification and exercise training to reverse these abnormalities in this ethnically diverse population.
Rationale Acute ischemic stroke due to atrial fibrillation (AF) carries a high risk for early recurrence. In acute stage, guidelines recommend aspirin, but do not recommend anticoagulation due to the increased risk of intracranial bleeding. Since, aspirin has a limited efficacy of preventing recurrent stroke in AF, expert consensus suggests early anticoagulation in non-severe stroke with AF. The current practice for acute ischemic stroke patients with AF is delayed warfarin administration with aspirin use for non-minor stroke or immediate warfarin administration (sometimes with heparin bridging) for minor stroke. However, conventional anticoagulation with warfarin in acute ischemic stroke with AF has the following limitations: 1) risk of intracranial bleeding particularly in acute stage, 2) delayed action and transient paradoxical thrombogenic tendency due to the inhibition of protein C, resulting in the risk of early recurrent embolic stroke, and 3) prolongation of hospitalization waiting for full anticoagulation. In contrast, as compared to warfarin, rivaroxaban is advantageous for reduced risk of intracranial bleeding and immediate anticoagulation efficacy. Goal The current trial will examine whether early initiation (within 5 days from stroke onset) of rivaroxaban as compared to conventional warfarin would reduce intracranial bleeding, recurrent embolic stroke, and hospital stay in patients with acute ischemic stroke due to AF.
The purpose of the Trevo® Retriever Registry is to collect real world performance data of the Trevo Retriever which is intended to restore blood flow in the neurovasculature by removing thrombus in patients experiencing ischemic stroke.
Intravenous (IV) tissue plasminogen activator (tPA) is the only FDA-approved therapy for treatment of acute ischemic stroke. In the United States, IV tPA is typically administered in the Emergency Department (ED) for patients presenting with acute ischemic stroke within 4.5 hours of symptom onset. It is current practice that post-tPA patients are monitored in an intensive care unit or intensive care unit (ICU)-like setting for at least 24 hours, in part due to frequent vital sign and neurological monitoring that is currently the standard of care. However, rigorous evidence to support this practice is largely lacking. In a retrospective analysis of 153 patients receiving IV tPA at Johns Hopkins Hospital (JHH) and Johns Hopkins Bayview Medical Center (JHBMC), investigators have shown that most patients who have ICU needs in the first 24 hours after tPA administration develop such needs by the end of the tPA infusion. Patients without ICU needs by the end of the tPA infusion, do not require further ICU resources if patients' presenting NIH Stroke Scale (NIHSS) is below 10. This study is a prospective clinical trial that aims at establishing the first proof-of-concept and feasibility of whether patients with a low NIHSS (NIHSS 9 or less) and that do not need ICU care by the end of the tPA infusion, can be monitored safely in a non-ICU setting with a novel monitoring protocol. Identifying post-tPA patients who can be safely monitored in a non-ICU environment may improve cost-effective utilization of ICU resources and reduce the length of hospitalization for stroke patients.
Stroke is one of the leading causes of death and disability worldwide. More than 85% of strokes are due to blood vessel occlusion resulting in partial destruction of the brain parenchyma. Current protocols try to re-establish blood circulation as soon as possible through chemical and/or mechanical interventions but new strategies are needed. Periodic acceleration (pGz) is a non-invasive method consisting in the application of a rocking movement to the patient that ultimately will induce the release of beneficial chemicals from the vascular endothelium (the cells lining the inside of the blood vessels). Application of pGz in an animal model of stroke resulted in a dramatic reduction of associated brain damage. This trial will investigate whether stroke patients exposed to pGz experiment significantly higher recovery than patients that remained static during their treatment.
