Filter by:This will be a randomized double blind placebo-controlled pilot study using a repeated measures design in which participants with acute ischemic stroke and intracranial atherosclerotic disease are randomized to either drug or placebo.
The main objective of the PROOF trial is to investigate efficacy and safety of normobaric hyperoxygenation (NBHO) as a neuroprotective treatment in patients with acute ischemic stroke due to large vessel occlusion likely to receive endovascular mechanical thrombectomy (TBY) in a randomized controlled clinical phase IIb trial.
Impaired motor function is common after stroke. Individuals with stroke often exhibit synergic pattern that disturb daily function. It is crucial to identify the movement impairment in the clinical settings. Upright Motor Control Test (UMCT) is one of the tests developed to assess the selective movement control and functional strength in people with central nervous disorders. It can be used to reflect the impairment of motor function and evaluate changes of performance after treatment. Yet is little to know the clinimetrics of the UMCT on clinical utility. To date, only few researches explore that UMCT has some construct and criterion validity. Therefore, this study aims to 1) establish the inter-rater reliability to administer the UMCT. 2) explore the correlation between the Fugl-Meyer Assessment of Motor Recovery after Stroke (FMA) and UMCT. 3). investigate whether the UMCT is able to predict the walking ability in patients with stroke.
The study will enroll 5 individuals post-stroke to examine the feasibility and efficacy of a high frequency repetitive transcranial magnetic stimulation (rTMS) combined with body weight supported treadmill training.
Functional recovery is one of the main issues in the management of stroke and there are various ways in rehabilitation to promote this recovery. Verticalization is a technique whose benefits have been widely demonstrated, particularly in neurology. Although commonly used in the rehabilitation of stroke, evidence is still lacking as to its impact in this specific care. Verticalization is underutilized in two situations: in the hyper acute phase as well as in elderly and very deficient patients. It has, however, been shown that the precocity of the treatment allows a better functional recovery. Similarly, the re-education of the elderly is also debated since it has long been mentioned that age was a factor of poor prognosis, the objectives are sometimes underestimated. However, several studies have shown that with the same rehabilitation, elderly patients recover as much as younger patients. The differences found are at least in part due to "less rehabilitation" of older stroke patients. The different existing data lead us to the hypothesis that the verticalization of the elderly hemiplegic patient in acute phase would allow a better functional recovery.
The purpose of the ImpACT-24col sub-study is to explore effect of SPG stimulation on the augmentation of collateral blood flow and to relate it to the subject's cerebral blood flow status, the extent of the collateral vessel potency prior to the stimulation and the relation of the vessel occlusion site to the vasodilatory effect by using digital subtraction angiography (DSA), the gold standard imaging technique to demonstrate collateral blood flow dynamics. The results of this study will further promote the knowledge towards optimization of SPG stimulation to treat acute ischemic stroke patients.
The study procedure of simultaneous VFSS and DDS measurement will be completed in one day and the subject will be followed within 2 business days after the study procedure to monitor for adverse events.
Despite the wide-spread use of botulinum toxin (BT) to treat spasticity (increased muscle tone) in central neurological disease, evidence-based guidance on dosing, dilution, and injection technique is limited. The wide-spread use of BT in spasticity management, expense of these agents, and detrimental impact from movement into non-injected muscles mandates a better understanding of BT movement within muscles. A proof-of-concept paper written by investigators at Weill Cornell Medicine introduced a non-invasive MRI approach with "voxel thresholds" that was able to detect intramuscular effects of BT at 2 and 3 months post-injection of BT. The purpose of the current set of studies is to refine this MRI technique to better visualize the movement of botulinum toxin through muscle. In addition, the investigators plan to explore, using the imaging technique, how spastic muscle and differing dilutions affect BT movement in an effort to support the development of better research techniques to study toxin movement in human muscle.
To investigate acute metabolic and cardiorespiratory responses during overground gait training with a wearable exoskeleton in persons after stroke
After intravenous thrombolysis, the overall recanalization rate is 46%, and recclusion after initial recanalization occurs in 14-34%. In the MR TEA, the investigators compared the effects of administration of tirofiban in acute ischemic stroke patients treated with intravenous alteplase thrombolysis with alteplase alone.
