Filter by:Because atrial fibrillation occurs frequently in heart surgery patients, our overall hypothesis is that systematic closing the left atrial appendage during surgery will reduce cerebral embolism coming from the thrombus formation in the left atrium. The specific hypothesis which sought tested is that closure of the left atrial appendage in connection with elective CABG and / or valve surgery will lead to fewer strokes and micro cerebral infarcts measured by MRI.
Stroke is the leading cause of physical disability due to the presence of spasticity. Different needling techniques, including Botulinum Toxin A are proposed for management of spasticity; however results are conflicting. The presence of spasticity in the upper extremity implies several impairments for daily life activities. No study has investigated the effects of deep dry needling inserted into the targeted spastic musculature of the shoulder region in patients who had suffered a stroke. The investigators will conduct a randomized controlled trial investigating the effects of the inclusion of deep dry needling into a rehabilitation program over the musculature of the shoulder region, pressure pain hyperalgesia and range of motion in individuals with chronic stroke. The investigators hypothesize that patients receiving dry needling into the spastic shoulder musculature would exhibit greater improvements in spasticity, pressure sensitivity and range of motion than those who will not receive the intervention.
A longitudinal study of function and participation in patients with stroke: An integrated brain imaging and biomechanical analysis
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.
There is few information about the association between supraventricular arrhythmia different from atrial fibrillation (AF) or atrial Flutter and the risk of stroke. In this study the investigators hypothesized that the presence of atrial tachycardia would lead to atrial fibrillation and recurrent stroke in patients hospitalized for cryptogenic stroke. The investigators study the association of atrial tachycardia (AT), defined as four or more consecutive premature atrial beats, and AF, recurrent stroke and cardiovascular mortality in 192 consecutive patients hospitalized because of cryptogenic stroke. The follow-up was 12 months for all population
The hemiparesis is one of the most important sequelae of stroke, and generally have greater impairment in the upper limb (UL) contralateral to the brain injury. To obtain greater amount of use and most affected UL movement quality, studies have described as a rehabilitation technique constraint Induced Therapy (CIT). The objectives of this study will evaluate the effect of CIT in severe hemiparetics patients in the quantity and quality of movement UL and grip strength, and the relation between the scapular kinematics and trunk with the quality of movement measured clinically. Randomized crossover study with systematic reviews in AB mode, where A is the baseline to the evaluation of the period of 2 weeks without any intervention and B, the two-week period with intervention. One group will start with the intervention period (BA) and the other group with the period without intervention (AB). The intervention will be for 3 hours / day, 5x / week for two weeks and use of wrist and fingers restriction UL unaffected. To evaluate the quality and quantity of UL use in real environment will be used to Motor Activity Log (MAL), to quantify the motor skill the Wolf Motor Function Test (WMFT), the 3D movement of the scapula and trunk during arm elevation and functional activities of the UL will be measured by the electromagnetic tracking system and grip strength by hand dynamometer.
Early after stroke, patients often have significant motor impairment and sensory deficit. Evidence has demonstrated heightened plasticity and significant recovery in the acute phase (first months) post stroke but there has been a lack of effective and practical protocols and devices for early intensive sensorimotor therapy.This research study will conduct a randomized clinical trial of an intensive motor-sensory rehabilitation on patients with acute stroke using a wearable rehabilitation robot. The primary aims are to facilitate sensorimotor recovery, reduce ankle impairments, and improve balance and gait functions. This clinical trial will be conducted on the Study and Control groups of acute stroke survivors.
Stroke is the second most frequent causes of mortality in the word after cardiovascular disease and the most frequent cause of disability. The majority of strokes are ischemic (87%). Ischemic stroke may benefit from efficient therapy if the delay from stroke onset not exceeds 4H30 (intra-venous thrombolysis). In case of irreversible cerebral lesion, the long term functional recovery is largely dependent from the ability of the brain to reorganize. Conventional magnetic resonance imaging represents the most sensitive tool to diagnose stroke at the acute phase. However, up to now, no imaging tool is available to determine the time of stroke onset. Moreover, no imaging tool is available to precisely quantify the functional and structural plasticity mechanisms occurring after stroke. The main objective of the present study is to test the accuracy of sodium MRI to determine the time of stroke onset. The secondary objectives of the study are to determine the ability of non-conventional MRI techniques to quantify the degree of tissue damage and brain reorganization after stroke. Thirty patients will be included during the first 24 hours after stroke onset. Multimodal MRI (including perfusion MRI, sodium MRI, resting-state functional MRI, high resolution anatomical MRI) and clinical evaluation will be carried on at the inclusion, after 24 hours, at 3 months and at 12 months.
The aim of this study is to analyze and describe rehabilitation pathways of stroke patients in a region of North Norway and Central Denmark Region in relation to how patients perceive quality of life, health and functioning one year post stroke. The study will consist of 1) Translate, cross-cultural adapt and validate a stroke-specific health-related questionnaire 2) Describe the level of quality of life and rehabilitation pathway in the two countries 3) In-depth interviews of a smaller group of patients for a more complex understanding The study is part of a larger prospective observational multicenter-study of two patient cohorts with stroke.
The aim of the study is to determine the feasibility of the portable version of the YouGrabber® system in children with central motor disorders.
