Filter by:MOCSS study is a multicenter prospective clinical cohort study. The purpose of the MOCSS study is to investigate whether there is a correlation between the preoperative cerebral small vessel disease and the incidence of covert stroke after non-cardiac surgery. Cerebral small vessel disease (CSVD) and covert stroke will be diagnosed using multimodal MRI. This study will also investigate whether preoperative CSVD and postoperative covert stroke are related to postoperative cognitive dysfunction and delirium.
Stroke is the second leading global cause of mortality counting for 6.5 million deaths per annum. The global prevalence of stroke is increasing with an estimated prevalence of 33 million per year, affecting 1 out of 6 individuals during their lifetime. The international data suggests the overall economic burden in Asia is projected to be increased to 1.3 Billion by 2050. Therefore, the appropriate and timely stroke intervention is required to save healthcare costs and reduce the burden of the disease. Studies have reported the effectiveness of VR intervention not only in cognitive abilities but it has found to be simultaneously effective in improving other domains as attention and coordination with motor retraining. VR combined with a newly developed concept of motor priming has shown encouraging results in improving motor control and task execution in stroke patients. Further studies are needed to analyze the impact of motor priming with VR in stroke patients on varied neurological domains; hence the present study aims to investigate the impact of VR based motor priming on sensorimotor, functional and cognitive outcomes among sub-acute stroke patients rehabilitation.
For the clinical benefit of intravenous thrombolysis "IVT" or intra-arterial thrombectomy "IAT" time is the most crucial factor. Reducing the time between stroke onset en treatment is therefore a major goal. Since IAT is only suitable for stroke due to large anterior vessel occlusion "LAVO" which is only performed in specialized comprehensive stroke centers "CSC", triage of LAVO-patients in the prehospital phase (i.e. in the ambulance) in order to directly allocate them to such a specialized CSC will save vital time (time=brain!). Several LAVO-prediction scales for clinical triage have been developed but most were tested in- hospital by experienced neurologists. Consequently, there is a great need for validation of these scales in the prehospital setting by Emergency Medical Services "EMS" personnel. Objective: to recalibrate, validate performance and assess feasibility of several existing LAVO-prediction scales in the prehospital phase (i.e. assessment by EMS personnel). Study design: multiregional, multicenter observational cohort study to investigate performance and feasibility of LAVO-prediction scales a. Study population: all patients potentially eligible for IVTIAT according to the protocol used by EMS personnel except for when younger than 18 years.
Carotid diaphragms are a non-atheromatous arterial cause of cerebral infarction, especially in young people (≤65 years old). This anomaly is more common in the African or African-American population, although it is more and more often discovered in young Caucasians. This cause of cerebrovascular accident (CVA), known until the 1970s, was later forgotten until a recent revival of interest, probably in connection with the improvement of imagery but also by the discovery that these lesions have a high rate of recurrence in the absence of interventional care. In a Brazilian study, the carotid diaphragm was reported in 10% of patients under the age of 60. The carotid diaphragm is a non-atheromatous overgrowth of the intima of the arterial wall. It appears in imagery in the form of an endoluminal web wider than it is tall. Its preferred seat is the carotid bulb. It is a source, by an embologenic mechanism, of cerebral infarction starting from local thrombus developed within large cerebral arteries. In histology, the lesions are different from atherosclerosis and characterized by a thickening of the intima with proliferation of loose and strewed spindle cells mainly involving the intima. An atheromatous plaque or dissection with detachment of the intima are the two main differential diagnoses of the carotid web. However, the appearance of a diaphragm implanted on a regular wall and the absence of any other localization of atheroma distinguish the lesion of the carotid web from that of a focal atheromatous plate. In addition, the very proximal localization of the carotid web, from the emergence of the internal carotid artery, does not suggest a dissection, the localization of which is usually downstream of the bulb. The baseline exam to detect a carotid diaphragm is a carotid angiography scan, but the abnormalities are often inconspicuous, making diagnosis difficult. We can be led in case of doubt to perform a conventional arteriography, which remains the "gold standard". The latter, dynamic examination compared to the CT scan, shows above all a stasis of blood flow in the recess created by the diaphragm, stasis at the origin of the formation of thrombi. It has been suspected that the maximum risk of infarction is upon waking, at the time of verticalization, with mobilization of the thrombus. Therapeutically, the discovery of a symptomatic carotid diaphragm (ischemic swallowing accident) justifies radical treatment. The risk of recurrence of a patient on antithrombotic (antiplatelet or anticoagulant) being too high, it is proposed either surgery, or carotid angioplasty with stent placement. No comparative study of the 2 techniques has been carried out. Besides radiological examinations, ultrasound is another technique for studying the cervical arteries. It is reputed to be of little contribution in the search for a carotid diaphragm, but few publications exist to date even though the cervical Doppler is often the first arterial examination carried out after an ischemic stroke. Two series reported Doppler ultrasound data in the carotid diaphragm. A recent retrospective study evaluated, in multimodal imaging [Doppler, CT scan of the Supra-Aortic Trunks (ASD) and conventional arteriography], 30 patients (60 carotids) with diaphragm or atherosclerosis. The correlation between conventional arteriography and CT angiography was perfect, but the correlation between Doppler and CT angiography for diaphragm diagnosis was moderate. In another series studying 15 diaphragms diagnosed by CT angiography, the retrospective analysis of doppler reports revealed that 40% were considered normal and 60% mentioned nonspecific hyperechoic lesions, but this work remained in the form of a presentation. at a congress. With the improvement of the technique and the resolution of the Doppler ultrasound as well as the knowledge of the particular ultrasound characteristics, it seems to us that this examination could regain a place in the diagnosis of the pathology. The carotid diaphragm is also largely unknown to vascular doctors practicing cervical Doppler ultrasound. This descriptive study of the diagnostic contribution of the echo-doppler for a carotid diaphragm has for perspective the establishment of a prospective study of the contribution of a combined expertise angiologist-neurologist in the echo-Doppler for patients <60 years hospitalized for an ischemic stroke.
This study aims to investigate the immediate, accumulated, and maintainable effects of treadmill with biofeedback on gait symmetry in individuals with chronic stroke.
Music that is familiar and preferred by patients has been shown to heighten neuroplasticity and can mitigate these disabilities. Therefore, this study seeks to explore the effect of providing patient preferred music to patients in the very early post stroke period (within 24 hours of a left cerebral artery stroke [LMCA]event) as a complementary modality to usual stroke care.
The purpose of this randomized controlled trial was designed to study the efficacy of dynamic hand splinting on spastic hemiparetic patients due to stroke or traumatic brain injury.
The specific study aims will be: 1. To develop the novel, digital, and interactive MSR system of arm and hand with integrated digital action observation therapy (AOT) and mirror therapy (MT). 2. To pilot usability testing for examining the feasibility of this new MSR system from the users' experiences and feedback. 3. To examine the treatment effects of digital AOT, digital MT and a control intervention in patients with stroke by conducting a randomized controlled trial. 4. To identify who will be the possible good responders to digital AOT and MT based on their baseline motor function and mental imagery abilities.
Compared to conventional rehabilitation therapy, the full-immersive commercial game (CG) system, in the form of available video game, could safely provide more positive effect on health-related quality of life (HRQOL) and motor function in post-stroke patients. The study aims to perform the research from 2019/7/1 to 2021/6/30 and enrolls a total of 80 participants. Stroke participants are recruited from the rehabilitation ward of CGMH hospital. The inclusion criteria are (a) first-time unilateral cerebral stroke, (b) stroke onset less or equal to 1 year, (c) admission to the rehabilitation ward, (d) ages 20-80 years, (e) spasticity of paretic arm ≤ grade 2 in the Modified Ashworth Scale, and (f) no active medical problems such as fever, pneumonia, or scabies. The exclusion criteria are (a) brainstem or cerebellar stroke, (b) epilepsy history, including photosensitive epilepsy, (c) previous or active heart diseases, such as myocardial infarction or angina, (d) visuospatial problems related to stroke, such as hemianopia or hemineglect, (e) paretic upper limb reaches Brunnstrom recovery stage VI, (f) severe aphasia, (g) severe cognitive impairment, and (h) poor cooperation with assessments. All participants are randomly allocated to study group and control group. Participants in the control group receive conventional rehabilitation therapy over 50 minutes on weekdays. Participants in the study group receive conventional rehabilitation therapy over 50 minutes on weekdays and 7 sessions (flexible schedule in different day) of PlayStation®VR of 20 minutes each in the main 16-day study period. Pre-intervention, post-intervention, and 3-month follow-up HRQOL will be assessed by the Stroke Impact Scale 3.0. Motricity Index and Fugl-Meyer Assessment, Functional Independence Measure, and arm movement ratio will also be checked before intervention, after intervention, and at 3-month follow-up. The safety outcome, intervention-related adverse events or any serious adverse events, during study period will be recorded.
Additional trunk therapy is proven to be effective for improving trunk function and sitting balance. However, conventional trunk therapy is limited by the needed supervision of a therapist and when using unstable surfaces, only a small patient group can profit from this training. Rehabilitation technologies are considered an effective add-on to conventional therapy in order to improve semi-independent training at a high-intensity for a broad type of patients. For the trunk, only few devices exist, mainly used for research purposes and not adapted to clinical needs. Therefore, a prototype to train the trunk of the patient was developed (T-Chair), in order to train trunk control and sitting balance. After the first usability study with the first T-Chair prototype, it was found that the device was usable and safe but it needed further improvements. Over the past year these improvements have been made. Therefore the goal of this feasibility study is to investigate the usability of the new T-Chair 2.0 prototype, as well as the possible effect the device could have on trunk control and lower extremity function. To do this, 30 persons in the subacute phase post stroke will be included in the study and randomly assigned to the experimental or control group. Participants in the experimental group will perform in addition to their normal general rehabilitation programme, additional therapy with the T-Chair 2.0, three times per week for four weeks. Participants in the control group will perform their normal general rehabilitation programme. Before training at T0, trunk function, trunk muscle strength, lower extremity function, lower extremity muscle strength, sitting balance, general mobility, cognition and level of neglect will be evaluated. Directly after each therapy session feasibility in terms of demand, safety, handling, acceptance, comfort, exertion of exercises and general feedback will be evaluated. After four weeks at T1, all measurements will be repeated.
