Filter by:BACKGROUND: In 30-40% the cause of ischemic stroke remains undetermined. Most likely, this category hides an additional number of strokes caused by artery-to-artery embolisms due to unidentified atherosclerotic disease, or caused by cardioembolism. Both types are associated with a high risk of recurrent ischemic events and multiple cerebral infarctions. Large-artery atherosclerosis of the brain-supplying arteries is the assumed underlying cause in 10 to 15% of ischemic stroke, mostly deriving from the extracranial carotid artery. Carotid intima-media thickness (cIMT) measured by 2-dimensional (2D) B-mode ultrasonography and estimation of the overall atherosclerotic plaque burden aids future risk prediction. Arterial wall changes, artery caliber variations, degree of stenosis, local hemodynamic alterations and certain plaque characteristics are important for the evaluation of plaque vulnerability and vascular risk stratification. Transcranial Doppler monitoring (TCDM) is a non-invasive bedside examination eligible for detection of microemboli in the human cerebral circulation. HYPOTHESIS: Atherosclerotic stenosis and plaque characteristics can be more accurately assessed by the combination of routine 2D ultrasound, contrast enhanced ultrasound (CEUS), and 3-dimensional (3D) ultrasound. TCDM, CEUS and 3D visualization of the carotid plaque improve the differentiation of stroke etiology and quantification of plaque vulnerability, and aid the prediction of future risk for cerebrovascular events in the individual patient. AIMS: Assessment of prevalence and frequency of Microemboli signals (MES) in unselected patients with cerebral ischemia, the influence of antithrombotic drugs on MES, and the relationship between MES and recurrent stroke or Transient ischemic attack (TIA). Categorization of atherosclerotic carotid artery disease by use of routine and advanced neurosonographic techniques combined with anamnestic and clinical data. Development of a visualization solution tailored for 3D visualization of carotid arteries and semi-automatic plaque segmentation.
Stroke is one of the major cause of morbidity and mortality and the leading cause of disability in adults all around the world. Stroke survivors can suffer several neurological impairments and deficits which have an important impact on patient's quality of life and which increase the costs for health and social services. After stroke, impairments in ADLs and functional status, deterioration in health related quality of life can be seen. Although most of the stroke survivors experience some level of neurological recovery, nearly 50%-60% of stroke patients still experience some degree of motor impairment, and approximately 50% are at least partly dependent in activities-of-daily-living (ADL). Gait recovery, performing activities of daily living and regaining independence in ADLs are the main focus of stroke rehabilitation programs. Robotic technologies are becoming more promising techniques for the locomotor training in stroke patients. Achieving a functional walking level is one of the target of robotic gait training and it has been shown that Robotic-Assisted Gait Training (RAGT) improves walking function in stroke patients. Having a functional gait level may help the stroke patients to regain independence in ADLs and improve quality of life. The purpose of the present study was to investigate the effects of RAGT on functional status, ADLs and health related quality of life.
Commercial interactive game consoles including the Nintendo Wii™ and the Sony Playstation Eyetoy™ have been used in stroke rehabilitation with variable success and seemed to be safe, feasible and effective treatment options. The more recently released Xbox Kinect™ game console has superiorities to the others such as not requiring any special controller and having a more sensitive sensor which provides more accurate motion-capturing. However, there is limited evidence on clinical utility of the Xbox Kinect™ in stroke rehabilitation. Currently it has been designed for physically and mentally healthy people just like previous consoles. Therefore, the safety and feasibility of the system should be evaluated in first place before using it as an alternative or adjunctive training method in stroke patients. To the best of our knowledge, no studies have evaluated the clinical feasibility of the Xbox Kinect™ in stroke rehabilitation. The aim of this pilot study was to evaluate the feasibility and safety of the Xbox Kinect™ training of upper extremity in subacute stroke rehabilitation. The secondary aim was to evaluate its efficacy on upper extremity motor and functional recovery.

Stroke is the fifth leading cause of death in the United States and the leading cause of disability. However, in China, stroke is one of the most frequent causes of death and chronic disability. Ischemic strokes in adults younger than 45 years of age were regarded as a relatively uncommon event in the proportion of <5% of all ischemic strokes.
Cervicocerebral artery dissection is a major cause for stroke in young adults. While knowledge of cervical artery dissection (CeAD) has increased thanks to a number of high quality studies, knowledge on intracranial artery dissection (IAD) is limited. Due to treatment and publication bias little is known about the natural history of IAD. Overall, IAD is assumed to have a more severe course than CeAD, with a more ominous outcome in patients with subarachnoid hemorrhage (SAH). Furthermore, little information is available on the risk of recurrent IAD as well as on the risk of recurrent ischemic and haemorrhagic events in non-Asian patients. Radiological diagnosis of IAD can be challenging given the small size of intracranial arteries, and the subtle and non-specific radiological signs which tend to evolve over time. The optimal treatment of IAD is unknown. There are no randomised trials and only observational studies with relatively small sample sizes are available, thus providing a very low level of evidence. Finding the factors that are decisive for outcome and recurrence after intracranial artery dissection is key to an improved management of this potentially severe disease predominantly affecting young patients. By using standardised protocols for diagnosis, imaging and follow-up, the investigators intend to obtain large representative patient samples in order to fill the gap of evidence.
Investigation of the clinical feasibility and efficacy of a newly developed robot-assisted gait training system for acute stroke survivors. It is anticipated that robot-assisted gait rehabilitation will achieve significantly better gait and quality of life outcomes than the standing table rehabilitation.
Stroke is one of the most common chronic disabling conditions in Hong Kong. People after stroke may suffer from certain degree of physical impairment and disability. Resuming safe ambulation in the community appears to be a big challenge to them as it always involves the simultaneous performance of two or more tasks (dual task) such as walking and talking with someone, walking and recalling the shopping list etc. Numerous studies has demonstrated that the interference from dual tasks (dual task interference) may significantly impact the recovery of the functional walking. To date, the relevance of dual task walking to daily community is widely documented and the ability of managing dual task is therefore particularly important. Evidences supported that dual task training showed its promising effect on the balance and walking performance amongst people with neurological disorders, such as chronic stroke. In light of this, the introduction of dual task based balance and walking training into physiotherapy program for stroke patient may enhance the balance and walking performance and hence promote successful community ambulation. Yet, there is limited evidence on its effect in sub-acute stroke. Objective: To examine the effectiveness of a dual-task based balance and walking training program on performance and dual task interference in balance and walking ability, balance self-efficacy and incidence of falls in people with sub-acute stroke
