Filter by:Subjects will receive 30 treatments with AMES, to the proximal arm which has been affected by a chronic stroke.
Objective: The study aim to establish high risk admission model and readmission model for elderly in Taiwan. Method: Investigators compare the clinical, epidemiological, and socioeconomic characteristics of admitted patients during 1 August,2011 to 31 July,2012. All patients will follow up to end of study to identify 14 days readmission and 30 days readmission to geriatic ward. Expected Outcomes: (1) To compare the prediction value of derivation cohort and validation cohort. (2) To identify high risk indicators of admission and readmission for elderly. (3) To determine the risk factors in admission elderly association with quality indicators.
Task-oriented exercises combined with strengthening have been shown effective in improving walking functions in patients with chronic stroke. However, similar approaches of therapeutic exercises have not been applied to subacute stroke with long-term follow-up, using outcome measures across the three levels of functioning (body functions/structure, activities, and participation) of the International Classification of Functioning, Disability, and Health (ICF) model. Therefore, this study will be conducted to fulfill three purposes: 1. To investigate the long-term effects of a four-week task-oriented lower extremity strengthening training (TOLEST) program in patients with subacute stroke; 2. To investigate the interrelationships among functional connectivity of the brain, lower extremity motor functions, physical activity level, and quality of life in patients with stroke who have received this four-week TOLEST program in the subacute phase of stroke; and 3. To identify prognostic factors for recovery in functional connectivity of the brain, lower extremity motor functions, physical activity level, and quality of life in patients with stroke who have received this four-week TOLEST program in the subacute phase of stroke.
After having had a first cardiovascular event, there is a considerable risk of developing a subsequent event. Only recently, a risk prediction model was developed for this group of patients. Imaging techniques such as the coronary artery calcium score and contrast-enhanced computed tomography (CT) of the coronary and carotid arteries could be able to add improve this model. Imaging may further improve the prediction of future manifestations of arterial disease and personalize disease monitoring and treatment.
1. To investigate the efficacy and safety of multi-doses Compound Edaravone Injection versus Edaravone Injection for acute ischemic stroke patients; 2. To provide evidence for the design of Compound Edaravone Injection Phase III trial.
Intravenous tissue plasminogen activator (IV t-PA) is the only proven treatment of hyperacute cerebral infarction. The outcome of this treatment highly depends on the time from symptom onset to the administration of thrombolytic agent. Last known normal time is widely used as the standard to determine the symptom onset. These stroke symptoms are usually caused by a sudden decrease in cerebral blood flow related with an embolic or thrombotic event. However, in some cases various symptoms may occur one after another. Myocardial infarction is also caused by a sudden caseation of blood flow. The symptom of myocardial infarction usually contains chest pain, and it is easy to identify the exact time of onset. In contrast, cerebral infarction may cause various symptoms according to the infarcted area of the brain, and sometimes multiple symptoms are presented in rapid succession. Therefore, it may be much unclear and uncertain to determine the onset time of cerebral infarction. Despite the importance of onset time in therapeutic decision making, there was no study focusing on the certainty of onset time in cerebral infarction patients. In this study, we will investigate the subjective certainty of patient about the onset time in clear-onset cerebral ischemia. The discrepancy in diagnosing the onset time will be analyzed among the clinicians involved in the practice. Then, the factors associated with this uncertainty will be verified.
The few studies looking systematically into the neurophysiological and neuropsychological components of available therapies for chronic aphasia are highly heterogeneous in nature. Results from these studies have, unsurprisingly, indicated heterogeneous results, such as dissimilar neural outcomes associated with neuropsychological gains. There is, therefore, no consensus of how a successful therapy— that is, one that produces a measurable language gain in either production or comprehension —impacts the functional language networks of the brain in a specific type of aphasia population. A recent study has shown that inner speech (the imagination of speech) involves networks and areas dissociable from those implicated in speech production. Further, behavioural analysis has shown an interesting discrepancy between inner speech and overt speech (also called speech production) in a small chronic aphasia population: some participants elicited poor inner speech coupled with relatively intact overt speech, while others elicited relatively intact inner speech coupled with poor overt speech. This unexplored discrepancy implies that inner speech and speech production are dissociable, though share similar networks. This discrepancy, and the notion that these speech components share a similar network, drives this study's hypothesis that improvement in speech production after rehabilitation might be facilitated by an intact inner speech network. Much as good athletes visualise their performance before the actual event in order to increase their chances of success, so too might intact inner speech facilitate speech production, helping to visualise the word in order to increase the success of produced speech. By studying a specific component of speech—inner speech—in a relatively homogeneous population of chronic expressive aphasics, the present study provides an explicit, critical means of understanding neurophysiological (as assessed by functional magnetic resonance imaging) and neuropsychological (as assessed by language batteries and personal questionnaires/interviews) changes occurring during speech therapy. As a secondary objective, this study will explore the effectiveness, feasibility and adherence to an at-home computerised aphasia software delivered via a portable tablet.
The purpose of this study is to determine if transcranial direct current stimulation (tDCS)applied over the lower extremity motor cortex in conjunction with treadmill training is effective for improving gait in patients with subacute stroke and to evaluate the effect and predictive value of a single session of anodal tDCS.
The purpose of this study is to investigate the effects of treatment for specific language deficits in people with aphasia. In addition to language and cognitive measures, changes in brain function will also be gathered before and after the treatment is administered in order to track any changes resulting from receiving treatment.
Background: Recent studies have demonstrated that even mild stroke survivors experience residual damage, which persists and in fact increases in subsequent years. About 45% of stroke victims remain with different levels of disability. While studies on cognitive impairment and dementia after stroke are receiving increasing clinical attention, the underlying pathophysiology is poorly understood. Identifying the mechanisms involved and recognizing early biomarkers for individual vulnerability, require a multi-modal approach, as the mechanisms involved in cerebrovascular disease and individual trajectories of post-stroke recovery may impact upon each other on various levels. Aims and Hypothesis: To date there is no single measure that can be used to identify patients who are prone to develop cognitive impairment and other disabilities from those with better recovery prospects. We hypothesize that data based on biochemical, neuroimaging, genetic and psychological measures can, in aggregate, serve as better predictors for subsequent disability, cognitive and neurological deterioration, and suggest possible interventions. Design: The TABASCO (Tel-Aviv Brain Acute Stroke Cohort) study, a prospective cohort study aim to recruit about approximately 1125 consecutive first-ever mild-moderate stroke patients. It is designed to evaluate the association between predefined demographic, psychological, inflammatory, biochemical, neuro-imaging and genetic markers, measured during the acute phase, and long-term outcome: subsequent cognitive deterioration, vascular events (including recurrent strokes), falls, affective changes, functional everyday difficulties and mortality. Discussion: This study is an attempt to comprehensively investigate the long term outcome of mild-moderate strokes. Its prospective design will provide quantitative data on stroke recurrence, the incidence of other vascular events and the evaluation of cognitive, affective and functional decline. Identifying the factors associated with post stroke cognitive and functional decline could potentially yield more effective therapeutic approaches. The investigators believe that an extensive approach of analyzing the interaction between different risk factors would more accurately predict neurological and cognitive deterioration.
