Active clinical trials for "Stroke"

This prospective observational study will be assessing whether it is practical and feasible to use a stroke screening tool (the modified NHISS, mNIHSS) in an adult surgical population. Perioperative stroke is an uncommon but devastating complication of surgery and previous research suggests that stroke symptoms may be missed in this population. This stroke screening tool has been used extensively in non-surgical patients but has not be used in non-cardiac surgical patients. Surgical patients have additional factors that may affect their ability to complete this assessment such as pain medications and sedatives, pain, and use of epidurals and nerve blocks. This study will involve a total of five testing sessions. The first will occur at the time of consent to screen for cognitive impairment via the Montreal Cognitive Assessment (MoCA), as part of our exclusion criteria. Then over the course of four subsequent visits, participants will be assessed on the mNIHSS to track for any changes before and after their procedure, as well as evaluate the real-life usability of the mNIHSS as a potential tool to screen for stroke in the surgical population.

For a long time, delirium was considered a merely temporary dysfunction of the brain. Today, it is established that it is a brain disease associated with network dysfunction, neuroinflammation and impaired transmitter homeostasis in a multicausal model. Following an episode of delirium, many patients do not return to their prior level of cognitive and functional performance. In particular, failed or delayed diagnosis with consecutive inadequate therapy contribute to the development of long-term cognitive decline that may ultimately lead to long-term care. Stroke patients are a particularly common delirium-affected population (10-46% depending on severity). Despite the frequency and clinical relevance of delirium in stroke patients, diagnostic characteristics of common screening methods are unknown. Similarly, the clinical phenotype and risk factors of patients who develop delirium have not been adequately described. This study primarily aims to evaluate the diagnostic properties of established screening tools for delirium in a prospective cohort of well-characterised patients following ischemic cerebral events (either transient or manifest stroke). Secondary outcome criteria include predictors of post-stroke delirium (PSD) such as stroke location and size, pre-stroke cognitive functioning, ability to participate in daily routine activities and medical conditions.

Elevated level of serum troponin (T-I) has been regarded as a prognostic biomarker of poor outcome in acute ischemic stroke. However, its role in outcome in thrombolysed ischemic stroke patients remains uncertain. The aim of this study was to evaluate the role of T-I as a predictive biomarker of short-term outcome in thrombolysed ischemic stroke participants.

Gait analysis is commonly performed in clinical practice. However, it is complex and requires an understanding of the activation of muscles in lower limbs, trunk, and upper limbs in a specific spatiotemporal pattern and the appropriate joint positions which support and advance the body weight in different phases of gait cycles. In study, we plan to pilot the application of 3D gait analysis with statistical modelling in 2 common causes of gait deviation: unilateral hemiplegic stroke and unilateral lower limb amputation.

The aim of this study is to examine the functional recovery results of the Bobath (NDT) approach in patients with primary brain tumors and compare the results with those of stroke patients.

This cohort study will evaluate the relatiobship of stroke recurrence and anti-platelet resistance in ischemic stroke patients

The aim of this study is to investigate the prevalence of sarcopenia in stroke patients; to determine the relationship between sarcopenia and duration of stroke, age, gender, etiology of stroke, ambulation status, spasticity, nutrition and malnutrition

Caregiver's burden in rehabilitation is important for both patients physical and mental health. Therefore researching caregivers burden and treatment of any depression or associated any psychological disorders of caregiver is crucial.

In subacute stroke patients, dynamic time series data of brain imaging and motor function measurement were obtained from 7 days to 6 months (total 9 times) after stroke onset

After a stroke, more than two out of three patients experience problems with upper limb movement and sensation. During the past decade, robotic technology has been increasingly used to asses these problems in a detailed and accurate manner. However, sensory processing, one of the most important sensory functions, has not been assessed using robotic technology yet. Therefore, the investigators have developed a robotic assessment of sensory processing. During this study, the investigators aim to initially validate this novel assessment. The investigators aim to examine 20 chronic stroke patients and 20 age-matched healthy controls using the robotic assessment on one hand, and a set of existing clinical assessments on the other hand. The investigators hypothesize that stroke patients will have a poorer performance on this novel robotic assessment compared to age-matched healthy controls, and that these findings are similar to what is found with existing clinical assessments.
