Active clinical trials for "Stroke"

This is a randomized, triple-blind, placebo-controlled, multicenter clinical trial. Eligible patients will be randomized into either the butylphthalide (NBP) or placebo group in a 2:1 ratio.The main purpose of this study is to determine whether butylphthalide can improve dynamic Cerebral Autoregulation (dCA) in large-artery atherosclerosis acute ischemic stroke.

Stroke is the leading cause of adult disability in the United States, and aphasia is common following a stroke to the left hemisphere of the brain. Aphasia therapy can improve aphasia recover; however, very little is known about how different patients respond to different types of treatments. The purpose of this study is to understand how the following factors influence an individual's response to aphasia treatment: 1) biographical factors (e.g., age, education, gender), 2) post-stroke cognitive/linguistic abilities and learning potential, and 3) the location and extent of post-stroke brain damage. We are also interested in understanding the kinds of treatment materials that should be emphasized in speech/language treatment. Overall, the goal of the current research is to inform the clinical management of post-stroke aphasia by identifying factors that can predict how an individual will respond to different treatment methods.

The purpose of the project is to investigate specific markers in blood samples from patients with stroke (ischemic or hemorrhagic). This could hopefully help in the early diagnostic to separate patients with ischemic stroke from those with hemorrhagic stroke as treatment are different and patients need to come quickly to the correct treatment site.

The goal of this study is to learn more about the connections between the brain, spinal cord, and muscles and how these connections can be strengthened after neurological injury.

This research will present the biomechanical assessment of a robotic device for ankle assistance during gait on stroke's survivors with hemiparesis. Gait pattern through an optoelectronic motion capture system will be analyzed. Additionally, ergonomic and comfort aspects will be measured by an adapted spanish version of Quebec User Evaluation of Satisfaction with assistive Technology (QUEST)

Stroke is the leading cause of disability and diminished quality of living that frequently includes impairments of postural control and upper extremity (UE) function. The interaction of posture and UE coupling in terms of movement planning, initiation, and execution is not well understood. StartReact responses triggered by a loud acoustic stimulus (LAS) during the planning and preparation of goal intended actions has been used to probe the state of brainstem neuronal excitability related to posture and movement sequencing. The purpose of this study is to examine posture and goal-directed movement planning and execution using startReact responses and to evaluate posture and UE movement sequence during reaching while standing in individuals with chronic hemiparesis and healthy controls. Secondly, the investigators will determine the modulatory role of the cortical premotor areas (PMAs) in startReact responses in healthy controls and in persons with stroke by using transcranial direct current stimulation (tDCS) to up- or down-regulate PMAs excitability.

In the present study, the RMTC finger-hand robot and combined with the mechanism of neuroplasticity will be used on the upper-limb rehabilitation of stroke patients. The participants will be randomized assigned to treatment group (TG, robot assisted treatment) and control group (CG, conventional treatment). In the experimental group, task oriented bi-manual training will be applied using the unaffected hand to guide the affected hand by RMTC robot system. The investigators will estimate the motor function of distal part of upper-limb before and after treatments. The results will be compared with the convention rehabilitation treatment. The primary outcomes are Fugl-Meyer assessment (FMA); and the secondary outcome measurements are modified Ashworth scale (MAS),Action Reach Arm Test (ARAT), Box & block test、Brunnstrom recovery Stage, and motor activity log (MAL).

The long-term goal of this project is to develop upper limb rehabilitation interventions that can be utilized for stroke survivors, specifically survivors with more severe limitations in use of their affected upper limb. This study will utilize a novel method of non-invasive brain stimulation in conjunction with upper limb training given for 12 visits over a period of 6 weeks. The study will include the following site visits: Eligibility Screening and Informed Consent Visit An MRI visit Two testing visits in which motor function of the upper limb and neurophysiology will be measured 12 intervention visits during which patients will receive upper limb training in conjunction with non-invasive brain stimulation Repeat testing of motor function of the upper limb and neurophysiology Repeat MRI testing A follow-up visit completed 3 months after the completion of interventions

Multicenter, randomized, placebo-controlled, double blind, phase 2b trial of acute stroke patients treated with mechanical thrombectomy (MT), in which two therapies are compared: rt-PA or placebo. Allocation at each center will account for 1 stratum: use of alteplase (yes vs. no) before MT. Subjects will be followed up to 90 days post-randomization.

This is a pilot randomised controlled trial investigating a combination of unilateral strength training (cross-education) and mirror therapy for the rehabilitation of upper limb impairment following a stroke. This study has been conducted as part of a PhD qualification at the Institute of Technology Sligo in Ireland with all assessments being conducted at the institute and all therapy sessions taking place at the participant's home. The study was conducted in conjunction with Sligo University Hospital and it attained ethical approval through the relevant University Hospital Ethics Committee.
