Active clinical trials for "Stroke"

Prehospital stroke care in specialized ambulances increases thrombolysis rates, reduces alarm-to-treatment times, and improves prehospital triage. Preliminary analyses suggest cost-effectiveness. However, scientific proof of improved functional outcome compared to usual care is still lacking. The objective of this trial is to show improved functional outcomes after deployment of a Stroke Emergency Mobile (STEMO) compared to regular care.

This is an online study that involves assessment and training of arm function at home. Stroke is the leading cause of disability worldwide. Of the annual incidence of stroke (~750,000) in the USA about 60% fail to recover arm and hand use contributing to reduced quality of life for survivors and caregivers. How can therapists facilitate the rehabilitation of individuals with arm movement deficits and increase their quality of life over a long time period? It is known that principles of treatment including repetition, feedback, challenge and progression are important for producing recovery. The ability for patients to train at home and manage their own rehabilitation duration, intensity and progression, via effective self-management strategies, is vital. What is needed is an effective, easy to use, low cost system that self-motivates patients to intensively practice their therapy exercises at home while maintaining elements of repetition, feedback, challenge and progression. In this proposal the investigators intend to adapt just such a "web-based system" originally designed in the UK. The first version of the system has shown preliminary efficacy and feasibility in a small pilot study in UK. The investigators will adapt the system for use in the USA, with the assistance of consultants from the UK. The purpose of this study is to investigate the efficacy and feasibility of using a free, easy to use, interactive web-based upper extremity stroke rehab program on individuals with stroke who have been discharged from outpatient rehabilitation. The goal is to compare the home use of the web-based stroke rehab program with that of written exercises in a randomized controlled trial. The aims/objectives are to (1) adapt the existing system for use in America including adding bilateral activities and then to assess (2) motor function immediately before and after six weeks intervention and after 12 weeks follow up in order to support the efficacy of using this web-based intervention; (3) behavioral changes in motivation and self-efficacy at the same time points to understand the relationship between behavioral and motor function changes; (4) perceptions of patients and caregivers of the web-based program to understand feasibility and barriers to home use; and (5) perceptions of therapists to understand feasibility and barriers to clinic use.

The proposed study is a Stage I successive cohort trial intended to adapt Acceptance and Commitment Therapy (ACT) to meet the specific needs of stroke survivors with aphasia ("ACT for Aphasia"). It will do so by incorporating communication supports and compensatory speech-language treatment. The goal of developing this integrated treatment is to improve successful communication participation, psychosocial adjustment, and quality of life for stroke survivors with aphasia. In the first phase of the project, the investigators will create a treatment manual with input from a stakeholder advisory board consisting of caregivers and stroke survivors with aphasia. The investigators will then recruit an initial cohort of five stroke survivors with aphasia to undergo the initial version of the treatment based and provide feedback. This will aid revision of the manual, which the investigators will then evaluate using a second cohort of 16 stroke survivors with aphasia. The investigators predict that ACT for Aphasia will be acceptable and feasible based on measures of participant satisfaction and treatment adherence. The investigators will also measure pre- to post-treatment changes in psychological distress, functional disability, quality of life, and communication participation and functioning to establish preliminary effect size estimates for this intervention, in preparation for a subsequent Stage II efficacy trial.

To explore the safety and feasibility of intra-arterial neuroprotective strategy in acute ischemic stroke patients who missed recanalization operation.

The aim of this study is to examine the effect of an additional VR training program on unilateral spatial neglect (USN) after stroke. Principally, clinical assessment of the presence of unilateral spatial neglect and additionally the severity of USN will be measured using the Behavioral Inattention test (BIT), using only the BIT Conventional subtest (BITC). Secondarily, the VR outcomes will be included as well. Finally, we want to determine if the effects last over a short period of time. It is important to know whether the potential effects of the VR-training remain without continuing the intervention. Therefore, we will perform a follow-up assessment after 1 week.

Of the 795,000 people who experience a stroke every year in the US, only a small percentage will achieve full recovery. While current therapies promote strength and endurance, none directly address the unique potential of the brain to reorganize following injury. The goal of this project is to explore the effects of a novel therapy, acute intermittent hypoxia (AIH). During this therapy, individuals receive brief bouts of reduced oxygen levels by inhalation through a face mask. (This is akin to being on top of a tall mountain). In brief exposures, AIH is known to trigger the release of specific proteins that help the brain adapt to oxygen reductions. Published results in people with incomplete spinal cord injury have shown that AIH enhances muscle strength and coordination rather quickly. The research team aims to study the effects of AIH in stroke survivors.

Investigation on changes in the neurochemical stress parameters in acute stroke. 30 patients are recruited in the stroke unit, blood samples are collected at fixed intervals during the first two days. Patients are randomized to music listening and control.Neuropsychological testing is performed in the acute phase and 6 months post-stroke.

Stroke is a syndrome of acute, focal neurological deficit attributed to vascular injury of the central nervous system. It was the 2nd leading cause of death worldwide and accompanied by high disability rate also increases the social burden.Our research is to investigate the effects of intervention with Bifidobacterium longum OLP-01 on cognitive function, exercise performance, nutritional status and gut microbiota in stroke patients. Study population: We will recruit 120 stroke patients and the inclusion criteria are: (1) Aged 20-75 years old, (2) Diagnosed with stroke more than 3 months, (3) Undergoing outpatient rehabilitation and the condition is stable. The exclusion criteria are: (1) Aphasia, dementia or depression, (2) BMI ≥ 35 kg/m2, (3) Cancer treatment in 3 months, (4) Some severe disease may interfere patients to join the study, (5) Failed to cooperate the examination and treatment because of emotion or mental condition. Study design: A two-arm single-blind randomized controlled clinical trial will be performed for 12 weeks and the subjects will be divided in to 2 groups: (1) placebo group, (2) supplement group. Subjects were asked to supplement with either 2 × 1010 colony-forming unit (CFU) of Bifidobacterium longum OLP-01 powder per day or placebo for 12 weeks. Medical history, drug use and life style questionnaires were giving before intervention. Outcomes will be assess in week 0 and week 12 during intervention. 3.
