Active clinical trials for "Stroke"

This study is aimed to determine the effects of an accompanying structured cardiopulmonary rehabilitation program along with a neurorehabilitation program on the quality of life, care-giver burden and overall well-being of the patients.

About 150,000 people in the UK suffer a stroke each year and ~60% with moderate to severe stroke fail to recover arm or hand use. Stroke rehabilitation is increasingly home-based following early supported discharge (ESD) from hospital to facilitate self-management and avoid problems associated with prolonged hospital stays. There is strong evidence that intensive practice and re-education of normal movement is essential for functional motor recovery, hence the NHS guideline of 45 minutes therapy 5 days per week, but NHS Trusts have difficulty meeting this target due to cost and access to specialist therapists. An M-MARK Mk1 device that combines an Inertial Measurement Unit (IMU) with an Mechanomyography (MMG) sensor has been designed and laboratory tested. Novel signal processing techniques have been demonstrated that reduce problems of vibration artifacts and generate information on mechanical muscle activity and movement. The aim of the overall M-MARK project is to develop a low-cost wearable wireless device (Mk2) that patients can use independently at home while practicing standardised everyday activities to regain upper limb function. Mk2 M-MARK has now been developed in collaboration with therapists, patients and their carers. The system incorporates feedback, presented on a computer/tablet, as motivating visualisations of movement showing them if they have moved in the correct way. A separate interface has been developed for therapists, which offers a simple system to diagnose specific movement problems to inform clinical decision-making, monitor progress and thus increase efficiency of therapy. In phase 1 of this study, user requirements were assessed to inform the development of the Mk2 M-MARK for clinical use. Ten patients and carers were interviewed and 20 health professionals took part in two focus groups, from Portsmouth Hospitals NHS trust and North Bristol NHS Trust. The Mk2 system has now been developed, reliability demonstrated and iterative testing with stroke patients has ensured usability of the system. This phase of research will examine the clinical feasibility of using Mk2 M-MARK with stroke patients who are undergoing early supported discharge. All feasibility aspects of the wearable system will be assessed including usability and safety. Preliminary data on efficacy will be collected and a health economics analysis will be undertaken.

In this study the investigators want to test the hypotheses that, serotonergic neuromodulation increases perilesional neuroplasticity, leading to improved behavioural outcomes through a more efficient allocation of functional resources, greater structural reorganization and less remapping via alternative circuits.

Associated with the worsening of functional capacity of older adult and the lack of guidance on how to care of them after stroke, the family caregiver starts to fell burden related to the care, and the quality of life was affected by that burden. Besides that, the older adult began to use more frequently health services and had more hospitalizations by preventable conditionals with adequate care. The aim of this study is to evaluate the effectiveness of educational interventions of care at home provide by nurses to family caregivers of older adult with stroke after hospital discharge, compared with usual care guidelines or no guidance, in one month follow up. The family caregivers of older adults post stroke with the first functional sequel from the Clinical Hospital of Porto Alegre (HCPA) will participate in the study. The intervention will involve the systematic monitoring of nurses through home visits (HVs) during one month. Thus, will instrumentalize the family caregiver to care of older adult with stoke according the protocol developed in a research group and the needs of care of them. The control group won't receive the home visits and could have or not the usual care guidelines provide by health services that have access.

The purpose of this pilot study is to investigate the clinical effects of a new upper limb robot assisted therapy device that is linked to a virtual therapy environment in patients with stroke.

It has been found that arm and leg cycling is similar to walking. Thus, the objective of this research is to determine if arm and leg cycling can be used to improve walking ability in a post-stroke population. This outcome would directly impact the health and quality of life for those who have suffered a stroke.

The purpose of this study is to demonstrate the efficacy and safety of donepezil on the recovery of cognitive function in patients with stroke and to delineate the neurophysiologic mechanisms of the therapeutic effect of donepezil on the recovery of cognitive network using functional neuroimaging technique.

This main aim of the study is to investigate the changes in neurophysiological features after stroke, and its association with upper limb motor recovery, so as to establish a prognostic model for upper limb motor recovery after stroke. The investigators hypothesize that a combination of neurophysiological features measured by transcranial magnetic stimulation (TMS), high density electroencephalography (HD-EEG), functional magnetic resonance imaging (fMRI) and Diffusion Tensor Imaging (DTI) might be used as biomarkers to predict upper limb motor outcomes after stroke. The investigators also hypothesize that non-invasive brain stimulation strategies such as tDCS will more effectively improve motor outcomes as an adjunct to therapy, if tailored according to patient's predicted pattern of neural reorganization.

Interventional prospective randomized open blinded end-point (PROBE) single-center clinical trial on the evaluation of the efficacy, safety, feasibility, reliability, and cost-effectiveness of in-ambulance telemedicine for patients with suspicion of acute stroke.

The purpose of this study is to determine the safety of transcranial direct current stimulation in aphasia therapy in acute and post-acute stroke.
