Filter by:The researchers designed a software based on a head-mounted displays for virtual reality (HMD-VR) to evaluate the reaction time to stimuli presented at right or left visual field. The study will recruit 100 stroke patients with hemisphere lesions (50 patients for right and left each) and 100 age-matched healthy controls. The participants will conduct a simple reaction time task in VR, with stimuli designated in the left or right hemi-field. The stroke patients will also received traditional tests for hemi-neglect. Test-retest reliability of the assessment will be conducted in a subset of the control group. The stroke patients will be followed in 3-4 weeks.
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.
Fatigue is a common condition after an individual has a stroke. While the negative impacts of post-stroke fatigue are well known, the knowledge of the causes of post-stroke fatigue and effective treatments for post-stroke fatigue are lacking. This small study will investigate the possible benefits of transcranial direct current stimulation (tDCS), which uses small electrical currents supplied by a 9-volt battery, on post-stroke fatigue and investigate tDCS' possible anti-inflammatory effects.
Emergency department overcrowding is a major challenge in medicine, leading to a delay in diagnosis and treatment for the patient due to long waiting times. This is very relevant for diseases like acute stroke and other emergencies. The Advanced Mobile Stroke Unit is an ambulance equipped with additional devices to diagnose and treat patients at the emergency site. Patients with less severe conditions can be diagnosed and safely left at home. The objectives of this project are to investigate whether the Advanced Mobile Stroke Unit compared to a normal ambulance enables more accurate triage of patients (treatment at home vs hospital vs specialist vs A&E). The Advanced Mobile Stroke Unit ambulance will be used in a random order of weeks and this will be compared to weeks with normal ambulances. The study will be carried out by the East of England Ambulance Service NHS Trust in collaboration with the East Suffolk and North Essex NHS Foundation Trust in the East of England. The project is a collaboration with Saarland University, Germany,
Aims: Assess the usability of OnTrack Tools, a clinician facing interface to manage stroke survivors using the OnTrack rehabilitation system. Background: Arm disability is a common problem after stroke that can lead to loss of independence, it affects ~450,000 people in the UK. Repetitive activity is critical for recovery but research shows people can struggle with intensity and keeping track of progress. The OnTrack system being developed at Imperial College London is a potential solution to this problem. Intervention: The OnTrack system consists of two software applications, OnTrack App - used by patients, and OnTrack Tools - used by clinicians. OnTrack Tools pulls data generated by the OnTrack App and enables the monitoring of clients' arm activity, and management of goals and educational content. The software is used to inform selfmanagement coaching by helping therapists understand more about how and when patients use their affected arm between treatment sessions. Design and methods: This study will assess the usability of the OnTrack Tools component of the system. The study will recruit stroke therapists from Imperial College Healthcare NHS Trust to provide feedback on the experience and usability of OnTrack Tools' graphical user interface (GUI). The study will be divided into three progressive cycles of testing, feedback and iteration. Each cycle will see participants individually completing specific tasks related to system navigation and the management of patients under simulation. Participants will complete outcome measures and take part in focus groups. Researchers will analyse and use the feedback to improve the GUI ready for the next testing cycle. Patient and public involvement: The project team includes a PPIE group of stroke survivors who oversee the project and help us with public facing documentation. They are members of the research team and are reimbursed for their time and travel, according to INVOLVE guidance. Dissemination: Results of the study will be written-up for technical reporting and publication. Participants will be provided with a summary of results at the end of the study. The study team will be providing general updates on the progress of the study via their social media channels (e.g. Twitter @OnTrackRehab @ImperialIGHI @HelixCentre).
The present study aims to investigate the therapeutic potential of a high definition transcranial direct current stimulation protocol, stimulating frontal and cerebellar areas boosting the cognitive and motor recovery of stroke population.
Investigators propose a research design protocol to evaluate the efficacy of laser acupuncture in improving shoulder pain and improving shoulder function recovery after stroke.

Stroke is the main cause of disability and the second main cause of dementia. Approximately 21.5% of patients develop dementia within 4 years after stroke. The main clinical manifestation of dementia is memory and cognitive impairment. At present, acetylcholinesterase inhibitors and NMDA glutamate receptor antagonists, were used for dementia treatment, but those drugs have limited efficacy. Exosome is an extracellular vesicle from the endosomal, size range from ~40 to 160 nm (average ~100 nm). It contains many cells including DNA, RNA, fat, and metabolites, as well as cytoplasm and cell surface proteins that play a role in regulating intercellular communication. Some studies believe that exosomes in the circulation are an ideal marker to reflect the pathological progress and recovery of stroke, and play a key role in the reorganization of tissues and the progress of neurodegeneration after stroke. Our previous studies have known that acupuncture can increase the long-term potentiation of hippocampal CA1 in rats with ischemic stroke, and improve learning-memory and neurological function. Therefore, the purpose of this study is to explore the role of acupuncture-induced exosome in the treatment of post-stroke dementia.
