Filter by:Information regarding the likely progress of post-stroke symptoms is vitally important to stroke survivors to allow them to plan for the future and to adjust to life after stroke. Moreover, the prevalence of morbidity secondary to stroke is of central importance to Health Professionals to understand the prognosis of the disease in the patients under their care. Additionally, it will also allow commissioners of care, planners and third sector organisations to adapt to and answer the needs of a post-stroke population. Currently, the data collected by national audit programmes are concentrated on what can be termed 'process or process of care' data. The utility of these data are in the ability to audit the care received by stroke survivors on stroke units against evidenced standards for care, thus ensuring evidence based practice. Nevertheless, process of care is only one form of measuring stroke unit care and the audit programmes collect some limited functional status data, data relating to risk-factor co-morbidities and treatment received data. Therefore, the scope of this study is to build on the minimum data set currently collected and to collect post-stroke data in domains not currently collected. The International Consortium for Health Outcomes Measurement (ICHOM) takes important steps to collect data outside of process of care data such as a Patient Reported outcome data in their minimum outcome data set for stroke [currently under review].. Nevertheless, the ICHOM doesn't currently advocate the specific collection of data relating to cognitive impairment or emotional problems secondary to stroke. It is in these important aspects that this study will augment the data set currently advocated by ICHOM to collect data in the areas of cognitive impairment and emotional problems secondary to stroke. Therefore, the aim of this study is to quantify the prevalence of morbidity at six months post-stroke.
This study investigates a new technology to assess the structure and function inside the eye. Retinal imaging of subjects with inner and outer retinal defects to detect areas of abnormal structure and function compared to other visual function tests.
The purpose of this research is to assess the efficacy of a visual training task on reducing the size of a visual field deficit caused by brain damage in adults, and its ability to improve visual functions in this patient population.
This study evaluates a novel collision warning device to help people with severe vision impairment or blindness avoid collisions with obstacles. The main hypothesis to be tested is that the device reduces the number of collisions with obstacles in everyday activities.
The purpose of this Study is to determine whether non-invasive transcranial direct current stimulation (tDCS) is effective in increasing rehabilitation effects after stroke in visual Cortex.

The purpose of our study is to explore the efficacy of combination of brain stimulation with visual rehabilitation in patients with visual field loss resulting from brain lesions. It is shown that the effect of sensorimotor training of hand can be enhanced in patients with stroke using brain stimulation. We decided to explore this combination for visual field loss because visual dysfunction following brain lesions is considered intractable. We hypothesize that combination of noninvasive brain stimulation, in the form of transcranial direct current stimulation (tDCS), with visual rehabilitation would have greater efficacy than visual rehabilitation alone.
