The aim of this study is to evaluate the effectiveness of continuous Theta Burst Stimulation added to mirror therapy on neglect associated with stroke.
NCT02892097
The purpose of this study is to test the effects of three different rehabilitation training sessions that combine non-invasive brain stimulation (transcranial direct current stimulation, tDCS) with arm rehabilitation training (repetitive task-specific practice, RTP) for individuals with unilateral spatial neglect following stroke. This study is designed to determine the effects of tDCS + RTP on the excitability in the brain, attention to the affected side, and arm movement ability.

Attention can be defined as the preparedness to rapidly and accurately respond to stimuli coming from the investigators environment and to effectively select between relevant and irrelevant information. According to a current model, visual attentional control is based on two separate groups of brain regions, so called brain networks. These networks control different attentional aspects (e.g., spatial/non-spatial attention) and they interact with each other. A disruption of these interactions can lead to attentional disorders such as hemispatial neglect. Patients with hemispatial neglect have difficulties directing their attention to the left visual field and they act as though the latter does not exist. To date, the interactions between the two attentional networks are poorly understood. The aim of this study consists in further clarifying different aspects of these interactions and their influence on visual perception in healthy participants and in patients with hemispatial neglect. Transcranial magnetic stimulation (TMS) will be the principal method applied in this study. TMS is a painless and non-invasive method, with which the activity of brain areas can be influenced temporarily. This allows us to draw conclusions regarding the functions and interactions of these brain areas. This study is designed to have a significant impact on the basic understanding of attentional control in the human brain and it can benefit the comprehension and treatment of attentional disorders, such as hemispatial neglect.

To find out if spatial neglect following stroke and brain injury can be reduced using guanfacine, a drug that was shown to improve neglect in two stroke patients in a previous pilot study (Malhotra et al, 2006). In this trial, the effects of guanfacine will be examined in a larger number of patients, and there will also be a systematic assessment of whether the drug is only effective in patients with particular patterns of brain damage.
NCT03605381
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.
NCT02945592
The presented study investigates standardized visual cueing in reading and visual spatial task as a treatment method for spatial neglect. In a randomized controlled design patients receive either cued reading and visual spatial tasks (intervention) or treatment which is unspecific to neglect (control). In the intervention condition, patients with left-sided neglect receive intense training, including reading and visual spatial task with standardized and adapted visual cueing by the therapist. Improvements in reading and visual spatial tasks lead to a reduction of cues by the therapist. Accordingly, the patient has to apply self-cueing over time in order to solve the task. For the control condition, all patients receive unspecific treatment without any standardized adapted cueing implemented by the therapist. To enhance the effectivity of cueing in reading and visual spatial tasks, the investigators additionally conduct parietal transcranial direct current stimulation (tDCS) in those patients without tDCS exclusion criteria (see exclusion criteria below). It is hypothesised that systematic and adaptive therapeutic cueing leads to a significant reduction of omissions of word and word parts in reading. UPDATE: No Add-on tDCS was performed since it was not applicable for our severly impaired patients due to the strict exclusion criteria of tDCS.
NCT00146952
The investigators propose to explore the hypothesis that vibrotactile channels for indicating spatial orientation can be exploited as a sensory prosthesis. The specific research applications will be used for guiding visual orientation, to provide alternative feedback to vision and vestibular signals for controlling balance, and for directional and lateralisation cueing in patients with neglect syndromes. The programme will study whether vibrotactile feedback improves performance and also if it speeds rehabilitation when used as an adjunct to conventional therapy.
NCT02258789
There is a lack of effective rehabilitation methods for visio-spatial neglect (VSN). By using virtual technology, a new method (virtual reality, VR method) has been created which focuses on stimulating attention networks: top down scanning training in a 3D game, combined with intense visual, audio and tactile bottom-up stimulation, also including visuo-motor training. Objective. To evaluate clinical and functional improvement in stroke patients with VSN, as well as before and after training with the new VR method Method:- An intense visio spatial scanning training, enhanced by directed visual, audio and tactile stimulation cues and feedback, also including visio-motor activation was designed in a VR game. The in-house developed software was based on the Tetris game. The VR method consists of an interactive 3D environment: a desktop computer, a monitor, 3D glasses and a force feedback interface. 15 patients with chronic (\>6 months) visio spatial neglect was included due to right-sided ischemia. A VR neglect test battery including a Posner task were repeated three times during a 5 weeks baseline before the training started (to establish the chronic state) and again after 15 hours training (3x1 h for 5 weeks). Evaluation of a new method for training attention after stroke causing visio spatial neglect. The method has been designed for home rehabilitation and is well suited for a tele-medicine approach. It was built with standard components and is easy to manufacture at a low cost. The idea is to give access to effective training, to make it available at the stroke unit with the possibility for the patient to loan it it at discharge for home rehabilitation. The concept of an all in one, easy-to-use device for testing, training and outcome evaluation should be beneficial These preliminare results has been promising and indicates that the RehAtt™ method could become an further developed into an effective and stimulating intervention tool that would lower rehabilitation costs and reduce tiresome travelling to hospitals for training.
NCT01735877
Hemi spatial neglect, or the tendency to ignore stimuli originating in a portion of the environment contra lateral to a cerebral lesion, can be a major source of functional handicap after stroke. The currently available treatments for unilateral neglect are scanning training, visual cuing approaches, limb activation strategies, visual imagery, tactile stimulation, prisms and sustained attention training.Mirror therapy improves the hand function in sub-acute stroke. Hypothesis: To evaluate the effectiveness of Mirror therapy in the management of stroke patients with unilateral neglect.
