Filter by:Investigating the interrelation of stroke and sleep-disordered breathing (SDB) is of major importance. First because of the high occurrence rate of stroke and the fact that it is a frequent cause of long-term disability in adulthood. Second because SDB (obstructive, central and mixed forms) affects more than 50% of stroke survivors and has a detrimental effect on clinical stroke outcome. Third, spontaneous and learning-dependent sleep-associated neuroplasticity may be affected by SDB following stroke worsening stroke rehabilitation. Therefore, it is crucial to investigate whether early treatment of SDB with Adaptive Servo-Ventilation (ASV), the treatment device of choice to treat obstructive, central and mixed forms of SDB, has a beneficial effect on the evolution of the lesion volume and on clinical stroke outcome. To this end, the investigators recruit and prospectively follow 3 groups of patients with ischemic stroke over 1 year. During the first night after hospital admission due to acute stroke, nocturnal breathing is assessed by means of a respiratory polygraphy. Patients with significant sleep disordered breathing, defined as an Apnea-Hypopnea-Index (AHI) > 20/h, are randomized to ASV treatment or no treatment (sSDB ASV+ or sSDB ASV-). ASV treatment starts the second night following hospital admission and ends 90 days later. Stroke patients without SDB (AHI < 5 / h) serve as a control group (no SDB) to observe the evolution of the lesion volume and stroke outcome without the additional burden of SDB. Lesion volume one day after hospital admission due to acute stroke (after potential lysis therapy) measured by Diffusion Weighted Imaging will be subtracted from lesion volume measured by T2-weighted volumetry assessed 90(+/-7) days following stroke and compared between patients with and without ASV treatment (sSDB ASV+ and sSDB ASV-) as well as patients without SDB (no SDB). Short- and long-term clinical stroke outcomes are assessed by clinical scales and questionnaires 4 to 7 days, 3 months and 1 year following stroke. Cognitive outcome is assessed during hospitalization (within the first week following stroke) and after the treatment period of 90 days by neuropsychological tests assessing attention and memory. In addition, baseline assessment of physiological parameters such as blood pressure and endothelial function/arterial stiffness are assessed during the first weeks following stroke and at the end of the treatment period, i.e. approximately 90 days following stroke.
The objective of this study was to: compare the training and maintenance effects of 3 balance training programs (2 kinds of exergame systems and 1 conventional weight-shifting training program) on cognitive function of subjects with chronic stroke.
The investigators would like to determine if remote ischemic leg preconditioning in healthy volunteers improves cerebral vasomotor reactivity as measured by breath holding and transcranial doppler vasomotor reactivity.
The ultimate goal of this project is to develop a functioning and clinically feasible method for restoring function to motor-impaired stroke survivors. This ultimate goal will be approached through two different means. The first method is to develop a functioning brain-computer interface that operates based on cortical activity ipsilateral to an intended movement on the motor-impaired side of the body. And secondly, to develop new methods of rehabilitation that involve stimulating peripheral muscles based upon cortical activity ipsilateral to intended movements. Finally, the study seeks to assess changes in functional connectivity as a result of using a BCI device.
The purpose of this study is to assess the effect of continuous positive airway pressure (CPAP) on functional outcome in patients with acute stroke, the investigators conducted a sham-controlled, double-blind pilot trial during inpatient rehabilitation. Patients with acute stroke were recruited and randomly assigned to auto-titrating or sham-CPAP during their rehabilitation stay.
The purpose of this study is to determine the treatment effects of sequential combination of aerobic exercise and cognitive training on cognitive function, physiological markers, daily function, physical function, social participation and quality of life in stroke patients with cognitive decline. The investigators hypothesized that: (1) sequential training protocol can improve outcome measures compared to single mode of training; (2) these treatment effects will retain at 6-month follow-up.
To investigate the risk of major bleeding (including gastrointestinal and intracranial bleeding episodes) among new users of low-dose acetylsalicylic acid (ASA) in clinical practice
Muscle alterations and modifications passive biomechanical properties that occur on a spastic muscle contribute to functional disorders involved in spasticity. Botulinum toxin (TB) A is the reference treatment of the focused spasticity, and muscle source structural and biomechanical changes, very little studied in humans, especially since it is not one possibility of easily and reliably paraclinical assessment injections consequences.
Transient Ischaemic Attack (TIA), also called 'ministroke' is characterised by shortlasting symptoms that generally do not cause permanent damage. 'Minor stroke' is a term used to describe a stroke with mild and nondisabling symptoms. TIA and minor stroke patients account for more than half of all cases of stroke and they are at a higher risk to suffer a major stroke. Currently, management of TIA/minor stroke patients is mainly focused on identifying and reducing risk factors for a later stroke. However, people after a TIA often have limited access for further specialist support from stroke-specific rehabilitation services. Although there is variability in the level of recovery and severity of symptoms after TIA and minor stroke, there is evidence that these patients may experience difficulties that affect their quality of life including anxiety and depression. This study aims to develop, tailor and target the delivery of a time-limited group intervention that offers educational, psychological and social support for people following TIA and minor stroke. A qualitative study (Phase 1) will be conducted with service users and experts working with people with TIA/minor stroke to develop the psychoeducational intervention. Following this, we will conduct a feasibility randomised controlled trial in one centre (Phase 2) to explore whether this group psychoeducational intervention for people after TIA and minor stroke carers is acceptable and to determine the feasibility of the proposed evaluation and the sample size needed in a definite trial.
The purpose of this study is to examine if high intensity interval training after stroke is more effective than standard care to increase maximal oxygen uptake, reduce known risk factors for recurrent stroke and improve function.
