Filter by:The objective is to validate the algorithms for movement analysis that were developed previously in healthy participants, in a small study with stroke patients. Stroke subjects will be measured while performing tasks like walking, sitting and standing while wearing light-weight inertial measurements units (IMUs) incorporating 3D accelerometers, 3D gyroscopes and surface electromyography. During the measurements subjects will be recorded on video that serves as ground truth when validating the implemented algorithms for movement analysis. A face blurring program will be used for all video footage.
This study will be observe the effect of Task-oriented training on the dexterous movements of hands in hemiparetic post-stroke patients. Patient will be recruited that meet the inclusion criteria, with unilateral hemiplegia referred by Neurophysician having stroke for the first time, between age 47-70 year, both males and females, score of spasticity for upper extremity (shoulder, elbow) below and equal 2 based on the Modified Ashworth Scale (MAS), ability to comprehend simple instructions (Mini-Mental State Examination with a minimum score > 24), Brunnstrom stages ≥ 4, not submitted to other upper-limb rehabilitation programs during the participation in this study. The individuals with recurrent stroke episodes and transient ischemic attack, other neurological diseases (Parkinson's disease, multiple sclerosis,), hemineglect, no sitting balance and comorbidities are excluded. Outcome measures used are FuglMeyer assessment scale (wrist and hand) and Wolf motor function test for upper extremity while Barthel index to assess the activities of daily living. All procedures will perform by taking informed consent. All Ethical standards for both patient and institution will be followed. After collecting data, will apply Shapiro Wilk test to check the normal distribution of data. For analysis use SPSS version 25
With contemporary lifestyle changes and global aging, it is important yet unknown how stress interacts to post-stroke outcomes. This proposal aims to study the link between the stress-responsive FKBP51-related pathways and neural plasticity after stroke, elucidating FKBP5 gene polymorphisms and blood FKBP51 regulation in relation to brain excitability and functions, understanding the effects of transcranial direct current stimulation, and characterizing brain mechanisms for individualized early rehabilitation after stroke.
Neurogenic dysphagia occurs with disruption of neurological systems or processes involved in the execution of coordinated and safe swallowing. It is common in patients with neurological diseases, in particular in patients treated in Intensive Care Units (ICU) who are intubated (up to 62%) and / or tracheotomised (up to 83%). Dysphagia is one of the most common and most dangerous symptoms of many neurological diseases. In addition, neurogenic dysphagia can have a significant impact on quality of life, medication efficacy, and malnutrition. Dysphagia is currently treated conservatively on evidence-based exercises, individually adapted to each patient. In the recent years pharyngeal electrostimulation has been established and shown a positive impact on outcome. In fact, this type of therapy has not only become an addition to the existing therapy, but an important alternative for patients difficult to treat by other means. The Phagenyx® is a medical device, which has lately been used more frequently in multiple hospitals for treatment of neurogenic dysphagia. For nearly two decades pharyngeal electrostimulation has been further developed and optimised. This therapy initiates changes in the swallowing motor cortex through neuroplasticity as well as local changes in peripheral sensory architecture associated with swallowing. Bath and colleagues (2020) recently reported the efficacy of pharyngeal electrostimulation (Phagenyx®) in various neurological conditions. As a result, of current published studies, the use of pharyngeal electrostimulation probe, in selected patients, with neurological diseases with moderate to severe neurogenic dysphagia will be evaluated. This trial will initially start as quality assurance project with the aim to extent it into a monocentric based register study. The Investigators aim to validate the effectiveness of pharyngeal electrostimulation for the treatment of moderate to severe neurogenic dysphagia by systematically recording specific dysphagia-relevant parameters. At present, it is still uncertain to what extent patients with neurogenic dysphagia in the context of a non-acute neurological disease could benefit from this method. The research questions: Does the use of the pharyngeal electrostimulation probe have an influence on the outcome of dysphagia in patients with moderate to severe neurogenic dysphagia? How long after therapy, can the use of the pharyngeal electrostimulation probe lead to oral food intake and/or removal of a tracheal cannula?
The study is a prospective, multicenter, randomized, double-blind, placebo-controlled study evaluating the safety and efficacy of tirofiban in combination with intravenous thrombolytic therapy with alteplase in acute ischemic stroke
The aim of the biomedical research is to evaluate the changes of body position management during standing and walking for stroke patients, using innovative training methods during the rehabilitation.
A brain-computer interface (BCI) decodes users' behavioral intentions or mental states directly from their brain activity, thus allowing operation of devices without requiring any overt motor action. One major modality for BCI control is based on motor imagery (MI), which is the mental rehearsal of the kinesthetics of a movement without actually performing it. MI-based BCIs translate motor intents into control commands for external devices. A major challenge in such BCIs is differentiating MI patterns corresponding to fine hand movements of the same limb from non-invasive EEG recordings with low spatial resolution since the cortical sources responsible for these movements are overlapping. In this study, the investigators hypothesize that neuromuscular electrical stimulation (NMES) applied contingent to the voluntary activation of the primary motor cortex through MI can help differentiate patterns of activity associated with different hand movements of the same limb by consistently recruiting the separate neural pathways associated with each of the movements within a closed-loop BCI setup. This is expected to be associated with neuroplastic changes at the cortical or corticospinal levels.
Post-stroke spasticity in the lower extremity affects balance and gait, leading to decreased mobility and functional independence. Therefore, effective intervention for reducing spasticity is crucial in stroke rehabilitation. Recently, neurodynamics, though originally designed for pain management in orthopedic patients, has also been applied for treating spasticity in patients with neurological disorders. However, previous studies focused mainly on treating the upper extremity spasticity, but not on lower extremity spasticity, and not on possible neurophysiological changes. The present study aims to investigate the immediate effects of neurodynamics in reducing lower limb spasticity and neurophysiological changes in people with chronic stroke.
Thrombus shedding in patients with atrial fibrillation (AF) can lead to cerebral artery embolism. Stroke caused by AF is very dangerous, which not only threatens the life of patients, but also seriously affects the quality of life. This study aims to explore the biomarkers of stroke in patients with AF by integrating proteomics and metabolomics data, and establish the network relationship of stroke in patients with AF, so as to reveal the molecular mechanism of stroke in patients with AF.
In the current project, primary health care patients with mental illness such as anxiety, depression, fatigue or sleep disorders will be followed. The study includes both health conversations with the health curve as a systematic work with lifestyle habits, and the biochemical risk marker copeptin with a focus on improved lifestyle habits and the development of cardiovascular complications. Participants will be followed up at 12 and 24 months with renewed health interview including the health curve and blood sampling. National registries will be used for a, up to 20 year long follow-up regarding cardiovascular complications and mortality.
