Stroke is the leading cause of premature death and disability, and early recognition and treatment of dysphagia is fundamental to stroke management. Early and full tube feeding in the acute phase of stroke helps to address nutritional problems resulting from dysphagia and impaired consciousness and helps to reduce morbidity and mortality and poor outcomes. Current guidelines for acute stroke management do not address the goal of tube feeding of enteral nutrition for energy and protein. In the treatment of acute stroke, there is a strong global focus on pharmacological thrombolysis or mechanical thrombolysis, with nutritional interventions being a less explored topic. Real-world evidence on large samples, feeding attainment and outcomes, and nutrition in the acute phase of stroke is lacking in China . The aim of this study was to understand the current status of nutritional therapy in stroke hospitalization in neurology and its impact on prognosis nationwide, and to improve the standardized management process of enteral nutrition therapy in the acute phase of stroke.
The purpose of this proposal is to use novel video-based movement tracking technology to measure gait quality after stroke - in the home. Current rehabilitation practice assesses walking in the highly controlled 'ideal' clinical environment. The implicit assumption by clinicians and researchers is that the way people walk in the clinic (their best capacity) reflects the way they walk in the real-world (true performance). With advances in computer vision and development of pose estimation algorithms, it is now possible to directly measure how people are walking in their homes. It is critical that researchers apply this technology to examine the basic assumptions that underlie current rehabilitation practice. Here, a video-based pose estimation workflow will be used to 1) contrast the gait patterns of persons post-stroke as observed in-clinical vs. in-home settings, and 2) map the rate of deterioration of clinically-derived walking improvements, in the home. This methodology has been used to accurately measure gait kinematics in people with stroke as they walk in laboratory, however this study now seeks to use these methods to record people with stroke as they walk in their natural home environments. The ultimate outcome of this project will not only be freely-available video-based workflow modified for home-based gait assessments, but also preliminary data revealing how people with stroke walk in the real world.
Robotic lower limb exoskeletons aim to improve or augment limb functions. Automatic modulation of robotic assistance is very important because it can increase the assistive outcomes and guarantee safety when using exoskeletons. However, this automatic assistance adjustment is challenging due to person-to-person and day-to-day variations, as well as the time-varying complex human-machine-interaction forces. In recent years, human-in-the-loop optimization methods have been investigated to reduce participants' metabolic costs by providing personalized assistance from robotic exoskeletons. However, metabolic cost measure is noisy and the experimental protocol is usually relatively long. In addition, the influence of exoskeleton control on this human state in terms of energetic cost is unclear and indirect. More importantly, the optimization by reducing metabolic cost is found to affect human gait patterns and cause undesired outcomes. In this study, new evaluation measures other than metabolic cost will be investigated to optimize the assistance from a powered hip exoskeleton based on a reinforcement learning method. It is hypothesized that the new reinforcement learning-based optimal control approach will produce personalized torque assistance, reduce human volitional effort, and improve balance and other performance during walking tasks. Both participants without and with neurological disorders will be included in this study.
Patients undergoing cardiac surgery have a higher risk of postoperative stroke than patients undergoing non-cardiac surgery. Our ability to detect postoperative stroke in this population lags behind other postoperative complications which impacts outcomes for patients eligible for medical intervention. Screening tools have been successful in detecting prehospital stroke with good accuracy, but these tools have not been validated in a postoperative setting. The aim of this pilot study is to use determine the feasibility of using prehospital stroke scales in a post-cardiac surgery population, identify barriers for scale completion, and determine non-stroke factors that may affect screening scores.
A study to Evaluate the Efficacy and Safety of Renexin CR in patients with Acute Non-cardioembolic Ischemic Stroke
Aphasia is an acquired impairment of language, that commonly results from damage to language areas in the brain (typically the left side of the brain). This impairment is seen in many aspects of language, including understanding, speaking, reading and writing. It is estimated that about 2 million individuals are currently living with aphasia in the United States. Further, about 200,000 Americans acquire aphasia every year (National Aphasia Association, 2020). Aphasia poses significant impact on the affected individuals and their families. Behavioral treatments that target language deficits have been shown to enhance overall communication skills and life satisfaction among individuals with aphasia. Although there is evidence that suggests that treatment is efficacious for individuals with aphasia, the extent of improvement long-term coupled with the neural patterns among those individuals are largely unknown. The current study aims to investigate the efficacy of language-based treatment and its corresponding neural patterns.
One hundred participants with acquired brain injury (ABI) will be included in a randomized controlled trial, with one group playing a commercially available VR game and the control group doing activities in their everyday as cognitive training. The trial aims to investigate how VR can affect processing speed in the ABI population, and if these effects can transfer into everyday activities. The training will be performed in the participants homes, with assistance provided by the project group via phone or video conference. The training period will last five weeks. Participant's cognitive functions will be measured with questionnaires and neuropsychological tests at the start of the training period, at the end of training and sixteen weeks after the start of the intervention. In depth experiences with VR as a training method will be gathered through performing focus group interviews with some of the participants from the VR group, in addition to self-reported questionnaires from all the participants.
The objective of the study is to evaluate the effect of engaging in adaptive sports for individuals who have had a stroke. The study is cross-sectional, participants with stroke will be recruited and divided into two groups: the first group composed of individuals with stroke who regularly participate in adaptive sports; and the second of individuals with stroke who do not regularly participate in adaptive sports. The two groups will have to be similar in terms of demographic variables (age, gender, time since beginning of stroke). A series of parameters will be tested, on one occasion for each participant. The two groups will then be compared to one another.
The purpose of the study is to compare the effectiveness of virtual reality and mirror therapy in stroke patients. Different studies has been done to find out the best therapy for stroke patients. Use of virtual reality in medical field is becoming more popular now-a-days. Different devices and applications are available to treat various conditions. Research has been done to find the clinical applications of virtual reality for upper limb motor rehabilitation in stroke. in another study, mirror therapy with bilateral arm training was used for hemiplegic upper extremity motor functions in patients with chronic stroke. After doing literature review, it was found that no research has been done to compare the effectiveness of mirror therapy with virtual reality in improving motor function of upper limb of stroke patients. So, In this study these two therapies are compared. For virtual reality Oculus Quest 2 has been used. Patients were allowed to use beat saber game on Oculus.
