Filter by: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.
The presence of a damage to the central and / or peripheral nervous system resulting from diseases of a different nature (such as, Multiple Sclerosis, Parkinson's disease, dementia, head trauma, stroke, epilepsy or other neurological syndromes) is commonly cause of both physical than mental disability. The evaluation of certain domains may be more difficult so, specific assessment tools are necessary to analyze them.
Aim of the study is to translate and culturally adapt the modified Barthel index into Urdu language and to investigate the reliability and validity of this scale in Urdu speaking Stroke population for performance evaluation. Also check its correlation with Functional independence measure and Katz index of Activities of Daily Living.
According to the definition proposed by the World Health Organization, "stroke is rapidly developing clinical signs of focal (or global) disturbance of cerebral function, with symptoms lasting 24 hours or longer, or leading to death, with no apparent cause other than of vascular origin". Difficulty in walking is present in approximately 80% of stroke survivors. 25% of stroke survivors even after getting rehabilitation have residual gait impairments requiring full assistance after hospital discharge resulting in difficulties in performing basic activities of daily life. Approaches to gait rehabilitation are different based on different models of motor physiology and disease recovery, but most of the approaches are targeting motor impairments during straight walking only as opposed to adaptive walking ability . In order to decrease health care burden effective rehabilitation and prevention is necessary. Multidisciplinary care dedicated for stroke leads to higher independence rates. Conventional gait training regimes including linear parallel bar based gait training and treadmill based gait training protocols do not usually target the angular or rotational component of locomotion. Current study will focus on Unilateral Step Training using a traditional treadmill. This would provide a targeted gait training tool to reduce the risk of fall, improve gait and turning ability and functional activity eventually resulting in greater community participation and involvement in occupational activities. Such an approach could be effective in providing an early targeted and intense training environment similar to task-specific training in contrast to conventional method.
Stroke is one of the leading causes of disability globally. Stroke survivors generally require lifelong support from family caregivers. The abrupt onset of stroke and associated physical and cognitive impairments result in a series of complex and demanding interactions between family caregivers and stroke survivors. More than 40% of stroke caregivers develop depressive symptoms over time. The depression of family caregivers negatively impacts their physical health and caregiving role and directly affects the mental health and recovery of stroke survivors. Thus, effective strategies for stressful caregiving situations are urgently needed. As postulated in the relational/problem solving model of stress, problem-solving coping is a cognitive behavioral process that can enhance caregivers' well-being by changing caregiving situations and/or changing their negative emotional stress responses to stressful situations into positive responses. In view of the influence of negative emotions on the cognitive process of an individual, integrating perspective taking as a cognitive reappraisal strategy into the training of problem-solving coping skills may potentially improve the psychosocial well-being of family caregivers. This mixed method study aims (1) to examine the effects of a emotion-centered problem-solving intervention on the depressive symptoms, problem-solving coping, emotion regulation, caregiving competence, and health-related quality of life of stroke caregivers and on the physical functioning of stroke survivors; (2) to explore the mediating effect of emotion regulation and problem solving coping on caregivers' depressive symptoms, caregiving competence, and health-related quality of life and on stroke survivors' physical functioning; and (3) to understand how intervention influences depressive symptoms from a family caregiver's perspective. A total of 178 family caregivers will be recruited from various non-government organizations and nurse clinics for stroke patients of the Hospital Authority. Participants will be randomly allocated to the intervention group (IG) and control group (CG). Caregivers in the IG will receive an emotion-centered problem-solving intervention adopting a "shared problem, shared action plan" approach, whereas the caregivers in the CG will receive stroke-related education. Outcomes will be measured at baseline, 12 and 36 weeks after study entry. This study makes the first attempt to develop an emotion-centered problem-solving intervention and examine its effectiveness in the context of stroke caregiving. The findings will advance our understanding of emotional regulation and problem-solving coping strategies for reducing the depressive symptoms of stroke caregivers, ultimately providing a culturally sensitive medical-social service direction for the delivery of community-based rehabilitation services to stroke families.
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.
In the literature, it has been observed that traditional balance training (TBT) and robot-assisted walking training (RAGT) in stroke patients stimulate the balance mechanism by supporting the spinal muscles symmetrically and functionally. However, it is seen that there is no clear protocol for RAGT in the chronic period. Combined RAGT and TBT approaches over ten weeks have been shown to be more effective than TBT alone for the acute and subacute period. However, there is no definite expression for chronic period effects. No study was found in the literature in which an objective measuring device was used for balance assessment of patients receiving TBT and RAGT. If changes are detected between the two treatment groups in balance education in stroke patients as a result of objective evaluation, our study will lead to the necessity of including these changes in the treatment. Considering the effect of balance on activities of daily living, we believe that objective evaluation of the changes in balance after TBT and RAGT in stroke patients and shaping the treatment according to the evaluation results will contribute to the literature.
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.
