Filter by:Stroke remains the 4th cause of death in Singapore and despite advances in medical care and rehabilitation, 40-50% of stroke survivors are left with permanent disability and reduced quality of life. Hand motor impairment is a very serious complication to every stroke survivor. These impairments include difficulty moving and coordinating the hands and fingers, which inhibits stroke patients from being able to perform daily functional tasks independently, resulting in a reduced quality of life. More than half of people with upper limb impairment after stroke will still have problems many months to years after their stroke. Therefore, improving hand function is a core element of rehabilitation where the aim is to recover and recruit the damaged neurons in the brain as soon as possible, within 3-6 months of the stroke as it thought to be the golden recovery period. In the hospital setting, every stroke patient will receive about 30 minutes to 1 hour of occupational therapy (OT) for functional training, including hand functional exercises. However, manpower constraints limited stroke patients to one OT session per day but they are encouraged to continuously practice on their own, which may cause patients to encounter difficulties without guidance and hence less motivated to perform. This proposed research aims to assess the efficacy and feasibility of the EsoGLOVE with Trigno Biofeedback (EMG sensors) in the inpatient rehabilitation setting through: 1. Understanding the ability of the EsoGLOVE with Trigno Biofeedback (EMG sensors) in providing CPM exercise and assisting stroke patients with completing hand functional tasks, eventually improves patients' motor function and neural recovery. 2. To generate evidence on this innovative device and further deploy it in clinical practice. A Health Technology Assessment (HTA) will be generated from this study to evaluate the cost-effectiveness of the intervention. The investigators hypothesize that EsoGLOVE with Trigno Biofeedback (EMG sensors) combined with hand rehabilitation will add additional benefits to stroke patients. It might have better hand functional outcomes than hand rehabilitation alone as it can allow the patients to conduct functional task training in both passive and active modes.
One of the most common complications in stroke patients is cognitive impairment. Cognitive impairment affects a large part of the life of stroke patients. However, the relationship between cognitive impairment and fear of falling in stroke patients has not been investigated in any study yet. Various treatment approaches have been developed to improve cognitive function. While some of these approaches focus on improving cognitive function, others aim to reach the maximum functional level with various compensation methods taught to the patient in the current cognitive situation. As a result of cognitive interventions, stroke patients' participation in daily life, adherence to treatment and quality of life increase. The aim of this study is to investigate the effects of cognitive interventions on motor performance, balance and fear of falling. This study will contribute to the literature by investigating these effects of cognitive rehabilitation.
The purpose of our study is to evaluate Vibrotactile Coordinated Reset stimulation (vCR) and its effects on motor ability within stroke patients. vCR will be administered with a device called the Vibrotactile (VT) Brain Glove. vCR is expected to provide patients with a non-invasive therapy to aid in recovery from a stroke. This study will include a dedicated sham arm that will aid in understanding true treatment effects from vCR.
Hypothermia with intrajugular cooling is a neuroprotective strategy that has been proven to minimize brain damage and maximize functional preservation in animal models of stroke. The purpose of this proof-of-concept study is to determine the safety and tolerability of intrajugular cooling in patients with acute ischemic stroke who are treated with mechanical thrombectomy.
The FloTrac/Vigileo is a minimal invasive device assessing flow based hemodynamic parameters by pulse contour analysis based on the radial artery pressure signal. This method gained popularity as it is minimally invasive compared to esophageal Doppler or pulmonary artery catheter insertion and provides continuous beat-to-beat data. The previous study with 110 patients found that that GDHT guided by stroke volume variation (SVV) using the FloTrac/Vigileo device was associated with a reduced length of hospital stay and a lower incidence of POGD in major abdominal oncological surgery. However, no difference was found in the incidence of postoperative complications between the two groups, lack of statistical power could be a limitation to demonstrate the true association. Therefore, further prospective trials are needed to address this issue. The use of early and efficient therapeutic strategies able to detect and to treat potential triggers of organ failures, such as tissue hypoperfusion, is particularly important. If hypoperfusion is not adequately managed, tissue hypoxia could occur, resulting from an impairment of the adaptive mechanisms of myocardial contractile function, under the influence of inflammatory mediators, and the peripheral tissues will then increase their oxygen extraction (O2ER). AS such, GDHT guided by O2ER may be appropriate to monitor GDHT strategies because it reflects the balance between oxygen delivery and consumption. Therefore, the investigators performed this single-center, randomized, controlled trial to investigate whether GDHT guided by SVV using FloTrac/Vigileo monitor and GDHT guided by O2ER would reduce incidence of postoperative complication and shorten the length of hospital stay, compared with a standard conventional fluid therapy in low-to-moderate risk patients undergoing major laparoscopic gastrointestinal oncological surgery.
The purpose of this study is to evaluate the efficacy and safety of intravenous doses of 3K3A-APC, a recombinant variant of human activated protein C (APC), in the treatment of acute ischemic stroke following treatment with thrombolysis, mechanical thrombectomy or both.
According to the "Chinese Stroke Report" released in 2020, the incidence of stroke in China is 1114.8/100,000, acute ischemic stroke (AIS) accounts for 70% to 80% of the total number of stroke population, and elderly stroke patients are up to 2/3. About 1/3 of stroke patients would experience post-stroke cognitive impairment (PSCI), which seriously affected patients' quality of life and survival time, and increases disease and economic burden. Therefore, early identification, assessment, prevention and intervention of PSCI, and improvement of patients' quality of life and prognosis have become the focus of clinical research. This is a prospective cohort study. We intend to: (1) continuously collect elderly AIS patients who will be admitted to the Department of Neurology, The Department of Rehabilitation and the Department of Gerontology of Shenzhen Second People's Hospital from 2022 year to 2024 year; (2) collect baseline and follow-up data, and build a prediction model for cognitive impairment in elderly AIS patients; (3) internal validation using Bootstrap model; (4) collect the data of the elderly AIS patients who will be admitted to Shenzhen Longhua District People's Hospital andShenzhen Longgang Central Hospital, and conduct external validation; (5) evaluate the predictive efficacy of the model.
The novel Amplatzer steerable delivery sheath (Abbott Vascular) is found to be safe and effective in performing LAAO procedure. However, the procedural outcomes have not been compared with the traditional non-steerable fixed curve sheath. In this study investigators aim to compare the outcome of patients undergoing left atrial appendage occlusion with the dual mechanism closure Amulet device using non-steerable fixed curve sheath versus a novel steerable sheath.
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.
