Filter by:We hypothesize that: (1) gait stability will be increased when wearing an ankle-foot orthosis (plastic brace supporting the foot and ankle); (2) an attention demanding task will decrease gait stability and (3) the improvement in gait stability due to ankle-foot orthosis use will be greater during an attention demanding task.
The CSSPT study is a multi-center, randomized, double blinded, placebo-controlled secondary stroke prevention trial in China to determine whether the addition of folic acid and vitamin supplements will reduce recurrent stroke events and other combined incidence of recurrent vascular events and vascular death.
The Magnetic Resonance angiography (MRA) of supraaortic vessels is essential for the etiologic of stroke. However, the techniques usually used provide only static evaluation (degree of stenosis, occlusion) but not dynamic. An ultra-fast 3D MRA originally developed for the cardiac imaging, k-t blast (Broad-use Linear Acquisition Speed-up Technique) could be used to review the supraaortic vessels. This MRA offers the following advantages: short acquisition time, wide spatial coverage (of the thoracic aorta to the distal encephalic arteries), 3D spatial resolution and high temporal resolution. These qualities are even more optimal with a high magnetic field (3T). The high temporal resolution is interesting because it provides to repeat a volume every eight seconds and thus to have a dynamic evaluation of vascular filling and to assess the vascular supply of the infarcted territory. This sequence is classified as a 4D MRA.
The aim of this multicentric double blind study (randomized study) is to demonstrate the relationship between the amount of rTMS and the efficacy in the treatment of upper extremity motor deficits of stroke patients.
The primary objective of the study is to assess the safety and tolerability of Human Placenta-Derived Cells (PDA001) at 3 different dose levels versus placebo (vehicle control) administered intravenously in subjects following ischemic stroke. The secondary objective of the study is to assess the effect of PDA001 on improvement in clinical function following ischemic stroke.
Novel stroke rehabilitation approaches, such as task-specific training (TST), have shown promise in improving stroke recovery components such as basic mobility and activities of daily living; however, evidence suggests these improvements are not generalized and transferred to home, community, or work settings, and usually do not impact overall participation outcomes. Further, these treatments are very intense, with total treatment times as high as 30 to 60 hours, making them clinically or economically unfeasible in many settings. In contrast, approaches incorporating cognitive strategy training have shown great promise to not only improve functional activity performance in people living with stroke, but also to facilitate generalization and transfer beyond the clinical setting, and to do so in 10 to 15 treatment hours. Cognitive Orientation to daily Occupational Performance (CO-OP) is an established treatment approach that uses cognitive strategies in combination with TST. Evidence from other research groups and findings from our own participant interview data indicate that the approach may be even more effective if introduced much earlier in the rehabilitation process, however, CO-OP has not yet been tested in this sub-acute population. Therefore, the specific project goals are: 1. To refine the CO-OP treatment approach for use with people less than three months post stroke; 2. To evaluate, in a Phase II clinical trial, the preliminary efficacy of the refined protocol compared to standard occupational therapy on immediate and longer-term skill performance and participation; 3. To determine effect sizes for power calculations for a future Phase III clinical trial to test the new protocol versus contemporary treatment. The research approach consists of Part 1, Protocol Refinement, and Part 2, Exploratory Phase II Clinical Trial.
In Israel approximately 16,000 people have a stroke each year. Most of these people suffer from weakness or paralysis of half of their body which leads to difficulties performing basic activities of daily life (BADL) such as dressing and walking. Due to the stroke, these individuals need to undergo intensive rehabilitation. After rehabilitation, physical activity has been strongly recommended to maintain their functional level which was achieved during rehabilitation. In addition regular physical activity can prevent secondary condition However, recent findings suggest that people with stroke do not perform enough physical activity with their upper and lower extremities. The use of Virtual Reality (VR) for rehabilitation has been found to have potential for encouraging active purposeful movement. Many researchers have assessed the feasibility & usability of different VR systems and environments for individuals with stroke. Costly VR systems in addition to off-the-shelf video game consoles (e.g. Sony PlayStation EyeToy, Nintendo Wii) have been found to have great potential to encourage active purposeful movement. However, to date, only a limited number of studies have investigated the effectiveness of VR therapy post-stroke. Since physical activity is important after stroke and the fact that individuals with stroke are not participating sufficiently in physical activity, I suggest to carry out this study. The overall aim of this study is to assess the effectiveness of using novel technology of VR therapy to promote the participation in daily physical activity of individuals with stroke. A 'Community based' VR program will be compared to a traditional therapy program in promoting daily physical activity of the lower and upper extremities. It is hypothesized that the VR intervention will be more efficient than the traditional therapy in promoting physical activity (walking and use of the weak upper extremity).
Stroke, a leading cause of disability in the aging population, increases the risk for diabetes, subsequent stroke recurrence, and cardiovascular disease complications. The downsizing of private and federal health care resources, along with the anticipated increase in stroke rates as our population ages, mandate that alternative strategies be developed to reduce the public health burden of stroke. This pilot study may facilitate our knowledge of the timing of paretic leg muscle atrophy, fiber type shift, and the progression of worsening of glucose tolerance after stroke. Knowledge of the skeletal muscle changes occurring in the sub-acute stroke period is essential to create new guidelines incorporating exercise rehabilitation, much like cardiac rehabilitation, in order to facilitate and improve the health care of veteran stroke survivors.
The purpose of this study is to compare the improvement in ankle control and brain activation in subjects with stroke resulting from two different forms of telerehabilitation: tracking training, emphasizing accurate movements, versus movement training, involving simple movements. Hypotheses: 1. The Track group will show greater improvement in ankle range of motion compared to the Move group. 2. The Track group will show greater improvement in ankle tracking accuracy and greater changes in fMRI (increase in relative volume of activation for ipsilesional sensorimotor cortex, increase in laterality index, and decrease in blood-oxygen-level-dependent (BOLD) signal intensity index) compared to Move group. 3. The Track group will show greater improvement in tracking accuracy at an untrained joint (knee) compared to the Move group. 4. The Track group will show greater improvement in standing balance. 5. The Track group will show greater improvement in walking speed and ankle dorsiflexion during gait compared to the Move group.
The purpose of this study is to assess the safety and tolerability of allogeneic adult mesenchymal bone marrow cells administered intravenously to patients with ischemic stroke.
