Active clinical trials for "Stroke"

Robot-assisted training (RT) devices developed to date have a significant impact on stroke rehabilitation. Several research groups have developed the robotic devices and examined their efficacy on improving upper limb function after stroke. All these robotic devices have been applied in stroke rehabilitation and their efficacy are evaluated, but the scientific evidence for the mechanisms of RT-induced recovery, the optimal treatment intensity, and the impact on physiological responses is still lacking. This trial is to examine (1) the immediate effects of treatment intensity in RT on sensorimotor impairments and functional performance in patients with subacute stroke; (2) the long-term benefits of treatment intensity in RT by conducting a 6-month follow up evaluation; and (3) the effects of RT on cortical/movement reorganization as well as on the physiological markers of inflammation, oxidative stress, and erythrocyte deformability. These overall findings will help better understanding of the efficacy of RT on functional outcomes, brain and movement reorganization, and physiological markers.

Early childhood injuries such as perinatal (around birth) stroke are devastating because the child lives with the problem for life, typically close to a normal lifespan. One 'opportunity' presented by a brain injury early in life compared to later in adulthood is that the young brain is much more plastic (malleable) and receptive to interventions. This is particularly true for neural circuits that are still under development. We will test the hypothesis that early (<2 yr old), intensive leg training will improve walking more than no training or training at >2 yr old. We will further determine the changes induced by training in motor and sensory pathways.

This study is designed to determine if adding daily weighted braces on the unaffected ankle may benefit to patient who have returned home compare to a placebo intervention (ankle brace without weight).

Our proposal quantitatively analyzes gait dynamics of hemiplegic individuals in response to the Function Electrical Stimulation (FES) intervention and identifies the responders to the intervention. This study will improve our knowledge of FES intervention and help clinicians strategize the FES interventions more effectively based on the responders' gait characteristics, thus supporting the NINDS' fundamental goal of translating basic and clinical discoveries into better ways to prevent and treat neurological disorders.

The fundamental goals of early rehabilitation for patients with stroke are: optimizing motor function within each patient's prognostic potential, preventing the development of secondary conditions that impact life-long health, and promoting patient's participation in their lives. In addition to employ clinical measures after treatment, usual outcome measures employed in the intervention studies included movement kinematics (spatio-temporal characteristics of movements). Recent reports have suggested repetitive transcranial magnetic stimulation (rTMS) and BoNTA (BoNTA) improved motor function in patients with stroke. A novel rTMS paradigm, theta burst stimulation (TBS), including intermittent TBS (iTBS) and continuous TBS (cTBS), that modulates human cortical excitability differently. However, there is lack of literatures in verifying the treatment effect by the integration of clinical and kinematic analysis. Until now, there are no conclusive results regarding optimal rTMS protocol, such as stimulating pattern and for patients with stroke. Additionally, few studies investigate the possible clinical characteristics of patients with stroke that may influence the effects of various treatment protocols proposed in this project.

The purpose of this study is: To augment the MAHI Exo-II, a physical human exoskeleton, with a non-invasive brain machine interface (BMI) to actively include patient in the control loop and thereby making the therapy 'active'. To determine appropriate robotic (kinematic data acquired through sensors on robotic device ) and electrophysiological ( electroencephalography- EEG based) measures of arm motor impairment and recovery after stroke. To demonstrate that the BMI controlled MAHI Exo-II robotic arm training is feasible and effective in improving arm motor functions in sub-acute and chronic stroke population.

Armodafinil is an FDA approved medication with wakefulness-promoting properties. It is a relatively safe agent with interesting neurochemical effects on the catecholamine system, producing an improvement in cognitive function, particularly working memory in humans. When combined with intensive task-related training, armodafinil may accelerate motor recovery in chronic stroke patients. The primary aim of this study is to determine whether administration of armodafinil during subacute post-stroke rehabilitation will augment cortical plasticity and enhance motor recovery. The primary hypothesis suggests that cortical plasticity will be enhanced by armodafinil and, therefore, will induce an improvement in motor function and better performances on measures of motor control.

An exploratory clinical study on a Variable Speed and Sensing Treadmill system(VASST) for hemiparetic gait rehabilitation after stroke. Building upon the positive results of VASST I conducted in 2012, VASST II will be an open label pilot trial of 11 subjects screened for eligibility by TTSH medical and rehabilitation team Study hypotheses : Training on VASST may result in a gain of +40% - 50% for distance walked and +10-20% of gait speed compared to baseline and response rate of 85% and serious adverse event rate of <10%.

The purpose of this controlled, randomized intervention is to investigate whether a fat-based (ketogenic) diet given for a week has a positive effect on blood sugar, mortality and function in patients hospitalized with acute stroke compared to the effect of a usual diet. The study hypothesis is that a ketogenic diet and reduced availability of glucose to the brain cells will reduce the volume of neuronal damage in the brain and improve function. The intervention will take place at the neurological units of Glostrup and Bispebjerg Hospital in Denmark.

The aim of this study is to evaluate the safety of Ginkgolides Meglumine Injection in the treatment of ischemic stroke with Syndrome of Intermingled Phlegm and Blood Stasis.
