Active clinical trials for "Stroke"

The long-term objective of this research is to develop an efficacious training paradigm to enhance stroke survivors' defense mechanisms against falls and possibly reduce healthcare cost. The Centers for Disease Control and Prevention estimates the direct medical cost for fall related injuries to be $34 billion annually. Forty percent to 70% of community-dwelling stroke survivors experience detrimental falls each year and tend to have 1.5 to 4 times higher risk of hip fracture than their healthy counterparts; with only less than 40% of those individuals regaining independent mobility. Falls, thus not only affect activities of daily living but also reduce mobility, increase risk of second stroke and mortality. Despite potential financial and functional implications of falls in this population, health-care personnel are limited in their ability to develop and validate interventions to reduce fall-risk for them. Further emphasis is placed on locomotor training with focus on enhancing paretic limb function. The project design consists of a randomized controlled trial to examine the ability of chronic stroke survivors to acquire, generalize and retain adaptations to slip-perturbation training for not only mitigating fall risk but also improving walking function. It also explores translation of this paradigm to the sub-acute population. The paradigm is novel in that it targets contributions of the paretic vs. non-paretic limbs on fall-risk through a bilateral training paradigm that involves training the non-paretic side first and then paretic to facilitate acquisition of fall-prevention skills on the paretic side, which may otherwise take longer to acquire training effects. The longer-term benefits of such perturbation training, targeting both limbs for reducing falls will be assessed not only in the laboratory but also in real life via wearable sensors, along with improved community walking function. The hypothesis of this study if supported by the results will provide an evidence-supported training protocol to reduce the fall-risk not only in people living with hemiparetic stroke but also among survivors of other acquired unilateral cortical lesions.

This clinical trial is a clinical trial for the evaluation of the safety and efficacy of umbilical cord blood (UCB) therapy, UCB and erythropoietin (EPO) combination therapy in adult stroke patients.

The purpose of the study is to examine the added effect of NeuroMuscular Electric Stimulation (NMES) in addition to exercise therapy in the acute phase of ischemic stroke. This randomized controlled trial includes 50 patients allocated to either control or intervention. The inclusion, test, training and re-test will be provided during the first 14 days after ictus, starting day 1 or 2 after ictus and a follow-up at day 90. The exercise training with external NMES is done with the patient every weekday for 12 minutes.

This is a non-blinded randomized study that will investigate whether the use of a novel, non-invasive perfusion enhancement system (The Guardian System) impacts motor recovery and hospital length of stay in acute ischemic stroke patients.

Despite numerous kinds of evidence on functional health and CNS protection of intermittent fasting after injuries were found in many brain-, and spinal cord-damaged animal models, there has yet to be any clinical study of intermittent fasting after acute ischemic cerebral infarction. The aim of this study is to evaluate the neurological, functional and clinical efficacy of intermittent fasting in patients after acute ischemic stroke.

Post-stroke depression (PSD) is one of the most common complications after stroke, with a high prevalence. PSD can affect prognosis and rehabilitation of stroke, increase risks of mortality and suicide, and escalate the economic burden on individuals and society. Studies have shown that transcranial alternating current stimulation (tACS) can also be used to treat depression, insomnia and anxiety. So far, this stimulator has been approved by FDA. However, there have not been any reports on the use of tACS in the treatment of depression and PSD in China. In this trial, the efficacy and safety of the tACS will be assessed with the rigor methodology manner.

Stroke is the second leading cause of death and disability in France: more than half of stroke survivors have a disabling motor deficit, affecting mainly the upper limb. A lack of hand control makes everyday tasks more difficult and reduces the quality of life. The investigators lack approaches to specifically rehabilitate the hand after stroke. Recently, a new tool has been developed to measure manual dexterity (the Finger Force Manipulandum or FFM). This tool, which records the forces applied by the fingers on pistons, allows to measure more finely the key components of manual dexterity during visuomotor tasks. The tool measures the ability to control and release the force applied by the fingers, to perform sequences, to track and maintain a frequency of tapping (temporality of movement) with the fingers, and to use the fingers independently one another.

A lot of studies prove that rehabilitation with the use of modern devices accelerates the recovery of function in patients after stroke. Repeated correct movement patterns affect the central nervous system and stimulating its plasticity. Despite the fact that so many studies confirm the validity of therapy using robots, it is still difficult to assess to what extent its use improves the effectiveness of traditional therapy. In these studies, we want to objectively assess the effectiveness of the Luna device using EMG biofeedback.

This study evaluates the effectiveness of stochastic resonance electric stimulation on neuromuscular control and proprioception in healthy and individuals with stroke.
