Active clinical trials for "Stroke"

The purpose of this study is to determine whether bladder catheterization can be safely avoided in patients admitted to the hospital with stroke using a nursing protocol, and whether this decreases the incidence of urinary tract infections. The investigators hypothesize that the protocol will be tolerated by nurses and patients, and that patients without bladder catheters will have fewer urinary tract infections and better outcomes.

The purpose of CLOTBUST-HF is to determine the safety of a novel, external Hands-Free transcranial Doppler (TCD) ultrasound system in healthy volunteers and ischemic stroke patients. If found to be safe, the widespread use of operator-independent, ultrasound-enhanced thrombolysis will allow the planning for a large Phase III efficacy trial.

The initiative to the study is based on the fact that various forms of enriched environments and multimodal stimulation are found to have positive influences on motivation and psychosocial well-being and have been shown to facilitate multiple processes in the brain leading to structural regeneration and functional recovery. Since there is a lack of rehabilitation programs that encompass all dimensions of a stroke survivor's life researchers agree upon the need for a rehabilitation program that addresses both the social and physical needs of the patients. The aim with the project is to investigate whether it is possible to improve the life situation among patients with a history of stroke through a rhythm and music method and therapeutic riding. To get insights in the underlying mechanisms our research also focuses on relevant physiological, neurobiological and psychosocial mechanisms induced by the interventions. The hypothesis is that both treatment methods will mainly enhance participants' degree of participation. The study is a randomized controlled trial where about 123 participants (50-75 years old) who had their stroke incident 1 - 5 years ago will be consecutively included and randomly allocated to the following three groups: a) Ronnie Gardiner Rhythm Music Method (RGRM) b) therapeutic riding c) a control group receiving RGRM after 9 months. Treatment proceeds during 12 weeks and evaluation takes place pre- and post intervention, and 12 and 24 weeks after the treatment is finalized. The evaluation consists of a thorough neuropsychological assessment, a physiotherapeutic assessment, sampling of blood and questionnaires covering mental, psychosocial, physical and psychological well-being. Interviews are also conducted in order to map the participants' experiences from the two treatment programs. Specially designed interviews are also planned to be carried through with participants having aphasia. So far, there is only empirical support suggesting that RGRM has positive effects for individuals with a history of stroke making it significant to carry out research with the aim to contribute to strengthening the evidence of the method. A positive outcome would increase the scientific basis for this alternative treatment thus facilitating further research and implementation in everyday clinical practice.

More than half of individuals post-stroke have residual movement disabilities, including reduced mobility, balance, and increased risk of falling. There is a need for innovative, long-term and economically-feasible interventions for those with chronic stroke. Recently, a focus has been placed on the use of virtual reality and interactive gaming as a low cost and effective manner of treating movement disorders. Yet few studies have investigated interactive gaming platforms effect on balance following stroke. The proposed study is a randomized, single-blind, control group cross-over study for individuals with chronic stroke designed to examine an innovative therapeutic approach by investigating the effects of commercially-available gaming systems on balance, mobility and fear of falling in a sample of individuals with chronic motor deficits following stroke.

The primary aim of this study is to investigate the effectiveness of the use of a robotic hand therapy device in the home environment. We hypothesize that the therapy group will improve hand function more than a customary and usual care group.

The primary purpose of this study is to determine the effects of reinforcement of walking speed on recovery of walking speed over the course of inpatient rehabilitation for people after stroke. The study will also examine the relationship between short distance walking speed and walking distance over a fixed time.

To investigate the safety and efficacy of MLC601 (NeuroAideTM) as a Traditional Chinese Medicine on motor recovery after ischemic stroke.

Low-frequency repetitive transcranial magnetic stimulation (rTMS) of the unaffected hemisphere (UH) transiently improves motor function in patients in the chronic phase after stroke. The goal of this study is to investigate effects on motor recovery of low-frequency rTMS of the UH, administered in the subacute phase after stroke.

Impaired hand function is one of the most frequently persisting consequences of stroke. The purpose of this study is to compare two different treatments -- Contralataterally Controlled Functional Electrical Stimulation (CCFES) and Cyclic Neuromuscular Electrical Stimulation (cNMES) -- for improved recovery of hand function after stroke.

Paralysis following stroke stems not only from the loss of neurons killed by the stroke but also from the loss of neurons lying dormant in the stroke hemisphere. One of the reasons viable neurons become dormant (down-regulated) is because of excessive interhemispheric inhibition imposed on them from the nonstroke hemisphere. The challenge in neurorehabilitation is to restore excitability and voluntary control of these down-regulated neurons in the stroke hemisphere. Suppression of the source of this excessive interhemispheric inhibition can be achieved with the noninvasive method called repetitive transcranial magnetic stimulation (rTMS). It has been shown in healthy subjects that the known depressant effects of low-frequency rTMS can be increased and prolonged by preceding it with 6-Hz priming stimulation. In a recent safety study, we showed that one treatment of 6-Hz primed low-frequency rTMS applied to the nonstroke hemisphere is safe. It is now important to evaluate a series of these treatments and whether their efficacy can be enhanced by combining the rTMS with motor learning training. The specific aims of this study are to determine the efficacy, mechanism, and safety of a series of 5 treatments of 6-Hz primed low-frequency rTMS applied to nonstroke hemisphere and combined with motor learning training to promote recovery of the paretic hand. Forty subjects with stroke will be randomly assigned to one of four treatment groups. The rTMS/only group will receive 20 min. of rTMS per day. The Track/only group will receive 20 min. of finger tracking training per day. The rTMS/combined group will receive alternating days of the rTMS and Track treatments. The rTMS/sham group will receive 20 min. of rTMS using a sham electrode each day. The hypotheses are: 1) the rTMS/combined group will show the greatest improvements in hand function, 2) the rTMS/combined group will show the greatest improvements in cortical excitability using paired-pulse TMS testing and in brain reorganization using fMRI, and 3) the rTMS treatment will be safe. The proposed research is important because it addresses the greatest cause of long-term disability in society, hemiparesis following stroke, and it is innovative because it applies a technique never used before, 6-Hz primed low-frequency rTMS combined with motor learning training. The potential impact of this research is a radical change to rehabilitation that accomplishes a higher quality of life in stroke.
