Active clinical trials for "Stroke"

Stroke creats dependancy of patients due to various associated impairments. The use of low-cost technologies for neurological rehabilitation may be beneficial for the treatment of these patients.

Current protocols for therapy on a rehabilitation unit call for intensive rehabilitation composed of high intensity, long duration therapy. Evidence from brain healing and animal research, along with motor learning principles suggest that a treatment program composed of short duration therapy sessions distributed throughout the day may provide better rehabilitation outcomes for stroke patients. Such a program can be implemented using constraint-induced therapy in which the Veteran is provided with opportunities to use the affected limb while participating in a video game and completing complementary tasks in therapy. Additionally, rehabilitation outcomes may improve if Veterans are provided with regular opportunities to participate in gaming therapy at home after discharge from the hospital rather than having to travel to a clinic or receive limited or no follow-up in rural areas. This project will develop a therapeutic model that promotes use of the impaired arm and hand. Researchers often call this type of therapy "constraint induced therapy". In this study, participants focus on using the impaired limb rather than the unaffected limb. A small group of patients will participate in a question and answer session about preferences for activities which make up transfer tasks. Up to twenty-four (24) Veterans inpatient with hemiparesis due to stroke in the brain will be recruited from the Minneapolis VA Health Care System. Study participants will only be able to play the game using the impaired limb. Participants may also receive automated reminders to use the impaired arm throughout the day. Gaming will occur in patient room and during occupational therapy. Participants will have the option of being discharged with the gaming system for continued gameplay. Outcome measures will include motor function tests that evaluate upper extremity function.

The purpose of this study is to find alternative treatments for patient's suffering from depression after having a stroke.This study aims to show that accelerated rTMS is a safe, effective,and convenient treatment for patient's suffering from post-stroke depression in the acute to subacute phase. This will be an open label trial and thus all participants will receive the active rTMS intervention.

The aim of this study is to verify the effectiveness of tDCS combined with foot drop stimulation (FDS) on gait rehabilitation of post-stroke subjects with mild and moderate compromise.

This research will study the effects of a rehabilitation program assisted by a powered lower extremity exoskeleton in patients after stroke. It will compare clinical and biomechanical features of patients at baseline and after intervention. Additionally, it will also examine the use of a brain-computer-interface (BCI) to command movements on the powered lower limb exoskeleton. The findings will be used to improve understanding human-robot interaction, to improve the design of the robotic devices and to improve rehabilitation services.

To explore the role of sonoelastography with shear wave velocity to assess poststroke spasticity of affected arm and forearm muscles in patients with stroke. To investigate the effects of Kinesiotaping applications on motor recovery, functional performance, and spasticity of affected upper extremity in patients with subacute stroke.

Stroke occurs as a result of blood vessels of the brain becoming blocked or bleeding which in turn can result in loss of function in the limbs. Rehabilitation of patients following stroke includes repetitive, task based exercises to help regain normal limb function. Developments in stroke rehabilitation have resulted in more and more therapeutic options being available for inclusion in the treatment plan of stroke patients. The benefits of computerised task based arm and hand rehabilitation exercises in stroke rehabilitation are well known. Computer based rehabilitation supports the stroke patient in performing high intensity, multiple repetition exercises and in doing so encourages the regeneration of brain cells. In addition, it is believed that the stimulating environment provided by computerised exercise programs encourages the ability to problem solve and perform tasks. However, the effects of such computer based treatments on cognition have rarely been studied. In Turkey to date there are no community based, task specific computerised exercise programmes available to stroke sufferers. Such systems may provide inpatient and community based stroke sufferers with a practical and economical therapeutic option as a part of stroke rehabilitation. Moreover, this may provide the patient with a mode of ongoing, long term therapeutic exercise and maintenance of skills acquired in the hospital rehabilitation period shortly after stroke. The aim of this study was to investigate the benefits of computer based, task specific exercises when compared to conventional rehabilitation alone on arm and hand function, quality of life and cognition in stroke patients.

Stroke is the leading cause of disability in adults in the United States. Despite advances in hyperacute stroke care, advancements in stroke rehabilitation are lagging. We have previously shown that a non-invasive, cost-effective, easy to perform intervention, called ischemic conditioning (IC), can improve paretic leg strength, reduce muscle fatigue, and increase walking speed in chronic stroke survivors (>1 year post-stroke). The IC procedure makes the paretic leg transiently ischemic (5 minutes) using a cuff inflated to 225 mmHg, and repeats the occlusion 5 times with 5 minute periods of rest between cycles (45 total minutes). It is well accepted that the response to IC is complex and involves local, humoral and neural factors. The mechanism by which IC can confer motor benefit in stroke survivors is unknown. The aim of this study is to examine if IC can increase sympathetic nervous system (SNS) activity, which would promote an increased cardiovascular response to exercise and increased muscle strength. We hypothesize that plasma epinephrine and norepinephrine levels will increase more during a cold pressor test (a well-tolerated test to induce a sympathetic response) in chronic stroke survivors who undergo a single session of IC vs. IC-Sham. To accomplish the goals of this study, 15 chronic stroke survivors will each make two visits to the adult translational research unit at Medical College of Wisconsin (MCW) to have either IC or IC-Sham performed on their paretic leg in a counterbalanced order. Venous blood will be drawn before and after the IC or IC-Sham procedure and after a two-minute cold pressor test where the study participants submerge their hand into a bucket of ice water. This will cause an increased sympathetic response, which will be assessed by measuring blood pressure and the relative increase in the levels of circulating catecholamines (epinephrine and norepinephrine, assessed by high performance liquid chromatography).

The objective of this study is to determine the optimal training intensity and the minimum training duration needed to maximize immediate improvements in walking capacity in chronic stroke. A single-blind, phase II, 3-site randomized controlled trial has been planned. Fifty persons >6 months post stroke will randomize to either moderate-intensity aerobic locomotor training or high-intensity interval locomotor training; each for 45 minutes, 3x/week for up to 36 total sessions over approximately 12 weeks. Clinical measures of walking function, aerobic fitness, daily walking activity and quality of life will be assessed at baseline (PRE) and after 4, 8 and 12 weeks of training (POST-4WK, POST-8WK, POST-12WK).
