NCT ID: NCT03689491 Active, not recruiting - Stroke Clinical Trials

The Combining rTMS With Visual Feedback Training for Patients With Stroke

Start date: February 13, 2015
Phase: N/A
Study type: Interventional

After stroke, patients often experience motor deficits that interrupt normal lower extremity movement and gait function. Recent developments in neuroimaging have focus on the reasons why some patients recover well while some do poorly. However, there is still no consensus on the exact mechanisms involved in regaining the functions after rehabilitation. Application of repetitive transcranial magnetic stimulation (rTMS) to facilitate neural plasticity during stroke treatment has recently gained considerable attention. The possible mechanism through which rTMS acts is based on the interhemispheric competition (IHC) model, which explains that patients with stroke experience alterations in cortical excitability and exhibit abnormally high interhemispheric inhibition from the unaffected hemisphere to the affected hemisphere. The visual feedback training can improve postural control and enhance motor performance. Several rTMS studies have evaluated the lower extremity dysfunction following stroke, but few studies have explored the efficacy of applying rTMS on the lower extremities. We expect the study can help us to further exploration of the change of clinical function and cortical excitability following rTMS and visual feedback training in subjects with stroke. In addition, the results of this project will be provided for further rehabilitation programs in people with stroke.

NCT ID: NCT03689387 Completed - Clinical trials for Cerebral Vascular Disorder

Evaluation of Physical Activity Practice (AP) After Cerebral Vascular Stroke (Stroke)

Start date: October 23, 2017
Study type: Observational

Physical activity is defined by any movement produced by the skeletal muscles responsible for an increase in energy expenditure. The Stroke Council of the American Heart Association (AHA) recommends, in prevention after the occurrence of a first stroke, the practice of moderate to intense physical activity for 40 minutes a day, three to four times a week (Lackland et al., 2014). The World Health Organization (WHO) also recommends the practice of at least 150 minutes of moderate-intensity endurance activity or at least 75 minutes of endurance activity of sustained intensity per week, adapted to the possibilities of the patient (World Health Organization 2010). Unfortunately, the majority of stroke patients have activity below recommendation (Rand et al., 2009). The main hypothesis of this work is that the amount of AP, measured by self-questionnaire, is insufficient, and below current recommendations in patients with stroke, after return home. Given the multiple physical, psychological, social, and economic benefits of PA practice, it is also important to identify the habits and challenges that patients experience with PA, so that they can be better informed. advise and guide them to reach AP stroke recommendations.

The Effects of Gait Rehabilitation After Stroke by Treadmill-based Robotics Versus Traditional Gait Training

Start date: June 20, 2018
Study type: Observational [Patient Registry]

This multi-site randomized controlled trial aims to investigate the effectiveness (increase of the walking speed in the 10 Meter Walk Test - 10MWT) of the robotic treatment with exoskeleton or end-effector system compared to the conventional rehabilitative treatment for the gait recovery after stroke, and to compare the possible different efficacy of end-effector and exoskeleton systems in the various post stroke disability frameworks. All the eligible subjects admitted to rehabilitation centers, both in subacute or chronic phase will be recorded. The experimental group will follow a set of robotic gait training by on the treadmill based robotic systems which does not provide the over ground gait training (Lokomat Pro - Hocoma AG, Volketswil, Switzerland; G-EO System - Reha technologies, Italy). While, the controll group will follow a traditional gait training composed of all those exercises which promote the recovery of walking ability (please, see the interventions details).

NCT ID: NCT03686280 Not yet recruiting - Stroke Sequelae Clinical Trials

Resume Walking by an Interactive Mobile Robot of Rehabilitation After Vascular Stroke (Cerebral Vascular Stroke)

Start date: December 2018
Phase: N/A
Study type: Interventional

The recovery of a balance and gait is a primary objective for geriatric, neurological or orthopedic rehabilitation. Since the 80s, many walking robots were proposed. Despite encouraging results, the use of robotic equipment for gait training remains limited, even if they meet a strong social demand. The reasons for this situation are economic, but also related to the non consideration of the context of utilization . This project aimed at developping a mobile and interactive robot, dedicated to the rehabilitation of balance and gait at an early stage. It was intended for patients with impaired walking vascular neurological, traumatic or associated with chronic neurological disease. The aim of the study is to study the effectiveness of the prototype (interactive walking mobile robot).

NCT ID: NCT03686163 Recruiting - Clinical trials for Acute Ischemic Stroke

Effects of Intranasal Nerve Growth Factor for Acute Ischemic Stroke

Start date: January 2016
Phase: Phase 4
Study type: Interventional

Stroke remains one of the leading causes of death and adult disability worldwide. Yet, currently, the only accepted treatment for acute ischemic stroke(AIS) is recanalization of occluded arteries. Thrombolysis with tissue plasminogen activator, limited by its narrow therapeutic time window and the concern of hemorrhagic complication, is still uncommon in use. The other approach is to try to impede the ischemic cascade by targeting various components of the cascade that are deemed to be of importance, namely, a neuroprotection strategy. Nerve growth factor (NGF) plays extensive roles in preventing ischemic injury. Besides that, it is also involved in neurogenesis of the central nervous system (CNS). In addition, the levels of NGF protein and messenger RNA significantly decreased in the CNS at the first few hours and returned to normal levels several days later after middle cerebral artery occlusion (MCAO) in animal models. These observed results suggested that NGF was demanded in ischemic brain injury, but endogenous NGF is insufficient for the requirement and delivering exogenous ones will be blocked in entering into the CNS by the blood-brain barrier (BBB). Intracerebroventricular or intracerebral injection of NGF or grafting of NGF-producing cells may be less practicable due to invasiveness and safety concerns. Intranasal (IN) administration is a noninvasive and acceptable delivery strategy for drugs bypassing BBB and can deliver NGF to the CNS, which has been proved to show neuroprotective effects on brain injury. The effects of intranasal NGF in human ischemic stroke is still controversial that need further evaluation.

NCT ID: NCT03685006 Recruiting - Inflammation Clinical Trials

Atherosclerosis and Acute Ischemic Stroke Study

Start date: January 1, 2009
Study type: Observational [Patient Registry]

A significant proportion of strokes are thromboembolic in nature, arising from atherosclerotic plaque at the carotid bifurcation. It is now wellknown that inflammation plays a key role in atherogenesis and plaque destabilization. However the identification and characterization of the different inflammatory factors, as well as their relative importance, have not been clarified. This main aim of this study is to identify new risk markers for atherosclerosis and to characterize more precise methods for detection of the unstable carotid plaque with increased stroke-risk.

Acoustic Cueing During Slow-wave Sleep as a Measure to Improve Motor Rehabilitation Outcome in Patients With Ischemic Stroke

Start date: November 1, 2017
Phase: N/A
Study type: Interventional

This project aims at gaining insight into the role of sleep in motor learning and the first to apply sleep related learning methods in a rehabilitative setting. The primary objective is to investigate whether there is an effect of acoustic cueing during slow wave sleep on a specific motor task. The second objective is to investigate whether this effect can also be transferred to generalized motor rehabilitation outcome. Patients with an impairment of the arm function are randomized to either receiving the intervention ("cueing group") or to the control group. The patients are all listening to a melody during motor training but only the patients of the cueing group are also exposed to the melody during subsequent slow wave sleep. Performance gain is measured using an instrumented arm orthosis which is used for functional arm therapy over the sudy period of 5 consecutive days as well as during standard clinical assessments.
