Active clinical trials for "Stroke"

This pilot study examined the effect of task-oriented mobility training in three persons chronic post-stroke using a novel, wearable, mobile intention-based robotic orthosis (Tibion Bionic Leg).

This is a sub-project of a larger NIDRR Grant. One promising form of robotic training that leverages the power of neuro-plasticity is error augmentation. In this paradigm the computer singles out and magnifies a stroke survivor's movement errors from a desired trajectory, thus forcing the subjects to strengthen their control. Using the VRROOM, a state-of-the-art system which uses haptics (robotic forces) and graphics (visual display) interfaces, a subject's desired trajectory can be determined and the movement errors can be amplified in real-time with dramatic results. This project evaluates a practical approach of error augmentation, using therapist-driven trajectories. The investigators intend to determine clinical efficacy of several types of therapist-assisted error augmentation on retraining the nervous system in functional activities. The investigators will test two experimental treatments in a crossover design. The investigators hypothesize that combined haptic and visual error augmentation will lead to the best functional recovery.

The propose of this study is to evaluate the feasibility and the clinical efficiency of feedback-controlled robotics-assisted treadmill exercise (RATE) technology for cardiovascular rehabilitation early after stroke. The investigators hypothesize that feedback-controlled RATE might be suitable and effective to improve cardiovascular fitness and functional carryover in non-ambulatory individuals with sub-acute stroke.

The thermal stimulation have been proven effective in upper extremity of stroke patients. Therefore, this study explored the efficacy of thermal stimulation in lower extremity of stroke patients.

Stroke is a leading cause of morbidity in the United States but identification of treatment strategies to improve outcome is limited by the incomplete understanding of the mechanisms of recovery. Motor cortex (M1) reorganization plays a major-role in the recovery of motor deficits post-stroke; hence the importance for further development of rehabilitative strategies that utilize this potential for recovery. In Specific Aim 1, investigators will determine if repeated exposure to training combined with Hebbian-type M1 stimulation enhances functional M1 reorganization in lesioned M1 of stroke patients. In Specific Aim 2, investigators will determine if repeated exposure to training combined with Hebbian-type M1 stimulation enhances structural cortical reorganization in lesioned M1 of stroke patients and to explore whether these structural changes are related to the training induced functional cortical reorganization. The overall goal of this project is to determine the effect of Hebbian- type stimulation on both, functional and structural brain reorganization, thereby obtaining indirect evidence for the neuronal substrate underlying training related improvement and maintenance of motor function in stroke patients. This knowledge may have a substantial positive impact on treatment for stroke patients that may significantly improve recovery and could move the field of neuro-rehabilitation forward.

The objective of this study is to collect data on the use of the SOLITAIR FR device for treatment of acute ischemic stroke with large artery occlusion i.e. to investigate, whether the application of SOLITAIR is a safe and feasible method for interventional recanalization of large vessels with favorable patient outcome in acute stroke therapy.

This is a randomized, assessor-blind, placebo controlled study in post stroke depression patients. Subjects receiving antidepressant drug would be assigned to either active or placebo scalp electro-acupuncture treatment, on the hypothesis that acupuncture intervention combined with antidepressants could produce greater therapeutic effects than antidepressants alone.

The purpose of this study is to develop and assess the effectiveness of robot-assisted movement therapy in enhancing hand motor function in subjects with chronic hemiparetic stroke, and to identify predictors of treatment response.

The purpose is to demonstrate the safety of intravenous tissue plasminogen activator (IV t-PA) in ischemic stroke patients who present to the emergency department (ED) after awakening with the symptoms of suspected ischemic stroke.

The purpose of this study is to determine whether injections of Botulinum toxin type A into muscles of the upper limb are effective in treating spasticity in patients after stroke.
