Filter by:This study is a prospective, multi-center, open-label, end-point blinded, randomized, parallel positive control, non-inferiority clinical trial, with a purpose to evaluate the safety and efficacy of Hemo Jirui intracranial thrombus aspiration catheter system for endovascular treatment of acute ischemic stroke by comparison with stent retriever (Solitaire FR). The trial is anticipated to last from November 2018 to May 2019, with 204 subjects recruited from 15-20 clinical trial centers in China.
Balance is controlled through a complex process involving sensory, visual, vestibular and cerebral functioning which get affected by various neurological disorders such as in stroke. Different types of exercises are designed to target to cope up with the imbalance developed due to these neurological disorders. This study aimed to compare the efficacy of dual-task training using two different priority instructional sets in improving gait parameters such as self-selected velocity, fast speed, step length, and stride length in chronic stroke patients.
A new clothing robotic arm was developed for multi-joint coordinated upper limb rehabilitation after stroke. Patients after stroke will be recruited to evaluate the rehabilitation effectiveness of the device assisted upper limb rehabilitation. Both patients with chronic stroke and subacute stroke will be investigated.
This study is to investigate the combined effects of repetitive Transcranial Magnetic Stimulation (rTMS) and Augmented Reality (AR) intervention on cortical excitability, balance, gait, activity in individuals with stroke. Forty participants will be recruited in this study. They will be allocated to four group: rTMS and AR group (10), sham rTMS and AR group (10), AR group (10), and conventional physiotherapy group (10).
To study the feasibility and usefulness of multimodal MR compared to multimodal CT to select patients with acute ischemic stroke and favorable clinical outcome after mechanical thrombectomy. The specific objectives are to compare (1) the door-picture time and door-groin puncture time, (2) the rate of patients with acute stroke selected for endovascular treatment and (3) the safety and clinical response after thrombectomy between the two groups selected according to the imaging modality. Methodology: Single-center, randomized 1:1 and stratified by age and NIHSS study of consecutive patients with suspected acute ischemic stroke. Occlusion site, ischemic volume (core) and perfusion volume will be studied by an automated perfusion system (RAPID software) in both neuroimaging groups. Mechanical thrombectomy criteria will be basically based on the presence of a Large Vessel Occlusion (LVO) and a volume of core lower than 70cc in the Cerebral Blood Flow (CBF) or Diffusion Weighted Image (DWI) sequences. Modified Rankin scale at 90 days and the rate of intracranial hemorrhage and mortality will be considered as variables of response.
Currently, the guideline recommended re-perfusion such as intravenous thrombolysis and mechanical thrombectomy as the most effective treatment for acute ischemic stroke. However, the two methods are restricted by a strict time window, which greatly limits the number of the patients receiving treatment. The abundant studies have suggested that good collateral circulation can provide compensatory blood supply to save the ischemic penumbra and reduces the infarct volume, which improves the prognosis. How to improve collateral circulation in an efficient and safe way is a clinical challenge. Our recent experiment results of the animal and preliminary clinical experiments show that head-down position may significantly increase cerebral perfusion and improve neurological function. Clinically, head-down position is simple and easy to operate, and theoretically may increases brain perfusion and improve collateral circulation. A pilot randomized clinical trial is designed to investigate the effect of head-down position combined with routine rehabilitation in patients with ischemic stroke.The study is designed to explore the efficacy and safety of head-down position in patients with acute ischemic stroke
Building confidence and capabilities to transfer rehabilitative knowledge and skills into lifestyle-workable strategies for changing health behaviours among stroke survivors are important to optimise health outcomes and reduce risks of recurrent stroke. The aim of this project is to promote stroke survivors' health by building confidence and positive expectations of recovery outcomes, and enabling their engagement in stroke self-management behaviours.
The Virtual Reality Glove for Hand and Arm Rehabilitation (vREHAB) trial is a randomized, controlled, phase 3 trial aiming to evaluate the safety, usability, and efficacy of a virtual reality biofeedback system (Neofect RAPAEL Smart Glove) to promote recovery of distal arm and hand function in the acute and subacute period after stroke, as compared to standard of care therapy. The aims of the study is to demonstrate: 1. the effect of Smart Glove use on functional recovery, in addition to standard of care rehabilitation therapy. 2. the feasibility of increasing the dose of rehabilitation in acute stroke patients with the Smart Glove. 3. the effect of Smart Glove use on quality of life.
The aim of the study is to quantify elementary mechanisms of motivation, with innovative tools adapted to clinical settings, in healthy subjects, and in stroke patients, and to investigate their predictive value related to morbimortality, disability, and dependence. The secondary aim of the study is to investigate the neural substrates of motivational mechanisms, and to study the impact of lesions in the grey and the white matter, the influence of lesion site, and the consequences of disconnection in functional networks.
The current treatment based on evidence-based medicine for acute ischemic stroke mainly includes reperfusion (intravenous thrombolysis, mechanical thrombolysis), anti-platelet and stroke units. About 1/3 patients can obtain good prognosis through intravenous thrombolysis. Good prognosis can be gotten from about 50 percent of patients with big artery disease by mechanical embolization. However, only a small proportion of the population can be treated with restoration perfusion in the time window. The main purpose of antiplatelet therapy is to prevent the recurrence and progression of stroke, and stroke unit is a kind of management mode. How to improve the neurological function of patients has been a hot and difficult problem in clinical practice. A large number of basic and clinical studies have proved that remote ischemic conditioning (RIC) has protective effect on ischemic stroke. Hahn et al showed that RIC could play a neuroprotective role in cerebral ischemia-reperfusion injury in MCAO model. Other studies have also confirmed that preconditioning RIC has a neuroprotective effect on cerebral ischemia in animal models. One open label study by Hougaard et al shows that RIC can improve the NIHSS score in acute ischemic stroke patients. One recent study found that 300 consecutive days RIC therapy for the patients with symptomatic intracranial atherosclerotic stenosis significantly reduced the recurrence rate of stroke, improved the mRS score and recovered the blood flow in the lesion site. Furthermore, several studies have also shown that RIC can not only improve the neurological function of patients with cerebral infarction after intravenous thrombolysis and mechanical thrombolysis, but also protect the secondary brain injury after carotid stenting. These results suggest that RIC has a neuroprotective effect on ischemic stroke and deserves further study. Based on the above discussion, this study aims to explore the efficacy and safety of RIC in the treatment of acute moderate ischemic stroke.
