This study seeks to explore the efficacy of several control mechanisms for the device and the impact of a device training program on its utility as a neuroprosthetic and training tool for upper limb recovery.
Assess the ability of the Visor System to detect hemispheric bioimpedance asymmetry
The aim of this study was to identify the assistance effect of Ankle Assist Robot v1 developed by Samsung Advanced Institute of Technology (Samsung Electronics Co, Ltd., Korea) by comparing 1. gait function during overground gait in three conditions (with robot-assist torque on/with robot-assist torque off/without robot) 2. the energy expenditure during treadmill gait in three conditions (with robot-assist torque on/with robot-assist torque off/without robot) 3. the result of Timed up and go test in two conditions (with robot-assist torque on/without robot)
About 50% of all stroke patients develop post-stroke depression (PSD). A meta-analysis has shown that rTMS treatment can reduce depressive symptoms in PSD patients. In addition to rTMS alone for the improvement of depression, the question arises as to whether a combination therapy of rTMS plus antidepressant medication can achieve a stronger or longer-term effect in PSD patients. Unfortunately, there are currently no trials of combination therapy with rTMS and drug therapy in PSD patients. Therefore, this study will investigate whether combination therapy of antidepressant and rTMS can provide additional relief of depressive symptoms compared to antidepressant and sham rTMS therapy. It is assumed that the additional active rTMS achieves a faster normalization of affect and drive than with a sham rTMS, so that the patients benefit from neurorehabilitation measures earlier and more sustainably.
Stroke is a leading cause of death and long-term disability worldwide and its incidence is on the rise. Importantly, loss of arm function occurs in up to 85% of stroke survivors, with a significant long-term impact on activities of daily living, leisure activities and work. The capacity for recovery following a stroke depends on several factors, including the extent of the initial neurological damage, spontaneous recovery and rehabilitation, with possible recovery even years after the stroke. Unfortunately, accessibility of much needed rehabilitation services poststroke often remains limited, both in terms of intensity and duration, as reported in a recent report on post-stroke rehabilitation services in Quebec. Recent evidence suggests that homebased telerehabilitation (TR) is a viable approach for upper limb training post-stroke when rehabilitation services are not available. Similarly, the Canadian Best Practice Recommendations for Stroke Care update for 2013 recommends home-based patient monitoring be used when frequent monitoring is needed and face-to-face visits are not available. Hence, the investigators have developed and propose to examine the use of the VirTele system for people who have suffered a stroke who are no longer receiving rehabilitation services The VirTele system allows upper limb rehabilitation using exergames with ongoing off-line monitoring combined with online monitoring and coaching based on the self-determination theory.
The purpose of this study is to compare conventional balance training to reactive training and to a novel, high intensity, harnessed training program. This study examines the impact of these interventions on fall risk and on a range of important aspects of balance including overall mobility, quality of life, and health. Participants will be 60-69 adults who had a stroke more than 6 months ago and who ambulate independently. Each participant will complete 14 sessions consisting of 4 (2 pre-, 2 post-) testing sessions and 10 intervention sessions. The pre and post testing will be the same and will consist of clinical and survey based balance and quality of life assessments and treadmill based perturbed gait testing. The pretest will be sessions 1 and 2 will be followed by 10 intervention sessions. There will be 3 treatment groups: a conventional balance training group (PT), a reactive slip training group (Slip), and a multidirectional harness group (MHG). Participants will be randomly assigned to a group following screening and consent. The conventional balance training group (PT) will receive 10 sessions of individualized standard of care physical therapy with the goal of improving balance and mobility. The only instructions to the PT are that the focus of the course of care should be on "balance and mobility" and that there should be 10 sessions. The reactive slip training group (Slip) will complete a standing slip session using the current protocol of scaling slip distance and force to each individual and modulating the slip intensity across the session based on subject responses. The remaining nine intervention sessions will consist of accompanied walking for up to 45 minutes. Participants will walk at a comfortable pace while accompanied by a researcher. The multidirectional harness group (MHG) will use a harness that allows movement in all directions, playing selected Kinect™ active video games with varied balance demands, on multiple balance training surfaces (e.g., rocker board, foam, slider platform). Participants will wear the fall-arresting harness for all game play. Motion data will be collected during Sessions 2, 6, and 10. For all groups, two-post-test sessions will follow the intervention sessions and will be the same as the two-pretest session. The final session will also include reviewing the participants' falls diaries and setting up procedures for contacting participants weekly or biweekly about falls.
With mechanical thrombectomy now representing standard of care for treatment of acute ischemic stroke secondary to large vessel occlusion, identifying adjunctive techniques that result in improved outcomes for patients with LVO has become an issue of increasing importance. A number of retrospective studies have demonstrated that flow arrest during the clot retrieval process results in less clot fragmentation, lower rates of distal emboli, higher revascularization rates and improved rates of good neurological outcome.
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 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 based on the presence of an Intracranial Carotid Artery (ICA) or Middle Cerebral Artery (MCA)-M1 occlusion 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
