Filter by:This is a single arm, multi-site, prospective hybrid implementation and feasibility trial. The primary purpose of this trial is to gather data on the facilitators and barriers to clinical implementation of MR-001 for patients with chronic stroke who experience walking impairments. Secondarily, the trial will evaluate the feasibility of MR-001 clinically impacting walking capacity, quality of life, mood, and cognition. The goal of this single arm, multi-site, prospective hybrid implementation and feasibility trial is to gather data on the facilitators and barriers to clinical implementation of MR-001 for patient with chronic stroke who experience walking impairments. The main questions it aims to answer are: 1. Enhance understanding of the potential clinical and operational needs and opportunities that may be associated with implementation of MR-001 in various treatment settings. 2. Assess the impact of MR-001 on walking capacity. 3. Assess the impact of MR-001 on quality of life and mood. 4. Assess the impact of MR-001 on cognition. All participants will be prescribed MR-001 and will be asked to walk with it for 30 minutes, 3 times weekly, for 8 weeks.
The purpose of this study is to assess the effect of rTMS and tDCS coupled with robotic therapy on upper extremity functional recovery
Few treatments are available for post-stroke rehabilitation. The current study aims to develop a novel, short-term, high-dose repetitive transcranial magnetic stimulation (rTMS) based intervention to improve post-stroke cognitive problems. This study will test the safety as well as changes in cognitive function and brain activation with the administration of an accelerated rTMS protocol in chronic stroke.
The primary objective of this study is to evaluate the efficacy for subjects with chronic stroke after GXNPC-1 injection.
Chronic stroke patients (> 6 months) with severe motor impairment of the upper extremity will be enrolled in this single-centre, randomized controlled clinical trial (RCT). All patients will take part in two blocks of high-intense motor training with concurrent neuromuscular stimulation of the paretic upper extremity. In a randomized, cross-over block design, patients will receive transcranial stimulation of either the ipsi- or contralesional hemisphere.
The purpose of this study is to find out what are the best settings for applying electrical nerve stimulation over the skin for the short-term improvement of hand dysfunction after a stroke. The ultimate goal is to some day design an effective long-term training program to help someone recovery their ability to use their hands and function independently at home and in society. In order to know how to apply electrical nerve stimulation to produce a good long-term effect on hand dysfunction, we first need to know how to make it work best in the short-term, and improve our understanding of for whom it works and how it works.We will use a commercially available transcutaneous electrical nerve stimulation (TENS) unit to gently apply electrical nerve stimulation over the skin of the affected arm. This is a portable, safe and easy to use device designed for patients to operate in their homes.
Clinical assessment of motor and sensory deficits is still today largely based on tests that do not permit any precise quantification. However, robotic technologies, coupled with neuroimaging techniques constitute new tools to assess sensorimotor functions that could allow to conceive neurorehabilitation protocols better adapted to the neurological impairment of each patient and to her/his specific recovery profile. The goal of this project is to contribute identifying the factors that determine functional recovery in stroke patients presenting upper-limb motor deficits. Here, we will focus our research on two factors that contribute in a complementary way to motor control: 1) the processing of proprioceptive informations, and 2) the processing of movement-execution errors. In this purpose, we will combine psychophysical methods that allow to precisely quantify sensorimotor deficits with functional and anatomical neuroimaging techniques. More specifically, we will exploit experimental protocols that have been developed in basic research, that use a robotic exoskeleton coupled with a virtual reality device, to precisely quantify motor and proprioceptive deficits in stroke patients. Then, we will link these behavioral data to electroencephalographic (EEG) signals recorded during a motor adaptation task, as well as to anatomical data, namely conventional magnetic resonance imaging (MRI) completed by diffusion tensor images (DTI) in order to achieve a finer description of the cerebral lesions. The present study will include two experimental parts, respectively centered on the proprioceptive deficits (Part 1) and the anomalies in the processing of movement-execution errors (Part 2). Proprioceptive deficits in stroke patients : We will test the hypothesis that, when present, deficits in kinaesthesia and troubles in unconscious proprioception contribute substantially to motor deficits in stroke patients ; with as a corollary hypothesis, that deficits in " proprioception for action " are more determinant than deficits in the conscious sense of position (classically tested in clinics). In this purpose, we will collect three sets of behavioral data, in chronic stroke patients and healthy control participants, respectively intended to assess a) motor deficits, b) troubles in conscious sense of position, and c) deficits in "proprioception for action". To better document the neuronatomical substrates of these different types of deficits. In this purpose, we will link the obtained behavioral data with the results of detailed analyses of the lesions of the tested stroke patients. Anomalies in the processing of movement-execution errors in stroke patients : We will assess movement-execution error processing in stroke patients, in order to test the idea that anomalies in error processing might contribute to motor deficits in stroke patients. In this purpose, we will record an electrophysiological correlate (ERP) of movement-error processing during a motor adaptation task. We will analyse the relation between the modulation of this ERP and motor performance. We will also examine the relation between these two sets of data (behavioral and electrophysiological) and the behavioral data collected during the first part of the study (Proprioceptive deficits). This will provide us with insight into the relationship between proprioceptive deficits and cinematic error processing. As in the first part of the study, we will link the observed electrophysiological and behavioral anomalies with the results of a detailed analysis of the anatomical lesions of the tested patients.
