Filter by:This study evaluates the effectiveness of Guttmann NeuroPersonalTrainer (GNPT), a tele-rehabilitation platform developed as a tool for the cognitive rehabilitation of chronic stroke patients. All patients will receive this treatment but in different order: half will receive GNPT and the other half will receive sham cognitive training; after a washout period of three months, crossover will occur and participants from the GNPT condition will receive sham cognitive training, while participants originally from the control intervention will receive GNPT.
The purpose of this study is to compare the clinometric (psychometric) properties of the SCALE and FMA-LE assessments in adults after stroke. A second purpose is to determine how well each measure predicts walking speed using the 10 meter walk test.
The aim of this study is to investigate the effects of high-frequency short duration tablet-based speech and language therapy (teleSLT) mixed with cognitive training (teleCT) in chronic stroke patients. Recent studies suggest that chronic stroke patients benefit from SLT with high frequency and that cognitive abilities can play a role in sentence comprehension and production by individuals with aphasia. To investigate the effects of the distribution of training time for teleSLT and teleCT the investigators use two combinations. In the experimental group 80% of the training time will be devoted to teleSLT and 20% to teleCT whereas in the control group 20% of the training time will be devoted to teleSLT and 80% to teleCT. Both groups receive the same total amount and frequency of intervention but with different distributions. At three time points (pre-, post-test and 8 week follow-up) the patients' word finding ability is measured.
Robotic rehabilitation is promising to promote function in stroke patients. The assist as needed training paradigm has shown to stimulate neuroplasticity but often cannot be used because stroke patients are too impaired to actively control the robot against gravity. Aim of this study is to present a novel robotic approach based on fully assisted functional movements and to examine the effect of the intervention in terms of motor function improvement in subjects with chronic stroke in the short term and at 6-month follow up. A preliminary evaluation of the effectiveness of the intervention in improving activity and participation in the short term is also performed. Further, the study aims to verify whether some instrumental measures (using kinematics, EMG and EEG) may help gain insight into the mechanisms leading to improved motor ability following the robotic intervention and can be used to predict functional recovery.
This study aims to explore if the LSVT BIG® - a motor learning based treatment program designed for rehabilitation of people with Parkinson's disease could be beneficial for chronic stroke rehabilitation. A single-case experimental design with two adult participants, will be monitored for performance on self-selected goals before, during and after participating in the treatment program.
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.
The present study aims at investigating (i) the feasibility in chronic stroke of using a dedicated virtual reality (VR) based system that embeds real-time 3D motion capture and embodied visual feedback to deliver functional exercises designed for training of impaired upper limb motor skills, (ii) whether chronic stroke survivors improve in functional outcomes in the upper limb when exposed to intensive VR-based therapy, and (iii) safety and tolerance to such a technology. The investigators hypothesize that intensive VR-based rehabilitation may lead to high rehabilitation doses and functional improvement in chronic stroke.
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.
The purpose of this study was to compare the treatment effects of home-based or clinic-based bilateral training with and without mirror feedback programon on physiological markers, sensorimotor, cognition, daily functions, and participation among patients with chronic stroke.
The investigators will conduct a randomized controlled trial study to provide preliminary evidence of efficacy of exercise training or a complex mental and social activities program for improving cognitive function in older adults with chronic stroke, compared with a stretch and relaxation program.
