VARA (Virtual and Augmented Reality Applications in Rehabilitation): Motor Rehabilitation Protocol...
HemiparesisThe main goal of the study is to verify the efficacy of the GRAIL system in respect to the walking pattern improvement in a population of hemiparetic subjects. In particular, the specific goals will be: increase in walking symmetry and a better distribution among the time of stance and swing. Kinematics and Kinetics correction, with incentive of more corrected activation timing. Recruitment of the muscles most involved by the paresis, with the help of visual feedback. walking speed increase (but with the priority of the walking pattern) increase in the resistance Stregthening of the support reaction
Comparison of Thermo-plastic Versus Carbon Foot Ankle Orthosis to Improve Gait and Reduce Fatigue...
Hemiparesis;Poststroke/CVAGait1 moreApproximately 20% of stroke survivors have difficulties to dorsiflex the ankle and clear the ground during walking. This impairment, termed as "foot drop", is caused by an association of weak dorsiflexors and increased spasticity and stiffness of the plantar-flexors. As a consequence, walking performances are reduced and energy cost of walking is deteriorated. This may increase performance fatigability, as the locomotion will be realized at a higher percentage of the subjects' capacities. In order to overcome these issues, different treatments are proposed. One of the most conventional solutions are the use of ankle foot orthosis (AFO) and it is the most commonly prescribed device used to compensate for "foot drop". There is a very large choice of AFO on the market which can be proposed to patients with foot drop. The aim of this study is thus to assess the mechanical effects of using a manufactured carbon AFO in by comparison to a custom-made thermo-plastic AFO on walking capacity (distance and energy cost), fatigue and "foot drop" control throughout the gait phase in patients with hemiparetic stroke.
Effects of Hand MOtor Rehabilitation Using a sEMG-biofeedback
StrokeStroke3 moreStroke is the first cause of disability worldwide. The motor impairment of the hand is one of the most common sequelae in patients after stroke. Indeed, approximately 60% of patients with diagnosis of stroke suffers from hand sensorimotor impairment. In the last years, new approaches in neurorehabilitation field has been permitted to enhance hand motor recovery. Wearable devices permit to apply sensors to the patient's body for monitoring the kinematic and dynamic characteristics of patient's motion. Moreover, wearable sensors combined with electrodes detecting muscle activation (i.e. surface electromyography - sEMG) permit to provide biofeedback to the patient to improve motor recovery.
Hemiparetic Arm Robotic Mobilization With Non Invasive Electrical Stimulation
StrokeParesis1 moreThe two cerebral hemispheres find themselves in a state of balanced mutual inhibition. A stroke with involvement of motor function leads to a reduced excitability in affected hemisphere M1 and to an increased excitability of contralateral M1. Stroke therefore might impair interhemispheric balance, leading to a decreased inhibition of contralesional hemisphere by ipsilesional hemisphere and, in turn, to an increased inhibition of ipsilesional hemisphere by contralesional hemisphere. Permanence of healthy hemisphere hyperactivation in chronic phase after stroke is usually index of little functional recovery and is correlated with a greater ipsilateral structural damage. Robot-mediated physical therapy is an innovative rehabilitation technique that is effective in stroke patients. In this study, the investigators will add a non-invasive brain stimulation protocol with Transcranial stimulation with direct current (tDCS) to the robotic treatment in chronic stroke patients. tDCS is a non-invasive brain stimulation technique that is able to modulate cortical excitability. The hypothesis is that dual t-DCS (ipsilesional excitation and concomitant contralesional inhibition) could restore interhemispheric balance improving the benefits of robotic therapy with Armeo Power®.
Optimizing Transcranial Direct Current Stimulation for Motor Recovery From Hemiparesis
StrokeCerebrovascular AccidentThis study will compare the effectiveness of different polarities of transcranial direct current stimulation paired with intensive motor training in recovery of upper extremity function in individuals with severe post-stroke hemiparesis. The hypothesis is that more severely impaired individuals will derive greater benefit from anodal stimulation of the ipsilesional hemisphere or cathodal stimulation of the contralesional hemisphere than dual stimulation (anodal applied to the ipsilesional hemisphere and cathodal applied to the contralesional hemisphere.)
A Study to Evaluate the Safety, Efficacy, and Pharmacokinetics of ARGX-113 in Patients With Myasthenia...
Myasthenia GravisThis is a randomized, double-blind, placebo-controlled, multicenter Phase II study to evaluate the safety, efficacy, and pharmacokinetics of ARGX-113 for the treatment of autoimmune Myasthenia Gravis (MG) with generalized muscle weakness.
Constraint-induced Movement Therapy to Improve Gait and Mobility of People With Chronic Stroke
RehabilitationRecovery of Function2 moreThe purpose of this single-subject, concurrent mixed methods study is to investigate the relationship between the effect of the CIMT protocol on gait and mobility and participants' and caregivers' expectations and perceptions regarding the treatment. The goal of the quantitative strand is to assess changes in quality of movement and functional use of the paretic lower limb after the treatment and investigate the participants' expectations in regards the intervention using the Participant Opinion Survey (POS). The qualitative strand (participant interviews) will determine perspectives of caregiver and participant perspectives regarding protocol acceptability. Both quantitative and qualitative data will be collected and analyzed concurrently, through triangulation and complementarity rationales; both data will be equally prioritized.
Pilot Investigation of Stem Cells in Stroke Phase II Efficacy
Ischaemic StrokeCerebral Infarction2 moreThe primary aim of this Phase II trial is to determine whether it is sufficiently likely that CTX DP treatment at a dose level of 20 million cells improves the recovery in the use of the paretic arm in acute stroke patients to justify a subsequent larger prospectively controlled study. This study will evaluate the safety and efficacy of intracerebral CTX DP at a dose level of 20 million cells in patients with paresis of an arm following an ischaemic middle cerebral artery (MCA) stoke. Eligible patients will have no useful function of the paretic arm a minimum of 28 days after the ischaemic stroke (a modified NIH Stroke Scale (NIHSS) Motor Arm Score of 2, 3 or 4 for the affected arm).
Improving Arm and Hand Functions in Chronic Stroke (CIHR 2012-2015)
StrokeUpper Extremity ParesisImproving arm and hand function after stroke has been difficult to achieve within the rehabilitation service provided in the acute stage often due to the limited resource in health care. While spontaneous recovery plateaus after 6 months, the prolonged disability affects quality of life and social participation in stroke survivors. This study is aimed at improving chronic motor impairment arm and hand impairment by providing the intervention with intensive training schedule. This study will compare two types of rehabilitation intervention using a randomized controlled trial. Measurements also will be taken on various brain functions non-invasively to help discover how each of the intervention strategies works differently to repair the brain.
Virtual Occupational Therapy Application
StrokeHemiparesisVirtual Occupational Therapy Application (VOTA) combines low-cost human motion tracking, commercial game engine technology, and evidence-based Occupational Therapy (OT) practice in a computer-based virtual world in which stroke patients practice activities of daily living (ADLs). The protocol investigates the efficacy of VOTA therapy for Upper Extremity (UE) motor recovery and assesses system usability and user acceptance.
