Filter by:Post stroke delirium is prevalent in 10-30% of all stroke patients. We aimed to investigate wether Melatonin 2mg may prevent post stroke delirium.
The purpose of this randomized, controlled study is to collect performance data on the ability of an investigational device designed to digitally deliver Rhythmic Auditory Stimulation to improve walking speed in people who suffered a stroke greater than six (6) months in the past and who are limited in mobility outside the home. The primary outcomes will be the mean change in walking speed (meters per second) and mean percent change in walking speed as determined by a 10-meter Walk Test after five weeks of intervention and compared between groups.
Evidence regarding the role of early (<24 hours) antithrombotics post-revascularization with either intravenous thrombolysis (IVT), endovascular thrombectomy (EVT), or a combination of both remains scarce. In 2018 the American Heart Association/American Stroke Association changed their recommendation, stating that the risk of antithrombotic therapy within the first 24 hours after treatment with IVT (with or without EVT) is uncertain. This was changed after data emerged that early antithrombotics may be safe and may improve outcomes in select patients undergoing EVT. Recently the investigators showed for the first time that significant residual basilar thrombus can exist after EVT despite complete angiographic revascularization using endovascular optical coherence tomography imaging. This residual thrombus could cause ongoing function-limiting strokes with occlusion of vital basilar perforators after EVT. Therefore, the investigators propose a prospective,non-randomized safety study to evaluate optical coherence tomography guided antithrombotic management for patients with confirmed residual thrombus after EVT for basilar occlusion.
Background: The outcome of ischemic stroke is related to the brain lesion volume and this volume of infarction is directly related to the time to reperfusion, which therefore depends on the time to initiation of therapy. Acute ischemic stroke is treated medically with the administration of intravenous rtPA, but recent randomized controlled trials have shown the efficacy of mechanical thrombectomy and is now the new gold standard in ischemic stroke. This new therapeutic strategy has created two possibilities for pre-hospital decision-making: i/ transport the patient directly to the nearest stroke unit to receive alteplase and then if indicated perform a thrombectomy (drip and ship) or ii/ bypassing thrombolysis centres in favour of endovascular thrombectomy (mothership). Objective: To compare cost/effectiveness of transfer to the closest local stroke centre or telemedicine hub to direct transfer to the comprehensive stroke cent(CSC) in patients acute stroke with suspected large vessel occlusion. Medical and economic expected impact: We hypothesize that direct transportation to CSC is associated with better clinical outcome in case of acute ischaemic stroke due to intracranial large vessel occlusion. However, we have to demonstrate that this approach is not associated with time from onset harm in patients not eligible to mechanical thrombectomy.
Context Dance is an intrinsically motivating activity comprising social interaction, stimulation through music, the joy of moving despite motor limitations induced by pathology, and which has good perceived benefits among participants. Moving with pleasure is essential to finding the motivation to engage in rehabilitation program and physical activity. In stroke context, physical activity and rehabilitation were difficult to carry out because of cognitive and motor disabilities. Moreover, when the rehabilitation is over, the diminishing motor stimulation gradually limits autonomy in daily tasks. It is therefore urgent to provide persons in a post-stroke situation with motivating physical activity opportunities. Very few studies have studied dance in a context of stroke, while this physical activity is highly adapted and effective for other chronic conditions. Objectives: The main objective is to assess the effects of dance practice on cognitive and motor functions for persons after stroke. The secondary objective is to investigate the effects of dance on quality of life, motivation and adherence. The investigator's hypothesis is that the practice of dance induces an increase of balance and motor capacities, and improving the quality of life, adherence and motivation after a stroke. Materials and method : Forty-eight subjects with stroke in subacute phase will be randomized into two groups: 1) intervention (dance and standard rehabilitation) and 2) control (standard rehabilitation). Before intervention, stroke severity, cognitive abilities and motor capacities will be tested. Two baseline tests will occur to assess the stability of individuals will be planned. Participants will attend a dance class weekly during 6 weeks. The cognitive and motor functions (balance, lower-limbs strength, coordination and motor level), the quality of life (Stroke-specific quality of life scale) will be measured at 4 and 6 weeks in both groups. Participant satisfaction with regard to dance will be tested, as well as adherence and adverse effects. Perspectives: The joy of dancing and the possibility of including other non-disabled people should facilitate adherence and motivation and increase the recovery of cognitive and motor functions.This project should motivate physiotherapists and dance teachers to increase the offer of dance classes for persons with motor and cognitive impairments.This action will be a basis for combating people's sedentary lifestyle after a stroke.
Hemiparesis is a common motor disorder after a stroke. The majority of patients do not recover functional use of their paretic upper limb. The use of mirror therapy allows the activation of the mirror neurons involved to stimulate brain plasticity after brain damage.The IVS (Intensive Visual Stimulation) device allows an easy implementation of mirror therapy by filming the valid upper limb and projecting the inverted image onto a screen placed above the parietal arm thus producing the illusion of movement of the parietal arm. The main hypothesis of this study is that the structured practice of a large number of upper limb targeted movement repetitions using an intensive visual numerical simulation device as a partial replacement for routine care (conventional occupational therapy) in the sub-acute phase of stroke will increase the active function (motor function and functional abilities) of the distal end of the upper limb compared to conventional rehabilitation. Objectives: This randomized controlled trial will evaluate the effects of partial substitution of routine care (occupational therapy) by structured movement repetition programs by Intensive Visual Simulation using an IVS3 device, on the distal motor control of the upper hemiparesis limb, between 4 and 10 weeks after the stroke, compared to a program with conventional care alone.
Observational study of functional recovery of stroke patients after discharge from rehabilitation
This study attempts to minimize the development of a common movement impairment following stroke known as "flexion synergy" that makes it extremely difficult to reach outward with the arm. Participants with acute/subacute stroke will receive one of two study interventions in addition to prescribed therapies in both inpatient rehabilitation and day-rehab. Participants will be followed for 1 year.
The purpose of this study is to establish a methodological framework based on existing advanced neuroimaging technologies as a new clinical neuroimaging tool for assessment of possible affected brain connections in stroke and TIA patients. Thus, providing new insights into microstructural changes that may underline why those patients experience deficits like fatigue.
Objective: The goal of this study is to implement and test a neuro-mechanical gait assist (NMGA) device to correct walking characterized by muscle weakness, incoordination or excessive tone in Veterans with hemiparesis after stroke that adversely affects their ability to walk, exercise, perform activities of daily living, and participate fully in personal, professional and social roles. Research Plan: A prototype NMGA device will be used to develop a finite state controller (FSC) to coordinate each user's volitional effort with surface muscle stimulation and motorized knee assistance as needed. Brace mounted sensors will be used to develop a gait event detector (GED) which will serve the FSC to advance through the phases of gait or stair climbing. In addition, a rule-base intent detection algorithm will be developed using brace mounted sensors and user interface input to select among various functions including walking, stairs climbing, sit-to-stand and stand-to-sit maneuvers. The FSC controller tuning and intent algorithm development and evaluation will be on pilot subjects with difficulty walking after stroke. Outcome measures during development will provide specifications for a new prototype NMGA design which will be evaluated on pilot subjects to test the hypothesis that the NMGA improves walking speed, distance and energy consumption of walking. These baseline data and device will be used to design a follow-up clinical trial to measure orthotic impact of NMGA on mobility in activities of daily living at home and community. Methodology: After meeting inclusion criteria, pilot subjects will undergo baseline gait evaluation with EMG activities of knee flexors and extensors, ankle plantar and dorsiflexors and isokinetic knee strength and passive resistance. They will be fitted with a NMGA combining a knee-ankle-foot-orthosis with a motorized knee joint and surface neuromuscular stimulation of plantar- and dorsi- flexors, vasti and rectus femoris. Brace mounted sensor data will be used for gait event detector (GED) algorithm development and evaluation. The GED will serve the FSC to proceed through phases of gait based on supervisory rule-based user intent recognition algorithm detected by brace mounted sensors and user input interface. The FSC will coordinate feed-forward control of tuned stimulation patterns and closed-loop controlled knee power assist as needed to control foot clearance during swing and stability of the knee during stance. Based on data attained during controller development and evaluation, a new prototype NMGA will be design, constructed and evaluated on pilot subjects to test the hypothesis that a NMGA device improves safety and stability, increases walking speed and distance and minimizes user effort. Clinical Significance: The anticipated outcome is improved gait stability with improved swing knee flexion, thus, increasing the safety and preventing injurious falls of ambulatory individuals with hemiplegia due to stroke found in large and ever-increasing numbers in the aging Veteran population. Correcting gait should lead to improved quality of life and participation.
