The purpose of this registry is to collect performance and safety data on the Penumbra System including the 3D Revascularization Device in a real world patient population with acute ischemic stroke (AIS) secondary to intracranial large vessel occlusion (LVO).
Background and Rationale: Every year, more than a 15 million people worldwide suffer a stroke1. Despite laborious rehabilitation programs 70% of those stroke patients still show limited gait ability after three months. Numerous RCTs have shown the superiority of over ground gait training and electromechanical-assisted gait devices in comparison with conventional over ground gait training alone. (Jan Mehrholz, Elsner, Werner, Kugler, & Pohl, 2013) However, most of these trials used the electromechanical-assisted gait devices in a very high frequency which is almost impossible to achieve in daily clinical routine. Therefore, the effect of a practice-oriented physical therapy protocol including electromechanical-assisted gait training remains unclear. Objective(s): The aim of this clinical trial is to investigate the effects of an integrated, practice-orientated individual physical therapy protocol with or without electromechanical-assisted gait training in subacute stroke patients, respectively. The effects of both physical therapy protocols will be compared with validated assessments covering the different components of the ICF framework: function, activity and participation. Primary objectives: Effects on gait ability and on basic activities of daily living (ADL). Secondary objectives: Effects on walking speed, walking capacity, functional mobility, muscle force, spasticity and reintegration to normal living (RNLI). Furthermore, different training-related data are recorded to capture the efficiency (intensity and hassle) of both physical therapy protocols.
This study evaluates the safety and tolerability of 3 dose levels of ABL-101 and supplemental oxygen in acute stroke patients.
The aims of this project are to: 1. investigate the adherence and persistence to anticoagulation (and in specific, to VKAs and NOACs) in AF patients with previous ischemic stroke; 2. identify predictors of poor adherence and persistence and 3. assess whether the SAMe-TT2R2 score predicts adherence and persistence to anticoagulation

Emerging evidence demonstrates that animals and people can exert control over the level of excitability in spinal and corticospinal neural circuits that contribute to movement. This discovery has important implications, as it represents a new strategy to improve motor control in people of all ability levels, including those with neurological conditions. Operant conditioning is a well-studied mechanism of learning, in which the modification of a behavior can be brought about by the consequence of the behavior, and reinforcement causes behaviors to become more frequent. In recent years, operant conditioning has been applied to spinally-mediated reflex responses in mice, rats, monkeys and people. By electrically stimulating a peripheral nerve, recording the muscle response, and rewarding responses that are within a desirable range, it is possible to increase or decrease the neural circuit's excitability. This may alter the level of resting muscle tone and spasticity, as well the muscle's contribution to planned movements and responses to unexpected events. Operant conditioning of spinal reflexes has been applied to a lower limb muscle in healthy people and those with spinal cord injuries. In this project, we will expand the use of operant conditioning to muscles of the upper limb, demonstrating feasibility and efficacy in healthy people and people post-stroke. We will determine whether operant conditioning can be used to decrease excitability of spinal reflexes that activate a wrist flexor muscle. Additionally, in a separate group of healthy people, we will determine whether operant conditioning can be used in a similar way to increase corticospinal excitability. We will stimulate the motor cortex with transcranial magnetic stimulation to elicit motor evoked potentials in the same wrist flexor muscle, and will reward responses that exceed a threshold value. We will examine the effects of these interventions on motor control at the wrist, using an innovative custom-designed cursor-tracking task to quantify movement performance. We will determine whether changes in spinal reflex excitability or corticospinal excitability alter motor control. The overall goal of this research is to develop a new, evidence-based strategy for rehabilitation that will improve recovery of upper limb function in people after stroke.
The aim of this study is to investigate the most effective stimulation site in transcranial direct current stimulation for gait recovery after stroke. All subjects will go through four conditions of transcranial direct current stimulation with for 30 minutes. Four conditions are 1) bihemispheric stimulation - anodal stimulation on both ipsilesional and contralesional leg area of primary motor cortex and supplementary motor area. 2) ipsilesional stimulation - anodal stimulation on ipsilesional leg area of primary motor cortex and supplementary motor area. 3) contralesional stimulation - anodal stimulation on contralesional leg area of primary motor cortex and supplementary motor area. 4) sham stimulation. Subjects will walk on treadmill for 10 minutes during transcranial direct current stimulation. Motor evoked potential and functional evaluations will be done before and after stimulation to measure the changes.
The aim of the current protocol is to study 40 patients, each for 12 weeks, to address hypotheses related to the ability of a telerehabilitation system to (a) improve motor status and disability, (b) collect various forms of patient data from the home, (c) improve risk factor knowledge and control, and (d) assess patient compliance with home-based telerehabilitation. Patients who have returned to their home after stroke will be provided with a telehealth system and be asked to use it 6 days/week for 12 weeks, during which time subjects will use this system for daily rehabilitation therapy, assessments, and education--all on one platform.
Spasticity is part of the syndrome motor neuron following a Stroke. It is a clinical sign of great complexity that generates disability, limiting the function and altering the quality of life of the subjects, generating great impact on families and society. Identify times and characteristics of appearance; as well as its predictive factors can support an early intervention, orienting and strengthening the work of the rehabilitation team. Determine the times of establishment, location and factors that favor the development of spasticity in acute stage and how it influences the functionality, quality of life and emotional level of post-stroke patients in hospital facilities. Through this proposal, it is proposed to generate a new line of research that allows the development of scientific evidence in the area of neurorehabilitation, specifically in the field of spasticity, through the identification of establishment times, affected structures and predominant patterns in the extremities; as well as determining factors that favor the development of spasticity and its impact on post-stroke functionality and quality of life. This information will strengthen the rehabilitative process of these subjects and the actions of the rehabilitation team, supporting the identification of preventive measures and implementing effective interventions that allow achieving better motor and functional results, in search of an optimal recovery.
