IMPRESS study aims to describe the immuno-inflammatory and thrombo-inflammatory profiles during the first 24/36 hours of treatment of patients suffering from AIC treated with TM, and to study the possible impact of these profiles on the functional prognosis at 3 months of AIC treatment.
The purpose of this study is to develop a real-time controller for exoskeletons using neural information embedded in human musculature. This controller will consist of an online interface that anticipates human movement based on high-density electromyography (HD-EMG) recordings, and then translates it into functional assistance. This study will be carried out in both healthy participants and participants post-stroke. The researchers will develop an online algorithm (decoder) in currently existing exoskeletons that can extract hundreds of motor unit (MU) spiking activity out of HD-EMG recordings. The MU spiking activity is a train of action potentials coded by its timing of occurrence that gives access to a representative part of the neural code of human movement. The researchers will also develop a command encoder that can anticipate human intent (multi-joint position and force commands) from MU spiking activity to translate the neural information to movement. The researchers will integrate the decoder with the command encoder to showcase the real-time control of multiple joint lower-limb exoskeletons.
Intracerebral hemorrhage (ICH) results from the rupture of small vessels damaged by chronic hypertension, amyloid angiopathy or other disease. Currently, ICH has been a devastating type of stroke that lacking effective therapy. Remote ischemic conditioning (RIC), a systematically protective strategy, has been found to have neuroprotective effects by in patients with ischemic stroke. In addition, animal studies show that RIC is safe in ICH model and it could accelerate the absorption of hematoma. In a previous clinical study (RICH-1), RIC have been found to be safe and well-tolerated in patients with ICH. Therefore, the investigators plan to undertake this study to further evaluate the safety and efficacy of RIC in patients with ICH. The investigators hypothesize that treatment with RIC will accelerate the absorption of hematoma and improve patients' functional outcomes. Results of this study can potentially bring into account new means to improve the outcomes of ICH patients.
This project is to evaluate and compare the impact of tDCS stimulation location on augmenting MT effects.
Among subacute stroke patients (within 4 weeks after the onset), patients who are unable to walk are divided into experimental groups and control groups, and conventional rehabilitation treatment including physical therapy and occupational therapy is performed for 4 weeks or more in all groups. Robot assisted inclined bed treatment and FES were performed, and the control group performed conventional inclined bed treatment. The purpose of this study is to investigate the effect of robot-assisted inclined bed treatment by tracking observation and comparative analysis of the lower limb function, gait ability, bone density and muscle mass of each group. Patients appropriate for the selection criteria are divided into experimental group and control group in random permuted blocks to conduct the study. In the experimental group, FES was performed at the same time as the robot-assisted inclined bed treatment once a day for 30 minutes, 5 days a week for 4 weeks, and the control group performed conventional inclined bed treatment for 30 minutes once a day for 4 weeks, 5 days a week. Separately from this in all groups, functional electrical stimulation treatment is performed once a day in the area except the lower extremities. In addition, all patients receive palliative physical therapy for 4 weeks for 1 hour a day. All subjects undergo a physical examination and whole body composition assessment before and after 4 weeks of treatment, and f/u after 4 weeks of treatment.
In order to reduce the incidence of fractures due to osteopenia, osteoporosis, and bone mineral density in first stroke patients, the purpose of this study was to determine whether it is meaningful to administer zoledronic acid prophylactically, and to define the characteristics of the patient group that can benefit. Subjects suitable for the selection criteria are divided into an experimental group (zoledronic acid group) and a control group (physiological saline group) in random permuted blocks. Random assignment means that a coin is thrown and assigned to the experimental group or the control group with the probability of a head or tail, and is assigned using a random number table. The comparison-control group was designed to analyze and compare whether there is a significant effect of preventing the decrease in bone density in the group administered zoledronic acid through the double-blind experimental group and the control group. The reason why physiological saline was selected as a reference drug was to double-blind with zoledronic acid, because it does not affect the subject's bone density and has a very low possibility of side effects, and its transparent properties are similar to that of zoledronic acid. Subjects undergo a bone density (BMD-Spine and femur, Whole Body Composition Assessment) test using DEXA (dual energy x-ray absorptiometry) through outpatient or hospitalization at the Department of Rehabilitation within one month after the onset of stroke. Subsequently, the subject will receive a single infusion of zoledronic acid 5mg/100mL or physiological saline 100mL intravenously at the outpatient or inpatient ward depending on the group. Subsequently, the subject will receive a single infusion of zoledronic acid 5mg/100mL or physiological saline 100mL intravenously at the outpatient or inpatient ward depending on the group. Each subject or guardian fills in the questionnaire form at the time of the first injection, 6 months and 12 months after the injection, and immediately sees the fractures, side effects, and changes in drugs taken from the last survey to the present. At the first injection, 6 months and 12 months after the injection, the above examination (bone density) is performed through an outpatient department of rehabilitation medicine, and by type known to be related to zoledronic acid administration such as fractures during the period (primary fragile fracture, non-spine fragile fracture, Symptom fracture, spine fracture, etc.)
The purpose of this study is to compare and analyze how the visual gaze training in the afferent direction and the visual gaze training in the efferent direction using virtual reality affects the improvement of the neglect phenomenon in patients with subacute stroke with unilateral neglect. Based on the behavioral intention test (BIT) test and the Mini-Mental Screening Examination test (MMSE) test for the group of unilateral neglected patients with stroke findings among all eligible patients for this experiment. Appropriate subjects are selected and randomly divided into two groups. One group uses an afferent virtual reality program, and the other uses an efferent virtual reality program to train five times a week for a total of 4 weeks. Before training, a computer experience scale 21 was additionally performed, and to find out the degree of unilateral negligence, evaluation was performed using the Behavioral Inattention Test (BIT) and Catherine Bergego Scale (CBS)22, and the angle of deflection (deviation angle), out-of-focus time, gaze time, failure rate, and head rotation trajectory were evaluated. In addition, reaction time, failure rate, and head rotation trajectory were evaluated using a virtual reality program (Assessment program-V2) to evaluate the degree of unilateral negligence. After that, BIT, CBS, and Assessment program-V2 tests are performed to determine the degree of improvement in visual ignorance due to each program.

The exact function of the anterior cingulate cortex (ACC) is one of the largest riddles in cognitive neuroscience and a major challenge in mental health research. ACC dysfunction contributes to a broad spectrum of neurological and psychiatric disorders, such as depression, ADHD, Parkinson's disease, OCD and many others, but nobody knows what it actually does. Recently a new theory has been developed about ACC function; the HRL-ACC (Hierarchical Reinforcement Learning Theory of ACC). This theory proposes that the ACC selects and motivates high-level tasks based on the principles of hierarchical reinforcement learning. The ACC associates values with tasks (these values are based on the reward positivity produced by the midbrain dopamine system), selects the correct tasks and applies control over other neural networks (such as the dorsolateral prefrontal cortex and basal ganglia), which execute the tasks. The goal of this study is to investigate the consequences of ACC damage (and other areas of the frontal lobe) on task regulation within a group of patients who have suffered a stroke in the frontal lobe. Furthermore, the correlation between ACC damage and mood disorders such as depression and apathy is going to be investigated.
