Abstract
Introduction The Covid 19 pandemia since the first reported case in 2019 had a direct socioeconomic impact related to morbi-mortality and indirect in response to protection and isolation strategies. To our knowledge thrombo-embolic complications can be a mode of revelation complicating the management. Case presentation We present an exceptional case of a patient with a history of Covid 19,admitted 21 days later for disturbed consciousness, in whom an ischemic occipital stroke ,intestinal and colonic ishemia had been objectified. Our objective through this presentation is to remind the thrombo-embolic particularity of Covid 19, to take the viral attack as a serious antecedent in the periods following theinfection and to put the point on the primordial place of early rehabilitation in patients with stroke. Discussion and Conclusion We discuss through this report the recommendations of anticoagulation in Covid 19 patients and the place of early rehabilitation in patients with stroke. We also report a new case among the rare cases described in the literature that associates several thrombo-embolic manifestations secondary to Covid 19, in particular the neurological and digestive association. Exceptional Clinical Presentation associating an occipital Stroke, a Superior and Inferior Mesenteric Thrombosis following Covid 19 Disease. We propose take to the viral attack as a serious antecedent. This manuscript can add new perspectives to the management practice of this very rare presentation.

Abstract
Abstract
Background
NeuroAid II (MLC901) is a promising therapy for stroke patients who present outside of therapeutic window for reperfusion therapy. Studies have proven its efficacy in ischemic stroke; however, data of drug safety and combination with other medications especially anticoagulants are heterogenous. We report a possible case of hepatotoxicity induced by NeuroAid II in combination with anticoagulants.
Case presentation
We report an elderly patient who developed symptoms of cardioembolic stroke presented outside of time window for reperfusion therapy. He was started on a regiment of statins, anticoagulation, beta blockers and NeuroAid II. One month later he presented with deranged liver enzymes. Cessation of NeuroAid II resulted in rapid improvement of transaminitis within days.
Conclusions
We wish to highlight the potential harmful effect of administering NeuroAid II with an anticoagulant and the importance of routine follow-up and blood monitoring in the elderly patients with stroke.

Abstract
To provide stroke patients with good rehabilitation training, the rehabilitation robot should ensure that each joint of the limb of the patient does not exceed its joint range of motion. Based on the machine vision combined with an RGB-Depth (RGB-D) camera, a convenient and quick human-machine interaction method to measure the lower limb joint range of motion of the stroke patient is proposed. By analyzing the principle of the RGB-D camera, the transformation relationship between the camera coordinate system and the pixel coordinate system in the image is established. Through the markers on the human body and chair on the rehabilitation robot, an RGB-D camera is used to obtain their image data with relative position. The threshold segmentation method is used to process the image. Through the analysis of the image data with the least square method and the vector product method, the range of motion of the hip joint, knee joint in the sagittal plane, and hip joint in the coronal plane could be obtained. Finally, to verify the effectiveness of the proposed method for measuring the lower limb joint range of motion of human, the mechanical leg joint range of motion from a lower limb rehabilitation robot, which will be measured by the angular transducers and the RGB-D camera, was used as the control group and experiment group for comparison. The angle difference in the sagittal plane measured by the proposed detection method and angle sensor is relatively conservative, and the maximum measurement error is not more than 2.2 degrees. The angle difference in the coronal plane between the angle at the peak obtained by the designed detection system and the angle sensor is not more than 2.65 degrees. This paper provides an important and valuable reference for the future rehabilitation robot to set each joint range of motion limited in the safe workspace of the patient.

Abstract
Neurologic manifestations associated with a coronavirus disease 2019 (COVID‐19) diagnosis are common and often occur in severe and critically ill patients. In these patients, the neurologic symptoms are confounded by critical care conditions, such as acute respiratory distress syndrome (ARDS). Patients with dual diagnoses of COVID‐19 and neurologic changes such as myopathy, polyneuropathy, and stroke are likely at a higher risk of experiencing deficits with swallowing, communication, and/or cognition. Speech‐language pathologists are an integral part of both the critical care and neurologic disorders multi‐disciplinary teams, offering valuable contributions in the evaluation, treatment, and management of these areas. Patients in intensive care units (ICUs) who require mechanical ventilation often experience difficulty with communication and benefit from early speech‐language pathology intervention to identify the most efficient communication methods with the medical team and caregivers. Moreover, patients with neurologic manifestations may present with cognitive‐linguistic impairments such as aphasia, thereby increasing the need for communication‐based interventions. Difficulties with voice and swallowing after extubation are common, often requiring frequent treatment sessions, possibly persisting beyond ICU discharge. After leaving the ICU, patients with COVID‐19 often experience physical, cognitive, and mental health impairments collectively called post‐intensive care syndrome. This is often a lengthy road as they progress toward full recovery, requiring continued speech‐language pathology treatment after hospital discharge, capitalizing on the principles of neuroplasticity.

Abstract
Background and Objectives: This study was conducted to determine whether self-control and emotions could influence patients' physical ability and functional recovery after stroke. Materials and Methods: Twenty-four patients within eight weeks after a stroke were included in this study (age: 54.04 ± 10.31; days after stroke: 42.66 ± 8.84). The subjects participated in tests at the baseline, four weeks later, and eight weeks later. Subjects were asked to complete the following: (1) self-control level test, (2) positive and negative emotion test, (3) knee muscle strength testing, (4) static balance test, (5) gait measurement, and (6) activities of daily living evaluation. Results: The muscle strength of the knee, static balance, gait ability, and the Functional Independence Measure score increased significantly in the stroke patients over time. A significant correlation was noted between the emotion and physical variables in stroke patients. The self-control level was significantly associated with the change in the physical variables in stroke patients over time. Conclusions: The self-control level was positively related to the increases in functional recovery of stroke patients with time, while the emotions were related more to the physical abilities.

Abstract
Carrying out the immediate rehabilitation interventional therapy will better improve the curative effect of rehabilitation therapy, after the condition of bedridden stroke patients becomes stable. A new lower limb rehabilitation training module, as a component of a synchronous rehabilitation robot for bedridden stroke patients’ upper and lower limbs, is proposed. It can electrically adjust the body shape of patients with a different weight and height. Firstly, the innovative mechanism design of the lower limb rehabilitation training module is studied. Then, the mechanism of the lower limb rehabilitation module is simplified and the geometric relationship of the human–machine linkage mechanism is deduced. Next, the trajectory planning and dynamic modeling of the human–machine linkage mechanism are carried out. Based on the analysis of the static moment safety protection of the human–machine linkage model, the motor driving force required in the rehabilitation process is calculated to achieve the purpose of rationalizing the rehabilitation movement of the patient’s lower limb. To reconstruct the patient’s motor functions, an active training control strategy based on the sandy soil model is proposed. Finally, the experimental platform of the proposed robot is constructed, and the preliminary physical experiment proves the feasibility of the lower limb rehabilitation component.

Abstract
BACKGROUND Past research has indicated that repetitive transcranial magnetic stimulation (rTMS) on the pharyngeal motor cortex may be beneficial to poststroke dysphagic patients. In addition, some studies have supported that transcranial direct current stimulation (tDCS) over the pharyngeal motor cortex can improve swallowing function in poststroke dysphagia. However, some studies showed that rTMS and tDCS show no effect on poststroke dysphagia. This study aims to make a meta-analysis to investigate the therapy effect of rTMS and tDCS on poststroke dysphagia in randomized controlled trials (RCTs). METHODS We searched for studies published before March 2021 in databases (PubMed, Web of Science, MEDLINE, EMBASE, and Google Scholar). Meta-analysis was made to compute the results of included studies using STATA 12.0 software. RESULTS The present study shows a significant increase in the swallowing function in poststroke dysphagia given rTMS compared to those given sham rTMS (standardized mean difference [SMD] = 1.08, 95% confidence interval [CI] = 0.37-1.80, I2 = 81.2%, p < 0.001). In addition, the study shows a significant increase in the swallowing function in poststroke dysphagia given tDCS (combined or not combined with conventional swallowing therapy), compared to those given sham tDCS (combined or not combined with conventional swallowing therapy) (SMD = 1.43, 95% CI = 0.73-2.13, I2 = 77.6%, p < 0.001). CONCLUSIONS The study demonstrates that rTMS and tDCS over the pharyngeal motor cortex show therapy effects on poststroke dysphagia. Many more large-scale, blinded RCTs are essential to investigate the effect of rTMS and tDCS on poststroke dysphagia.

Abstract
Objective Stroke among young adults is the leading cause of disability worldwide. Efforts are being taken to control stroke in the general population, but in parallel, there is an increasing trend of stroke among the young population. These patients are often affected by physical disability, cognitive impairment, and loss of productivity, all of which have personal, social, and economic implications. The main aim of this study was to determine the risk factors associated with stroke among young patients admitted to a tertiary care rehabilitation center and determine the effect of rehabilitation on the outcome of their daily life activities. Materials and Methods A retrospective hospital-based cohort study was conducted between January 2015 to December 2019. Prevalence of stroke-related risk factors like hypertension, hyperlipidemia, diabetes, and cardiac disease was assessed. Results Out of 710 young stroke adults, 71.97% were described as ischemic, and 28.03% reported as non-ischemic. Mean age (SD) was found to be 44.54 ± 9.3. Univariate analysis demonstrated that hyperlipidemia, cardiac disease, and diabetes indicated a significantly higher risk for ischemic stroke with an OR (95% CI) at 2.5 (1.7-3.7), 2.11 (1.2-3.6), and 1.66 (1.2-2.3) respectively. A significant improvement was observed in their Functional Independence Measure (FIM0 score after their rehabilitation irrespective of age and gender. Conclusion Association of risk factors associated with stroke should be subjected to close follow-up and management, thus reducing the risk of developing long-lasting disabilities at a young age. The identification of risk factors for young stroke incidence is a step towards improving health in the young adult population.

Abstract
Background: Studies of treatment methods for patients with acute ischaemic stroke should include aetiological causes, concomitant pathology, and localisation of the lesion, and the extent of the lesion in the brain. The purpose of the study was to determine changes in clinical and neurological parameters in patients with ischaemic stroke in the acute period. Methods: This is an open clinical study for which 240 patients were selected with an acute condition after an ischaemic stroke. All patients were divided into 4 groups (depending on the treatment). Clinical neurological examination and testing was performed upon admission to the hospital and upon discharge- after treatment. Electroencephalographic biofeedback (EEG-BFB) therapy was performed using a EEG-BSE device (Bio-Link). Data was processed according to the statistical method of experimental data assessment. Results: To study the effectiveness of treatment upon acute ischaemic stroke, a comprehensive treatment system was developed, involving acupuncture, Qigong breathing exercises, and electroencephalographic biological feedback (EEG-BIOFEEDBACK), based mainly on the mechanisms of action. The study investigated the features of the acupuncture treatment in patients with ischaemic stroke during recovery. The authors noted the degree of effectiveness of EEG-BFB therapy, Qigong therapy, acupuncture, and standard treatment. Studies revealed that the development of ischaemic stroke begins gradually and at an early age. Conclusion: It was concluded that the most effective method for treating the clinical and neurological manifestations of acute ischaemic stroke is EEG-BFB therapy, followed by acupuncture, Qigong therapy, and standard treatment.

Abstract
The risk of having a stroke event doubles each decade after the age of 55. Therefore, it is of great interest to develop neurorestorative therapies of stroke which occurs mostly in elderly people. However, to date, patients at risk for these sequels of stroke are not duly diagnosed and treated due to the lack of reliable biomarkers. Extracellular vesicles (EVs) are lipid bilayer-delimited particles that are shed by the brain cells and are able to cross the blood–brain barrier and enter the blood stream; thus, they may be used to interrogate molecular and cellular events in the brain damaged area. In this review, we summarize the major molecular and cellular responses of astroglia and neurons to cerebral ischemia and assess their impact on post-stroke recovery and rehabilitation. In particular, we ask if EVs secreted by brain cells are responses to cerebral ischemia, and they may shed new light on the interplay between exosomes-mediated interactions between brain cells and the question of how to exploit it in order to predict the individual course of the disease and to introduce specific preventive or therapeutic strategies. Given these findings, we are left with two options: either to (i) transplant neuronal precursors into the damaged cortical area or (ii) to covert abundantly present proliferating astrocytes in the perilesional area into neurons by using recently developed genetic technologies. However, given the complexity of molecular and cellular responses to cerebral ischemia and our limited capabilities to restore brain structure and function, we are left with only one realistic aim: to invest more in prevention.

Abstract
Stem cell transplantation with rehabilitation therapy presents an effective stroke treatment. Here, we discuss current breakthroughs in stem cell research along with rehabilitation strategies that may have a synergistic outcome when combined together after stroke. Indeed, stem cell transplantation offers a promising new approach and may add to current rehabilitation therapies. By reviewing the pathophysiology of stroke and the mechanisms by which stem cells and rehabilitation attenuate this inflammatory process, we hypothesize that a combined therapy will provide better functional outcomes for patients. Using current preclinical data, we explore the prominent types of stem cells, the existing theories for stem cell repair, rehabilitation treatments inside the brain, rehabilitation modalities outside the brain, and evidence pertaining to the benefits of combined therapy. In this review article, we assess the advantages and disadvantages of using stem cell transplantation with rehabilitation to mitigate the devastating effects of stroke.

Clinical Evaluation of Different Treatment Strategies for Motor Recovery in Poststroke Rehabilitation during the First 90 Days. J Clin Med 2021; 10:jcm10163718. [PMID: 34442014 PMCID: PMC8396898 DOI: 10.3390/jcm10163718] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2021] [Revised: 08/10/2021] [Accepted: 08/15/2021] [Indexed: 11/28/2022] Open
Abstract
Background: Motor recovery after stroke is based on neuronal plasticity and the structural reorganization of the brain. Questions are debated about the proper moment to start rehabilitation in the acute period of stroke, the significance of rehabilitation interventions during the so-called “plastic window”, and the advantages of modern and traditional programs. The aims of this study were to evaluate the role of different rehabilitation strategies and their combinations for motor recovery and the impact on functional disability by way of neurological and functional outcomes 3 months after ischemic stroke. Methods: We used three rehabilitation approaches: early rehabilitation from the first day of stroke (Phase I), traditional exercise programs (Phase II), and an author’s new method of biofeedback rehabilitation using motion sensors and augmented reality (AR) rehabilitation (Phase III). Clinical and functional outcomes were measured on the 90th day after stroke. We developed algorithms for quantifying the quality of movements during the execution of tasks in the motor domains of the AR rehabilitation program. Results: Phase I of rehabilitation led to an improvement in functional independence, and the recovery of motor functions of the extremities with an absence of mortality and clinical deterioration. AR rehabilitation led to significant improvement both with respect to clinical and functional scores on scales and to variables reflecting the quality of movements. Patients who were actively treated during Phases II and III achieved the same final level of motor recovery and functional outcomes as that of participants who had only received AR rehabilitation during Phase III. Patients who underwent outpatient observation after Phase I showed a deficit of spontaneous motor recovery on the 90th day after stroke. Conclusions: Early rehabilitation was successful but was not enough; rehabilitation programs should be carried out throughout the entire “sensitive period” of poststroke plasticity. The newly developed AR biofeedback motion training is effective and safe as a separate rehabilitation method in the early recovery period of moderately severe, hemiparalytic, and ischemic stroke. These two rehabilitation approaches must be applied together or after each other, not instead of each other, as shown in clinical practice.

Abstract
BACKGROUND The evidence of early mobilization after stroke is conflicting, and the recovery period is an important concern. OBJECTIVE To analyse the functionality, quality of life and disability at 90 days and 1 year post-stroke of patients who received a Very Early Mobilization Protocol (VEMP). METHODS Prospective cohort study in a tertiary stroke unit. Consecutive patients aged≥18 years and without prior significant disability, who presented motor deficit after acute stroke, were included. A symmetry test was performed to compare the changes in the main variables: Barthel Index (BI), Functional Ambulation Category (FAC), modified Rankin Scale (mRS) and EuroQol five-dimensions three-level (EQ-5D-3L) between 90 days and 1 year post-stroke. RESULTS A total of 123 patients were recruited. The BI reflected an improvement at 1 year in transfer to chair/bed in 25.8%(p < 0.01) of patients and in toilet use in 25.8%(p = 0.02). The FAC showed an improvement at 1 year in 44.4%(p < 0.01) of patients and the mRS in 19.1%(p = 0.01). The usual activities dimension of the EQ-5D-3L showed a clinically relevant improvement after 1 year in 15.9%(p = 0.23) of patients. CONCLUSIONS A significant percentage of patients show improvements in some functional areas and in disability between 90 days and 1 year post-stroke.

Abstract
BACKGROUND Studies demonstrate the benefits of upper limbs cycle ergometer (ULCE) in subacute and chronic stroke subjects, but the literature still needs to explore the acute phase of the disease. OBJECTIVE Verify the effects of ULCE on muscular strength, trunk control and independence of post-stroke subjects in hospital acute phase. METHODS In this randomized clinical trial participants were allocated into two groups. The control group (CG) performed two daily sessions of conventional physiotherapy, while the intervention group (IG) had one daily session of conventional physiotherapy and one of ULCE. The interventions were carried out for 20 minutes for five days. Both groups were assessed before and after the treatment for upper limbs strength by manual dynamometer, trunk control by Trunk Impairment Scale and level of independence by the Modified Rankin Scale. RESULTS Twenty subjects with mean ages of 63.5±4.5 were enrolled. There was a significant intra-group difference of palmar grip, shoulder abductors, elbow flexor and wrist extensor strength, trunk control and functional independence only in IG. Inter-group difference for all variables showed superiority in IG. CONCLUSIONS ULCE is an effective device for increasing muscle strength, trunk control and consequently improving the independence of post-stroke subjects in the acute hospital phase.

Abstract
A network of cholinergic neurons in the basal forebrain innerve the forebrain and are proposed to contribute to a variety of functions including cortical plasticity, attention, and sensorimotor behavior. This study examined the contribution of the nucleus basalis cholinergic projection to the sensorimotor cortex on recovery on a skilled reach-to-eat task following photothrombotic stroke in the forelimb region of the somatosensory cortex. Mice were trained to perform a single pellet skilled reaching task and their pre and poststroke performance, from Day 4 to Day 28 poststroke, was assessed frame-by-frame by video analysis with endpoint, movement and sensorimotor integration measures. Somatosensory forelimb lesions produced impairments in endpoint and movement component measures of reaching and increased the incidence of fictive eating, a sensory impairment in mistaking a missed reach for a successful reach. Upregulated acetylcholine (ACh) release, as measured by local field potential recording, elicited via optogenetic stimulation of the nucleus basalis improved recovery of reaching and improved movement scores but did not affect sensorimotor integration impairment poststroke. The results show that the mouse cortical forelimb somatosensory region contributes to forelimb motor behavior and suggest that ACh upregulation could serve as an adjunct to behavioral therapy for acute treatment of stroke.

The Effectiveness of Additional Core Stability Exercises in Improving Dynamic Sitting Balance, Gait and Functional Rehabilitation for Subacute Stroke Patients (CORE-Trial): Study Protocol for a Randomized Controlled Trial. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18126615. [PMID: 34205457 PMCID: PMC8296367 DOI: 10.3390/ijerph18126615] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/13/2021] [Revised: 06/15/2021] [Accepted: 06/16/2021] [Indexed: 11/24/2022]
Abstract
Background: Trunk impairment produces disorders of motor control, balance and gait. Core stability exercises (CSE) are a good strategy to improve local strength of trunk, balance and gait. Methods and analysis: This is a single-blind multicenter randomized controlled trial. Two parallel groups are compared, and both perform the same type of therapy. A control group (CG) (n = 110) performs conventional physiotherapy (CP) (1 h per session) focused on improving balance. An experimental group (EG) (n = 110) performs CSE (30 min) in addition to CP (30 min) (1 h/session in total). EG is divided in two subgroups, in which only half of patients (n = 55) perform CSE plus transcutaneous electrical nerve stimulation (TENS). Primary outcome measures are dynamic sitting, assessed by a Spanish version of Trunk Impairment Scale and stepping, assessed by Brunel Balance Assessment. Secondary outcomes are postural control, assessed by Postural Assessment Scale for Stroke patients; standing balance and risk of fall assessed by Berg Balance Scale; gait speed by BTS G-Walk (accelerometer); rate of falls, lower-limb spasticity by Modified Ashworth Scale; activities of daily living by Barthel Index; and quality of life by EQ-5D-5L. These are evaluated at baseline (T0), at three weeks (T1), at five weeks (end of the intervention) (T2), at 17 weeks (T3) and at 29 weeks (T4). Study duration per patient is 29 weeks (a five-week intervention, followed by a 24-week post-intervention).

Abstract
Despite randomized trials showing a functional outcome benefit in favor of endovascular therapy (EVT), large artery occlusion acute ischemic stroke is associated with high mortality. We performed a retrospective analysis from a prospectively collected code stroke registry and included patients presenting between November 2016 and April 2019 with internal carotid artery and/or proximal middle cerebral artery occlusions. Ninety-day mortality status from registry follow-up was corroborated with the Social Security Death Index. A multivariable logistic regression model was fitted to determine demographic and clinical characteristics associated with 90-day mortality. Among 764 patients, mortality rate was 26%. Increasing age (per 10 years, OR 1.48, 95% CI 1.25-1.76; p < 0.0001), higher presenting NIHSS (per 1 point, OR 1.05, 95% CI 1.01-1.09, p = 0.01), and higher discharge modified Rankin Score (per 1 point, OR 4.27, 95% CI 3.25-5.59, p < 0.0001) were independently associated with higher odds of mortality. Good revascularization therapy, compared to no EVT, was independently associated with a survival benefit (OR 0.61, 95% CI 0.35-1.00, p = 0.048). We identified factors independently associated with mortality in a highly lethal form of stroke which can be used in clinical decision-making, prognostication, and in planning future studies.

Abstract
Objective: Exercise rehabilitation is an effective therapy in reducing the disability rate after stroke and should be carried out as early as possible. However, very early rehabilitation exercise exacerbates brain injury and is difficult to conduct in stroke patients due to their weakened and potentially disabled state. It is valuable to explore additional early rehabilitation strategies. Remote Ischemic Conditioning (RIC) is a novel therapy designed to protect vital organs from severe lethal ischemic injury by transient sublethal blood flow to non-vital organs, including the distal limbs, in order to induce endogenous protection. RIC has previously been conducted post-stroke for neuroprotection. However, whether combined early RIC and exercise (RICE) therapy enhances stroke rehabilitation remains to be determined. Methods: This is a single-center, double-blinded, randomized controlled trial that will enroll acute ischemic stroke patients within 24 h of symptom onset or symptom exacerbation. All enrolled patients will be randomly assigned to either the RICE group (exercise with RIC) or the control group (exercise with sham RIC) at a ratio of 1:1, with 20 patients in each group. Both groups will receive RIC or sham RIC within 24 h after stroke onset or symptom exacerbation, once a day, for 14 days. All patients will begin exercise training on the fourth day, twice a day, for 11 days. Their neurological function [Modified Rankin Scale (mRS) score, National Institutes of Health Stroke Scale (NIHSS) score, Barthel Index, and walking ability], infarct volume (nuclear magnetic resonance, MRI), and adverse events will be evaluated at different time points in their post-stroke care. Results: The primary outcome is safety, measured by the incidence of any serious RICE-related adverse events and decreased adverse events during hospitalization. The secondary outcome is a favorable prognosis within 90 days (mRS score < 2), determined by improvements in the mRS score, NIHSS score, Barthel Index, walking ability after 90 days, and infarct volume after 12 ± 2 days. Conclusion: This study is a prospective randomized controlled trial to determine the rehabilitative effect of early RIC followed by exercise on patients with acute ischemic stroke.

Abstract
The management of post-stroke complications plays an important role in the quality of life. Di-Tan Decoction (DTD; ) is a widely used traditional Chinese medicine. This study incorporated systematic review and meta-analysis to evaluate the efficacy of DTD in post-stroke neurological disorders. Randomized clinical trials (RCTs) were searched from English, Chinese and Korean electronic medical databases, by including the keywords "Di-Tan Tang", "Di-Tan Decoction", "Scour Phlegm Decoction", "stroke", and "RCT. Each RCT included control (placebo, conventional therapy, or Western medicine) and experimental (DTD treatment) groups. For patients inflicted with stroke for 1-6 weeks, the outcomes of post-stroke neurological disorders were measured by scales for post-stroke symptoms and were classified as "completely healed", "markedly effective", "effective" and "ineffective". Totally, 11 RCTs (n = 490 controls and n = 502 DTD subjects) were selected from 210 articles identified in the initial search. A meta-analysis of evaluation criteria in post-stroke symptoms revealed that the overall odds ratio (ORs) for alleviating post-stroke neurological disorders were 0.30-fold lower (95% CI = 0.21-0.43) in the DTD group than the control (Western medicine) group (P < 0.000 01). Moreover, regardless of the type of stroke diagnostic scale applied (including NFA, HDS, and NIHSS), the overall post-stroke symptoms determined were less severe in the DTD group (n = 219) than the control group (n = 217). No adverse effects of DTD were observed in the 11 RCTs reviewed. All 11 studies used an appropriate method for randomization of subjects to evaluate the risk of bias (ROB), and 7 studies included allocation concealment as well as blinding of patients and practitioners. High-risk ROB was included in 6 RCTs. No significant publication bias was derived from the funnel plot. Our results indicate that the administration of DTD alone, and DTD in combination with Western medicine, exert greater efficacy for post-stroke complication therapy, than Western medicine administered alone. More rigorous and regulated studies are required to confirm the therapeutic efficacy of DTD for post-stroke neurological disorders. disorders.

Abstract
Objective Our goal was to evaluate the efficacy of muscle spasm before and after rehabilitation by comparing shear wave propagation velocity (SWV) and Young's modulus (YM) in the normal and spastic biceps brachii in stroke patients. Methods A study of 60 stroke patients with upper limb spasm was performed; these patients were admitted from April 2018 to September 2019. The modified Ashworth scale (MAS) scores of the spastic biceps brachii before and after rehabilitation treatment were compared. SWV and YM on the spastic and normal biceps brachii before rehabilitation treatment, SWV and YM on the spastic and normal biceps brachii after rehabilitation treatment, and SWV and YM on the spastic biceps brachii before and after rehabilitation treatment were compared. Whether SWV and YM on the spastic biceps brachii are related to MAS was compared. Results There was a statistically significant difference in SWV and YM between the normal and spastic biceps brachii before (P < 0.01) and after (P < 0.05) the rehabilitation treatment. There was no statistically significant difference in SWV and YM in the normal biceps brachii before and after the rehabilitation treatment (P > 0.05). There was a statistically significant difference in SWV and YM in the spastic biceps brachii before and after the rehabilitation treatment (P < 0.01). SWV and FM of the spastic biceps brachii are correlated with MAS before and after rehabilitation treatment, and the correlation coefficient for SWV was 0.563 and 0.605 for YM (P < 0.05). Conclusion SWE can be used as a means of assessment before and after rehabilitation treatment.

METHODS Control group (CG) performed conventional physiotherapy twice a day and the intervention group (IG) performed a conventional physiotherapy and a cycle ergometer session, for five consecutive days. Subjects were assessed for muscle strength by a digital dynamometer, gait speed by the 10-meter-walk-test, balance by the Berg Balance Scale, mobility by the ICU-Mobility-Scale and functionality by the Perme Score. RESULTS Twenty subjects were enrolled in the study, 10 in the CG and 10 in the IG. Lower limbs muscle strength, the main endpoint, was better in the IG compared to the CG. The same was found in the secondary endpoints. The intragroup analysis was also positive for the CG in the mobility and functionality. CONCLUSIONS Conventional physiotherapy combined with cycling exercise showed better results in the improvement of muscle strength of lower limbs, mobility and functionality of subjects who suffered from acute stroke.

Abstract
Background: The efficacy of endoscopic surgery for spontaneous intracerebral hemorrhages (ICH) has been previously reported, but differences in the effect between early and late elderlies remain unclear. Methods: Ninety-seven patients diagnosed with putaminal hemorrhage (age, ≥65 years; hematoma volume, ≥30 mL) were included in this retrospective analysis and separated into three treatment groups: craniotomy surgery (CR), endoscopic surgery (EN), and non-surgical (NS) groups. The patients were additionally subdivided into two groups according to age: patients aged 65–74 years (“early elderlies”) and patients aged ≥75 years (“late elderlies”). Their clinical data and outcomes at discharge were compared using statistical analyses. Results: The CR and the EN groups were associated with lower mortality rates (P < 0.001), lower modified Rankin Scale (mRS; P = 0.007), and lower National Institutes of Health Stroke Scale (NIHSS; P = 0.029) compared to the NS group. Early elderlies in the CR and EN groups with ICH scores of 3 also had significantly better outcomes (P = 0.001). The proportion of patients with mRS ≤ 4 was highest in the early elderlies of the EN group (P = 0.553). Although significant differences in the change of NIHSS scores between the early and late elderlies was not observed, significantly improved NIHSS scores were observed in the EN group compared to the NS group, even in the late elderlies (P = 0.037). Conclusion: The evacuation of deep-seated intracranial hematomas using the endoscope might improve functional outcomes and mortality, regardless of age.

Abstract
Purpose The purpose of this study was to investigate the effectiveness of verbal-gestural treatment on verb production in patients with acute aphasia. Method Treatment was delivered during inpatient stay to four participants using a single-subject design. Results All patients demonstrated improvements in verbal expression. Some patients' improvements generalized to untrained verbs and nouns. Conclusions This study indicates verbal-gestural treatment can be an effective treatment model for acute aphasia in a hospital environment. Concurrent deficits resulting from stroke may impact the success with verbal-gestural treatment at this acute phase of recovery.

Abstract
Recent advances in the field of neural rehabilitation, facilitated through technological innovation and improved neurophysiological knowledge of impaired motor control, have opened up new research directions. Such advances increase the relevance of existing interventions, as well as allow novel methodologies and technological synergies. New approaches attempt to partially overcome long-term disability caused by spinal cord injury, using either invasive bridging technologies or noninvasive human-machine interfaces. Muscular dystrophies benefit from electromyography and novel sensors that shed light on underlying neuromotor mechanisms in people with Duchenne. Novel wearable robotics devices are being tailored to specific patient populations, such as traumatic brain injury, stroke, and amputated individuals. In addition, developments in robot-assisted rehabilitation may enhance motor learning and generate movement repetitions by decoding the brain activity of patients during therapy. This is further facilitated by artificial intelligence algorithms coupled with faster electronics. The practical impact of integrating such technologies with neural rehabilitation treatment can be substantial. They can potentially empower nontechnically trained individuals-namely, family members and professional carers-to alter the programming of neural rehabilitation robotic setups, to actively get involved and intervene promptly at the point of care. This narrative review considers existing and emerging neural rehabilitation technologies through the perspective of replacing or restoring functions, enhancing, or improving natural neural output, as well as promoting or recruiting dormant neuroplasticity. Upon conclusion, we discuss the future directions for neural rehabilitation research, diagnosis, and treatment based on the discussed technologies and their major roadblocks. This future may eventually become possible through technological evolution and convergence of mutually beneficial technologies to create hybrid solutions.

Abstract
Neurorehabilitation aspires to restore a person to his or her fullest potential after incurring neurological dysfunction. In medical rehabilitation, diagnosis involves assessment of medical conditions and their effects on functioning. It is usually a team effort that involves an amalgam of diagnostic assessments by multiple disciplines, leading to a collection of rehabilitative treatment plans and goals. This article discusses a clinical neurological paradigm, using rigorous clinical assessment of neuropathological and clinical diagnosis, along with prognostication of natural history and recovery. In the context of the role of neuroplasticity in recovery, this paradigm can add significant value to rehabilitation team management and planning. It contributes to enhanced understanding of neurological impairments and syndromes as they relate to functional disability, aiding in targeting deficits and setting treatment goals. Rehabilitation strategies and goals should be informed by natural history and prognosis, and viewed in the framework of the stage of recovery. Prognostic formulations should suggest an emphasis on restorative versus compensatory strategies for functional problems. Treatment planning should be informed by evidence on how interventions modulate brain reorganization in promoting recovery. Strategies that promote adaptive neuroplasticity should be favored, especially with restorative efforts, and evidence supporting optimal techniques, timing, and dosing of rehabilitation should be considered in treatment planning.

Abstract
BACKGROUND Robotic systems combined with Functional Electrical Stimulation (FES) showed promising results on upper-limb motor recovery after stroke, but adequately-sized randomized controlled trials (RCTs) are still missing. OBJECTIVE To evaluate whether arm training supported by RETRAINER, a passive exoskeleton integrated with electromyograph-triggered functional electrical stimulation, is superior to advanced conventional therapy (ACT) of equal intensity in the recovery of arm functions, dexterity, strength, activities of daily living, and quality of life after stroke. METHODS A single-blind RCT recruiting 72 patients was conducted. Patients, randomly allocated to 2 groups, were trained for 9 weeks, 3 times per week: the experimental group performed task-oriented exercises assisted by RETRAINER for 30 minutes plus ACT (60 minutes), whereas the control group performed only ACT (90 minutes). Patients were assessed before, soon after, and 1 month after the end of the intervention. Outcome measures were as follows: Action Research Arm Test (ARAT), Motricity Index, Motor Activity Log, Box and Blocks Test (BBT), Stroke Specific Quality of Life Scale (SSQoL), and Muscle Research Council. RESULTS All outcomes but SSQoL significantly improved over time in both groups (P < .001); a significant interaction effect in favor of the experimental group was found for ARAT and BBT. ARAT showed a between-group change of 11.5 points (P = .010) at the end of the intervention, which increased to 13.6 points 1 month after. Patients considered RETRAINER moderately usable (System Usability Score of 61.5 ± 22.8). CONCLUSIONS Hybrid robotic systems, allowing to perform personalized, intensive, and task-oriented training, with an enriched sensory feedback, was superior to ACT in improving arm functions and dexterity after stroke.

Abstract
There is no consensus about the definition or most effective treatment for neglect syndrome. The aim of this review was therefore to evaluate the results of trials that investigated different treatment methods for neglect syndrome. A systematic literature search in PubMed and Web of Science databases was performed to identify studies that investigated the effects of neglect therapies. Authors followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Studies were selected by two assayers, and disagreement was resolved by a third reviewer. The literature search identified 202 articles: 19 met the inclusion criteria and were included for data extraction. Thirty-five different kinds of assessments were used in these studies, and 17 treatment methods were applied. Successful treatments were reported at least in some parts of the assessments in 12 studies: mirror therapy (in two trials), transcranial magnetic stimulation, street crossing test in virtual reality, smooth pursuit eye movement training, saccadic eye movement therapy, direct current stimulation, eye patching therapy, prism adaptation treatment, socially assistive pet-type therapeutic robot (PARO), Kinesiological Instrument for Normal and Altered Reaching Movement robotic device therapy, transcutaneous electrical nerve stimulation, and optokinetic stimulation (the last two methods in the same trial). No success was shown in seven trials, which contained not only single treatments but combined ones also. Authors concluded that there are no convincing results for or against any of the different therapies used for neglect syndrome. The quality of the trials is questionable, and the numbers of included patients are small in the trials.

Abstract
BACKGROUND We performed a randomized clinical trial protocol to assess the effectiveness of edaravone for acute stroke. We hypothesized that edaravone is beneficial in improving neurological impairment resulting from acute stroke. METHOD The protocol was reviewed and approved by the Research Ethics Board of Affiliated Hospital of Chengde Medical University (0092-2394), each participant signed a written consent before participating, and SPIRIT guidelines were followed throughout. The inclusion criteria for patients were as follows: diagnosed as acute stroke (ischemic stroke or intracerebral hemorrhage) by head CT or MRI within 72 hours; age greater than 18; motor function disorder; Glasgow Coma Scale greater than 12. Patients with the following symptoms were excluded: concurrent serious complications, such as coma, drug allergy, mental disorder, and other severe organic lesions in the brain. Sixty patients were finally included in the study. The control group accepted conventional treatment, while the treatment group received edaravone treatment on top of the conventional treatment of the control group. After treatment, the differences in functional movement, living ability score, neurological score, treatment effect, and adverse reaction of these 2 groups were tested and compared. DISCUSSION As aging worsens, the incidence of acute stroke continues to increase. Brain damage will induce the production of oxygen radicals, which can damage the cytomembrane of brain cells and finally damage the nervous system and cause cerebral injury as well as the cerebral edema. Edaravone is an antioxidant and oxygen radical scavenger that can inhibit lipid peroxidation during the scavenging of oxygen free radicals. Besides, it can also elicit anti-inflammatory protective effects for nerve cells, increase cerebral blood flow volume, prevent the aggravation of cerebral hypoperfusion toward necrosis, reduce nerve damage, and improve neurological functions and prognosis. This is the first randomized controlled trial to assess the efficacy of edaravone for treating acute stroke. High quality, large sample size, multicenter randomized trials are still required.

Effect of Tetramethylpyrazine on Neuroplasticity after Transient Focal Cerebral Ischemia Reperfusion in Rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:1587241.

Abstract
Tetramethylpyrazine (TMP) has been widely used in ischemic stroke in China. The regulation of neuroplasticity may underlie the recovery of some neurological functions in ischemic stroke. Middle cerebral artery occlusion (MCAO) model was established in this study. Rats were divided into three groups: sham group, model group, and TMP group. The neurological function was evaluated using modified neurological severity score (mNSS). Following the neurological function test, expression of synaptophysin (SYP) and growth-associated protein 43 (GAP-43) were analyzed through immunohistochemistry at 3 d, 7 d, 14 d, and 28 d after MCAO. Finally, the synaptic structural plasticity was investigated using transmission electron microscopy (TEM). The TMP group showed better neurological function comparing to the model group. SYP levels increased gradually in ischemic penumbra (IP) in the model group and could be enhanced by TMP treatment at 7 d, 14 d, and 28 d, whereas GAP-43 levels increased from 3 d to 7 d and thereafter decreased gradually from 14 d to 28 d in the model group, which showed no significant improvement in the TMP group. The results of TEM showed a flatter synaptic interface, a thinner postsynaptic density (PSD), and a wider synaptic cleft in the model group, and the first two alterations could be ameliorated by TMP. Then, a Pearson's correlation test revealed mNSS markedly correlated with SYP and synaptic ultrastructures. Taken together, TMP is capable of promoting functional outcome after ischemic stroke, and the mechanisms may be partially associated with regulation of neuroplasticity.

Abstract
OBJECTIVES Hospitalised patients are at risk of temporary or permanent loss of functioning which impacts their future independence. Implementation of a rehabilitative approach in everyday nursing in the acute care setting may produce good therapeutic results and promote independent daily living of patients. Thus, the aim of the study was to explore and understand the patterns of a rehabilitative approach in acute hospital wards from the perspective of interdisciplinary team members. Specifically, our aim was to identify the factors promoting and preventing a rehabilitative approach. METHOD We conducted four focus group interviews with 21 participants, including multidisciplinary team members from acute hospital wards. Data were analysed with conventional inductive content analysis. RESULTS The findings highlighted that the rehabilitative approach, as a personal way of working and personal working attitude, was a part of comprehensive nursing. The main goals of the rehabilitative approach were to support the physical functioning of the patients and their independent initiative and individuality during clinical care in hospital ward. The promoting and preventing factors that influenced the development of the rehabilitative approach consisted of personal factors, organisational factors and the physical settings of the hospital wards. CONCLUSION The findings of this study indicate that the rehabilitative approach in nursing focused on supporting the physical functioning, independence and self-confidence of the patient. The staff highlighted that interdisciplinary teamwork was one feature of the rehabilitative approach. The rehabilitative approach in nursing should be established as a part of everyday activity in clinical practice.

Abstract
A growing body of evidence has suggested that the imbalance of epigenetic markers and oxidative stress appears to be involved in the pathophysiology and progression of stroke. Thus, strategies that modulate these biomarkers might be considered targets for neuroprotection and novel therapeutic opportunities for these patients. Physical exercise has been reported to induce changes in these epigenetic markers and improve clinical outcomes in different populations. However, little is reported on this in post-stroke patients. The purpose of this study was to investigate the effect of a single exercise session with WalkAide functional electrical stimulation (FES) on cognitive performance, clinical functional parameters, oxidative stress and epigenetic modulation in post-stroke individuals. In this crossover design study, 12 post-stroke individuals aged 54–72 years of either sexes were included and subjected to a single session of exercise (45 minutes) without WalkAide functional electrical stimulation (EXE alone group), followed by another single session of exercise (45 minutes) with WalkAide functional electrical stimulation (EXE + FES group). The clinical functional outcome measures, cognitive performance and blood collections for biomarker measurements were assessed pre- and post-intervention. After intervention, higher Berg Balance Scale scores were obtained in the EXE + FES group than in the EXE alone group. There was no significant difference in the Timed Up and Go test results post-intervention between EXE alone and EXE + FES groups. After intervention, a better cognitive performance was found in both groups compared with before the intervention. After intervention, the Timed Up and Go test scores were higher in the EXE + FES group than in the EXE alone group. In addition, the intervention induced lower levels of lipid peroxidation. After intervention, carbonyl level was lower, superoxide dismutase activity and superoxide dismutase/catalase activity ratio were higher in the EXE + FES group, compared with the EXE group alone. In each group, both histone deacetylase (HDAC2) and histone acetyltransferase activities were increased after intervention compared with before the intervention. These findings suggest that a single exercise session with WalkAide FES is more effective on balance ability and cognitive performance compared with conventional exercise alone in post-stroke patients. This is likely to be related to the regulation of oxidative stress markers. The present study was approved by the Research Ethics Committee of the Methodist University Center-IPA (approval No. 2.423.376) on December 7, 2017 and registered in the Brazilian Registry of Clinical Trials—ReBEC (RBR-9phj2q) on February 11, 2019.

Abstract
QUESTION Independent practice via an application with a language exercise program for aphasia, as an add-on to conventional care can be a good solution to intensify aphasia therapy. The aim of this prospective trial was to investigate the feasibility, usability and acceptability of the newly-developed aphasia exercise program in the 'Speech Therapy App (STAPP)' in the acute phase post-stroke. METHODS All eligible people with aphasia following stroke (<2 weeks post-stroke) admitted to the Stroke Unit of Ghent University Hospital were recruited in this prospective clinical trial between September 2018 and December 2019. After linguistic assessments and two short training sessions, participants were asked to practice independently with 'STAPP' for at least 30 min/day during hospitalization. Exercises were individually tailored and adjusted if necessary. Outcome was measured by recruitment, adherence and retention rates, usability questionnaires and a visual analogue scale for satisfaction. RESULTS Twenty-five (mean age 65 years (SD = 17), 14 females) of 31 eligible people with aphasia were enrolled in this trial (recruitment rate = 81 %). All participants but one (23/24) practiced with the language app until the end of hospitalization (retention rate = 96 %). Ten participants practiced at least 30 min/day (adherence rate = 42 %). Participants reported they learned to work quickly with the app (92 %; agreed/totally agreed), the app was easy to use (88 %), they could work independently (79 %), practiced their language (67 %) and wanted to continue working with the app at home (79 %). Acceptability was high (median satisfaction rate 91 %; IQR = 75-100). CONCLUSION The aphasia exercise program in 'STAPP' is feasible to use as an additional rehabilitation tool along with standard of care in the acute phase post-stroke. Further research is needed to assess the efficacy. CLINICAL TRIAL REGISTRATION-URL: https://clinicaltrials.gov/ct2/show/NCT03679637.

Introduction. r-TPA intravenous thrombolytic therapy is a big step in acute management of ischemic stroke (IS) but is burdened by a small therapeutic window (max. 4.5 hours) that restricts patient access. NIH stroke scale (NIHSS) is the largest worldwide tool used by doctors in order to objectively quantify the severity of neurological impairment in acute IS, in the initial stage as well as in the subsequent stages. Material and method. The aim of this paper is to present the results of an observational, prospective, analytical study on a number of 110 patients with acute IS, hospitalized within two months in the Neurology Clinic of Sibiu (19 patients with thrombolytic therapy applied, 91 patients with classic therapy). NIHSS has been applied to all patients on the first day of the admission and at the discharge date. Results and discussions. The mean value of NIHSS at admission and at discharge (A/D) were 12,84/4.06 points for the patient with thrombolytic therapy and 7,73/4,45 points for the patients without thrombolytic therapy. In hospital NIHSS score reduction, meaning early recovery of patients, was consistent with type of applied therapy (8.78 vs3.28 points). The pattern of neurological impairment is specific for each subtype of IS. Conclusions. The degree of early recovery was superior for patients with versus without thrombolytic therapy (68.4% versus 42.4%). Average hospital care period was reduced with 8,33% for patients with thrombolytic therapy (11,4 versus 12,2 days care in hospital).

Cost and cost-effectiveness of early inpatient rehabilitation after stroke varies with initial disability: the Czech Republic perspective. Int J Rehabil Res 2020; 43:376-382. [PMID: 32991353 PMCID: PMC7643793 DOI: 10.1097/mrr.0000000000000440] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Accepted: 09/01/2020] [Indexed: 11/25/2022]
Abstract
The purpose of this prospective study was to determine whether the cost and cost-effectiveness of early rehabilitation after stroke are associated with the degree of initial disability. The data for cost calculations were collected by the bottom-up (micro-costing) method alongside the standard inpatient care. The total sample included 87 patients who were transferred from acute care to early rehabilitation unit of three participating stroke centers at the median time poststroke of 11 days (range 4-69 days). The study was pragmatic so that all hospitals followed their standard therapeutic procedures. For each patient, the staff recorded each procedure and the associated time over the hospital stay. The cost and cost-effectiveness were compared between four disability categories. The average cost of the entire hospitalization was CZK 114 489 (EUR 4348) with the daily average of CZK 5103 (EUR 194). The cost was 2.4 times higher for the immobile category (CZK/EU: 167 530/6363) than the self-sufficient category (CZK/EUR: 68 825/2614), and the main driver of the increase was the cost of nursing. The motor status had a much greater influence than cognitive status. We conclude that the cost and cost-effectiveness of early rehabilitation after stroke are positively associated with the degree of the motor but not cognitive disability. To justify the cost of rehabilitation and monitor its effectiveness, it is recommended to systematically record the elements of care provided and perform functional assessments on admission and discharge.

Abstract
Background Although many studies have demonstrated the effectiveness of transcranial direct current stimulation (tDCS) in improving speech recovery in post-stroke aphasia, as far as we know patients affected by thalamic aphasia have never been investigated. Patient and method A 65-year-old man with severe non-fluent aphasia due to a left thalamic haemorrhagic stroke underwent intensive daily speech therapy combined with tDCS. Results The patient showed progressive improvement with almost complete recovery of his speech disorder, behavioural disinhibition and apathy. Conclusions Our findings suggest that tDCS with concurrent speech therapy can be useful in patients with subcortical stroke lesions. LEARNING POINTS The thalamus has a central role in the development of the higher functions, such as memory, regulation of behaviour and emotions, and language elaboration.Transcranial direct current stimulation (tDCS) applied to the cerebral cortex is a promising tool for improving language recovery in patients with post-stroke aphasia.Combined treatment with tDCS and speech and language therapy (SLT) was effective in a patient with subacute thalamic aphasia, who showed improvement in all aspects of linguistic and behavioural communication.

Abstract
PURPOSE OF REVIEW We explored themes in recent post-stroke dysphagia literature, focusing on the following questions: (1) What does post-stroke dysphagia look like?; (2) Who gets post-stroke dysphagia?; (3) What are the consequences of post-stroke dysphagia?; and (4) How can we improve treatment of post-stroke dysphagia? RECENT FINDINGS There have been several improvements in quantitative descriptions of swallowing physiology using standard and new evaluation techniques. These descriptions have been correlated with lesion locations, and several factors can predict development of post-stroke dysphagia and its sequelae. Novel treatment paradigms have leveraged post-stroke neuroplastic improvements using neurostimulation and biofeedback techniques. Despite recent findings, the field is limited by lack of standardization and unanswered questions on rehabilitation variables. Our improved understanding of post-stroke dysphagia will enhance our ability to prevent, identify, and treat it. Future work should be grounded in swallowing physiology and continue refining treatments, particularly in the acute stage.

Abstract
The aim of the study is to investigate how time and uncertainties of clinical action and decision-making plays out in the practical work of early neurorehabilitation in order to present new analytical ways to understand the underlying logics and dynamic social processes that take place during professional treatment of patients with severe acquired brain injury. Drawing on ethnographic fieldwork in a Danish neuro-intensive step-down unit (NISU) specialising in early neurorehabilitation, we found that negotiation of futures takes place in the modern ICU in the present by strategically building upon past experiences. We have argued that the clinical programme therefore cannot be understood only from a "here and now perspective", since the early neurorehabilitation practice is embedded in overlapping temporalities of the past, the present, and desired futures. The study discusses the underlying logics-often hidden or unnoticed-that impact clinical practice of early neurorehabilitation, in what we have termed a logic of clinical reenactment, a logic of future negotiation and a logic of paradox.

Abstract
Abstract
Hemiparesis after stroke is associated with increased neural activity not only in the lesioned but also in the contralesional hemisphere. While most studies have focused on the role of contralesional primary motor cortex (M1) activity for motor performance, data on other areas within the unaffected hemisphere are scarce, especially early after stroke. We here combined functional magnetic resonance imaging (fMRI) and transcranial magnetic stimulation (TMS) to elucidate the contribution of contralesional M1, dorsal premotor cortex (dPMC), and anterior intraparietal sulcus (aIPS) for the stroke-affected hand within the first 10 days after stroke. We used “online” TMS to interfere with neural activity at subject-specific fMRI coordinates while recording 3D movement kinematics. Interfering with aIPS activity improved tapping performance in patients, but not healthy controls, suggesting a maladaptive role of this region early poststroke. Analyzing effective connectivity parameters using a Lasso prediction model revealed that behavioral TMS effects were predicted by the coupling of the stimulated aIPS with dPMC and ipsilesional M1. In conclusion, we found a strong link between patterns of frontoparietal connectivity and TMS effects, indicating a detrimental influence of the contralesional aIPS on motor performance early after stroke.

Abstract
Background Individuals with acquired brain injuries (ABI) are in need of neurorehabilitation and neurorepair. Virtual anatomical interactivity (VAI) presents a digital game-like format in which ABI survivors with upper limb paresis use an unaffected limb to control a standard input device and a commonplace computer mouse to control virtual limb movements and tasks in a virtual world. Methods In a prospective cohort study, 35 ambulatory survivors of ABI (25/71% stroke, 10/29% traumatic brain injury) were enrolled. The subjects were divided into three groups: group A received VAI therapy only, group B received VAI and physical/occupational therapy (P/OT), and group C received P/OT only. Motor skills were evaluated by muscle strength (hand key pinch strength, grasp, and three-jaw chuck pinch) and active range of motion (AROM) of the shoulder, elbow, and wrist. Changes were analyzed by ANOVA, ANCOVA, and one-tailed Pearson correlation analysis. MRI data was acquired for group A, and volumetric changes in grey matter were analyzed using voxel-based morphometry (VBM) and correlated with quantified motor skills. Results AROM of the shoulder, elbow, and wrist improved in all three groups. VBM revealed grey matter increases in five brain areas: the tail of the hippocampus, the left caudate, the rostral cingulate zone, the depth of the central sulcus, and the visual cortex. A positive correlation between the grey matter volumes in three cortical regions (motor and premotor and supplementary motor areas) and motor test results (power and AROM) was detected. Conclusions Our findings suggest that the VAI rehabilitation program significantly improved motor function and skills in the affected upper extremities of subjects with acquired brain injuries. Significant increases in grey matter volume in the motor and premotor regions of affected hemisphere and correlations of motor skills and volume in nonaffected brain regions were present, suggesting marked changes in structural brain plasticity. Trial registration The trial “Limitations of motor brain activity – use of virtual reality for simulation of therapeutic interventions” has been registered under reference number ISRCTN11757651.

Novel TMS for Stroke and Depression (NoTSAD): Accelerated Repetitive Transcranial Magnetic Stimulation as a Safe and Effective Treatment for Post-stroke Depression. Front Neurol 2020; 11:788.

Abstract
Background: Post-stroke depression (PSD) affects up to 50% of stroke survivors, reducing quality of life, and increasing adverse outcomes. Conventional therapies to treat PSD may not be effective for some patients. Repetitive transcranial magnetic stimulation (rTMS) is well-established as an effective treatment for Major Depressive Disorder (MDD) and some small trials have shown that rTMS may be effective for chronic PSD; however, no trials have evaluated an accelerated rTMS protocol in a subacute stroke population. We hypothesized that an accelerated rTMS protocol will be a safe and viable option to treat PSD symptoms. Methods: Patients (N = 6) with radiographic evidence of ischemic stroke within the last 2 weeks to 6 months with Hamilton Depression Rating Scale (HAMD-17) scores >7 were recruited for an open label study using an accelerated rTMS protocol as follows: High-frequency (20-Hz) rTMS at 110% resting motor threshold (RMT) was applied to the left dorsolateral prefrontal cortex (DLPFC) during five sessions per day over four consecutive days for a total of 20 sessions. Safety assessment and adverse events were documented based on the patients' responses following each day of stimulation. Before and after the 4-days neurostimulation protocol, outcome measures were obtained for the HAMD, modified Rankin Scale (mRS), functional independence measures (FIM), and National Institutes of Health Stroke Scales (NIHSS). These same measures were obtained at 3-months follow up. Results: HAMD significantly decreased (Wilcoxon p = 0.03) from M = 15.5 (2.81)-4.17 (0.98) following rTMS, a difference which persisted at the 3-months follow-up (p = 0.03). No statistically significant difference in FIM, mRS, or NIHSS were observed. No significant adverse events related to the treatment were observed and patients tolerated the stimulation protocol well overall. Conclusions: This pilot study indicates that an accelerated rTMS protocol is a safe and viable option, and may be an effective alternative or adjunctive therapy for patients suffering from PSD. Future randomized, controlled studies are needed to confirm these preliminary findings. Clinical Trial Registration: https://clinicaltrials.gov/ct2/show/NCT04093843.

Abstract
Background: The purpose of this paper is to narratively review the literature on caring for stroke patients with a musculoskeletal problem which involves rehabilitation of nursing and health care. Through the review, this paper addresses five questions: What are the typical difficulties of a stroke patient? What are the effects of a stroke on the musculoskeletal system? How to take care of musculoskeletal problem and pain? What is good musculoskeletal care for patients with stroke? How to take care of the musculoskeletal problem through active rehabilitation? Method: The relevant articles published between 2010-2020 were identified through searches in PubMed, Google Scholar, CINAHL, PsychInfo and by inspecting the reference list using keywords of ‘stroke’ and ‘musculoskeletal’. Result: A total of 19 selected address this topic and consequently answer the questions posed. Findings flow with the typical difficulties of a stroke patient, the effects of a stroke on the musculoskeletal system, caring for musculoskeletal problem and pain, good musculoskeletal care for patients with stroke and caring for the musculoskeletal problem through active rehabilitation. Conclusion: This paper highlights that stroke patients with the musculoskeletal problem have restricted day-to-day movement functions and needed interdisciplinary care approaches from nursing, physical and occupational therapies, and other health care professionals. Stroke patients may need a structured programme to improve the outcome of stroke rehabilitation for the musculoskeletal problem.

What Determines Good Rehabilitation Recovery in Stroke Patients with very Severe Disability? A Retrospective Cohort Study. J Stroke Cerebrovasc Dis 2020; 29:105130. [PMID: 32912513 DOI: 10.1016/j.jstrokecerebrovasdis.2020.105130] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Revised: 07/01/2020] [Accepted: 07/02/2020] [Indexed: 02/07/2023] Open
Abstract
OBJECTIVE This study aimed to evaluate predictors of good recovery after rehabilitation in stroke patients with very severe disability. METHODS 168 Eligible patients were enrolled. Fugl-Meyer of motor score (FMM), National Institute of Health Stroke Scale (NIHSS), and Modified Barthel Index (MBI) were used to measure the motor and degree of disability. Logistic regressions were used to investigate the effect of 21 pre-existing conditions on efficacy outcomes after 4 weeks rehabilitation. RESULTS The results indicated the following: 1) FMM (r = 0.2, P=0.02) and NIHSS (r = -0.2, P=0.00) were significantly correlated (positively and negatively, respectively) with fat-free mass index (FFMI); 2)FFMI (odds ratio [OR],1.9; 95% CI, 1.1 to 3.3; P=0.02), OAI (OR, 0.9; 95% CI, 0.9 to 1.0; P=0.00), and FMM (OR, 1.0; 95% CI, 1.0 to 1.1; P=0.00) were revealed as predictors of good recovery after 4 weeks rehabilitation; 3) The model could predict the possibility of good recovery in stroke patients with very severe disability with excellent sensitivity and specificity(80.0% and 67.1%, respectively). CONCLUSIONS The results could enable clinicians to predict good recovery after rehabilitation in patients with very severe post-stroke disability.

Effect of Post-Stroke Rehabilitation on Body Mass Composition in Relation to Socio-Demographic and Clinical Factors. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17145134. [PMID: 32708623 PMCID: PMC7400096 DOI: 10.3390/ijerph17145134] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Revised: 07/09/2020] [Accepted: 07/14/2020] [Indexed: 12/15/2022]
Abstract
Background and objectives: Stroke is one of the leading causes of morbidity, mortality and long-term adult disability. The aim of this study was to assess the changes in body mass composition in patients after stroke in connection with selected socio-demographic and clinical factors (sex, age, type of stroke and time from the first symptoms) following the rehabilitation process. Materials and Methods: The study group consisted of 100 post-stroke subjects who participated in a comprehensive rehabilitation program for a duration of five weeks. The measurements of body composition by a Tanita MC 780 MA analyser were performed on the day of admission to hospital, on the day of discharge (after 5 weeks) and 12 weeks after discharge from hospital. Results: It was shown that before rehabilitation (Exam I) in the study group there were significant differences in body composition relative to sex, age and time from stroke. The rates of fat mass % and visceral fat level decreased after rehabilitation (Exam II) in both males and females. Exam II, at the end hospital rehabilitation, showed lower levels of fat mass %, visceral fat level, as well as fat-free mass % and higher values of total body water % and muscle mass %. In Exam III, i.e., 12 weeks after discharge, all of the parameters retained their values. Conclusions: The study shows an association between stroke risk factors (primarily age, sex and time from the onset of the first symptoms of stroke) and body mass composition resulting from rehabilitation. The type of stroke and the effects of rehabilitation on body mass components showed no differences. Comprehensive rehabilitation had a positive effect on the body mass components.

Virtual reality (VR)-based interventions are gaining widespread attention for managing neurological disorders such as stroke. A metastatistical consensus regarding the intervention is strongly warranted. In this study, we attempt to address this gap in the literature and provide the current state of evidence for the effects of VR on gait performance. We conducted both between- and within-group meta-analyses to provide a state of evidence for VR. Moreover, we conducted a search adhering to PRISMA guidelines on nine databases. Out of 1866 records, 32 studies involving a total of 809 individuals were included in this review. Considering all included studies, significant enhancements in gait parameters were observed with VR-based interventions compared with conventional therapy. A between-group meta-analysis reported beneficial significant medium effects of VR training on cadence (Hedge's g = 0.55), stride length ((STrL; Hedge's g = 0.46), and gait speed (Hedge's g = 0.30). Similarly, a within-group meta-analysis further revealed positive medium effects of VR on cadence (Hedge's g = 0.76), STrL (Hedge's g = 0.61), and gait speed (Hedge's g = 0.69). Additional subgroup analyses revealed beneficial effects of joint application of VR and robot-assisted gait training on gait speed (Hedge's g = 0.50). Collectively, findings from this review provide evidence for the effectiveness of VR-based gait training for stroke survivors.

Abstract
Coronavirus disease 2019 (COVID-19) is a pandemic respiratory disease with serious public health risk and has taken the world off-guard with its rapid spread. As the COVID-19 pandemic intensifies, overwhelming the healthcare system and the medical community, current practice for the management of acute ischemic stroke (AIS) will require modification, and guidelines should be relaxed while maintaining high standard quality of care. The aim of these suggestions is to avoid contributing to the rapid spread of COVID-19 as well as to conserve what are likely to be very limited resources (including personnel, intensive care/hospital beds as well as physicians) while maintaining high quality care for patients with AIS. We present our recommendations for the management of acute stroke during the COVID-19 pandemics.

Abstract
INTRODUCTION Stroke is a complex event on both behavioral and neuronal grounds. Recent investigations evidence the central role of subcortical damage on the post-stroke brain and behavior reorganization. We have conducted an exploratory study combining anatomical lesion analysis, functional analysis of resting state fMRI, and behavioral assessment with focus on exploration as represented by SEEKING. METHOD 24 stroke inpatients were studied immediately after their clinical stabilization post-stroke; neuronal variability in fMRI along with behavioral outcomes were assessed. These outcomes were compared with a control group of 22 healthy subjects. RESULTS First, we observed predominant subcortical lesions in our sample with all stroke patients showing subcortical lesions and only some exhibiting additional cortical lesions. Second, we observed significantly reduced neuronal variability in the posterior cingulate cortex (PCC) that did not show any structural damage. Third, our stroke subjects showed reduced SEEKING which was related to reduced PCC neuronal variability in an abnormal way (compared to healthy subjects). This last outcome was assessed by considering the subset of 11 stroke subjects for which fMRI and behavioral outcomes were jointly measured. CONCLUSIONS Taken together, our findings suggest that damage in subcortical regions may play a central role in abnormalities in both cortical activity (PCC) and associated behavior of post-stroke reorganization. Accounting for these aspects may have significant implications to optimize multidisciplinary rehabilitation processes, particularly during the early steps of recovery, reducing the impact of stroke on the patient and caregiver quality of life.
