Cognitive-motor interference in people with essential tremor

Adapting to different environments throughout daily activities requires flexibility in allocating attention. Compromised dual-tasking can hinder mobility, increase fall risk, and decrease functional independence in patients with essential tremor, who exhibit both mobility and cognitive impairments. We evaluated motor and cognitive dual-task effects and task prioritization in 15 people with Essential Tremor (ET) and 15 age-matched people without ET during a standard and more challenging water-carry TUG. Task-specific interference was evaluated by calculating motor and cognitive dual-task effects, whereas task prioritization was assessed by contrasting the cognitive dual-task effect with the motor dual-task effect. The simultaneous performance of two tasks did not differentially impact motor or cognitive performance in either group, and both groups prioritized cognitive task performance in standard and water-carry TUG assessments. This study enhances our understanding of motor-cognitive interactions in individuals with essential tremor. These insights could lead to patient-centered approaches to therapy to improve functional performance in dynamic daily environments.

Rehabilitation and functional outcomes of COVID-19 patients in a rehabilitation hospital in Qatar.

Patients recovering from severe COVID-19 infections have experienced prolonged cognitive, physical, and psychological sequelae, including cardiorespiratory and motor deconditioning, neurological deterioration, anxiety, and depression. The impact of rehabilitation post-acute COVID-19 infection was recognized in the literature, but studies assessing and quantifying specific functional outcomes were lacking. This study aims to describe the characteristics and quantify the changes in functional outcomes of patients admitted to Qatar Rehabilitation Institute (QRI) for inpatient rehabilitation (IPR) post-COVID-19 infection during a 10-month period in 2021. This is a retrospective observational cohort study, which included individuals over 18 years of age with a documented COVID-19-positive diagnosis who were admitted to QRI for IPR due to COVID-19 complications. Data was collected by the investigators from January 1, 2021, until October 30, 2021. A total of 243 patients were included in this study. The changes in functional rehabilitation outcomes were assessed and quantified at both the patient's baseline (on admission to QRI) and after completion of IPR (on discharge). The duration of the IPR program varied based on each patient's baseline assessment. Patients were given a total of 8-12 weeks to achieve their rehabilitation goals and were discharged once those goals were met. Several validated tools were utilized in this study including Functional Independence Measure (FIM), Berg Balance Scale (BBS), Dynamic Gait Index (DGI), Modified Medical Research Council (mMRC) Dyspnea Scale, Mini-Mental State Examination (MMSE), and Right- and left-Hand Grip Strength. In addition, patients' diet, the need for respiratory support, and the presence of a tracheostomy tube before and after IPR were also recorded. In total, 84.4% of the included patients were males (n = 205); with a mean age of 52.44 ± 12.99 years. The most commonly reported comorbidities were type 2 diabetes (62.1%) and hypertension (49.8%) with 83.5% of patients experiencing critical illness neuromyopathy. The average patients' length of stay in QRI was 33.92 ± 27.72 days. A statistically significant improvement in all functional outcome scales was noted following the completion of the IPR program (p = 0.001). The number of patients requiring modification to their diet or feeding via nasogastric tube (NGT) significantly decreased by 35% and 93%, respectively (p = 0.001). Patients requiring respiratory support decreased by 98% (p = 0.001) and the need for a tracheostomy tube among patients was reduced by 95% (p = 0.001). IPR following COVID-19 infection was associated with significant functional, motor, and cardiorespiratory improvement. Dedicating clinics for post-COVID-19 rehabilitation would ensure improved patient outcomes and enhanced recovery.

Beyond Conventional Imaging: A Systematic Review and Meta-Analysis Assessing the Impact of Computed Tomography Perfusion on Ischemic Stroke Outcomes in the Late-Window.

Non-contrast CT (NCCT) and CT angiogram (CTA) have become essential for endovascular treatment (EVT) in acute stroke. Patient selection may improve when CT perfusion imaging (CTP) is also added for patient selection. We aimed to analyze the effects of implementing CTP in acute ischemic stroke (AIS) patients' treatment to assess whether stroke outcomes differ in the late window. We searched the PubMed, Embase, and Web of Sciences databases to obtain articles related to CTA and CTP in EVT. Collected patient data was split into two groups: the CTP and control (NCCT+CTA) cohorts. Primary outcomes evaluated were modified Rankin Scale (mRS) scores, symptomatic intracranial hemorrhages (sICH), mortality, and successful recanalization. There were 14 studies with 5,809 total patients in the final analysis: 2,602 received CTP and 3,202 were in the control group. CTP/CTA patients showed significantly lower rates of 90-day stroke-related mortality (OR: 0.72, 95% CI 0.60-0.87, p<0.01) and significantly higher successful recanalization (OR: 1.42, 95% CI 1.06-1.94, p<0.01) compared to CTA-only patients. Analysis of other outcomes including functional independence (mRS 0-2), critical times, and intracranial hemorrhages were non-significant (p > 0.05). The study highlights the usefulness of CTP-guided therapy as a supplementary tool in EVT selection in the late window. Although the addition of CTP resulted in lower mortality, the favorable outcomes did not improve. Further evidence is required to establish a clearer understanding of the potential advantages or limitations of incorporating CTP in stroke imaging.

Determinants of low satisfaction with life among wheelchair users with spinal cord injury in Egypt: a cross-sectional study

BackgroundSpinal cord injury (SCI) is one of the most catastrophic injuries that might lead to permanent use of a wheelchair and severely affects the quality of life, hence SCI patients report lower satisfaction with life (SWL) than the general population. Therefore, it is important to identify factors that determine SWL among wheelchair users with SCI. Our study aimed to assess the prevalence of low SWL and to identify its determinants among wheelchair users with SCI in Egypt.MethodsA cross-sectional study included 105 wheelchair users with SCI from the Al Hassan Foundation for wheelchair users in Egypt. The main outcome measure was low SWL, while the independent variables included sociodemographic characteristics, injury-related characteristics, anxiety, depression, neuropathic pain, functional independence, and environmental barriers.ResultsThe prevalence of low SWL among study participants was 57.1%. We found significant associations between SWL and age, area of living, and age at injury. Additionally, SWL correlated negatively with anxiety, depression, neuropathic pain, and environmental barriers, and positively with functional independence. Finally, the binary multiple logistic regression revealed that living in Upper Egypt (p = 0.017, OR = 13.7), depression (p = 0.034, OR = 6.08), older age (p = 0.002, OR = 1.21), and work and school environmental barriers (p = 0.022, OR = 0.46) were the predictors of low SWL.ConclusionTo improve the SWL for wheelchair users with SCI we need to effectively manage neuropathic pain, depression, and anxiety, and promote functional independence. There is an urgent need to reinforce legislation to improve the living conditions for wheelchair users with SCI in Egypt, especially in Upper Egypt.

Cerebral blood flow from arterial spin labeling as an imaging biomarker of outcome after endovascular therapy for ischemic stroke.

Arterial spin labeling (ASL) is a contrast agent-free magnetic resonance imaging (MRI) technique to measure cerebral blood flow (CBF). We sought to investigate effects of CBF within the infarct on outcome and risk of hemorrhagic transformation (HT). In 111 patients (median age: 74 years, 50 men) who had undergone mechanical thrombectomy (MT) for ischemic stroke of the anterior circulation (median interval: 4 days between MT and MRI), post-stroke %CBF difference from pseudo-continuous ASL was calculated within the diffusion-weighted imaging (DWI)-positive infarct territory following lesion segmentation in relationship to the unaffected contralateral side. Functional independence was defined as a modified Rankin Scale (mRS) of 0-2 at 90 days post-stroke. %CBF difference, pre-stroke mRS, and infarct volume were independently associated with functional independence in a multivariate regression model. %CBF difference was comparable between patients with and without HT. A subcohort of 10 patients with decreased infarct-CBF despite expanded Treatment in Cerebral Infarction (eTICI) 2c or 3 recanalization was identified (likely related to the no-reflow phenomenon). Outcome was significantly worse in this group compared to the remaining cohort. In conclusion, ASL-derived %CBF difference from the DWI-positive infarct territory independently predicted functional independence, but %CBF difference was not significantly associated with an increased risk of HT.

Activities of daily living limitation and functional decline during hospitalization predict 180-day readmission and mortality in older patients with pneumonia: A single-center, retrospective cohort study

BackgroundThe role of activities of daily living (ADL) as a predictor of adverse outcomes in patients with pneumonia is unclear. This study aimed to assess the association between ADL, including physical and cognitive function, and death or readmission in older inpatients with pneumonia. MethodsThis retrospective, single-center, observational study included consecutive older inpatients with pneumonia between October 2018 and December 2019. ADL was assessed using the Functional Independence Measure (FIM). Functional decline during hospitalization was defined as a decrease of at least 1 point in FIM at discharge from admission. The primary outcome was the time to composite 180-day mortality and readmission from any cause after discharge. ResultsIn total, 363 patients (median [interquartile range] age: 80 [73–86] years, male: 68 %) were divided according to the median FIM scores (≥100, n = 183 and < 100, n = 180). Among the patients, 25 experienced functional decline during hospitalization, 69 were readmitted, and 17 died. In the Kaplan–Meier analysis, both the lower FIM group and the functional decline group had significantly lower event-free rates than the higher FIM groups and the non-functional decline groups (log-rank test, p < 0.001), respectively. After multivariate analysis, both the lower FIM (adjusted HR, 2.11; 95 % CI, 1.24–3.58; p = 0.006) and functional decline (adjusted HR, 3.18; 95 % CI, 1.44–7.05; p = 0.005) were significantly associated with the primary outcome. ConclusionsIn older patients hospitalized with pneumonia, ADL limitations at discharge and a decline in ADL were associated with poor outcomes.

Comprehensive feedback on user experiences with brain injury identification cards.

Brain injuries are often "invisible" injuries that can have lifelong consequences including changes in identity, functional independence, relationships, and reduced participation in daily activities. Survivors of brain injury experience stigma and challenges related to the misattribution of symptoms to other causes that are significant barriers to recovery and adjustment. Changes in policy and other large-scale interventions are cited as an underexplored, yet critical path to reducing the impact of brain injury. The present study sought to comprehensively characterize the impact of one such initiative-Brain Injury Identification Cards-among survivors to further refine the resource. In this cross-sectional qualitative focus group study, we recruited 16 individuals with a history of brain injury via email listservs of individuals who registered for a Brain Injury Identification Card. We used rapid data analysis with a hybrid of deductive and inductive analytic strategies to identify themes within a priori domains. We extracted themes within four domains: (a) process and reasons for obtaining cards; (b) overall impressions of the cards; (c) uses of the cards; and (d) feedback and proposed changes. Participants described the process of obtaining cards as straightforward and shared wide-ranging benefits across domains, including improving survivors' sense of safety, self-advocacy, and ability to participate in daily activities. Findings highlight the utility of Brain Injury Identification Cards for improving community understanding of brain injury symptoms and how injury-related challenges may manifest in daily life.

Behavioral Risk Profiles of Stroke Survivors Among US Adults: Geographic Differences Between Stroke Belt and Non-Stroke Belt States.

Stroke, a leading cause of illness, death, and long-term disability in the US, presents with significant disparities across the country, most notably in southeastern states comprising the "Stroke Belt." This study intended to identify differences between Stroke Belt states (SBS) and non-Stroke Belt states (NSBS) in terms of prevalence of stroke, sociodemographic and behavioral risk factors, and health-related quality of life (HRQOL). We analyzed data from the 2019 Behavioral Risk Factor Surveillance System to compare demographic characteristics, risk factors, physical activity adherence, functional independence, and HRQOL among stroke survivors in SBS and NSBS. Of 18,745 stroke survivors, 4,272 were from SBS and 14,473 were from NSBS. Stroke was more prevalent in SBS (odds ratio [OR] = 1.39; 95% CI, 1.35-1.44; P < .001), with significant differences by age, sex, and race and ethnicity, except for Hispanic ethnicity. Selected stroke risk factors were more common in every category in SBS. Stroke survivors in SBS were less likely to meet physical activity guidelines for aerobic (OR = 0.77; 95% CI, 0.69-0.86; P < .001) and aerobic and strengthening combined (OR = 0.77; 95% CI, 0.70-0.86; P < .001) activities. Stroke survivors in SBS were more likely to not meet either physical activity guideline (OR = 1.31; 95% CI, 1.22-1.41; P < .001). Living in SBS significantly increased the odds of stroke occurrence. Stroke survivors from SBS reported lower HRQOL and insufficient physical activity as well as lower functional independence. Specific strategies are needed for residents of SBS, with a focus on policies and primary and secondary prevention practices across healthcare professions.

A machine learning model based on results of a comprehensive radiological evaluation can predict the prognosis of basal ganglia cerebral hemorrhage treated with neuroendoscopy.

Spontaneous intracerebral hemorrhage is the second most common subtype of stroke. Therefore, this study aimed to investigate the risk factors affecting the prognosis of patients with basal ganglia cerebral hemorrhage after neuroendoscopy. Between January 2020 and January 2024, 130 patients with basal ganglia cerebral hemorrhage who underwent neuroendoscopy were recruited from two independent centers. We split this dataset into training (n = 79), internal validation (n = 22), and external validation (n = 29) sets. The least absolute shrinkage and selection operator-regression algorithm was used to select the top 10 important radiomic features of different regions (perioperative hemorrhage area [PRH], perioperative surround area [PRS], postoperative hemorrhage area [PSH], and postoperative edema area [PSE]). The black hole, island, blend, and swirl signs were evaluated. The top 10 radiomic features and 4 radiological features were combined to construct the k-nearest neighbor classification (KNN), logistic regression (LR), and support vector machine (SVM) models. Finally, the performance of the perioperative hemorrhage and postoperative edema machine learning models was validated using another independent dataset (n = 29). The primary outcome is mRS at 6 months after discharge. The mRS score greater than 3 defined as functional independence. A total of 12 models were built: PRH-KNN, PRH-LR, PRH-SVM, PRS-KNN, PRS-LR, PRS-SVM, PSH-KNN, PSH-LR, PSH-SVM, PSE-KNN, PSE-LR, and PSE-SVM, with corresponding areas under the curve (AUC) values in the internal validation set of 0.95, 0.91, 0.94, 0.52, 0.91, 0.54, 0.67, 0.9, 0.72, 0.92, 0.92, and 0.95, respectively. The AUC values of the PRH-KNN, PRH-LR, PRH-SVM, PSE-KNN, PSE-LR, and PSE-SVM in the external validation were 0.9, 0.92, 0.89, 0.91, 0.92, and 0.88, respectively. The model built based on computed tomography images of different regions accurately predicted the prognosis of patients with basal ganglia cerebral hemorrhage treated with neuroendoscopy. The models built based on the preoperative hematoma area and postoperative edema area showed excellent predictive efficacy in external verification, which has important clinical significance.

Specific Contribution of the Transversus Abdominis for Postural Control Against Perturbation Caused by Kinesthetic Illusion.

Functional independence of the transversus abdominis (TrA) from other trunk muscles for postural control is still unclear. This study aimed to clarify the specific function of the TrA to control standing posture by vibratory stimulation of the triceps surae. Fifteen men participated in this study. Muscle activity of the TrA, internal oblique, lumbar multifidus, gluteus maximus, rectus femoris, biceps femoris, gastrocnemius, and tibialis anterior was measured using fine-wire and surface electrodes. Participants were asked to maintain a quiet standing posture with and without vibration of the triceps surae, which induced a kinesthetic illusion and the concomitant backward sway of the body. The muscle activity of each muscle for 10s was extracted with and without vibration. The muscle activity levels were compared between the conditions by a paired t-test or Wilcoxon signed-rank test. The activity of the TrA and rectus femoris was increased, whereas the internal oblique showed no change as a result of the induced kinesthetic illusion. In addition, the activity of the multifidus and biceps femoris was decreased. The TrA and rectus femoris could contribute to control the backward sway of the body. Furthermore, the TrA may have functional independence from the internal oblique during standing postural control. These results warrant further study in patients with low back pain.

Safety and Effectiveness Analysis of Endovascular Treatment vs Standard Medication Treatment in Patients with Progressive AIS-LVO Stroke in the Ultra-late Time Window: A Propensity Score Matched Cohort Study

The time from onset to symptom deterioration in ischemic stroke often exceeds 24 hours, and this ultra-late time window is excluded from the endovascular treatment (EVT) guideline. This study aimed to explore the safety and efficacy of EVT in progressive acute ischemic stroke with large vessel occlusion (AIS-LVO) stroke patients with onset to symptom deterioration times of 24h-7 days. Progressive stroke patients with time window of 24h-7 days treated at our hospital over the past 6 years were retrospectively collected. Patients were categorized into EVT and standard medication treatment (SMT) group based on the treatment approach. Patients were matched using propensity score matching (PSM). Safety outcomes primarily included 3-month mortality and symptomatic intracranial hemorrhage (sICH), efficacy outcome primarily included functional independence (3-month mRS≤2). A total of 396 patients were included in the study, with 86(21.7%) in EVT and 310(78.3%) in SMT group. There were 140 remaining after PSM, with 70 in each group (50%). Compared to SMT group, EVT group had higher functional independence (52.9% vs 15.7%, OR=7.504, 95% CI 2.141-14.093, P<0.001) and lower 3-month mortality (14.3% vs 40.0%, OR=0.412, 95% CI 0.099-0.856, P<0.001). EVT was also associated with higher sICH (25.7% vs 5.7%, OR=9.926, 95% CI 1.874-36.547, P<0.001). For patients with progressive AIS-LVO in the ultra-late time window, EVT remains a viable treatment approach.

Development and validation of a functional ability index for older adults: a multicohort study.

The aim of this study was to develop and validate a functional ability index (FAI) that incorporates aspects of intrinsic capacity and environmental factors of older individuals based on the World Health Organization framework of healthy ageing. Data of 7016 participants ≥60years participating in the baseline survey of China Health and Retirement Longitudinal Study was used for the development and internal validation of the FAI. External validation was performed in a separate cohort of 1295 older individuals aged ≥60years. Functional independency was considered the primary outcome and additional proxies of healthy ageing were considered as secondary outcomes. Cluster dendrogram was used to identify the distinct hierarchical clusters of all included variables for inclusion in the FAI. Backward elimination logistic regression model was implemented to identify the most significant variables associated with independency to be included in the FAI. The FAI score ranged from 0 to 19 and individuals having FAI ≥ 12 were more likely to be independent and at lower risk of negative outcomes. For each unit increase in the FAI the risk of having independency increased by 30%-58% cross-sectionally in the two cohorts, whilst the 2-year risk of independency increased by 20%. The FAI demonstrated a C-statistic of 0.73 (95% confidence interval, 0.72 and 0.75) for the primary outcome. The FAI we developed effectively measured the functional ability status of community dwelling older individuals. FAI could serve as a tool for evaluating older individual's functional ability in routine health assessment.

Chronic stroke survivors underestimate their upper limb motor ability in a simple 2D motor task

BackgroundStroke survivors can exhibit a mismatch between the actual motor ability of their affected upper limb and how much they use it in daily life. The resulting non-use of the affected upper limb has a negative impact on participation in neurorehabilitation and functional independence. The factors leading to non-use of the affected upper limb are poorly understood. One possibility is that non-use comes about through inappropriately low confidence in their own upper limb motor abilities.ObjectiveWe asked whether chronic stroke survivors underestimate the motor ability of their affected upper limb.Methods20 chronic stroke survivors (Mean FM: 28.2 ± 10.5) completed a 2D reaching task using an exoskeleton robot. Target sizes were individually altered to ensure success rates were similar for both upper limbs. Prior to each reaching movement, participants rated their confidence about successfully hitting the target (estimated upper limb motor ability).ResultsConfidence ratings were significantly lower for the affected upper limb (estimated ability), even though it was equally successful in the reaching task in comparison to the less affected upper limb (actual ability). Furthermore, confidence ratings did not correlate with level of impairment.ConclusionsOur results demonstrate that chronic stroke survivors can underestimate the actual motor abilities of their affected upper limb, independent of impairment level. Low confidence in affected upper limb motor abilities should be considered as a therapeutic target to increase the incorporation of the affected upper limb into activities of daily living.

The Mediating Effect of Information Technology Usage on the Relationship of Internal Audit Processes and Internal Auditor Competence towards Internal Audit Effectiveness: Evidence from the Chinese Financial Sector

The effectiveness of internal auditing is determined by various factors, such as the independence of the internal audit function, auditors&amp;rsquo; competence, effective audit planning, efficient audit processes, and support from senior management. The digitalization and informatization of modern enterprises have transformed the way companies are managed and have similarly impacted internal audit practices. Informatization not only alters traditional internal audit processes but also changes auditors&amp;rsquo; ways of working and thinking. From the perspective of resource-based theory, the effective allocation and full utilization of human, technological and organizational resources can enhance the effectiveness of internal audit. Therefore, the purpose of this study is to examine the impact of internal audit processes (IAP) and internal auditor competence (IAC) on internal audit effectiveness (IAE), as well as the mediating effect of information technology usage (ITU) on the relationship between IAP and IAC and IAE. To test the proposed hypotheses, a questionnaire survey was conducted within Chinese financial enterprises, yielding a total of 133 valid responses. Statistical data analysis was performed using the partial least squares structural equation modelling (SEM-PLS) method. The results indicate that both IAP and IAC have a significant impact on IAE and ITU. Furthermore, ITU serves as a mediating factor, enhancing the positive contributions of IAP and IAC to IAE.

The role of pulmonary rehabilitation in improving lung functions in patients with ankylosing spondylitis

Background Ankylosing spondylitis (AS) is a chronic inflammatory disease characterized by axial and peripheral entheseal inflammation and new bone production(1). The development of syndesmophytes, enthesophytes, and spinal fusion along the course of the disease is linked to chronic pain, functional impairment, and disability(2). Fibrosis of the upper lobes of the lungs (interstitial lung disease) and chest wall abnormalities are two of the emerging forms of pulmonary involvement in AS. (3). Pulmonary rehabilitation is a multifaceted program of education, counselling, breathing exercises, and other modalities that can increase the patient’s independence and ease of functioning(4). Aim To estimate the role of pulmonary rehabilitation in enhancing lung function in AS individuals in relation to disease activity, clinical, and functional parameters. Patients and methods This study was an interventional study: single-arm group (prospective randomized clinical study). Thirty people (30) participated in that study from those presented to Physical Medicine, Rheumatology and Rehabilitation inpatient and outpatient clinic at Ain Shams University hospitals, diagnosed as radiographic axial spondyloarthropathy (SPA) from 02/2022 to 12/2022. All patients underwent pulmonary rehabilitation program and were exposed to a detailed history, clinical, and pulmonary function testing. Disease activity was evaluated by Ankylosing Spondylitis Disease Activity Score C-reactive protein (ASDAS-CRP), Valuation of function by using Bath Ankylosing Spondylitis Functional index (BASFI), 6-Minute walk test (6MWT), the Modified Borg Dyspnoea Scale (MBS), and Timed Up and Go (TUG) test. All function and clinical scores were done at baseline and repeated after completing pulmonary rehabilitation program. Result The mean age of patients was 36.57 ± 7.83 years (23–45 years), with a median disease duration of (5 (3–9) years). In total, there were 19 out of the studied patients with restrictive pattern. With comparison between pre- and postintervention of pulmonary rehabilitation, there was a significant statistical difference in all, disease activity (ASDAS and BASFI) and functional (MBS, TUG, and 6MWT) parameters (P &lt;0.001), except for occiput to the wall. Regarding pulmonary function tests, including forced vital capacity (FVC), expiratory volume in one second (FEV1), and peaked expiratory flow (PEF), there was a statistically significant change at baseline and at the end of exercise (P &lt;0.001). Conclusion Improved respiratory function and disease activity and overall functional activity are possible outcomes of pulmonary rehabilitation programs in combination with other rehabilitation interventions.

The effect of trunk exercises with hip strategy training to maximize independence level and balance for patient with stroke: Randomized controlled study.

Balance while seated and the capacity to conduct selective trunk movements are significant predictors of functional outcomes following stroke. Patients with inappropriate muscle activation and inadequate movement control in the trunk muscles cause mobility and daily function difficulties. Stroke patients have weak leg muscles and decreased balance, resulting in compensatory changes. Functional postural strategy training is necessary to restore balance in these patients. Few studies have examined the effect of physical therapy trunk exercises with hip strategy training on improving balance and increasing independence after stroke. This study aimed to explore the effect of selective trunk exercises (STE) with hip strategy training in improving balance in patients with stroke as well as independence levels. A multicenter inpatient stroke treatment randomized pre- and post-test control trial. Forty-six stroke survivors were randomly allocated to experimental or control groups (n=23 each). The experimental group received hip strategy training and trunk exercises. All groups received Neuro-Developmental Treatment (NDT)-based physical therapy four times a week for 6weeks. Trunk impairment scale, Berg Balance Scale (BBS), and functional independence measure (FIM) measured static and dynamic seated balance, functional balance, and trunk movement coordination pre- and post-therapy. The experimental group's post-therapeutic measures were substantially higher than the control group. The experimental group's TIS score, and subscale improved more than the control group. The experimental group considerably increased the BBS score. The experimental group also showed greater FIM gains. This study demonstrated that adding STE in conjunction with hip strategy training to patients after has a positive impact on trunk control while maintaining static and dynamic sitting balance, functional balance, and independence levels which are effective in stroke rehabilitation.

Red cell distribution width and outcome in acute ischemic stroke patients

IntroductionSeveral biomarkers have proven prognostic value for acute ischemic stroke (AIS) patients. Red cell distribution width (RDW) has been associated with several diseases and all-cause mortality and suggested as an independent predictor of Ischemic Stroke severity and outcome. This study aimed to investigate RDW as an independent predictor of functional outcome and death in the 3 months following AIS. MethodsPatients with AIS were divided in four groups according to the quartile of the RDW value at admission. Baseline characteristics of patients in each RDW quartile were compared by Chi-square or Kruskal-Wallis tests, as applicable. We prospectively analyzed the patients for functional outcome in the 3 months following the event. Functional outcome (dichotomized as independent [0-2] or dependent [>2] according to the modified Rankin Scale score) and 90-day mortality was compared between the 4 groups. To conduct this evaluation, univariable and multivariable binary logistic regression analysis for functional independence and mortality at 3 months was conducted, considering the variables previously identified as potential confounders. ResultsThe study's final population was of 416 patients. The patients in higher RDW quartiles were older (p<0.001), had lower blood hemoglobin (p<0.001), higher C reactive protein levels (p=0.017), higher BNP values (p<0.001) and more frequently suffered from atrial fibrillation (p=0.015) and heart failure (p=0.004). Univariate analysis showed a negative association between RDW-Q4 and independence at 3 months (p=0.024), which wasn't verified in the multivariate analysis (p=0.871). Univariate analysis also identified a positive association between RDW-Q4 and 90-day mortality (p=0.049), which was not confirmed in the multivariate analysis (p=0.289). ConclusionsWhen adjusted to potential confounders, RDW does not predict functional outcome or death in the 90 days after acute ischemic stroke.

Profile of antiplatelet regimens for emergent carotid stenting in tandem occlusion. Systematic review and meta-analysis

AimTo investigate the optimum antiplatelet therapy regimen (APTR) for emergent carotid artery stenting following mechanical thrombectomy (MT) in stroke patients with tandem occlusion. MethodsA literature search was performed on Pubmed/OVID/Cochran's CENTRAL database for studies from 2015 to 2022. Patient characteristics, antiplatelet regimen type, mTICI, 90 days-mRS, acute in-stent thrombosis (AIST), mortality, intracranial hemorrhage (ICH), and sample size were recorded. Exclusion criteria were non-English literature, sample size < 5 patients, other anticoagulant/antiplatelet therapy, and 100 % stent insertion in one study arm. The studies were assessed using MINORS/GRADE. Meta-analysis and meta-regression with a random effects model were performed. The outcomes were: 90 days-mRS, death, AIST and ICH ResultsFive-hundred-twenty-four studies were retrieved. After applying the exclusion criteria, the final population included 19/534 studies (3.6 %) for 880 patients (46.3 per article). I^2 and Q’s Cochrane were 86.4 % and 132.5 for mRS, 19.9 % and 17.5 for death, 0 % and 9.4 for acute in-stent thrombosis and 62.1 % and 39.7 for intra-cranial haemorrhages, respectively.Patients in the aspirin subgroup had a significantly lower rate of functional independence (mRS≤2) than those in the DAPT subgroup (47 % [CI95 % 42.0 %-52.0 %] vs. 61.9 % [CI95 % 50.8–72.9]; p=0.0007;OR 0.75[CI95 % 0.56–1.01], p=0.06). DAPT significantly decreased the death rate compared with aspirin (8.6 % [CI95 % 5.3 %-11.9 %] vs. 16.7 % [CI95 11.1 %-22.2 %]; p=0.0012). Anti-GPIIb/IIIa demonstrated a trend of increasing the probability of mortality versus DAPT (OR 1.88[CI95 % 0.93–3.86], p=0.08.No significant differences were observed between AIST and ICH in the treatment groups. ConclusionDAPT may increases the chance of obtaining an mRS score ≤2 and reduces mortality.

Site-specific skeletal muscle mass and functional prognosis in geriatric stroke patients

BackgroundEvidence is scarce regarding prognostic value of site-specific muscle mass in geriatric stroke survivors. We aim to assess the association between four measures of muscle mass, namely the skeletal muscle mass index of the limbs (SMI), upper limb SMI (USMI), lower limb SMI (LSMI), and trunk muscle mass index (TMI), and the functional prognosis in stroke patients. MethodsThis study conducted a retrospective cohort analysis involving post-acute stroke inpatients. Muscle mass data were obtained through bioelectrical impedance analysis and computed by dividing each muscle mass by the square of the height. The study outcomes included the Functional Independence Measure (FIM) motor at discharge and FIM-motor gain. Multiple regression analysis was conducted to assess the association between SMI, USMI, LSMI, and TMI with outcomes, while adjusting for confounding factors. ResultsA total of 701 patients (mean age 72.8 years, 374 males) were analyzed. As a result, LSMI (β = 0.089, P = 0.003) and SMI (β = 0.083, P = 0.008) were significantly associated in the FIM-motor at discharge, with LSMI showing a stronger association. USMI (β = 0.019, P = 0.521) and TMI (β = 0.035, P = 0.231) showed no significant association. LSMI (β = 0.124, P = 0.003) and SMI (β = 0.116, P = 0.008) were significantly associated with FIM-motor gain; however, USMI (β = 0.027, P = 0.521) and TMI (β = 0.049, P = 0.231) showed no significant association with FIM-motor gain. ConclusionsDifferential associations were observed between site-specific muscle mass and functional prognosis in post-stroke patients. Among these, lower limb muscle mass was most strongly associated with activities of daily living (ADL) recovery.
