Robotic-assisted rehabilitation, particularly with the Hybrid Assistive Limb (HAL), has emerged as an innovative approach to enhance motor recovery and functional outcomes. HAL is a wearable exoskeleton that detects bioelectrical signals and provides real-time support, offering unique opportunities for task-specific and intensive neurorehabilitation.ObjectiveThis narrative review summarizes recent clinical evidence on the application of HAL in stroke rehabilitation, focusing on its effects on gait, upper limb recovery, activities of daily living (ADL), and safety, while discussing its limitations and future directions.MethodsA literature search of PubMed and Scopus was conducted for studies investigating HAL-assisted rehabilitation in stroke patients. Eligible studies included randomized controlled trials, systematic reviews, pilot studies, and relevant narrative reviews.ResultsEvidence from randomized and non-randomized studies suggests that HAL-assisted rehabilitation can improve gait velocity, balance, and, to a lesser extent, upper limb function in both acute and chronic stroke populations. Several systematic reviews and RCTs (2022-2025) have confirmed its potential benefits compared to conventional physiotherapy, though findings remain heterogeneous. HAL is generally safe and well tolerated, but high costs, limited availability, and methodological variations across studies constrain generalizability.ConclusionHAL-assisted rehabilitation represents a promising adjunct to conventional stroke therapy, with growing evidence supporting its efficacy in motor recovery. However, current data are limited by small sample sizes, inconsistent protocols, and lack of long-term follow-up. Large-scale, multicenter randomized controlled trials are warranted to establish its clinical utility, cost-effectiveness, and integration into routine care.","PeriodicalId":48978,"journal":{"name":"Technology and Health Care","volume":" ","pages":"9287329261440743"},"PeriodicalIF":1.8,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147700595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to develop and validate a predictive model for estimating one-year mortality risk in ICU-admitted ischemic stroke patients.MethodsIn this retrospective cohort study, data from 1974 ischemic stroke patients were extracted from the MIMIC-IV database. Patients were randomly allocated into a training set (n = 1582) and a test set (n = 392) in an 8:2 ratio. Five machine learning algorithms (CART, RF, SVM, GBM, and NB) were employed for initial feature screening. Key predictors were subsequently integrated into a multivariate logistic regression model, which was visualized as a nomogram. The model's performance was evaluated using discrimination, calibration, and clinical utility metrics and was compared against established severity scores (SOFA, SAPS II, LODS, OASIS, GCS).ResultsThe final nomogram incorporated nine predictors: age, heart rate, weight, glucose, anion gap, calcium, alkaline phosphatase (ALP), red cell distribution width (RDW), and mean corpuscular hemoglobin concentration (MCHC). The model demonstrated an AUC of 0.739 (95% CI: 0.715-0.764) in the training set and 0.737 (95% CI: 0.688-0.786) in the test set. Calibration curves indicated good agreement between predictions and observations. Decision curve and clinical impact curve analyses confirmed the nomogram's favorable clinical net benefit, and it outperformed all comparator scoring systems in discriminatory ability.ConclusionsWe developed and validated a practical nomogram that effectively integrates key clinical variables to predict one-year mortality risk in ICU patients with ischemic stroke.

The signals were preprocessed using individualized spectral filtering and a dual-stage normalization approach. First, dynamic maximum voluntary contraction (MVC) based min-max normalization was applied to standardize signal amplitudes. Second, functional weighting was used to scale each muscle's activation based on its biomechanical contribution to the movement. The processed signals were used as input to an OpenSim elbow model, and resulting joint kinematics were compared to reference motion data captured by an Xsens system.ResultsThe EMG-driven OpenSim model showed strong agreement with the Xsens data, with correlation coefficients exceeding 0.98 and root mean square error (RMSE) values below 8°. While a minor systematic offset was observed, joint angle trajectories remained consistent and physiologically plausible across trials.ConclusionThe proposed subject-specific EMG preprocessing pipeline enhances the accuracy and interpretability of biomechanical models.

We divided the grafts into spike and non-spike waveform groups, and assessed the patency of grafts. Additionally, we constructed an ideal model of CABG, we also calculated and extracted the hemodynamic parameters of the grafts.ResultsFor immediate patency, the occlusion rates of spike and non-spike waveforms of left internal mammary artery(LIMA) were 0 and 5.13%, those of saphenous vein graft(SVG) were 8.59% and 5.79%. As for medium-long term patency, the occlusion rates of spike and non-spike waveforms were 0 and 12.56% for LIMA, and 42.47% and 16.84% for SVG.
