However, as the home is a challenging environment for design, it is essential that such designs are closely linked to stakeholder needs. This paper continues previous work by the authors linking stakeholder needs to the design of an at-home stroke rehabilitation robot for the upper limb. The proposed design is a constrained cable robot with a vertical workspace, capable of supporting and measuring the motion of a stroke survivor’s arm and hand during therapy activities, with a modular end effector design to simulate a variety of activities of daily living. The technical requirements of the design are described and linked to research on therapy activities, activities of daily living, and anthropometry. The kinematic and dynamic requirements for the design are validated in experiments. Potential improvements for the design include adding powered hand modules to assist users with hand impairments, adding a third rotational degree of freedom, and investigating parallel-spring motor designs that could reduce power consumption.","PeriodicalId":73318,"journal":{"name":"IEEE transactions on medical robotics and bionics","volume":"7 2","pages":"743-754"},"PeriodicalIF":3.4,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143949156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing multimodal approaches predominantly extract global specificity at a single temporal scale, which neglects local dynamic characteristics. This limitation hinders the effective capture of global-local temporal information, resulting in restricted performance and frequent misclassification of dynamic gestures. To this end, we propose a novel global-local Fusion model, termed Temporal-spatial Dependence Fusion (TsdFusion), for sEMG-ACC-based HGR. TsdFusion harnesses temporal-spatial dependencies (Tsd) from multi-time scale handcrafted features and employs a Convolution-Transformer framework for global-local fusion, thus enriching local dynamic information while preserving global insights. Specifically, the Tsd inputs are independently constructed from sEMG and ACC through multi-time scale window segmentation and feature engineering. Furthermore, the global and local temporal-spatial correlations within unimodal Tsd inputs are characterized by the unimodal transformer and dimension-wise convolution modules, respectively. Subsequently, a Convolution-coupled-transformer progressive hierarchical fusion module effectively integrates intramodal specificity and intermodal hierarchical relationship for final prediction. Evaluations on four public datasets, including transradial amputees and healthy subjects, demonstrate TsdFusion outperforms the state-of-the-art multimodal HGR methods. The TsdFusion effectively recognizes dynamic gestures, facilitating promising HGR-based interaction for prostheses or assistance robotics.","PeriodicalId":73318,"journal":{"name":"IEEE transactions on medical robotics and bionics","volume":"7 2","pages":"723-733"},"PeriodicalIF":3.4,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143949155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adoption of robotic technology offers the potential to bring intra-operative radiation exposure down to a minimum, or even eliminate it. Non-ionizing approaches, such as Intravascular Ultrasound (IVUS), are progressively explored as standalone or fluoroscopy-adjunct techniques for 3D vasculature reconstruction. We have previously demonstrated the feasibility of real-time 3D Main Vessel (MV) modeling from the fusion of IVUS and EM pose data obtained from sensors embedded at the tip of a robotic catheter. This paper proposes to advance MV modeling towards a comprehensive radiation-free 3D guidance framework by means of intra-operative Side Branch (SB) detection and modeling. Two models are proposed to approximate the geometry of SB vessel ostia: a sphere and a cylinder. An Unscented Kalman Filter (UKF) recursively estimates the state of these models considering the MV model, while the catheters navigates through the vessel. In silico and in vitro validation results show the potential clinical value of the proposed strategy for facilitating safer robotic catheter steering.","PeriodicalId":73318,"journal":{"name":"IEEE transactions on medical robotics and bionics","volume":"7 2","pages":"443-454"},"PeriodicalIF":3.4,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these challenges, a significant research interest is growing in automating these manual procedures. Continuum robots represent a promising approach, thanks to their ability to navigate confined spaces. However, their nonlinear behavior presents challenges in modeling and control. In this study, we developed a robust position control method for a variable-length tendon-driven continuum robot. We designed a control system that effectively tracks the desired target positions by employing a constant curvature model and a Jacobian-based control algorithm with real-time position feedback. We assessed the stability of our system through Lyapunov analysis, demonstrating reliable convergence to these target positions. Experimental validation conducted in a cardiovascular phantom demonstrated significant improvements with respect to the state of the art. Our method achieved a trajectory following error of approximately 2.43 mm [1.63, 3.23] and a target position error of about 1.92 mm [1.73, 3.13]. Moreover, the computation time per trajectory point was reduced to approximately 0.04 seconds, highlighting enhanced computational efficiency. These results showcase improved accuracy and efficiency in minimally invasive mitral valve repair procedures.","PeriodicalId":73318,"journal":{"name":"IEEE transactions on medical robotics and bionics","volume":"7 2","pages":"562-571"},"PeriodicalIF":3.4,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While user-dependent (DEP) estimators generally outperform user-independent (IND) estimators, they require the pre-collection of DEP training data. In contrast, our real-time algorithm adapts IND estimators to self-labeled DEP data generated during walking, eliminating the need for pre-collected datasets. The algorithm also features a biomimetic scaling mechanism that adjusts prosthetic assistance based on speed estimates. We evaluated our algorithm on novel subjects (N=10) with unilateral above-knee amputations during treadmill and overground walking. For treadmill trials, when adapted with estimated and ground truth labels, estimators achieved mean absolute errors (MAEs) of 0.074 [0.023] (mean, [standard deviation]) and 0.074 [0.018] m/s, respectively, reflecting a significant 28% (p ¡ 0.05) reduction in MAE compared to non-adapted estimators. For overground trials, treadmill-adapted estimators demonstrated a significant 18% (p ¡ 0.05) reduction in MAE compared to non-adapted estimators.

The industry has mainly emphasized on quasi-passive hydraulic solutions, whereas most research works have focused on powered devices, employing electric actuation. The former have an energetically passive effect at the knee joint, for which they often lack in providing versatility and movement robustness for the wearer. Powered prostheses can address these deficiencies, but are often rejected as they struggle to fulfill other user needs (e.g., weight and acoustic noise). Correspondingly, recent studies have emerged that attempt to significantly attenuate the deficiencies of fully powered prosthesis knees, partially sacrificing on device versatility. Recognizing the state-of-the art difficulties in balancing active assistance and user needs fulfilment, this work analyses human-centered design perspectives and their prospects for prosthetic development, in light of the often diverging user needs. We conclude that various types of both explored and yet unexplored semi-powered solutions may have the potential to provide the better trade-off between quasi-passive and fully powered prosthetic devices.","PeriodicalId":73318,"journal":{"name":"IEEE transactions on medical robotics and bionics","volume":"7 2","pages":"429-442"},"PeriodicalIF":3.4,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10924214","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed 4-DOF mechanism employs parallelogram motion replication to relocate the bulky instrument insertion drive from the end-effector to the proximal linkage on the base, minimizing obstruction to the microscope’s field of view and the surgical environment. The mechanism’s orthogonal or coincident arranged degrees of freedom, paired with independent drive units, facilitate calibration and enhance control accuracy. A minimized internal constraint force optimization method was proposed to improve RCM point stability and tip positioning accuracy. The mechanism’s configuration and parameters were optimized through an analytical mechanics model, effectively reducing the constraint force on the internal components under the same external loads, thereby minimizing deformation and maintaining accuracy. To enhance robot compatibility, modular surgical instruments with a quick-change coupler were developed based on the analysis of traditional instruments’ characteristics.
