These complications are linked to imbalances in glenohumeral muscle forces, which cause eccentric loading on the edge of the glenoid. The purpose of this study was to develop patient-specific musculoskeletal models of TSA patients using their kinematics acquired with high-speed stereo radiography (HSSR) to predict glenohumeral joint loading and muscle forces for abduction and flexion and describe how these loads differ from their native contralateral side. CT data were collected for both shoulders of 6 TSA patients (3 anatomic, 3 reverse). Models were developed using CT reconstructions of each patient's scapula, humerus, and placed implant geometry with CT derived alignment. Scapula morphing was used to create personalized muscle attachment sites. Simulation of abduction and flexion to quantify muscle and joint forces was driven with limb-specific HSSR kinematics. Reverse TSA increased superior shear force by 11.2% bodyweight (BW) and decreased medial force by 27.5% BW compared to each patient's contralateral shoulder. Lateral deltoid elevation moment arms and stability ratios increased 9.61 mm and 0.58, respectively. Anatomic TSA patients increased humeral internal rotation 52.7 degrees and decreased rotator cuff activation 9.4% BW. Patient-specific musculoskeletal models quantified differences in glenohumeral joint mechanics. This study elucidated muscle and kinematic mechanisms that could lead to edge loading and glenoid loosening in TSA and can inform personalized surgical planning for implant alignment with the goal of improving patient outcomes.","PeriodicalId":54871,"journal":{"name":"Journal of Biomechanical Engineering-Transactions of the Asme","volume":" ","pages":"1-37"},"PeriodicalIF":1.7,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144487081","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}

To address this, annular mechanical properties were quantified following static shear loading using a porcine model. Methods Twelve porcine cervical FSUs were dissected, with posterior bony elements removed to isolate shear to the intervertebral disc. Specimens were randomized into two conditions: (1) Shear-loaded (100 N static anterior shear applied to C3/C4, n=6) or (2) Control (0 N, n=6). Shear force was applied via a pin through C4, secured to a testing system to prevent rotation while C3 was clamped such that anterior shear of C3 with respect to C4 resulted. Following 1 hour of loading, two anterior annulus samples were extracted per specimen. The first samples underwent circumferential tensile testing, while the other was prepared for a peel test to assess interlamellar adhesion. Results Tensile properties in the circumferential direction remained unchanged after shear loading. However, interlamellar adhesive stiffness decreased by 52% (p=0.02), and adhesive strength dropped by 46% (p=0.02) in shear-loaded specimens compared to controls. Discussion Shear loading weakened the interlamellar matrix, reducing resistance to delamination and compromising disc integrity. These findings suggest that prolonged shear loading may contribute to early-stage disc damage.","PeriodicalId":54871,"journal":{"name":"Journal of Biomechanical Engineering-Transactions of the Asme","volume":" ","pages":"1-17"},"PeriodicalIF":1.7,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144477935","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}

The musculoskeletal model had a 12 degree of freedom (DoF) knee joint with personalized articulating surfaces. First, model?s muscle parameters underwent calibration, followed by the EMG-assisted analysis. To assess model?s performance, we compared estimated knee biomechanics against four other simulation approaches, i.e., a 12 DoF knee model with either 1) uncalibrated EMG-assisted and 2) static-optimization (SO) neural solution; and a conventional 1 DoF knee model with either 3) EMG-assisted or 4) SO neural solution. The performance of the models was assessed against in vivo measured values from two grand challenge datasets. For estimated muscle excitations and joint contact force (JCF), the EMG-assisted models outperformed the SO solutions. Compared to the EMG-assisted 1 DoF knee, using EMG-assisted 12 DoF knee improved estimation of muscle excitations, joint moments, and transverse tibiofemoral JCF to a greater extent than compressive tibiofemoral JCF. To estimate compressive tibiofemoral JCF (during walking), the EMG-assisted model with personalized 1 DoF knee may suffice. However, the EMG-assisted 12 DoF knee model is recommended for a more accurate estimation of joint moments, muscle forces, and compressive and transverse tibiofemoral JCF, especially when these quantities can be affected, e.g., due to musculoskeletal disorders. The developed simulation framework provides a viable approach for estimating knee biomechanics accounting for personalized muscle excitation strategy and knee articulating geometries.","PeriodicalId":54871,"journal":{"name":"Journal of Biomechanical Engineering-Transactions of the Asme","volume":" ","pages":"1-44"},"PeriodicalIF":1.7,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144334513","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}

Existing systems typically perform discrete gestures such as pointing or grasping, by employing electromyography (EMG) or ultrasound (US) technologies to analyze muscle states. While detecting finger activation has been done in the past, we are interested in detection, or inference, done in the context of fine motions that evolve over time. Examples include motions occurring when performing fine and dexterous tasks such as typing on a keyboard or playing a musical instrument. We consider this task as an important step towards higher adoption rates of robotic prostheses among arm amputees, as it has the potential to dramatically increase functionality in performing daily tasks. To this end, we present an end-to-end robotic system, which can successfully infer fine finger motions in real time. This is achieved by modeling the hand as a robotic manipulator and using it as an intermediate representation to encode muscles&#39; dynamics from US images. We evaluated our method by collecting data from a group of subjects and demonstrating how it can be used to replay music played on the piano or text typed on a computer keyboard. To the best of our knowledge, this is the first study demonstrating these downstream tasks within an end-to-end system.","PeriodicalId":54871,"journal":{"name":"Journal of Biomechanical Engineering-Transactions of the Asme","volume":" ","pages":"1-25"},"PeriodicalIF":1.7,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144250955","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}

Murray published a fundamental law of physiology relating the form and function of branched vessels. Murray's Law predicts that the diameter of a parent vessel branching into two child branches is mathematically related by a cube law based on parabolic flow and power minimization with vascular volume. This law is foundational for computational analyses of branching vascular structures. However, pulmonary arteries exhibit morphometric and hemodynamic characteristics that may deviate from classical predictions. This study investigates the morphometry of pulmonary arterial networks, examining relationships between parent and child vessel diameters across species. We analyzed three-dimensional segmentations of pulmonary arterial geometries from healthy subjects across four species: human (n=7), canine (n=5), swine (n=4), and murine (n=3). Our findings reveal an average exponent value of 2.31 (± 0.60) in humans, 2.13 (± 0.54) in canine, 2.10 (± 0.49) in swine and 2.59 (± 0.58) in murine, all lower than the predicted value of 3.0 from Murray's Law. Extending Murray's Law to fully-developed pulsatile flow based on minimal impedance, we show that mean flow is proportional to radius raised to a power between 2.1 and 3, depending on the Womersley number. Our findings suggest that while Murray's Law provides a useful baseline, pulmonary artery branching follows a different optimization principle depending on Womersley number. This study contributes to a deeper understanding of pulmonary arterial structure-function relationships and implications for vascular disease modeling.","PeriodicalId":54871,"journal":{"name":"Journal of Biomechanical Engineering-Transactions of the Asme","volume":" ","pages":"1-16"},"PeriodicalIF":1.7,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144250957","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}

Cornea, the transparent tissue at front of the eye, has a significant role in vision. Because of easy accessibility and comparable dimensions, porcine cornea has been widely used for investigating human corneal properties. There exist contradictory reports on anisotropic mechanical properties of porcine and human cornea. Here, similarities and differences between human and porcine corneal biomechanics were characterized using a biaxial testing machine (ElectroForce Planar Biaxial TestBench, TA Instruments) and a uniaxial testing device (RSA-G2 Solids Analyzer, TA Instruments). Furthermore, transmission electron microscopy was done to characterize the microstructure of samples. Both biaxial and uniaxial experiments showed that neither human nor porcine cornea had anisotropic tensile properties along SI and NT directions. The tensile properties obtained from uniaxial tests were significantly lower than biaxial measurements (P < 0.05). Both testing methods gave significantly larger peak stress and tangent modulus for human cornea (p < 0.05). The human corneal collagen fibril diameter, interfibrillar spacing, and lamellar projected thickness were significantly smaller (P < 0.05). The lamellar projected thickness of each species along SI and NT directions was significantly different (P < 0.05). The differences and similarities between mechanical response of porcine and human cornea were discussed in terms of microstructure of their extracellular matrices. It was concluded that researchers should be informed about the mechanical differences between human and porcine cornea.","PeriodicalId":54871,"journal":{"name":"Journal of Biomechanical Engineering-Transactions of the Asme","volume":" ","pages":"1-29"},"PeriodicalIF":1.7,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144227748","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}

However, research on phase detection in human crawling remains limited. The research explores whether multi-joint kinematic synergy features provide better accuracy than traditional time-domain features.Methods: Nine healthy adults participated in the study, where accelerometers and pressure sensors were used to capture motion data during crawling. The data were pre-processed and used to define four distinct phases of crawling and kinematic synergy features were extracted using Singular Value Decomposition (SVD)-based Principal Component Analysis (PCA). Machine learning models, including Classification and Regression Trees (CART), K-Nearest Neighbors (KNN), and Error-Correcting Output Codes Support Vector Machines (ECOC-SVM), were trained to recognize the crawling phases. Their performance was compared to that of time-domain features.Results: The phase recognition method based on multi-joint kinematic synergies achieved an average accuracy of 89.37%. Specifically, the accuracy for CART was 88.41%, for KNN was 85.51%, and for ECOC-SVM was 94.20%. In comparison, the phase recognition using traditional time-domain features yielded lower accuracy, with overall accuracies of 78.98% for CART, 76.09% for KNN, and 85.51% for ECOC-SVM Conclusion: The findings demonstrate that using kinematic synergy features significantly improves the accuracy of crawling phase recognition compared to traditional time-domain features.

However, there are few systems specifically designed for pediatric use, and those that do exist are largely cumbersome, bulky, and noncustom devices that ultimately reduce therapy effectiveness. This paper introduces the Cable-Driven Joint System (CDJS), a novel approach for pediatric gait rehabilitation that addresses these shortcomings in a lightweight and compact robotic device using the patient's professionally fitted orthosis. The CDJS consists of a 2.1 kg actuation unit that is held by a clinician which delivers assistive torques through a Bowden cable transmission to a 0.3 kg joint mounted to user-custom bracing. This work details an actuator benchtop evaluation, demonstrating a peak torque of 20 N·m, peak velocity of 7.2 rad/s, bandwidth of 9.7 Hz, and a mass moment of inertia of 58.38 kg cm2. An actuator model was developed and evaluated in simulation, showing a strong correlation with the experimental torque data (R-squared = 0.95) and indicating a transmission efficiency of 72%. In-air gait tracking experiments on an emulated subject showed that the CDJS assisted the subject to track a nominal knee trajectory with an average root-mean-squared error of 2.56 deg at a continuous torque of 1.37 N·m. These results suggest that the cable-driven actuator meets the design requirements for use in pediatric gait rehabilitation and is ready for implementation in clinical device trials.","PeriodicalId":54871,"journal":{"name":"Journal of Biomechanical Engineering-Transactions of the Asme","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143797205","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}
