An understanding of the tissue strains in the RC of the shoulder under normal and pathological conditions can inform surgeons about the conditions needed for restoration of function and the state of the tissue under repair. The current work applied digital image correlation (DIC) to quantify rotator cuff strains with the goals of (1) determining whether the tension created by the supraspinatus (SS) muscle is transmitted without diversion by the structure of the cuff from the supraspinatus to the cuff insertion; and (2) whether releases of the SS tendons at their insertions alter the strain field in the region away from the cuff insertion. DIC methods recorded the bursal-side cuff strains created using a shoulder simulator, which could apply physiologic loads to the cuff muscles. The SS and infraspinatus (IS) insertions of the humerus were sequentially released while muscle loads were applied. The first principal strains and their directions showed changes after releases of both the anterior and posterior SS insertions and after the IS release. The results demonstrated (1) that the RC transmits SS muscle forces without diversion and (2) that RC releases do affect the strain field. Release of both heads of the SS led to statistically significant changes in strain magnitude and direction.</p>","PeriodicalId":54871,"journal":{"name":"Journal of Biomechanical Engineering-Transactions of the Asme","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145913653","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}

It is a mechanical barrier that supports the growing fetus. As pregnancy progresses, the cervix becomes more compliant and eventually opens in late pregnancy to facilitate childbirth. This dual function is facilitated by extensive remodeling of the cervical extracellular matrix (ECM), giving rise to its complex time-dependent material properties. Premature cervical remodeling is known to result in preterm birth, defined as birth before 37 weeks of gestation. While previous work has studied cervical remodeling using various biomechanical methods, it remains unclear how the intrinsic or flow-independent viscoelastic behavior of the cervix is influenced by cervical remodeling. In this study, an anisotropic reactive viscoelastic material model was formulated and investigated under tensile deformation to understand material behavior in cervical remodeling. To calibrate the model, experimental force relaxation data was used from uniaxial tension tests on Rhesus macaque cervical specimens from four gestational time points. The results showed that cervical tissue equilibrium and instantaneous stiffness significantly decreased from the nonpregnant (NP) to the late pregnancy status. In addition, cervical tissue in the late third trimester relaxed faster to equilibrium than the other gestational groups, particularly at prescribed grip-to-grip strains greater than 30%. This fast relaxation to equilibrium helps the cervix dissipate tensile hoop stresses induced by the fetus during labor, preventing its rupture.

In Part I of this study, a diaphyseal fracture finite element model for novel compliant plates is validated against experimental data with good agreement. In Part II, a parametric analysis is conducted using the validated model to characterize the performance of many compliant plate designs with varying geometry and materials. Under axial loading, all compliant plate configurations provided greater (1.03 mm versus 0.22 mm) and more symmetric (270-390%) axial interfragmentary motion than rigid plates. Steel compliant plates with thicker flexures (0.3-0.6 mm) may provide the best performance given their enhanced motion and comparable bending/torsional rigidity. In Part III, compliant plates are adapted for use in treating distal femur fractures. Results demonstrate that compared to a rigid plate, a compliant distal femur plate with increased thickness can effectively modulate interfragmentary motion-that is, increase the insufficient near cortex motion under low loads (from 0.14 mm to 0.23 mm) and reduce the excessive far cortex motion under large loads (from 7.96 mm to 2.54 mm).

Despite elastin providing fatigue and recoil properties in a variety of tissues such as vasculature and lungs, its role in tendon fatigue mechanics is largely unknown. Therefore, this study validated and leveraged a novel murine model of local elastin knockout in the limbs (Prx1Cre+; Elnfl/fl) to study the impacts of elastin on tendon stress relaxation, ramp to failure, and fatigue mechanics for functionally distinct Achilles tendons (ATs) and tibialis anterior tendons (TBs). Elastin knockout was confirmed via gene expression analysis, biochemical protein quantification, immunofluorescence confocal imaging, and analysis of 3D two-photon image stacks. Consistent with previous results of elastin reduction or disruption in ramp to failure mechanical testing, Prx1Cre+; Elnfl/fl ATs exhibited increased linear modulus; in contrast, TBs exhibited decreased linear modulus, demonstrating tendon-specific effects. In agreement with previous results, mechanical changes corresponded to alterations in dynamic alignment of collagen fibers, suggesting elastin can mediate collagen fiber orientation and recruitment. Furthermore, elastin knockdown led to increased strain during fatigue testing in ATs but increased early hysteresis and decreased fatigue-life in both tendon types. Damage metrics showed opposite trends for collagen denaturation by tendon type, but consistent results for kinking after fatigue loading. Results suggest different mechanisms underly each type of damage and that the impact of elastic fiber knockdown is tendon-dependent.</p>","PeriodicalId":54871,"journal":{"name":"Journal of Biomechanical Engineering-Transactions of the Asme","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12617611/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144979489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This principle relies on a robotic test system to move a biological joint to the same pose before and after transecting a ligament. The difference in joint forces before and after transecting the ligament is assumed to be the transected ligament's tension. However, the robotic test system's ability to accurately return the joint to the commanded pose is dependent on the compliance of the system's various components, which is often neglected. An alternative approach to superposition testing is to use additional sensors attached directly to the joint to inform robot motion. Accordingly, there are two objectives: (1) describe a testing methodology with 6DOF position sensors to correct for system compliance and (2) demonstrate the effectiveness of this methodology to reduce uncertainty of in situ forces determined using superposition. A Sensor Fusion algorithm fuses 6DOF position sensors with robot pose measurements to compensate for system compliance. For the equipment, loading condition, and surrogate knee joint used in this study, the Traditional control method underestimated ligament tension by 23% while the Sensor Fusion control method brought that error down to 3%.

However, the difficulty of validating lung deformation estimated by image registration has curbed widespread adoption in the clinic. In-silico images, reconstructed from finite element (FE) simulations, provide a method to verify the results estimated through image registration (IR). Our objective in this study was to use in-silico computed tomography (CT) images, reconstructed from FE simulations, to assess the accuracy of an image registration method. In this study, we used dynamic CT (4DCT) images from human patients to reconstruct the lungs and generate an FE mesh. In-silico simulations were performed using the lung FE mesh, and the results were used to generate in-silico dynamic CT images matching the resolution of the actual 4DCT images. Image registration was performed on the actual and in-silico images, and the results were compared to those from the FE simulation. Results indicated good agreement in displacement estimated by the FE simulations and the image registration of the actual and in-silico CT images. The difference in predicted displacement image registration of the actual CT images and the FE simulations was greatest at the main bronchi, with a value of 2.7 mm. This result highlighted the effectiveness of the FE simulation-based method to generate in-silico CT images. The volumetric strain comparisons between actual 4DCT and the in-silico images were used to assess the method's accuracy.
