Common methods to investigate the effectiveness of insoles include finite element method and experimental approach. However, most finite element research has focused on the two-dimensional plantar fascia stresses during static standing with insoles, rather than those of three-dimensional plantar fascia. Furthermore, the effects of insole with design parameters (metatarsal pad, toe pad, and arch support) on dynamic plantar pressures still need further exploration. Therefore, this study aimed to quantify the impact of custom-made insoles on foot biomechanics by combining both methods. Finite element method was employed to evaluate stress on the plantar fascia and bony structures when static standing, both barefoot and with a custom-made insole. Furthermore, 10 participants were recruited to investigate dynamic plantar pressures during walking barefoot and with insole. The relative time of four subphases during stance phase, total contact time, peak plantar pressure (Peak P), and pressure time integral (PTI) were assessed. Finite element results revealed reduced plantar fascia stresses and more uniform stress distribution over metatarsals and phalanges when standing with insole. Additionally, Peak P and PTI values in the second and third metatarsals were significantly lower when walking with insole. With the presence of insole, Peak P and PTI values in medial regions were significantly reduced, except for the midfoot region. In conclusion, custom-made insole with the addition of a metatarsal pad, toe pad, and arch support can effectively distribute foot tissue stress evenly, alleviate plantar pressure, and thus prevent pain.","PeriodicalId":20666,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine","volume":"239 4","pages":"360-369"},"PeriodicalIF":1.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144034145","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, training outside the operating room is limited by the lack of portability and high cost of high-fidelity simulators. The aim of this study is to present the ArthSim hybrid simulator, a low-cost portable device for the training of psychomotor skills of orthopaedic surgeons in arthroscopic knee surgery. The ArthSim simulator consists of a physical model of the knee with an integrated motion tracking system with a virtual reality application that captures and replicates the movements of the knee joint and the two arthroscopic instruments inside the virtual model, in a mixed reality approach to arthroscopy training. The functionality of ArthSim's technology was evaluated in two experiments: static and dynamic. The interaction of the physical knee joint and the arthroscopic instruments within the virtual model was evaluated by eight orthopaedic surgeons, who recreated the common positions of the knee, arthroscope, and instruments during the exploration of the internal structures. The results indicated a surgical total workspace of 80 mm3 with a range of motion of 115° for flexion, 23° for abduction, and 33° for rotation in the knee joint. The measurements showed linearity and repeatability with errors below, for motion capture. Feedback provided by orthopaedic surgeons on ArthSim was used to identify the device's points of improvement. The ArthSim simulator provides an effective alternative for arthroscopic training in a hybrid simulation approach, offering natural haptics to enhance the surgical experience of orthopaedic surgeons.","PeriodicalId":20666,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine","volume":" ","pages":"398-410"},"PeriodicalIF":1.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143754312","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}

This ex vivo study evaluated the success rate and procedure time of three instrument retrieval techniques - Masserann, microsonic, and loop techniques - under the visualization of dental operation microscope (DOM) assisted by an endoscope. Sixty extracted human mandibular single-rooted teeth with simulated fractures were assigned to the Masserann, microsonic, or ultrasonic with loop techniques (n = 20/group), each performed under endoscopic visualization alongside DOM. The success rate of instrument removal and procedure time were recorded. Complications, such as root perforation, apical extrusion and secondary fracture, were recorded. Statistical analysis was conducted using Pearson χ2 and Kruskal-Wallis tests with 5% significance threshold. Success rates for the microsonic, Masserann, and ultrasonic with loop techniques were 80%, 70%, and 80%, respectively (p > 0.05). The average procedure times were 13.02 min for the microsonic technique, 17.25 min for the Masserann technique, and 17 min for the ultrasonic with loop technique (p > 0.05). The Masserann technique demonstrated a higher complication rate, with two cases each of perforation and apical extrusion, whereas no secondary fractures occurred in any group. Conclusively, the microsonic technique showed the highest success rate with the shortest retrieval time, indicating its efficiency and suitability for instrument removal from root canals, particularly when combined with enhanced visualization through endoscopy.","PeriodicalId":20666,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine","volume":"239 4","pages":"381-387"},"PeriodicalIF":1.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144050583","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 success of AF ablation depends on the adhesion of the catheter to the tissue. Existing electrical coupling index (ECI) and electrode-interface resistance (IR) methods based on impedance measurement to evaluate the adhesion between catheters and tissues do not explore the internal changes of the tissue during the compression process. This study introduces a new method to understand these internal changes using multi-frequency impedance combined with Cole-Cole model fitting, which is critical for accurate characterization of the contact between catheter and tissue. We used four-electrodes impedance measurement, using customized circuits and compression platform, applying 5-400 g (3.6-228.2 Pa) pressure to the bullfrog thighs to collect impedance data at frequencies of 500-100 kHz. The Cole-Cole model was then used for data fitting and analysis. The customized circuit accurately detects impedance up to 2 kΩ with less than 5% amplitude error, less than 15% phase error, and less than 6% error in model component values. Correlation analysis showed a significant linear relationship between extracellular fluid resistance and applied pressure (Pearson R ≈ 0.9, p < 0.05), indicating that extracellular fluid resistance increases with compression. This suggests that there is a significant linear positive correlation between the extracellular fluid resistance and the applied pressure, meaning that as the pressure increases, the extracellular fluid resistance correspondingly rises. This may provide a new perspective for studying the degree of catheter-tissue contact during atrial fibrillation ablation procedures.","PeriodicalId":20666,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine","volume":"239 4","pages":"370-380"},"PeriodicalIF":1.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144041877","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}

Firstly, the simulation model of soft tissue indentation experiment was established to obtain the mechanical response under continuous loading condition. The mechanical response of kindy tissue under discontinuous loading was obtained by the actual indentation experiment. Secondly, the mechanical response is predicted and the influence of loading parameters on the prediction accuracy is analyzed. The mechanical response under continuous loading was obtained by simulation, and the mechanical response under non-continuous loading was obtained by indentation experiment. The proposed advanced prediction method is verified by the obtained mechanical responses. The results show that the proposed method can predict the mechanical response of soft tissue well.

The novelty of the work stems from its integration of deep learning with a robotics platform for identifying emotional pragmatics deficits. In this study, the proposed methodology utilizes the implementation of machine and DL-based classification techniques, which have been applied to a collection of open-source datasets to identify audio emotions. The application of pre-processing and converting audio signals of different emotions utilizing Mel-Frequency Cepstral Coefficients (MFCC) resulted in improved emotion classification. The data generated using MFCC were used for the training of machine or DL models. The trained models were then tested on a randomly selected dataset. DL has been proven to be more effective in the identification of emotions using robotic structure. As the data generated by MFCC is of a single dimension, therefore, one-dimensional DL algorithms, such as 1D-Convolution Neural Network, Long Short-Term Memory, and Bidirectional-Long Short-Term Memory, were utilized. In comparison to other algorithms, bidirectional Long Short-Term Memory model has resulted in higher accuracy (96.24%), loss (0.2524 in value), precision (92.87%), and recall (92.87%) in comparison to other machine and DL algorithms. Further, the proposed model was deployed on the robotic structure for real-time detection for improvement of social-emotional pragmatic responses in individuals with deficits.

As cases increase, there is an urgent need for alternative treatments, especially for severe POP, where options remain limited. Surgical procedures involving synthetic meshes are associated with several complications, leading to the FDA (Food and Drug Administration) banning the commercialisation of these meshes to treat cases of transvaginal prolapse. Biodegradable meshes offer a potential solution to address the drawbacks associated with synthetic meshes, offering improved biocompatibility and biomechanical properties.This study developed computational models with variations in pore geometry, pore size, filament thickness and the inclusion of filaments in specific regions of the mesh. One of the meshes was then 3D printed to validate the simulation results. Subsequently, a uniaxial tensile test was performed on sow vaginal tissue to compare its mechanical behaviour with the simulations and identify meshes that closely mimic vaginal tissue behaviour. The mesh that most closely replicates vaginal tissue behaviour featured a smaller pore diameter (1.50 mm), filaments placed in specific areas, and variable filament thickness across the mesh. However, when compared to the uterosacral ligament, the meshes did not exhibit similar mechanical properties. Additionally, the commercially available mesh failed to replicate the behaviour of both vaginal tissue and the uterosacral ligament, suggesting it may not be the optimal option for POP repair. Biodegradable meshes, with their customisable properties, show great promise as future solutions for personalised and safer surgical treatment of POP.","PeriodicalId":20666,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine","volume":"239 3","pages":"294-307"},"PeriodicalIF":1.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143977741","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}
