Single-leg landing (SL) is often associated with a high injury risk, especially anterior cruciate ligament (ACL) injuries and lateral ankle sprain. This work investigates the relationship between motion patterns (ankle initial contact angle [AICA] range of [AROM]) lower limb risk during SL, proposes an optimized strategy that can reduce risk. To more realistically revert simulate ACL mechanics, we developed knee musculoskeletal model reverts to nonlinear short-term viscoelastic mechanical...
This study aimed to verify the feasibility and short-term prognosis of prostatectomy without biopsy.
Objective The objective of this study was to evaluate the rotation and translation each joint in hindfoot compare load response healthy feet with that stage II posterior tibial tendon dysfunction (PTTD) flatfoot by analysing reconstructive three-dimensional (3D) computed tomography (CT) image data during simulated weight-bearing. Methods CT scans 15 PTTD were taken first a non-weight-bearing condition, followed full-body weight-bearing condition. images bones reconstructed into 3D models....
This study introduces a lightweight, multi-node IMU-based motion capture system optimized for biomechanical analysis, addressing limitations of traditional optical systems and challenges in sensor drift noise. Multi-node IMU offer distinct advantages such as portability, affordability, the ability to data real-world environments, making them particularly suited applications gait sports performance, rehabilitation. Enhanced calibration techniques correct biases accelerometers, gyroscopes,...
Patients with mechanic ankle instability experience increased tibiotalar and subtalar joint laxity. However, in vivo kinematics functional (FAI) patients lateral sprain (LAS) copers, especially during dynamic activities, are poorly understood. Ten FAI patients, 10 LAS healthy controls were included this study. A dual fluoroscopic imaging system was used to analyze the stair descent. Five key poses of descent analyzed. Kinematic data from six degrees freedom calculated utilizing a solid...
The motion of the distal syndesmosis correlates highly with instability, while an accurate kinematic description tibiofibular joint during normal gait has not previously been presented. Sixteen healthy syndesmoses sixteen living subjects (8 male and 8 female) were studied stance phase gait. Data CT scanning collected first used to create 3D models tibia fibula. lateral X-ray images captured by fluoroscopy when subject was walking. Seven key-pose selected for subsequent 2D bone model...
Aims This cross-sectional study aimed to investigate the in vivo ankle kinetic alterations patients with concomitant chronic instability (CAI) and osteochondral lesion of talus (OLT), which may offer opportunities for clinician intervention treatment rehabilitation. Methods A total 16 subjects CAI (eight without OLT eight OLT) healthy underwent gait analysis a stair descent setting. Inverse dynamic was applied ground reaction forces marker trajectories using AnyBody Modeling System....
Postoperative transfer metatarsalgia is a common complication after hallux valgus surgeries. Shortening of the first metatarsal traditionally thought to be primary cause it. However, we speculate abnormal loading pattern during gait real reason. This study determine specific differences in patterns between reconstructive (HV) feet with and without postoperative metatarsalgia, so as find risky characteristics this complication.Thirty were recruited pain group, while another 30 controls. All...
Abstract Background Current studies on how external perturbations impact gait dynamics have primarily focused the changes in body's center of mass (CoM) during treadmill walking. The biomechanical responses, particular to multi-planar hip joint coordination, following overground walking conditions are not completely known. Methods In this study, a customized gait-perturbing device was designed impose controlled lateral forces onto subject’s pelvis responses bilateral hips were simulated by...
ABSTRACT Objective Diabetic foot ulcer (DFU) is a severe complication with high mortality. High plantar pressure and poor microcirculation are considered main causes of DFU. The specific aims were to provide novel technique for real‐time measurement skin blood flow (SBF) under walking‐like stimulus delineate the first metatarsal head dynamic characteristics because life‐like loading conditions in healthy individuals. Methods Twenty young participants (14 male 6 female) recruited. baseline...
Simulated patient systems play a crucial role in modern medical education and research, providing safe, integrative learning environments enabling clinical decision-making simulations. Large Language Models (LLM) could advance simulated by replicating conditions patient-doctor interactions with high fidelity low cost. However, ensuring the effectiveness trustworthiness of these remains challenge, as they require large, diverse, precise knowledgebase, along robust stable knowledge diffusion...
Studies have yet to determine the optimal height at which posterior tibial tendon (PTT) can be re-routed and length discrepancy different levels in terms of PTT transfer via circumtibial route. This cadaveric study was conducted subcutaneous compare discrepancies heights. Twenty-five fresh normal lower legs were used for measurements. exposed then isolated. An incision along calf made re-route outside fascia. The upper edge classified as point "a." distal tip "b." midpoints intermediate...
