A Sensorized 3D-Printed Knee Test Rig for Preliminary Experimental Validation of Patellar Tracking and Contact Simulation.

Experimental validation of computational simulations is important because it provides empirical evidence to verify the accuracy and reliability of the simulated results. This validation ensures that the simulation accurately represents real-world phenomena, increasing confidence in the model's predictive capabilities and its applicability to practical scenarios. The use of musculoskeletal models in orthopedic surgery allows for objective prediction of postoperative function and optimization of results for each patient.

Four-compartment muscle fatigue model to predict metabolic inhibition and long-lasting nonmetabolic components.

Computational muscle force models aim to mathematically represent the mechanics of movement and the factors influencing force generation. These tools allow the prediction of the nonlinear and task-related muscle behavior, aiding biomechanics, sports science, and rehabilitation. Despite often overlooking muscle fatigue in low-force scenarios, these simulations are crucial for high-intensity activities where fatigue and force loss play a significant role.

Use of patellofemoral digital twins for patellar tracking and treatment prediction: comparison of 3D models and contact detection algorithms.

Poor patellar tracking can result in painful contact pressures, patella subluxation, or dislocation. The use of musculoskeletal models and simulations in orthopedic surgeries allows for objective predictions of post-treatment function, empowering clinicians to explore diverse treatment options for patients. Although a promising approach for managing knee surgeries, the high computational cost of the Finite Element Method hampers its clinical usability.

Adaptation and validation of the muscle dysmorphic disorder inventory in a population of French athletes (MDDI-Fr).

Introduction: Muscle dysmorphia, a theme mainly investigated by Anglo-Saxon research, is a specific body dysmorphic disorder that characterizes individuals who think they are insufficiently muscular and lean. Understudied in francophone countries, tools translated and validated in French to measure the symptomatology of muscle dysmorphia remain rare.

Objectives: The aim of this study was the translation into French and the psychometric validation of a tool evaluating muscle dysmorphia, the Muscle Dysmorphic Disorder Inventory (MDDI-Fr), through 13 items divided into three dimensions: the "Drive For Size" (DFS), the "Appearance Intolerance" (AI) and the "Functional Impairment" (FI).

The Use of Wearable Inertial Sensors and Workplace-Based Exercises to Reduce Lateral Epicondylitis in the Workstation of a Textile Logistics Center.

People whose jobs involve repetitive motions of the wrist and forearm can suffer from lateral epicondylitis, which is a significant burden on both the individual and the employer due to treatment costs, reduced productivity, and work absenteeism. This paper describes an ergonomic intervention to reduce lateral epicondylitis in the workstation of a textile logistics center. The intervention includes workplace-based exercise programs, evaluation of risk factors, and movement correction.
