A Fair and EMG‑Validated Comparison of Recruitment Criteria, Musculotendon Models and Muscle Coordination Strategies, for the Inverse‑Dynamics Based Optimization of Muscle Forces During Gait
Michaud, Florian; Lamas, Mario; Lugrís-Armesto, Urbano; Cuadrado, Javier (BioMed Central Ltd., 2021-01)[Abstract] Experimental studies and EMG collections suggest that a specific strategy of muscle coordination is chosen by the central nervous system to perform a given motor task. A popular mathematical approach for solving ... -
Applying a muscle fatigue model when optimizing load-sharing between muscles for short-duration high-intensity exercise: A preliminary study
Michaud, Florian; Frey-Law, Laura A.; Lugrís-Armesto, Urbano; Cuadrado, Lucía; Figueroa-Rodríguez, Jesús; Cuadrado, Javier (Frontiers, 2023-04)[Abstract] Introduction: Multiple different mathematical models have been developed to represent muscle force, to represent multiple muscles in the musculoskeletal system, and to represent muscle fatigue. However, incorporating ... -
Comparison of Several Muscle Modeling Alternatives for Computationally Intensive Algorithms in Human Motion Dynamics
Lamas, Mario; Mouzo, Francisco; Michaud, Florian; Lugrís-Armesto, Urbano; Cuadrado, Javier (Springer, 2022-04-05)[Abstract] Several approaches are currently employed to address the predictive simulation of human motion, having in common their high computational demand. Muscle modeling seems to be an essential ingredient to provide ... -
Determination of the 3D Human Spine Posture from Wearable Inertial Sensors and a Multibody Model of the Spine
Michaud, Florian; Lugrís-Armesto, Urbano; Cuadrado, Javier (MDPI, 2022)[Abstract] Determination of spine posture is of great interest for the effective prevention, evaluation, treatment and evolution monitoring of spinal disorders. Limitations of traditional imaging systems, including cost, ... -
Do Muscle Synergies Improve Optimization Prediction of Muscle Activations During Gait?
Michaud, Florian; Shourijeh, Mohammad S.; Fregly, Benjamin J.; Cuadrado, Javier (Frontiers Media S. A., 2020-07)[Abstract] Determination of muscle forces during motion can help to understand motor control, assess pathological movement, diagnose neuromuscular disorders, or estimate joint loads. Difficulty of in vivo measurement made ... -
Energy Expenditure Estimation During Crutch-Orthosis-Assisted Gait of a Spinal-Cord-Injured Subject
Michaud, Florian; Mouzo, Francisco; Lugrís-Armesto, Urbano; Cuadrado, Javier (Frontiers Media SA, 2019)[Abstract] Determination of muscle energy expenditure by computer modeling and analysis is of great interest to estimate the whole body energy consumption, while avoiding the complex character of in vivo experimental ... -
Lower Back Injury Prevention and Sensitization of Hip Hinge with Neutral Spine Using Wearable Sensors during Lifting Exercises
Michaud, Florian; Pérez Soto, Manuel; Lugrís-Armesto, Urbano; Cuadrado, Javier (MDPI, 2021-08)[Abstract] The popularization and industrialization of fitness over the past decade, with the rise of big box gyms and group classes, has reduced the quality of the basic formation and assessment of practitioners, which ... -
Neuromusculoskeletal Human Multibody Models for the Gait of Healthy and Spinal-Cord-Injured Subjects
Michaud, Florian (2020)[Abstract] Spinal-cord-injured (SCI) subjects with some level of hip actuation but with no or very weak actuation at knee and ankle levels can often walk with the assistance of knee-ankle-foot orthoses (KAFO) and crutches. ... -
Using Accelerometer Data to Tune the Parameters of an Extended Kalman Filter for Optical Motion Capture: Preliminary Application to Gait Analysis
Cuadrado, Javier; Michaud, Florian; Lugrís-Armesto, Urbano; Pérez Soto, Manuel (MDPI, 2021-02)[Abstract] Optical motion capture is currently the most popular method for acquiring motion data in biomechanical applications. However, it presents a number of problems that make the process difficult and inefficient, ...
