Skeletal-level control-based forward dynamic analysis of acquired healthy and assisted gait motion
(Springer, 2018-07-09)
[Abstract]
Gait analysis is commonly addressed through inverse dynamics. However, forward dynamics can be advantageous when descending to muscular level, as it allows that activation and contraction equations are integrated ...
Do Muscle Synergies Improve Optimization Prediction of Muscle Activations During Gait?
(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 ...
Using Accelerometer Data to Tune the Parameters of an Extended Kalman Filter for Optical Motion Capture: Preliminary Application to Gait Analysis
(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, ...
Lower Back Injury Prevention and Sensitization of Hip Hinge with Neutral Spine Using Wearable Sensors during Lifting Exercises
(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 ...
Assessment of Methods for the Real-Time Simulation of Electronic and Thermal Circuits
(MDPI, 2020-03)
[Abstract] Time–domain simulation of electronic and thermal circuits is required by a large array of applications, such as the design and optimization of electric vehicle powertrain components. While efficient execution ...
Assessment of Linearization Approaches for Multibodydynamics Formulations
(2017-07)
[Abstract] Formulating the dynamics equations of a mechanical system following a multibody dynamics approach often leads to a set of highly nonlinear Differential Algebraic Equations (DAEs). While this form of the equations ...
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
(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 ...
Behaviour of Augmented Lagrangian and Hamiltonian Methods for Multibody Dynamics in the Proximity of Singular Configurations
(2016-04)
[Abstract] Augmented Lagrangian methods represent an efficient way to carry out the forward-dynamics simulation of mechanical systems. These algorithms introduce the constraint forces in the dynamic equations of the system ...
Editorial of Special Issue Combining Sensors and Multibody Models for Applications in Vehicles, Machines, Robots and Humans
(MDPI, 2021-09)
[Abstract] The combination of physical sensors and computational models to provide additional information about system states, inputs and/or parameters, in what is known as virtual sensing, is becoming more and more popular ...
Applying a muscle fatigue model when optimizing load-sharing between muscles for short-duration high-intensity exercise: A preliminary study
(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 ...
