Optimality equivalence and computational advantages of free-floating base dynamics compared to full-body dynamics
(Elsevier, 2022-12-19)
Several transcription methods exist for predictive simulations of free-floating base motions like athlete performing twisting somersaults. Following a brief overview of the literature, we proposed two original direct ...
Effect of expertise on shoulder and upper limb kinematics, electromyography, and estimated muscle forces during a lifting task
(SAGE, 2020-11-25)
Objective
To highlight the working strategies used by expert manual handlers compared with novice manual handlers, based on recordings of shoulder and upper limb kinematics, electromyography (EMG), and estimated muscle ...
Shoulder electromyography-based indicators to assess manifestation of muscle fatigue during laboratory-simulated manual handling task
(Taylor and Francis, 2021-08-14)
Muscle fatigue is a risk factor for developing shoulder musculoskeletal disorders. The aim of this study was to identify shoulder electromyographic indicators that are most indicative of muscle fatigue during a laboratory ...
Bow-side kinematics studies in violinists : an experimental design tracking intra- and -inter-musician variability by bow stroke’s type, string played and tempo
(Science and Medicine, Inc., 2022-09-01)
Comparison of bow-side kinematics in violinists is hindered by the
scarcity of studies available. This makes meta-analysis impossible. This
paper assesses the effect of music-based variables (bow stroke, tempo and
string ...
Optimal 3D arm strategies for maximizing twist rotation during somersault of a rigid-body model
(Springer, 2020-10-07)
Looking for new arm strategies for better twisting performances during a backward somersault is of interest for the acrobatic sports community while being a complex mechanical problem due to the nonlinearity of the dynamics ...
Bioptim, a python framework for musculoskeletal optimal control in biomechanics
(Institute of Electrical and Electronics Engineers, 2022-06-28)
Musculoskeletal simulations are useful in
biomechanics to investigate the causes of movement disorders,
to estimate non-measurable physiological quantities
or to study the optimality of human movement. We introduce
Bioptim, ...
