Exploring student-athletes’ perceptions of their psychological readiness to return to sport following a concussion
(American Psychological Association, 2022-08-16)
Athletes returning to sport following a concussion are deemed “ready” once they progress through the return to sport (RTS) steps. However, this process largely overlooks psychological factors involved in returning to sport. ...
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 muscle activation strategies differ when lifting or lowering a load
(Springer, 2020-08-14)
Purpose
Lowering a load could be associated with abnormal shoulder and scapular motion. We tested the hypothesis that lowering a load involves different shoulder muscle coordination strategies compared to lifting a ...
Lower trapezius weakness and shoulder complex biomechanics during the tennis serve
(Lippincott, Williams and Wilkins, 2019-07-02)
Purpose
This study aimed to assess the effect of lower trapezius (LT) weakness on humeral and scapular kinematics and shoulder muscle activity during the tennis serve.
Methods
Fifteen competitive male tennis players ...
An optimization method tracking EMG, ground reactions forces and marker trajectories for musculo-tendon forces estimation in equinus gait
(Frontiers Media, 2019-07-16)
In the context of neuro-orthopedic pathologies affecting walking and thus patients' quality of life, understanding the mechanisms of gait deviations and identifying the causal motor impairments is of primary importance. ...
Sex differences in glenohumeral muscle activation and coactivation during a box lifting task
(Taylor and Francis, 2019-07-19)
Manual material handling is associated with shoulder musculoskeletal disorders, especially for women. Sex differences in glenohumeral muscle activity may contribute to women’s higher injury risk by affecting shoulder load ...
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 ...
Surrogate optimization of a lattice foot orthotic
(Elsevier, 2022-11-30)
Background:
Additive manufacturing enables to print patient-specific Foot Orthotics (FOs). In FOs featuring lattice structures, the variation of the cell’s dimensions provides a locally variable stiffness to meet the ...
