Muscle activation and electromyography studies

Functional and Structural Moment Arm Validation for Musculoskeletal Models: A Study of the Human Forearm and Hand

The paper validates and scales musculoskeletal models of the human forearm and hand using posture-dependent moment arms, isometric force measurements, and error detection to improve accuracy in torque prediction.

Coordination amongst quadriceps muscles suggests neural regulation of internal joint stresses, not simplification of task performance

The paper examines muscle co-variation in rats during locomotion, finding that co-variation patterns suggest neural regulation of internal joint stresses rather than simplification of task performance.

Head MagnetoMyography (hMMG): a novel approach to monitor face and whole-head muscular activity

This paper introduces head magnetomyography (hMMG) to monitor whole-head muscular activity, demonstrating its ability to decode stimulus valence and detect previously neglected neck muscle activity.

Sensitivity of the paired motor unit analysis for estimation of motoneuron excitability to commonly used constraints and filters

This study evaluates how different computational parameters affect the {Delta}F technique for estimating motoneuron excitability using paired motor unit analysis.

Information decomposition of multichannel EMG to map functional interactions in the distributed motor system

This study uses information decomposition of EMG data to analyze functional interactions between muscles during postural tasks, revealing task-dependent changes in neural networks.

A Comprehensive Mathematical Model of Surface Electromyography and Force Generation

This paper presents a comprehensive mathematical model of surface EMG and force generation in skeletal muscles, integrating previous models and demonstrating its ability to reproduce physiological effects and generate synthetic data.

Noncontractile tissue forces mask muscle fiber forces underlying muscle spindle Ia afferent firing rates in stretch of relaxed rat muscle

The paper shows that history-dependent muscle spindle Ia afferent firing rates in relaxed rat muscle mirror muscle fiber forces, which are masked by noncontractile tissue forces.

The cost of being stable: Trade-offs between effort and stability across a landscape of redundant motor solutions

The paper explores trade-offs between muscular effort and limb stability in muscle activation patterns across individuals, finding that small increases in effort significantly improve stability.

Fatigue influences the recruitment, but not structure, of muscle synergies

This study examines how fatigue affects muscle synergy recruitment but not structure during upper limb movements using EMG data and non-negative matrix factorization.

Gravitational and dynamic components of muscle torque underlie tonic and phasic muscle activity during goal-directed reaching.

This study examines how gravitational and dynamic muscle torque components relate to static and phasic muscle activity during reaching movements.
