Alterations in motor modules and their contribution to limitations in force control in the upper extremity after stroke [PDF]
Frontiers in Human Neuroscience, 2022 The generation of isometric force at the hand can be mediated by activating a few motor modules. Stroke induces alterations in motor modules underlying steady-state isometric force generation in the human upper extremity (UE).

How to Decide the Number of Gait Cycles in Different Low-Pass Filters to Extract Motor Modules by Non-negative Matrix Factorization During Walking in Chronic Post-stroke Patients [PDF]
Frontiers in Human Neuroscience, 2022 The motor modules during human walking are identified using non-negative matrix factorization (NNMF) from surface electromyography (EMG) signals. The extraction of motor modules in healthy participants is affected by the change in pre-processing of EMG ...

Generalizability of motor modules across walking-based and in-place tasks – a distribution-based analysis on total knee replacement patients [PDF]
Frontiers in Bioengineering and BiotechnologyIntroduction: There are evidences that the nervous system produces motor tasks using a low-dimensional modular organization of muscle activations, known as motor modules.

A Pathological Condition Affects Motor Modules in a Bipedal Locomotion Model [PDF]
Frontiers in Neurorobotics, 2019 Bipedal locomotion is a basic motor activity that requires simultaneous control of multiple muscles. Physiological experiments suggest that the nervous system controls bipedal locomotion efficiently by using motor modules of synergistic muscle ...

Motor modules account for active perception of force [PDF]
Scientific Reports, 2019 Despite longstanding evidence suggesting a relation between action and perception, the mechanisms underlying their integration are still unclear. It has been proposed that to simplify the sensorimotor integration processes underlying active perception ...

Muscle Synergy Analysis of a Hand-Grasp Dataset: A Limited Subset of Motor Modules May Underlie a Large Variety of Grasps [PDF]
Frontiers in Neurorobotics, 2018 Background: Kinematic and muscle patterns underlying hand grasps have been widely investigated in the literature. However, the identification of a reduced set of motor modules, generalizing across subjects and grasps, may be valuable for increasing the ...

INA complex liaises the F1Fo-ATP synthase membrane motor modules [PDF]
Nature Communications, 2017 The inner membrane assembly complex (INAC) interacts with components of the F1F0-ATP synthase but its function remains unclear. Here the authors show that INAC associates with two distinct complexes during F1F0-ATP synthase formation, which points ...
