Phase-locked dual-band vibration bursts strengthen anti-kindling by vibrotactile coordinated reset stimulation in a spiking network model

The paper shows that a dual-band vibration burst improves anti-kindling in a spiking network model compared to single-frequency stimulation.

Changes in peripheral sensory afference do not alter predictive motor planning: evidence from carpal tunnel syndrome

The paper examines whether anticipatory motor planning depends on peripheral sensory input by comparing ASA in carpal tunnel syndrome patients before and after surgery, finding no change in ASA despite improved sensory function.

Mechanical advantage is not invoked by additional cognitive load during multi-finger dexterous object manipulation

This study investigates whether increased cognitive load during multi-finger object manipulation triggers mechanical advantage force distribution, finding it does not.

Comparable neural and behavioural performance in dominant and non-dominant hands during grasping tasks

This study finds no significant difference in synergy index, EEG band power, or EEG-EMG coherence between dominant and non-dominant hands during grasping tasks.

Older individuals do not show task specific variations in EEG band power and finger force coordination

This study compares EEG band power and finger force coordination between young and older adults during two task conditions, finding no task-specific variations in older individuals.

Grasp context-dependent uncertainty alters the relative contribution of anticipatory and feedback-based mechanisms in object manipulation

This study investigates how uncertainty about grasp type during movement preparation affects the balance between feedback and feedforward mechanisms in object manipulation.

Kinematic signatures of fast feedback trajectory control during goal-directed finger, arm, and saccadic eye movements

The paper investigates whether goal-directed movements follow pre-planned trajectories or result from online control, finding evidence of early feedback control and varying controller gains during movements.

Role of post-trial visual feedback on unintentional force drift during isometric finger force production tasks

The paper investigates how post-trial visual feedback reduces unintentional force drift during isometric finger force tasks and identifies RC back coupling as the mechanism.

Distinct behavior of the little finger during the vertical translation of an unsteady thumb platform while grasping

The paper examines how the little finger contributes to object stabilization during thumb platform vertical translation, finding greater normal force changes in the little finger compared to the index finger.

Practice modifies the response to errors during a novel motor sequence learning task

This study shows that practice reduces the magnitude and duration of post-error slowing in a motor sequence learning task, even when overall performance plateaus.

Comparable behaviour of ring and little fingers due to an artificial reduction in thumb contribution to hold objects

This study tests the mechanical advantage hypothesis by reducing thumb contribution in a grip task, finding comparable normal forces between ring and little fingers.

Effort distribution changes effector choice, behaviour and performance: A visuomotor tracking study using finger forces

This study investigates how distributing mechanical effort between fingers affects motor performance in a visuomotor tracking task, finding that higher effort from dominant fingers improves performance.

Sensor location optimization and joint angle prediction in hand postures

The paper aims to predict joint angles from a reduced set of sensors for hand postures, using PCA-based sensor ranking for preliminary sorting.
