Summary: Production of functional forces by human motor systems requires coordination across multiple muscles. This study investigated intermuscular coordination for grip and pinch at different force levels using a novel method called multiplex recurrence networks (MRN). The results showed differences in network parameters between grasp types and force levels, with extrinsic muscles exhibiting higher muscle coupling than intrinsic muscles.

Summary: The study examines the contribution of peripheral fingers in object stabilization when rotational equilibrium is disturbed. Results show that the change in normal force of the little finger due to downward thumb translation is significantly greater than the change in normal force of the index finger due to upward translation, possibly due to morphological correlations between the thumb and little finger during thumb displacement.

Summary: Adding mass affects human movement and alters lower limb muscle activities. This study investigated the influence of added mass on lower limbs by analyzing kinematics, muscle activities, and energy consumption. The results showed that with increased mass, muscle activation and joint torque increased, stride time decreased, and energy expenditure raised correspondingly. Overall, participants adjusted their muscle activities and movement patterns in response to added mass, indicating a relationship between energy consumption and added mass.

Summary: The study utilized a dual-task paradigm to investigate the effects of attentional control on gait and inter-joint coordination, revealing significant differences in performance between the High Attentional Control (HAC) group and the Low Attentional Control (LAC) group. This suggests that the ability of young adults to maintain gait control and modulate inter-joint coordination patterns in response to gait disturbances is influenced by their level of attentional control.

Summary: This study investigated forearm muscle activity and wrist angular displacement during wrist perturbations, and found an inverse relationship between grip force and angular displacement, a decrease in time to peak displacement with increased grip force, and an increase in muscle activity with higher grip forces, with greater muscle activity in ulnar deviation compared to radial deviation.

Summary: In this study, the influence of gravity on isometric force control was examined. It was found that gravity creates an illusion that upward forces are larger than downward forces of the same magnitude. Additionally, gravity also affects the control of grip force. These findings have implications for the design of haptic devices to be used during flight or space activities.

Summary: This study systematically reviewed the literature on human-human handover actions, where at least one of the behavioral data (kinematics or grip force) was measured. Nine relevant studies were identified and their different methodologies and results were described. Based on these results, a common framework was suggested to comprehensively and clearly describe handover actions, which includes categorizing actors as giver and receiver, and dividing the action into four phases.

Summary: Contrary to the predictions of feedforward internal model-based control theory, strong, precise anticipatory grip force control was observed during manipulations of a complex object, suggesting the need for an alternative theoretical framework to explain anticipatory grip force control.

Summary: This pilot study utilized the Linear Fit Method to compare the gait of stroke survivors with a healthy baseline in terms of walking speed. The results showed significant linear relationships between walking speed and the variations in the hemiparetic gait pattern. As walking speed increased, certain aspects of the gait pattern became more similar to the healthy comparison, while others remained different. These findings demonstrate how joint kinematics can be used to identify and quantify effective compensatory hemiparetic gait patterns.

Summary: This study aimed to evaluate the sensitivity of different symmetry metrics to asymmetry effects. The results showed that not all commonly used discrete symmetry metrics are equally sensitive to reference effects of asymmetry. Future studies should consider selecting the most sensitive metric in their analyses to avoid underpowered research.

Summary: This study investigated the association between time-varying measures of physical function and survival in men and women aged 70 years and older. The findings showed that higher gait speed was associated with increased survival in women, but there was no significant effect of gait speed on survival in men, or grip strength on survival in women or men.

Summary: Studies suggest that supplementary tactile feedback for hand prostheses may not provide significant functional benefits, possibly due to confounding factors and limitations in experimental design. Even with rich, high-bandwidth acoustic feedback, relevant grasping information was not effectively provided in the experiments.

Summary: For patients undergoing reverse total shoulder arthroplasty (RTSA), limited shoulder abduction is associated with the glenohumeral joint contribution, not scapulothoracic mobility. Good to excellent shoulder abduction requires increasing postoperative abduction strength and improving the glenohumeral joint contribution.

Summary: This study identified coordination deficits in children with cerebral palsy compared to typically developing children, but similar poor levels of stability in both groups. The addition of leg movements negatively impacted coordination and stability for all children. While coordination between the arms improved post-intervention, stability did not improve for either group.

On the other hand, unfamiliar music cues increased gait velocity and familiarity, but did not enhance enjoyment or decrease cognitive demand.

Summary: Older adults consume more metabolic energy during walking than younger individuals, possibly due to a redistribution of leg muscle demand. Modulating propulsive forces in younger adults affects metabolic and joint power costs, with increased hip joint power having a significant impact on metabolic energy expenditure.

Summary: Individuals with Parkinson's disease demonstrated impaired interlimb coordination, particularly between the more affected arm and legs, during backward walking compared to healthy controls. This may contribute to difficulties in walking for those with Parkinson's disease, highlighting the importance of understanding and addressing coordination deficits in rehabilitation strategies.

Summary: This study investigated the effects of visual information on locomotor adaptation and retention by comparing incremental levels of visual occlusion. The results showed that participants with complete visual occlusion displayed less consistency in their walking pattern compared to those with lower visual field occlusion. However, varying levels of visual occlusion did not significantly affect locomotor adaptation or retention.

Summary: The ability to adapt walking speed is crucial for independent mobility, and this ability diminishes with age. This study examined the biomechanical parameters during transitions from preferred walking speed to slower or faster walking in older and younger adults. The findings showed distinct changes in step length, hip flexion, and dorsiflexion during the transition, as well as altered timing of peak joint angles in older adults. This study provides important insights into the kinematics of walking speed transitions in different age groups.
