Summary: Flatfoot is a risk factor for patellofemoral pain syndrome (PFPS), and running with flatfoot can lead to greater coordination asymmetry and variability compared to running with a normal foot, particularly during midstance. These differences may help explain the association between flatfoot and PFPS, but further prospective studies incorporating additional factors are necessary to fully understand the relationship between flatfoot and running injuries like PFPS.

Summary: Comparison of lower-extremity intra-joint coordination and its variability between fallers and non-fallers older adults during gait showed significant differences in spatiotemporal gait parameters and joint coordination patterns. Fallers exhibited lower cadence, walking speed, and stride length but greater double support and stride time than non-fallers. Differences in segment coordination and its variability suggest potential adaptations resulting from decreased efficiency and inconsistencies in neuromuscular control, indicating reduced ability to generate power during the push-off phase in fallers.

Summary: This study found that a high variance in segmental configurations destabilizing the CoM in the vertical direction was related to future falls, suggesting that UCM analysis variables can be useful for evaluating fall risk.

Summary: This study proposes and validates a virtual reality implementation of moving visual scene experiments to assess sensory integration mechanisms underlying balance control. The results demonstrate that this approach can quantitatively evaluate balance deficits and provide a simplified experimental platform.

Summary: This study investigates the effect of vibrotactile stimulation of the hallux nail on segmental coordination to control center of mass (CoM) movement in the mediolateral direction during walking. The results show that vibrotactile stimulation is more effective for young individuals with larger motor noise and smaller synergy index during the single-stance phase.

Summary: This study examined the cortical response to sensory and mechanical perturbations in older adults while standing and investigated the relationship between cortical activation and postural control. The results showed that older adults had significantly higher relative beta power at cortical areas related to postural control under sensory and mechanical perturbations. Additionally, as task difficulty increased, young adults had increased relative beta band power while older adults demonstrated decreased relative beta power.

Summary: This study systematically investigated the actions of main lower limb muscles on the sagittal-plane angular kinematics of the hip, knee, and ankle joints during upright standing and gait. The observed muscle actions on crossed and non-crossed joints were phase- and task-specific.

Summary: The study investigates the effect of postural instability on the use of kinematic redundancy to stabilize finger and center-of-mass trajectories during reaching from standing in healthy adults. The results show that postural instability reduces the ability to use kinematic redundancy, and the central nervous system may prioritize postural stability over focal movement.

Summary: This study aimed to determine the relationship between joint coordination variability and knee pain severity and joint loading. The results showed that joint coordination variability may influence knee pain and joint loading, suggesting that movement coordination of the hip, knee, and ankle should be considered in the clinical management and future research related to knee osteoarthritis.

Summary: The act of gazing downward, instead of solely being used for guiding locomotion, can also contribute to postural control by providing more appropriate visual information. Studies have shown that downward gaze just a few steps ahead resulted in steadier standing and walking posture which suggests an interplay between visual information used for locomotion and postural control.

Summary: In individuals with lower limb loss, hip, knee, and ankle joint motions influence postural sway during standing balance. Specifically, increasing intact-side hip flexion, knee extension, and ankle plantarflexion motion increases postural sway. With vision removed, a re-weighting of lower limb joint sensory mechanisms may control postural sway, indicating a potential increase in fall risk.

Summary: This study investigated the effects of nGVS on lower limb muscle activity and joint angular velocity using inertial measurement units and surface electromyography. The results revealed that nGVS altered physical responses in different standing postural conditions. Further research is needed to explore specific muscle activities and joint motion parameters.

Summary: The study aimed to validate a predictive model for standing posture, joint torques, and support forces for smartphone users, and propose risk scales based on simulations for musculoskeletal disorders prevention. The model was able to accurately estimate posture and reaction forces, providing estimates for a wide range of environmental conditions based on user body mass index. Joint torques risk scales, especially for shoulder and elbow, were constructed to characterize the risks incurred by users.

Summary: In healthy older adults, there are changes in alpha power and theta/beta power ratio during dual-task standing. The change in theta/beta power ratio in particular may be related to the ability to regulate standing postural control when simultaneously performing unrelated, attention-demanding cognitive tasks.
