This study examines age-related differences in balance control during walking under visual perturbations, finding older adults show reduced self-motion estimation accuracy but some adaptation capacity.

The paper compares stabilization mechanisms in standing and walking using a lumped model, finding task-level organization of stabilization with consistent position-velocity gain ratios.

This study examines how balance training in older adults affects cortico-muscular functional connectivity during postural recovery, finding training-induced changes in beta-band coherence with muscle synergies.

This study investigates how mediolateral foot placement is controlled after perturbations affecting linear or angular momentum, finding that linear momentum primarily governs foot placement.

This study shows that linear and angular momentum are simultaneously controlled in human walking, explaining correlations between ground reaction forces and center of mass/pressure positions.

This study examines how different visual perturbations affect balance control during walking, finding that specific perturbations alter foot placement and center of mass trajectories in humans.

This study shows that people with Parkinson's Disease have greater foot placement errors during walking compared to healthy older adults, suggesting impaired coordination between center of mass and foot placement.

This study examines corticospinal excitability during mediolateral gait instability and finds increased excitability in upper-leg muscles but not lower-leg muscles during destabilized treadmill walking.

This paper develops and validates an open-source neural network algorithm for recognizing daily-life gait in older adults using lower-back inertial sensors, showing high accuracy in both internal testing and external validation.

This study compares foot placement control during overground and treadmill walking, finding differences in stability mechanisms and precision.

This study examines how head orientation affects vestibular signal modulation of paraspinal muscle activity during walking, finding reduced coherence and gain in leftward head orientation.

This tutorial presents methods to assess stabilizing feedback control of human walking using gait analysis, ranging from simple kinematics to inverse dynamics, with open-source code provided.

The paper models human walking stability by combining biomechanics and neural control, showing that stable walking requires specific control gain values that depend on walking speed.

This paper uses machine learning to predict motor evoked potential (MEP) presence from TMS setup parameters, achieving up to 90% accuracy within subjects.

This study examines cortical representation overlap between hand and forearm muscles using navigated TMS and finds greater overlap in synergistic muscle pairs.

This study examines how vestibular stimulation affects gait stability and foot placement precision across different step widths.

This study shows that including non-MEP points in TMS mapping can affect estimates of cortical motor areas, suggesting conventional methods may overestimate excitability regions.

This study examines how balance improves in older adults after one and ten balance training sessions, finding rapid gains in robustness but slower performance improvements and no significant changes in reflexes or co-contraction.

The paper identifies an ankle strategy during steady-state walking where ankle moments correct for foot placement errors and influence subsequent foot placement.

This study shows that vestibular contributions to gait vary with stabilization demands, not just gait stability, as evidenced by changes in coherence and local dynamic stability during different walking conditions.

This study shows that long-term balance training improves feedback control of perturbed balance in older adults by altering muscle activation patterns.

The paper investigates how foot placement and ankle moments contribute to gait stability during walking under different constraints.

This study examines how older adults adjust gait stability to different walking conditions and whether balance training affects these adjustments, finding no training-induced improvements.

This study examines how different arm swing amplitudes affect the cost of transport during walking, finding that excessive arm swing does not further reduce energy costs.
