This study investigates how asymmetric gait affects intersegmental coordination during walking perturbations, finding that segment-level coordination varies while whole-body dynamics remain stable.

This study shows that wearing rigid foot soles improves balance during beam walking, but does not transfer to improved performance with bare feet, suggesting a mechanical rather than neural effect.

This paper validates a gait task, the turning and barrier course, for detecting freezing of gait and measuring the efficacy of deep brain stimulation in Parkinson's disease.

This study uses wearables to measure mobility performance in hemodialysis patients, finding differences between cognitive-intact and cognitive-impaired groups that suggest mobility metrics could serve as digital biomarkers for cognitive impairment.

This paper predicts TUG scores from gait characteristics using video analysis and machine learning, showing effective results and interpretable associations.

This study examines age and Parkinson’s disease effects on corticospinal control during walking, finding reduced low beta band coherence and altered gait timing in older and PD participants.

This study finds that Parkinson’s disease patients have impaired perception of whole-body motion during balance perturbations, which correlates with worse balance ability.

This study identifies abnormal antagonist muscle activity as a biomarker for falls in Parkinson's disease by showing its correlation with CoM motion and fall frequency.

This study examines how arm swing amplitude and lower-limb asymmetry affect gait stability in healthy adults using split-belt treadmill walking.

This study examines how balance control is affected by single versus successive stimulation of different sensory systems, finding that successive stimulation leads to greater balance destabilization.

This study examines how walking speed affects gait variability in healthy adults and those with bilateral vestibulopathy, finding that specific parameters distinguish between groups and within-group abilities.

The paper identifies three balance mechanisms used during walking and shows how they are coordinated to maintain upright balance.

This study shows older adults can transfer gait adaptation improvements from one leg to the untrained leg after repeated perturbations, despite slower recovery initially.

The paper presents a model showing how ankle stiffness and spinal sensorimotor gains coadapt to maintain balance during neural delays, with implications for aging and balance strategies.

This study applies the free-energy principle to human postural control, showing that skin stretch feedback reduces postural sway entropy in simulated sensory deficit conditions.

This study compares walking muscle synergies between individuals with mild and severe slipping to identify differences in baseline motor control patterns that may predict fall risk.

The paper presents a feature selection approach for fall-risk classification using static force-plate data, finding that optimal features were insufficient for reliable classification due to limited sensitivity to high-risk subjects.

The paper identifies a clinical phenotype in Parkinson's disease patients that predicts early development of postural instability and cognitive decline.

This study shows that the nervous system optimizes energy cost to determine preferred step width during walking, but does so incompletely, suggesting trade-offs with other objectives.

This study shows elderly fallers can achieve balance recovery similar to non-fallers by adjusting posture in anticipation of perturbations.

This paper quantifies increased antagonist leg muscle activity during reactive balance responses in Parkinson’s disease patients, linking it to disease severity and balance ability.

The paper compares the Goalkeeper Game (GG) and MoCA tests for predicting gait performance in Parkinson's disease patients, finding GG has slightly better predictive power.
