Article Abstract
Objectives: Reactive stepping is necessary to prevent falls when a person slips or trips while walking, particularly in outdoor activities. Individuals with stroke usually exhibit reactive balance impairment. Trunk training is effective for improving balance and mobility after stroke; however, its effect on reactive stepping remains unknown. This study aimed to examine the effects of trunk training on reactive stepping in community-dwelling individuals after stroke.
Methods: This study was conducted using an A-B-A single-subject design. Two community-dwelling women with chronic stroke (79 years old, 9 years post-stroke and 83 years old, 17 years post-stroke) participated in this study. The baseline (A) and intervention (B) phases lasted for 6 weeks. Specifically, the participants did not receive any intervention in phase A, whereas they performed home-based trunk training in phase B. Outcome measures included the foot-off time, maximum trunk rotation angular velocity, number of steps during forward reactive stepping following perturbation, and Trunk Impairment Scale (TIS) score.
Results: Decreased trunk rotation and step count corresponding to improved TIS score were observed in one case after the intervention. However, trunk control did not improve in the other case after the intervention, and reactive stepping kinematics remained unchanged.
Conclusions: Enhancing trunk control may improve reactive stepping in individuals with chronic stroke; nevertheless, further evidence is required.

Stroke significantly contributes to long-term disability, one of the problems is with impaired balance control, increasing the risk of falls. The risk of falls may be mitigated using reactive balance training (RBT) which has been shown to effectively reduce fall risk by enhancing reactive stepping following repeated balance perturbations. However, the optimal RBT intensity for people with chronic stroke remains unknown.

Titanium dioxide (TiO) is one of the most extensively studied oxides as an active catalyst or catalyst support, particularly in energy and environmental applications, but the atomistic mechanisms governing its dynamic response to reactive environments and their correlation to reactivity remain largely elusive. Using in situ environmental transmission electron microscopy (ETEM), synchrotron X-ray diffraction (XRD), ambient-pressure X-ray photoelectron spectroscopy (AP-XPS), temperature-programmed reduction (TPR), reactivity measurements, and theoretical modeling, we reveal the dynamic interplay between oxygen loss and replenishment of anatase TiO under varying reactive conditions. Under H exposure, anatase TiO undergoes surface reduction via lattice oxygen loss, forming TiO.

Background: Perturbation balance training (PBT) is an effective regime that reduces fall rates by triggering and improving balance recovery skills. Controlling trunk movements consistently reflects effective reactive stepping, as it enhances proximal stability, providing a stable base for limb movements.
Objective: To demonstrate the effect of PBT during seated hands-free stationery cycling on objective balance parameters of reactive and proactive balance control in standing.

Background: Reactive balance (quick motoric responses to an external balance challenge) and affective characteristics are linked to falls and negatively impacted in people with multiple sclerosis (MS). While previous studies indicate a potential link between these outcomes, little work has systematically evaluated these relationships, particularly in people with MS. The goal of this study was to assess the association between reactive balance and affect in people with MS, and whether fall-status moderates this relationship.
