Assessing the effects of foot strike patterns and shoe types on the control of leg length and orientation in running.

This research investigates the stabilization of leg length and orientation during the landing phase of running, examining the effects of different footwear and foot strike patterns. Analyzing kinematic data from twenty male long-distance runners, both rearfoot and forefoot strikers, we utilized the Uncontrolled Manifold approach to assess stability. Findings reveal that both leg length and orientation are indeed stabilized during landing, challenging the hypothesis that rearfoot strikers exhibit less variance in deviations than forefoot strikers, and that increased footwear assistance would reduce these deviations.

Overground gait adaptability in older adults with type 2 diabetes in response to virtual targets and physical obstacles.

Background: To step over an unexpected obstacle, individuals adapt gait; they adjust step length in the anterior-posterior direction prior to the obstacle and minimum toe clearance height in the vertical direction during obstacle avoidance. Inability to adapt gait may lead to falls in older adults with diabetes as the results of the effects of diabetes on the sensory-motor control system. Therefore, this study aimed to investigate gait adaptability in older adults with diabetes.

Effects of diabetes mellitus on step length and minimum toe clearance adaptation.

Background: Adaptive gait involves the ability to adjust the leading foot in response to the requirement of dynamic environments during walking. Accurate adjustments of the minimum toe clearance (MTC) height and step length can prevent older people from falling when walking and responding to hazards. Although older people with diabetes fall more frequently than healthy older adults, no previous studies have quantified their adaptive gait abilities.

Insight into the hierarchical control governing leg stiffness during the stance phase of running.

Leg stiffness plays a key role in the storage and release of elastic energy during stance. However, the extent to which a runner is able to reuse stored energy remains a limiting factor in determining their running effectiveness. In this study, ten habitual rearfoot strikers and ten habitual forefoot strikers were asked to run on a treadmill in three footwear conditions: traditional, neutral, and minimal running shoes.

The Allergen Bureau VITAL Program.

This paper sets out the role of the Allergen Bureau and the Voluntary Incidental Trace Allergen Labelling (VITAL) Program from its origin in 2007 to its current iteration, VITAL 2. Herewith are outlined the scientific principles that support the program; the program's application in the food chain; and the benefits of the program's use to the food industry, clinicians, and the allergic consumer. VITAL was developed by the Australian and New Zealand food industry in consultation with multiple stakeholders, including consumer organizations, industry bodies, regulators, and retailers, to provide a standardized, science-based risk assessment process for the investigation of the potential presence of food allergens due to cross-contact and to determine whether, for cases in which the allergen is unable to be removed or controlled consistently, precautionary statements are required.

Prediction of foot clearance parameters as a precursor to forecasting the risk of tripping and falling.

Tripping and falling is a serious health problem for older citizens due to the high medical costs incurred and the high mortality rates precipitated mostly by hip fractures that do not heal well. Current falls prevention technology encompasses a broad range of interventions; both passive (e.g.

Investigating scale invariant dynamics in minimum toe clearance variability of the young and elderly during treadmill walking.

Current research applying variability measures of gait parameters has demonstrated promise for helping to solve one of the "holy grails" of geriatric research by defining markers that can be used to prospectively identify persons at risk of falling . The minimum toe clearance (MTC) event occurs during the leg swing phase of the gait cycle and is a task highly sensitive to the spatial and balance control properties of the locomotor system. The aim of this study is to build upon the current state of research by investigating the magnitude and dynamic structure from the MTC time series fluctuations due to aging and locomotor disorder.
