BACKGROUND Flip-flops and sandals are popular choices of footwear due to their convenience. However, the effects of these types of footwear on lower extremity biomechanics are still poorly understood. Therefore, the objective of this study was to investigate differences in ground reaction force (GRF), center of pressure (COP) and lower extremity joint kinematic and kinetic variables during leve...

INTRODUCTION High vertical loading rates (VLR) of the ground reaction forces have been linked to increased risk of stress fractures when running [1]. Previous footwear research has shown that there are clear kinematic differences between shod, minimal and barefoot running conditions [2]. Moreover, it has been shown that these kinematic changes are coupled with altered loading rate patterns [2,3...

abstract older people enconter a reduced balance performance as they have lower sensory and motor abilities. balance problem pomote the risk of falling and subsequent disabling injuries and even death among older people.these problems can impose an extensive chargers on healthcare systems. insole and footwear are an interface between plantar surface and the ground and can regulate the sensory i...

We examine whether a firm’s debt maturity structure affects its credit quality. We find that firms with a larger proportion of their debt maturing within the year (short-term debt) are more likely to experience a severe fall in their credit quality in the following year, as measured by the severity of credit rating downgrades and the propensity to default. This effect is stronger for firms with...

The characteristics of the JT-60U detached divertor plasma in the SONIC simulation are investigated. With increasing mid-plane density, the electron temperature at the divertor decreases and the ion flux to the divertor plate increases. At higher densities, the temperature becomes less than 1 eV. However, rollover of the ion flux at the divertor plate, which is a characteristic of the detachmen...

Background The concept of instability footwear is to reduce stability, increase muscle activation and “tone”. Recently numerous brands have developed instability footwear for significant sales. Despite extensive marketing claims there are few empirical studies quantifying effects of instability footwear on muscle activity or motion in healthy individuals aside from Masai Barefoot Technology (MB...

A test program was conducted to determine the effectiveness of a seat belt restraint in preventing occupant movement in a rollover accident. A baseline type-2 seat belt (pelvic and torso restraint), and an improved type-2 seat belt restraint, both designed to restrict occupant motion in a rollover accident, were tested in a rollover restraints tester (RRT). Each seat belt was placed on a H-III ...

BACKGROUND Use of protective footwear before entering the intensive care units is enforced with the assumption that it lowers the incidence of bacterial floor colonization. The present study was carried out to find the efficacy of protective footwear on bacterial floor colonization. METHODS The study was carried out in the intensive care unit of a tertiary care hospital. The study was divided...

Maintaining postural stability is crucial, especially in hazardous occupational environments. The purpose of the study was to assess the role of three occupational footwear (low top shoe (LT); tactical work boot (TB) and steel-toed work boot (WB)) on postural stability when exposed to an occupational workload (4-h) involving standing/walking using the sensory organization test (SOT) equilibrium...

The present study examined whether a new footwear outsole with tread blocks and a hybrid rubber surface pattern, composed of rough and smooth surfaces, could increase slip resistance and reduce the risk of fall while walking on a wet floor surface. A drag test was performed to measure static and dynamic coefficient of friction (SCOF and DCOF, respectively) values for the footwear with the hybri...
