Novel Safety Floors Attenuate Impact Differentially across Extreme Bmi Groups

چکیده
INTRODUCTION Novel safety flooring systems (SFs) show promise as an intervention to reduce fall-related injuries in seniors [1]. However, the protective capacity of SFs has never been assessed using experimental impact tests with humans. Furthermore, the influence of body mass index (BMI) on the protective capacity of SFs is unknown. Mechanically, soft tissue acts as a shock absorber by decreasing system stiffness and absorbing energy during impact [2]. Since soft tissue thickness over the greater trochanter [3] has shown to vary with BMI, SFs might have a differential protective capacity for people of different BMI. The purpose of this study was to test the hypotheses that: 1) SFs would provide greater impact attenuation when compared to institutional vinyl or carpet; 2) SFs-related impact attenuation would be greater for low BMI individuals.

Energy absorption during impact on the proximal femur is affected by body mass index and flooring surface.
Impact mechanics theory suggests that peak loads should decrease with increase in system energy absorption. In light of the reduced hip fracture risk for persons with high body mass index (BMI) and for falls on soft surfaces, the purpose of this study was to characterize the effects of participant BMI, gender, and flooring surface on system energy absorption during lateral falls on the hip with...
متن کاملQuantification of the trade-off between force attenuation and balance impairment in the design of compliant safety floors.
Safety floors (also known as compliant floors) may reduce the risk of fall-related injuries by attenuating impact force during falls, but are only practical if they do not negatively affect balance and mobility. In this study, we evaluated seven safety surfaces based on their ability to attenuate peak femoral neck force during simulated hip impacts, and their influence on center of pressure (CO...
متن کاملThe influence of novel compliant floors on balance control in elderly women--A biomechanical study.
Novel compliant floors aim to decrease the risk for fall-related injury by providing substantial force attenuation during the impact phase of falls. Certain models of compliant flooring have been shown to have limited influence on postural sway and successful completion of dynamic balance tasks. However, the effects of these products on balance recovery mechanisms following an externally induce...

Introduction: The relation between patient Body Mass Index (BMI) and the external dose rate of thyroid cancer patients treated with 131I has been investigated. Methods: A total of 183 patients treated with 131I were selected randomly and divided according to their administrated activity into three groups: 3.7GBq, 5.5GBq and 7.4GBq. They were also stratified into three gro...
متن کاملPreventing Deaths and Injuries of Fire Fighters Working Above Fire-Damaged Floors
Fire fighters are at risk of falling through fire-damaged floors. Fire burning underneath floors can significantly degrade the floor system with little indication to fire fighters working above. Floors can fail within minutes of fire exposure, and new construction technology such as engineered wood floor joists may fail sooner than traditional construction methods. NIOSH recommends that fire fi...
