Gradient optimization of multi-layered density-graded foam laminates for footwear material design
2020, Journal of BiomechanicsCitation Excerpt :The properties of materials used in therapeutics shoes play a starring role in the effectiveness and the success of the footwear in satisfying clinical and biomechanical requirements. The characteristics of the utilized materials, including cushioning stiffness, have been directly linked to the biomechanics of redistribution and reduction of plantar loads during, for example, running or walking (Nicolopoulos et al., 2000; Healy et al., 2010; Chatzistergos et al., 2017; Giandolini et al., 2020). The need for effective cushioning is imperative for maximizing the pressure redistribution and reduction.
Optimised cushioning in diabetic footwear can significantly enhance their capacity to reduce plantar pressure
2020, Gait and PostureCitation Excerpt :What is not clear however is how soft or how stiff they should be, and which parameters are important for defining their optimum stiffness. This gap in knowledge is reflected onto clinical practice too where material selection is still based on empirical or anecdotal evidence [9,10]. A finite element analysis aiming to provide some initial insight on optimum cushioning indicated that appropriate selection of material stiffness in footwear could significantly improve their pressure relieving capacity [11].
Dynamic rheological comparison of silicones for podiatry applications
2018, Journal of the Mechanical Behavior of Biomedical MaterialsCitation Excerpt :An important part of the features of foot ortoses depends on the material of which they are made. Pathology, age and weight are important factors to choose the right type of orthoses and the material of which they are made (Nicolopoulos et al., 2000). Interactions between the foot and the insole/shoe have been studied but more studies are still needed to clarify the biomechanical effects of such devices (Chen et al., 2010).
Evaluation of the pressure-redistributing properties of prefabricated foot orthoses in older people after at least 12 months of wear
2011, Gait and PostureCitation Excerpt :Although a survey in Australia indicated that podiatrists were six times more likely to prescribe customised orthoses over prefabricated orthoses [10], several recent studies have indicated that prefabricated orthoses may be equally effective as customised devices in the treatment of some foot conditions [11–13]. A potential limitation of many prefabricated foot orthoses is that they are generally constructed using soft or semi-rigid materials that deform more readily than the more rigid materials typically used for customised foot orthoses [14,15]. Consequently, the biomechanical effects of prefabricated orthoses may be lost as the material fatigues [16,17].
Manufacturing methodology for personalised symptom-specific sports insoles
2009, Robotics and Computer-Integrated ManufacturingCitation Excerpt :While there are contradictions over classification methods, there is a general agreement between professionals with regard to the important physical characteristics within orthotic fabrication. These include their response to temperature, elasticity, hardness, density, durability, flexibility, compressibility and resilience [16,31]. Density and hardness are of particular interest as it is these attributes that affect the impact attenuation of the device; a high-density material will have little cushioning and so will provide a rigid, often controlling structure whereas a material of low density will absorb shock.
