Flat foot is one of the common deformities in the youth population, seriously affecting the weight supporting and daily exercising. However, there is lacking of quantitative data relative to material selection and shape design of the personalized orthopedic insole. This study was to evaluate the biomechanical effects of material hardness and support height of personalized orthopedic insole on f...

Gait analysis using smart sensor technology is an important medical diagnostic process and has many applications in rehabilitation, therapy and exercise training. In this paper, we present a low power wireless smartshoe system to analyze different functional postures and characteristics of gait while walking. We have designed and implemented a smartshoe with a Bluetooth communication module to ...

We propose a novel polymer optical fiber (POF) sensing system based on fiber Bragg gratings (FBGs) to measure foot plantar pressure. The plantar pressure signals are detected by five FBGs, in the same piece of cyclic transparent optical polymer (CYTOP) fiber, which are embedded in a cork insole for the dynamic monitoring of gait. The calibration and measurements performed with the suggested sys...

To analyze plantar pressures during activities of daily living, one needs a fully portable system capable of measuring many steps over extended periods. This paper presents an inexpensive, reliable, portable plantar pressure acquisition system which we have developed. It allows the long-term recording (up to 2 hours) of pressure-time data from 14 pressure sensors within insoles. The sensor chos...

The use of custom-made insoles has shown to be effective for the treatment of high plantar pressure peak of patients with neuropathic feet. Objective: To observe the results of the usage of metatarsal plantar support type of insole in leprosy, through tests in gait and static posture with a baropodometric device. Ten patients with leprosy were randomly selected, ageing 25 to 60 years at the lep...

In this work, a fiber Bragg gratings (FBGs) based sensing insole, capable of simultaneously measure plantar force (PF) and shear (SF) is proposed. The insole has four measuring points, strategically located for full gait analysis. Each point contains sensor-cell which consists in polylactic acid (PLA) structure, covered by an epoxy resin layer, crossed one optical with two FBGs, FBG1 FBG2, resp...

Various foot complications can be easily avoided by continuously monitoring plantar (foot sole) pressure and temperature at home. Systems which simultaneously measure in real time are still scarce. In this work, the design, characterization, implementation of a Fiber Bragg Gratings (FBG) based smart insole capable measuring has been reported. The instrumented was tested verified during static g...

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...
