BACKGROUND This pilot study aimed to assess the differences in center of pressure trajectory in neuropathic patients with steppage gait. Steppage gait has previously been evaluated by several biomechanical methods, but plantar pressure distribution has been much less studied. The purpose of this study was to analyze the changes in center of pressure trajectory using a force plate. METHODS The...

The insole shape and the resulting plantar stress distribution have a pivotal impact on overall health. In this paper, by Finite Element Method, maximum stress value and stress distribution of plantar were studied for different insoles designs, which are the flat surface and the custom-molded (conformal) surface. Moreover, insole thickness, heel's height, and different materials were used to mi...

This work presents the development of a portable, wireless activity monitoring system for the estimation of biomechanical gait parameters. The system uses a pair of instrumented insoles able to measure pressure from different points of the foot including four commercial piezoresistive pressure sensors and a three-axis accelerometer, all together integrated in the insole to determine foot forces...

This study aimed to use the plantar pressure insole for estimating the three-dimensional ground reaction force (GRF) as well as the frictional torque (T(F)) during walking. Eleven subjects, six healthy and five patients with ankle disease participated in the study while wearing pressure insoles during several walking trials on a force-plate. The plantar pressure distribution was analyzed and 10...

There is limited evidence on the efficacy of insole materials to reduce plantar pressure during regular walking and loaded walking. In-shoe pressures subjective footwear comfort were recorded in twenty healthy participants at a self-selected treadmill speed six conditions: two commercial insoles or no insole, with without carrying load backpack. A single-material comprised polyurethane, had red...

OBJECTIVE The aim of this study was to investigate the effect of shoe design on the plantar pressure dynamics of patients with diabetic neuropathy during walking. RESEARCH DESIGN AND METHODS Three shoe design categories were tested. Total contact area and biomechanical variables in multiple areas under the foot were measured. RESULTS Shoes with a rocker bottom principle reduced pressure 35-...

BACKGROUND Age-related loss of foot-sole cutaneous sensation is very common and is associated with impaired balance control. This study investigated the effect of a balance-enhancing insole (designed to facilitate foot-sole sensation) on lateral gait stability and evaluated its effectiveness in daily life. METHODS Forty community-dwelling older adults (age 65-75) with moderate loss of foot-so...

Methods Ten healthy older people with a pronated foot posture (age 67.1± 5.5 years) and sixteen healthy elderly with normal foot posture (age 67.1± 5.9 years) were recruited. The Foot Posture Index (FPI) was used to determine pronated and normal foot posture. Static balance in double limb stance was assessed using Kistler force plate measures during four shod conditions: 1) 5° medial heel and f...

The main purpose of this study was to investigate the effect of arch support insoles on uphill and downhill walking of persons with flatfoot. Sixteen healthy college students with flatfoot were recruited in this study. Their heart rate, peak oxygen uptake (VO2), and median frequency (MDF) of surface electromyogram were recorded and analyzed. Nonparametric Wilcoxon signed-rank test was used for ...

The past decade has seen the emergence of numerous new wearable devices, including many that have been widely adopted by both physicians and consumers. In this paper, we discuss design application smart insoles to measure gait plantar pressure. Herein, investigate potential applications with fewer sensing spots consequent reduction in amount data acquired from feet. main purpose is influence la...
