BACKGROUND: Unstable sole designs have been used as functional or therapeutic tools for improving body stability during locomotion. It has been suggested that the narrow base of support under the feet generate perturbations that challenge the instability of different joints during motion, thereby forcing the body to modify its movement in order to maintain a stable gait. The purpose of the present study was to explore the correlation between the stability of the footwear-device and the magnitude of perturbation conveyed during gait...

[Purpose] The aim of this study was to determine the effect of application of a metatarsal bar on the pressure in the metatarsal bones of the foot using a foot analysis system (pressure on the forefoot, midfoot, and rearfoot). [Subjects and Methods] Forty female university students in their twenties were selected for this study, and an experiment was conducted with them as the subjects, before and after application of a metatarsal bar. The static foot regions were divided into the forefoot, midfoot, and rearfoot, and then the maximum, average, and low pressures exerted at each region were measured, along with the static foot pressure distribution ratio...

BACKGROUND/METHODOLOGY: Ankle arthrodesis is one popular surgical treatment for ankle arthritis, chronic instability, and degenerative deformity. However, complications such as foot pain, joint arthritis, and bone fracture may cause patients to suffer other problems. Understanding the internal biomechanics of the foot is critical for assessing the effectiveness of ankle arthrodesis and provides a baseline for the surgical plan. This study aimed to understand the biomechanical effects of ankle arthrodesis on the entire foot and ankle using finite element analyses...

There is evidence to suggest being overweight or obese places adults at greater risk of developing foot complications such as osteoarthritis, tendonitis and plantar fasciitis. However, no research has comprehensively examined the effects of overweight or obesity on the feet of individuals older than 60 years of age. Therefore we investigated whether foot pain, foot structure, and/or foot function is affected by obesity in older adults. Three hundred and twelve Australian men and women, aged over 60 years, completed validated questionnaires to establish the presence of foot pain and health related quality of life...
