In this paper, a novel fiber-optic sensing system based on fiber Bragg gratings (FBGs) to measure foot plantar pressure is proposed. This study first explores the Pedar-X insole foot pressure types of the adult-size chart and then defines six measurement areas to effectively identify four foot types: neutral foot, cavus foot, supinated foot and flat foot. The plantar pressure signals are detect...

The purpose of the study was to describe the relationship between foot placement angle, arch type, and rearfoot motion during running. Twenty women were filmed in the frontal plane at 100 fps. Subjects displaying a variety of foot placement angles were chosen. Before data collection, arch indices were calculated. Each subject ran five trials at a pace of 3.5 m/sec. All subjects wore the same ty...

In the adult a painful rigid flat foot with a calcaneo-navicular bar usually requires treatment by triple arthrodesis. In the adolescent also, long-standing deformity or adaptive joint changes may call for triple arthrodesis to alleviate pain. In the younger patient, however, without adaptivejoint changes, it is worth considering simple excision ofthe calcaneo-navicular bar. This has been pract...

OBJECTIVES The purpose of this study was to examine the correlation between the foot arch volume measured from static positions and the plantar pressure distribution during walking. METHODS A total of 27 children, two to six years of age, were included in this study. Measurements of static foot posture were obtained, including navicular height and foot arch volume in sitting and standing posi...

Introduction Investigations of the calcaneocuboid joint typically find that it is among the least mobile of the intrinsic foot joints [1]. When movement is found, it is shown to be highly variable among individuals [2]. The joint is therefore relegated to the presumably rigid lateral aspect of the foot. The complementary articular surfaces of the two relevant bones are both relatively flat, wit...

Traditionally tibialis Posterior Insufficiency is still considered the commonest cause of acquired adult flat foot. This is still considered as the primary cause and has influenced both treatment and the diagnosis of the condition. Foot surgeons are now questioning the whole classification and the fundamental errors within this that have not been challenge for over 30 years. In this review arti...
