BACKGROUND Foot orthoses are often used to treat lower limb injuries associated with excessive pronation. There are many orthotic modifications available for this purpose, with one being the medial heel skive. However, empirical evidence for the mechanical effects of the medial heel skive modification is limited. This study aimed to evaluate the effect that different depths of medial heel skive...

Congenital flat foot is a rare condition. In a special clinic for foot deformities only one case was found in 121 patients (Osmond-Clarke 1956). Adequate correction depends on recognition of the deformity within a few weeks of birth, and any child presenting with a rigid, dorsiflexed and everted forefoot should be regarded as having congenital flat foot until careful clinical and radiological e...

Purpose: The present study investigated the most appropriate footprint index and its related parameters for the diagnosis of flatfoot, especially in cases with mild deformity. Methods: In total, 148 footprints were recorded from 77 young women with flatfoot. Footprints were classified into three groups of mild, moderate, and sever. Footprint indexes included Sztriter-Godunov (KY), Clarke’s Ang...

The mechanics of the modern human foot and its specialization for habitual bipedalism are well understood. The windlass mechanism gives it the required stability for propulsion generation, and flattening of the arch and stretching of the plantar aponeurosis leads to energy saving. What is less well understood is how an essentially flat and mobile foot, as found in protohominins and extant apes,...

If humanoid robots are to be used in society, they should be able to maintain their balance. Knowing where to step is crucially important. In this paper we contribute an algorithm that can compute the foot step location such that bipedal balance is maintained for planar bipeds with point feet and an arbitrary number of non‐massless links on a horizontal and ...

A technique of distributed surface electrical stimulation of the foot sole was used to elicit the withdrawal reflex in ankle flexors and extensors during gait. Tibialis anterior and soleus reflexes were recorded from 8 subjects during treadmill walking. The largest responses in tibialis anterior were evoked at the arch of the foot, while in soleus the largest responses were elicited at the heel...

BACKGROUND A number of multi-segment foot protocols have been proposed to obtain measurements of clinical value. In the clinical assessment of foot pathologies and deformities, such as in the pes-planus, the frontal-plane alignment of the calcaneus and the dynamic properties of the medial longitudinal arch are critical parameters though often neglected by the majority of foot protocols. The aim...

Introduction: Unilateral secondary flat-foot in children is unusual, and in the absence of a major trauma history should raise suspicion of a neuromuscular etiology. Flatfoot from tibialis posterior tendon (TPT) rupture in children is very rare. Case Report: A 10-year-old girl presented with unilateral flatfoot and unusual shoe wear of few years duration. A TPT rupture was diagnosed. After obse...
