Using radiographs and diagrams, this article reviews the most commonly used axes and angles of the foot, including: longitudinal axis of the rearfoot, collum tali axis, talocalcaneal angle, cuboid abduction angle, longitudinal axis of the lesser tarsus, lesser tarsus angle, talonavicular angle, longitudinal axis of the metatarsus, forefoot adductus angle, metatarsus adductus angle, first interm...

the analytic signal for magnetic anomalies was initially defined as a “complex field deriving from a complex potential” (nabighian, 1972). this function can be computed easily in the frequency domain, its real part is the horizontal derivative of the field and its imaginary part is the vertical derivative. analytic signal processing and interpretation requires few initial assumptions regarding ...

BACKGROUND Neuropathic deformities impair foot and ankle joint mobility, often leading to abnormal stresses and impact forces. The purpose of our study was to determine differences in radiographic measures of hind foot alignment and ankle joint and subtalar joint motion in participants with and without neuropathic midfoot deformities and to determine the relationships between radiographic measu...

The Visual Magnitude Satellite Catalogue effort [1] presently employs a simple straight-line model for solar phaseand declination-angle dependencies, an approach that, at least for declination angle, lacked any real pedigree. The present attempt to improve the modeling began by investigating several competing gridding techniques that would allow two-parameter brightness dependencies to be displ...

Devonian and Carboniferous paleoArmorican to the central European Variscan strucmagnetic data from the European Hercynides show a rural trend (Figure 1) and its potential imporcoherent pattern in inclination but significant tance for geodynamics is only one aspect of this dispersion in declination. The declination anomaplate tectonic enigma. The bending around the Bay lies with respect to expec...

Recent studies comparing terrestrial versus aquatic locomotion in animals have shown that changes in kinematics, muscular activation patterns, and performance across media are often dramatic. Surprisingly, however, despite the importance of feeding to the survival of most animals, few studies have compared differences in feeding behaviour between media. The present study compares prey-capture b...

The purpose of this study was to investigate the mechanism of foot strike pattern (FSP) adaptations to a minimalist shoe among the different heel height in running. We found that the strike index (SI) and foot strike angle (FSA) were systematically affected by changes in heel height. We also observed a linear correlation between FSA and SI. However, no changes in initial foot angle (IFA) were f...

the analytic signal method is a semiautomatic method for estimating the location of causative bodies in magnetic and gravity methods. the application of analytic signal for interpretation of two dimensional (2d) structures was introduced by nabighian (1972). the analytic signal is defined as a complex function in which the real and imaginary parts are a pair of hilbert transforms. in other word...
