The basic premise central to the diagnosis and treatment of most mechanogenic foot and ankle pathologies is that a given foot will display a characteristic function depending on the biomechanical alignment of the hindfoot and forefoot. However, the effects of foot type on an individual's ability to perform comfortable cadence locomotion have not been(More)
Foot structure is typically evaluated using static clinical and radiographic measures. To date, the literature is devoid of a correlation between rearfoot frontal plane radiographic parameters and clinical measures of alignment. In a repeated-measures study comparing radiographic and clinical rearfoot alignment in 24 healthy subjects, radiographic angular(More)
INTRODUCTION Foot disorders are common among older adults and may lead to outcomes such as falls and functional limitation. However, the associations of foot posture and foot function to specific foot disorders at the population level remain poorly understood. The purpose of this study was to assess the relation between specific foot disorders, foot(More)
The relationship between the force generated by an isometrically contracting muscle and the associated myoelectric signal has been the subject of extensive investigation in the past and conflicting results were reported regarding this relationship. The objective of the present study was to investigate some of the sources that may lead to such conflicting(More)
The distributed vertical ground reaction forces were determined for a normative population and contrasted with data from subjects with flat feet. Nineteen asymptomatic subjects, 11 with a neutrally aligned foot type (normal arch) and 8 with a pes planus foot type (low arch), were studied as they walked barefoot across a pressure plate. The pressure plate(More)
BACKGROUND Making evidence-based decisions in the clinical management of gait dysfunction requires the ability to measure spatiotemporal gait variables validly and reliably. This study examined the accuracy, reliability, and validity of a clinical gait analysis system that is relatively inexpensive and portable, the GaitMat II (GM). METHODS The(More)
OBJECTIVE Foot pain is common, yet few studies have examined the condition in relationship to shoewear. In this cross-sectional study of men and women from the population-based Framingham Study, the association between foot pain and type of shoewear was examined. METHODS Data were collected on 3,378 members of the Framingham Study who completed the foot(More)
Many etiologies of tarsal tunnel syndrome exist, but it is difficult to determine the specific etiology for a patient. Surgical success rates vary in the literature from 44% to 100%. This retrospective study reviewed 40 patients with 45 data sets. Thirty-five patients (87.5%) in the study were female; 35 patients (87.5%) were caucasian. Thirty-two feet(More)
BACKGROUND Differences in foot structure are thought to be associated with differences in foot function during movement. Many foot pathologies are of a biomechanical nature and often associated with foot type. Fundamental to the understanding of foot pathomechanics is the question: do different foot types have distinctly different structure and function? (More)
This study was part of a long-term effort to develop a reliable diagnostic procedure for ankle ligament injuries. Earlier efforts led to the development and validation of a six-degrees-of-freedom instrumented linkage capable of measuring the flexibility characteristics of the ankle complex in vitro and in vivo. The major goal of the present study was to(More)
