Heel pressure ulcers are important clinical, humanitarian and economic problems arising in part from localized blood flow deficits during loading and inadequate flow recovery. Because there are few data available with regard to the intrinsic physiological responses of heel skin to pressure-induced ischaemia, the present study was undertaken to characterize the main features of the post-loading ...

A simple and rapid automatic method for detection of gait events at the foot could speed up and possibly increase the repeatability of gait analysis and evaluations of treatments for pathological gaits. The aim of this study was to compare and validate a kinematic-based algorithm used in the detection of four gait events, heel contact, heel rise, toe contact and toe off. Force platform data is ...

A common source of error when detecting heel-strike moments utilizing split force-plate treadmills is unwillingly stepping on contra-lateral force-plate. In this study, we quantified this error when heel-strike was detected based on such erroneous data and compared three methods to investigate how well the heel-strikes and stride-intervals were detected with erroneous data. Eleven subjects walk...

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...

BACKGROUND Excessive shoe heel abrasion is of concern to patients and shoe manufacturers, but little scientific information is available about this feature and its possible causes. The purpose of this study was to relate this phenomenon with biomechanical factors that could predispose to shoe heel abrasion. METHODS Ninety-seven recruits (median age 25) were enrolled in this study. Shoe abrasi...

Results The study group comprised 317 FMF patients (170 females, 147 males) with a mean age of 12.2 ± 5.7 years. The frequency of musculoskeletal complaints were as follows; arthritis 18%, arthralgia 43%, leg pain 43%, heel pain 36%, myalgia 8%, protracted arthritis 2%, protracted febrile myalgia 2%. Leg pain and heel pain were more frequently detected in patients with homozygous M694V (p<0.05)...
