The aim of this study was to quantify the effects of heel-forefoot height on ankle kinematics during locomotion in children. Measurements were taken by a motion capture system and a force plate on five children. They were asked to perform standing, walking, jogging and sidestepping in barefoot, low heel, standard heel and high heel shoe conditions. Results showed that rearfoot plantarflexion an...

AIM To examine the reproducibility of crown-heel length measurement; the precision and reproducibility of knee-heel length measurement; and the association between the two in healthy preterm infants. METHODS Paired crown-heel and knee-heel lengths were measured on 172 occasions by three observers in 43 preterm infants between 205 and 458 days of postconceptional age. RESULTS Crown-heel leng...

This study investigated the effects of shoe heel height on the rollover characteristics of the biologic ankle-foot system. Ten nondisabled adult female volunteers walked using three pairs of shoes with varying heel heights and at three walking speeds with each pair of shoes. Kinematic and kinetic data needed to calculate the rollover shapes of the ankle-foot systems of the participants were col...

INTRODUCTION Chronic post-anoxic myoclonus, also known as Lance-Adams syndrome, may develop following hypoxic brain injury, and is resistant to pharmacological therapy. CASE REPORT The patient we presented developed post-anoxic action myoclonus with severe, completely incapacitating myoclonic jerks. Myoclonus did not respond to the treatment with commonly used agents, i.e. valproate and clona...

BACKGROUND The bilateral heel-rise test is an instrument that evaluates the performance of the triceps surae. Normative parameters need to be established for the use of the heel-rise test in clinical practice. OBJECTIVE To determine the reference values for the bilateral heel-rise test. METHODS This cross-sectional study assessed healthy subjects using the bilateral heel-rise test. We analy...

Heel pressure ulcers (PU) are a major concern in orthopedic patients. A prospective 6-month study was conducted in an acute care hospital in Canada to determine the incidence of heel PU in an orthopedic population, evaluate the effect of patient and care variables on heel PU incidence, and describe the natural history/sequelae of Stage I heel PU. One hundred and fifty (150) patients (average ag...

[Purpose] This study aimed to analyze the effect of heel pads in ankle-foot orthoses on dynamic motion aspects of gait in stroke patients from the viewpoint of energy conversion efficiency. [Subjects] Fourteen chronic stroke patients who were ambulatory and had lower extremity motor function categorized as Brunnstrom stage IV participated in the study. [Methods] A three-dimensional motion analy...

Heel strike detection is an important cue for human gait recognition and detection in visual surveillance since the heel strike position can be used to derive the gait periodicity, stride and step length. We propose a novel method for heel strike detection using a gait trajectory model, which is robust to occlusion, camera view, and low resolution. When a person walks, the movement of the head ...

Although wearing high-heeled shoes has long been considered a risk factor for the development for patellofemoral pain (PFP) in women, patellofemoral joint kinetics during high-heeled gait has not been examined. The purpose of this study was to determine if heel height increases patellofemoral joint loading during walking. Eleven healthy women (mean age 25.0±3.1 yrs) participated. Lower extremit...

BACKGROUND Management of large and deep heel ulcers (LDHUs) is a challenge in patients with diabetic foot lesions. We assessed outcomes of a treatment protocol to save feet with LDHUs from amputation. METHODS We managed LDHUs (larger than 3 cm(2)) in diabetic feet using a multidisciplinary approach consisting of medical and surgical management, including revascularization and amputation, if n...
