BACKGROUND: Ankle fractures account for 9% of all fractures seen in the United Kingdom. 15,000 of these fractures undergo operative fixation each year. Soft tissue swelling impacts on timing of fixation due to fears of infection and wound dehiscence. The use of arterio-venous foot pumps (AVFP) is increasing in this population although the evidence for their efficacy is unclear. In order to address this, we present an overview of the evidence for AVFP device use following ankle fracture...

Dyslexic children show impaired in postural stability. The aim of our study was to test the influence of foot soles and visual information on the postural control of dyslexic children, compared to non-dyslexic children. Postural stability was evaluated with TechnoConcept(®) platform in twenty-four dyslexic children (mean age: 9.3±0.29years) and in twenty-four non-dyslexic children, gender- and age-matched, in two postural conditions (with and without foam: a 4-mm foam was put under their feet or not) and in two visual conditions (eyes open and eyes closed)...

Waardenburg syndrome (WS) is a rare disorder comprising sensorineural deafness and pigmentation abnormalities. Four distinct subtypes are defined based on the presence or absence of additional symptoms. Mutations in six genes have been described in WS. SOX10 mutations are usually associated with a more severe phenotype of WS with peripheral demyelinating neuropathy, central dysmyelinating leukodystrophy and Hirschsprung disease. Here we report a 32 year-old man with a novel heterozygous missense variant in SOX10 gene, who presented with congenital deafness, Hirschsprung disease, iris heterochromia, foot deformity and intermediate conduction velocity length-dependent sensorimotor neuropathy...

Hypomagnesemia is associated with the development of neuropathy and abnormal platelet activity, both of which are risk factors for diabetic foot ulcer (DFU). This study was carried out to evaluate the effects of magnesium administration on wound healing and metabolic status in subjects with DFU. This randomized, double-blind, placebo-controlled trial was performed among 70 subjects with grade 3 DFU. Subjects were randomly divided into two groups (35 subjects each group) to receive either 250 mg magnesium oxide supplements or placebo daily for 12 weeks...

INTRODUCTION: The Mark III (MIII) space suit assembly (SSAs) implements a multibearing, hard-material hip brief assembly (HBA). We hypothesize that: 1) the MIII HBA restricts operator mobility and agility which manifests in effects to gait parameters; 2) the waist bearing provides rotational motion, partially alleviating the restrictions; and 3) there are resistive, speed-dependent torques associated with the spinning bearings which further diminish mobility and agility. METHODS: A subject (Suited and Unsuited) performed two planetary tasks-walking forward (WF) and backward (WB)...

BACKGROUND: Gait Initiation (GI) is a functional task representing one of the first voluntary destabilizing behaviours observed in the development of a locomotor pattern as the whole body centre of mass transitions from a large to a small base of support. Conversely, Gait Termination (GT) consists in the transition from walking to standing which, in everyday life, is a very common movement. Compared to normal walking, it requires higher control of postural stability. For a safe GT, the forward movement of the body has to be slowed down to achieve a stable upright position...

The aim of this retrospective study was to assess the hospitalizations of patients with or without diabetes mellitus (DM) who underwent nontraumatic lower extremity amputation (NLEA) with regard to demographic and hospitalization-related variables. It is a high proportion of hospital beds in developing countries, for patients with diabetes mellitus with lower extremity complications. Nontraumatic amputations of lower extremities rates is an important indicator to assess the effectiveness of efforts to reduce chronic complications related to diabetic foot...

Jyoshid R Balan
BACKGROUND: The defects over the leg, foot and ankle are best covered with a thin pliable flap. The use of muscle flap for the reconstruction of these defects leaves a grafted, aesthetically inferior result. The medial sural artery perforator (MSAP) free flap gives a thin pliable tissue for the reconstruction with better aesthesis. METHODS: The study design was retrospective case analysis over a period of 2 years. All the patients who underwent flap for leg, foot and ankle defect reconstruction in the form of MSAP free flap were included in the study...

BACKGROUND: Patients with intermittent claudication (IC) tend to walk slower and consume approximately 40% more oxygen during walking compared with healthy individuals. An unfavorable locomotion pattern has been suggested to explain this metabolic inefficiency. However, detailed knowledge of gait parameters in IC is lacking. METHODS: In a cross-sectional study, the gait pattern of newly diagnosed IC patients was compared with that of healthy controls. Spatiotemporal gait parameters such as step length and duration of stance phase were obtained by a photoelectric technique (OptoGait; Microgate, Bolzano, Italy)...

The management of displaced, intra-articular calcaneal fracture represents a surgical challenge to even an experienced orthopedic surgeon. Plate osteosynthesis using an extended lateral approach is complicated by soft tissue problems, while those treated by closed reduction and percutaneous pinning cannot address all the intra-articular fragments sufficiently. The objective of our study is to evaluate restoration of subtalar joint and long-term functional outcomes in intra-articular displaced calcaneal fractures treated with transverse subcondral screws through a small incision on lateral aspect of calcaneus and percutaneously placed axial screws through the calcaneal tuberosity...

The motor control properties of the right and left legs are dependent on the stabilization and mobilization features of the motor tasks. The current investigation examined the right and left leg control differences - interlateral asymmetries - during static single leg stance and dynamic goal directed kicking with an emphasis of the asymmetrical stabilization and mobilization components of movements. Ten young, healthy, right-leg preferred individuals with minimal kicking experience completed both tests on each limb...

OBJECTIVES: Diabetic foot ulcer (DFU) is a common and major manifestation in patients with diabetes. Oxidative stress (OS) plays an important role in diabetic complications, such as DFU. Nitric oxide deficiency contributes to the impairment of diabetic wound healing. The aim of this study was to examine the association between the eNOS Glu298Asp polymorphism and DFU and oxidative stress in patients with type 2 diabetes mellitus in an Iranian population. METHODS: In this case-control study, 123 patients with type 2 diabetes and DFU and 134 patients without DFU were recruited...

BACKGROUND: Despite the long-anticipated possibility of putting sequence alignment on the same footing as statistical phylogenetics, theorists have struggled to develop time-dependent evolutionary models for indels that are as tractable as the analogous models for substitution events. MAIN TEXT: This paper discusses progress in the area of insertion-deletion models, in view of recent work by Ezawa (BMC Bioinformatics 17:304, 2016); (BMC Bioinformatics 17:397, 2016); (BMC Bioinformatics 17:457, 2016) on the calculation of time-dependent gap length distributions in pairwise alignments, and current approaches for extending these approaches from ancestor-descendant pairs to phylogenetic trees...

Performance metrics such as speed, cost of transport, and stability are the driving factors behind gait selection in legged locomotion. To help understand the effect of gait on the performance and dynamics of small-scale ambulation, we explore four quadrupedal gaits over a wide range of stride frequencies on a 1.43g, biologically-inspired microrobot, the Harvard Ambulatory MicroRobot (HAMR). Despite its small size, HAMR can precisely control leg frequency, phasing, and trajectory, making it an exceptional platform for gait studies at scales relevant to insect locomotion...

Elizabeth R Boyer, Timothy R Derrick
Our purpose was to compare joint loads between habitual rearfoot (hRF) and habitual mid/forefoot strikers (hFF), rearfoot (RFS) and mid/forefoot strike (FFS) patterns, and shorter stride lengths (SLs). Thirty-eight hRF and hFF ran at their normal SL, 5% and 10% shorter, as well as with the opposite foot strike. Three-dimensional ankle, knee, patellofemoral (PF) and hip contact forces were calculated. Nearly all contact forces decreased with a shorter SL (1.2-14.9% relative to preferred SL). In general, hRF had higher PF (hRF-RFS: 10...
