BACKGROUND:  After thumb amputations, restoration of function and aesthetic can be accomplished with microvascular free toe flaps. However, many patients in clinical practice do not choose this reconstruction despite positive reported outcomes. This study aims to determine patients' perceptions with respect to free toe flaps to improve areas of informed consent. METHODS:  A retrospective survey was administered to patients with thumb amputations. Participants were required to complete a questionnaire about patient demographics, the Brief Michigan Hand Questionnaire (bMHQ), the standard gamble/time trade-off questionnaires for utility scores, and a questionnaire investigating potential reasons for electing not to undergo a free toe transfer...

Footwear impressions are one of the most common forms of evidence to be found at a crime scene, and can potentially offer the investigator a wealth of intelligence. Our aim is to highlight a new and improved technique for the recovery of footwear impressions, using three-dimensional structured light scanning. Results from this preliminary study demonstrate that this new approach is non-destructive, safe to use and is fast, reliable and accurate. Further, since this is a digital method, there is also the option of digital comparison between items of footwear and footwear impressions, and an increased ability to share recovered footwear impressions between forensic staff thus speeding up the investigation...

The relationship between static foot structure characteristics and knee joint biomechanics during walking, or the biomechanical response to wedged insoles are currently unknown. In this study, 3D foot scanning, dual X-ray absorptiometry and gait analysis methods were used to determine structural parameters of the foot and assess their relation to knee joint loading and biomechanical response to wedged insoles in 30 patients with knee osteoarthritis. In multiple linear regression models, foot fat content, height of the medial longitudinal arch and static hind foot angle were not associated with the magnitude of the knee adduction moment (R2  = 0...

OBJECTIVE: Patient adherence is a challenge in offloading diabetic foot ulcers (DFUs) with removable cast walkers (RCWs). The size and weight of an RCW, changes to gait, and imposed limb length discrepancies may all discourage adherence. This study sought to determine whether RCW size and provision of a contralateral limb lift affected users' comfort and gait. RESEARCH DESIGN AND METHODS: Twenty-five individuals at risk for DFUs completed several 20-m walking trials under five footwear conditions: bilateral standardized shoes, a knee-high RCW with shoe with or without an external shoe lift contralaterally, and an ankle-high RCW with shoe with or without an external shoe lift contralaterally...

Despite substantial recent interest in walking barefoot and in minimal footwear, little is known about potential differences in walking biomechanics when unshod versus minimally shod. To test the hypothesis that heel impact forces are similar during barefoot and minimally shod walking, we analysed ground reaction forces recorded in both conditions with a pedography platform among indigenous subsistence farmers, the Tarahumara of Mexico, who habitually wear minimal sandals, as well as among urban Americans wearing commercially available minimal sandals...

Excessive vertical ground reaction force (VGRF) loadrates have been linked with running injuries. Increasing cadence (CAD) has been shown to reduce loadrates; however relationships between habitual cadence and loadrates across a population of runners have not been examined. PURPOSE: To examine the relationships between habitual running cadence and vertical loadrates in healthy and injured runners using habitual footstrike patterns. As CAD increased, we expected vertical loadrates would decrease...

BACKGROUND: Patients with Charcot foot arthropathy report a poor quality of life following the development of deformity. Their quality of life is often not improved with "successful" historic accommodative treatment. There is increased current interest in operative correction of the acquired deformity with the stated goals of achieving both the traditional goals of resolution of infection and limb salvage as well as the desire to improve quality of life. The Short Musculoskeletal Functional Assessment (SMFA) outcomes instrument appears to be a valid tool for evaluating this complex patient population...

Illegal trade is a major threat to the biodiversity and the efforts initiated for the conservation of wildlife. The shortcomings of the traditional taxonomic identification methods have been coped by a revolutionary and emerging technique, the "DNA (Deoxyribonucleic Acid) barcoding". Here we report a case of trader who was allegedly making footwear for a famous international celebrity from wild animal cutis. The samples confiscated during a raid on a footwear manufacturing industry by KP Wildlife department in August, 2016, were received by Bioresource Research Centre (BRC) for molecular identification on 1st September, 2016...

Various methods are used to measure hip and knee joint motion angles; however, their use is often limited by cost or inability to measure dynamic movements. The assessment of movement patterns is clinically useful in individuals with osteoporosis (OP) and osteopenia (OPe) through its potential to optimize fracture risk assessment. This study evaluates the inter-rater reliability of using DartfishTM 2-D Motion Analysis Software to measure maximum flexion and extension angles at the hip and knee in individuals with OP or OPe while performing five tasks of the Safe Functional Motion test...

This study aimed to determine whether there is a relationship between abnormal foot position and standing and walking ability in individuals with Rett syndrome (RTT), a rare neurological condition primarily affecting females, often accompanied by impaired gross motor function and musculoskeletal deformities. Through means of an online survey, physiotherapists were asked to share information about their work and experience with individuals with RTT. They were asked about their clients' scores on the Rett Syndrome Gross Motor Scale and measures of their foot deformity, passive range of motion of dorsiflexion of the foot, use of supportive footwear, pressure load on the foot, and symmetry in weight bearing...

Flip-flops may change walking gait pattern, increase muscle activity and joint loading, and predispose wearers to foot problems, despite that quantitative evidence is scarce. The purpose of this study was to examine the lower limb muscle co-contraction and joint contact force in flip-flops gait, and compare with those of barefoot and sports shoes walking. Ten healthy males were instructed to perform over-ground walking at self-selected speed under three footwear conditions: 1) barefoot, 2) sports shoes, and 3) thong-type flip-flops...
