OBJECTIVE: The aim of this study was to analyze the relation between the flat-footedness and obesity. MATERIALS AND METHODS: A total of 1158 school children (653 male and 505 female) participated in this cross sectional descriptive study. According to their age, children were divided into three groups for each gender (6-10, 11-13, 14-18 years old). Diagnosis and severity of flatfoot was assessed in using the Dennis method. BMI of children were calculated as body weight divided by height squared (kg*m(-2))...

PURPOSE: Deformation of the talus in idiopathic congenital clubfeet is a known problem after treatment. However evidence on types of talus deformation and clinical relevance is rare. The aims of this study were first to define different types of talus deformation, and second, to evaluate the impact of these types on long-term results. METHODS: At a minimum follow-up of ten years 40 idiopathic clubfeet treated by a modified dorsomedial release were analyzed. Based on morphological appearance and the widened range of radius to length ratios (R/L-ratio) in treated clubfeet deformed tali were divided into two groups: tali with decreased R/L-ratios were classified as small-dome talus deformation (SD), tali with increased R/L-ratios were classified as flat-top talus deformation (FT)...

The pronators and supinators play a key role in the medio-lateral stability of the ankle joint complex (i.e. talo-crural and subtalar joints). We hypothesized that each shank muscle has a specific activation pattern determined by its anatomical course around the axes of the subtalar and talo-crural joints. A secondary objective was to examine the effect of foot posture on these activation patterns. Forty-nine young adults (25 normal-arched feet, 24 flat-arched feet) performed maximum voluntary isometric contractions against manual resistance in four movement directions: plantarflexion (PF), dorsiflexion (DF), pronation (PRO) and supination (SUP)...

OBJECTIVE: Premature aging syndromes are very rare and most often hereditary. Initially purely descriptive entities, these syndromes are now much better understood genetically and pathophysiologically and can now be classified according to the mechanisms involved. They often manifest as a pigmented skin dry, atrophic and sclerotic. There is no treatment for these conditions apart from that of their complications (frequent ulceration). OBSERVATIONS: Forty-five years of patient follow-up in dermatology for premature aging syndrome, addressed in our service for podiatric care...

The number of validation studies of commercially available foot pods that provide estimates of running speed is limited and these studies have been conducted under laboratory conditions. Moreover, internal data handling and algorithms used to derive speed from these pods are proprietary and thereby unclear. The present study investigates the use of foot contact time (CT) for running speed estimations, which potentially can be used in addition to the global positioning system (GPS) in situations where GPS performance is limited...

In the present study we investigated the effects of different durations of using high-heeled shoes on plantar pressure and gait. A questionnaire survey and dynamic plantar pressure measurements were performed in 20 control females and 117 females who had worn high-heeled shoes for a long time. According to the duration of using high-heeled shoes (as specified in the questionnaire), subjects were divided into a control group and five groups with different durations of use (i.e. <2years, 2-5years, 6-10years, 11-20years and >20years)...

Sagittal plane alignment of the foot presents challenges when the subject wears shoes during gait analysis. Typically, visual alignment is performed by positioning two markers, the heel and toe markers, aligned with the foot within the shoe. Alternatively, software alignment is possible when the sole of the shoe lies parallel to the ground, and the change in the shoe's sole thickness is measured and entered as a parameter. The aim of this technical note was to evaluate the accuracy of visual and software foot alignment during shod gait analysis...

PURPOSE: The goal of this study was to identify rotational abnormalities of the lower limb in adult patients with primary symptomatic flatfoot. MATERIALS AND METHODS: From September 2009 to May 2012, 24 patients (12 women, 12 men; mean age: 40 years) were prospectively included in the study. Each patient underwent radiographs of the flat foot and weight-bearing upright EOS(®) examination. Three-dimensional reconstructions of the lower extremities were performed with derived measurements (length, hip and knee parameters, rotations)...

Although much is known about the terrestrial locomotion of great apes, their arboreal locomotion has been studied less extensively. This study investigates arboreal locomotion in bonobos (Pan paniscus), focusing on the gait characteristics and spatio-temporal variables associated with locomotion on a pole. These features are compared across different substrate inclinations (0°, 30°, 45°, 60°, and 90°), and horizontal quadrupedal walking is compared between an arboreal and a terrestrial substrate. Our results show greater variation in footfall patterns with increasing incline, resulting in more lateral gait sequences...

Hallux deformities other than hallux valgus, especially those in the sagittal plane, have not yet been elucidated in the feet of patients with rheumatoid arthritis. The objectives of the present study were to classify rheumatoid arthritis hallux deformity in both the horizontal and the sagittal planes and investigate its relationship with flatfoot. Using a cross-sectional study design, we assessed patients with rheumatoid arthritis (527 feet in 274 patients) using radiographs and classified the deformity patterns of the great toes using cluster analysis...

BACKGROUND: Controversy exists regarding the structural and functional causes of hallux limitus, including metatarsus primus elevatus, a long first metatarsal, first-ray hypermobility, the shape of the first metatarsal head, and the presence of hallux interphalangeus. Some articles have reported on the radiographic evaluation of these measurements in feet affected by hallux limitus, but no study has directly compared the affected and unaffected feet in patients with unilateral hallux limitus...

BACKGROUND: Flexible flatfoot, as the most prevalent foot deformity in pediatric population still has no standardized strategy for its management hence some orthopedic surgeons have the tendency to use orthotic devices. The objective of this study is to evaluate whether orthotic shoes effect the natural course of the developing medial longitudinal arch in children diagnosed with moderate flexible flatfoot. METHODS: Fourty-five children (33 boys and 12 girls) with moderate flexible flatfoot were enrolled in this study...

A 52-year-old air conditioner mechanic presented with progressively itchy grayish white eruptions affecting the skin and mucous membranes, including his palms and soles for the past 2 months. The inner aspects of the palms and weight-bearing areas of the soles were the initial sites of presentation, resulting in a diffuse thickness of the palms and soles, which inhibited his everyday activity. The eruptions were asymptomatic but conspicuous. There was marked presence of multiple erythematous to grayish white (violaceous) flat-topped polygonal papules of varying sizes, with a few coalescing to form plaques...

Piezogenic pedal papules (PPP) are herniations of subcutaneous adipose tissue into the dermis. PPP are skin-colored to yellowish papules and nodules on lateral surfaces of feet that typically become apparent when the patient stands flat on his/her feet. Some connective tissue diseases and syndromes have been reported in association with PPP. Mitral valve prolapse (MVP) is a myxomatous degeneration of the mitral valve, characterized by the displacement of an abnormally thickened mitral valve leaflet into the left atrium during systole...

AIMS: There is increasing evidence that flexible flatfoot (FF) can lead to symptoms and impairment in health-related quality of life. As such we undertook an observational study investigating the aetiology of this condition, to help inform management. The hypothesis was that as well as increased body mass index (BMI) and increased flexibility of the lower limb, an absent anterior subtalar articulation would be associated with a flatter foot posture. PATIENTS AND METHODS: A total of 84 children aged between eight and 15 years old were prospectively recruited...
