BACKGROUND: Understanding the concept of kinematic coupling is essential when selecting the appropriate therapeutic strategy and grasping mechanisms for the occurrence of injuries. A previous study reported that kinematic coupling between the rearfoot and shank during running and walking were different. However, because foot mobility involves not only the rearfoot but also the midfoot or forefoot, kinematic coupling is likely to occur among the rearfoot, midfoot, and forefoot segments...

Background: Foot morphology has received increasing attention from both biomechanics researches and footwear manufacturers. Usually, the morphology of the foot is quantified by 2D footprints. However, footprint quantification ignores the foot's vertical dimension and hence, does not allow accurate quantification of complex 3D foot shape. Methods: The shape variation of healthy 3D feet in a population of 31 adult women and 31 adult men who live in Belgium was studied using geometric morphometric methods...

The most common reason for a revision total ankle replacement procedure is a painful, stiff ankle even after the initial surgery. Limited and conflicting data are available regarding the change in sagittal foot and ankle range of motion after revision total ankle replacement surgery. We sought to determine whether revision total ankle replacements would reduce compensatory midfoot range of motion. In determining this, a novel radiographic measurement system with stable osseous landmarks is used. A retrospective medical record review of patients who had undergone revision total ankle replacement from January 2009 to June 2016 was performed...

INTRODUCTION: Since pregnant women may have potentially greater difficulty maintaining balance, their stability has been investigated by some researchers. However, there is no consensus considering the results. The purpose of our investigation was to compare all the experimental studies focusing on the analysis of gait that have been conducted over the last years to assess their methodological issues and changes induced by pregnancy. METHODS: The PRISMA Guidelines incorporating a risk of bias and strength of recommendations were used as a methodological template for this review...

Ankle power dominates forward propulsion of gait, but midfoot power generation is also important for successful push off. However, it is unclear if midfoot power generation increases or stays the same in response to propulsive activities that induce larger external loads and require greater ankle power. The purpose of this study was to examine ankle and midfoot power in healthy adults during progressively more demanding functional tasks. Multi-segment foot motion (tibia, calcaneus, forefoot) and ground reaction forces were recorded as participants (N=12) walked, ascended a standard step, and ascended a high step...

Background: Age-related changes in midfoot mobility have the potential to influence success with foot orthoses intervention in people with patellofemoral pain (PFP). The aim of this study was to determine whether older people with PFP demonstrate less foot mobility than younger adults with PFP. Methods: One hundred ninety four participants (113 (58%) women, age 32 ± 7 years, BMI 25 ± 4.9 kg/m2 ) with PFP (≥ 6 weeks duration) were included, with foot mobility quantified using reliable and valid methods...

A 43-year-old woman arrived to emergency unit of our hospital, referring intense deteriorated pain and swelling of midfoot. Rapid clinical evolvement of osteoarticular tuberculosis represents a potential clinical scenario. Clinicians should always include foot tuberculosis in differential diagnosis, in cases of severe clinical and radiological manifestations.

AIMS: Fractures of the navicular can occur in isolation but, owing to the intimate anatomical and biomechanical relationships, are often associated with other injuries to the neighbouring bones and joints in the foot. As a result, they can lead to long-term morbidity and poor function. Our aim in this study was to identify patterns of injury in a new classification system of traumatic fractures of the navicular, with consideration being given to the commonly associated injuries to the midfoot...

BACKGROUND: Multiple sclerosis (MS) is a complex disorder affecting subjects by multiple system impairments. Gait problems are common in subjects with MS and various factors such as; ataxia, hypertonic muscles or/and seconder musculoskeletal system deformities affect the normal plantigrade contact by disturbing accommodation of foot to the ground while walking. The aim of this study was investigating the dynamic plantar pressure distribution and time of maximum pressure in subjects with MS and determining the differences from healthy subjects (HS)...

BACKGROUND: This study aimed at identifying early risk factors for rigid relapse in idiopathic clubfoot using foot radiographs. METHODS: Thirty-four patients with 43 idiopathic clubfeet treated with the Ponseti method were retrospectively reviewed. RESULTS: There were seven rigid relapse recalcitrant to manipulation and requiring extensive soft-tissue release. Three radiograabphic measurements on the maximum dorsiflexion lateral (MD-Lat) radiograph, talocalcaneal (TaloCalc-Lat), tibiocalcaneal (TibCalc-Lat), and calcaneus-first metatarsal (CalcMT1-Lat) angles, showed significant differences between patients with and without rigid relapse...

The midfoot and forefoot are the regions of the foot distal to the talus and calcaneus and are critical to weight bearing and movement. They help support the arch of the foot, provide shock absorption, and convert vertically oriented forces into horizontal forward and propulsive movement. A spectrum of acute, subacute, and chronic conditions in these regions can cause pain and decreased function. A thorough history and physical examination should include foot and leg biomechanics, alignment, and posture in addition to palpation of painful areas...
