OBJECTIVE: Toe filler combined to ankle-foot orthosis (AFO) can be used to improve gait after a partial foot amputation. The AFO supports the plantar aspect of the foot, and the toe filler gives a longer lever arm that helps for pivoting over the lost metatarsals. However, the AFO type can influence gait parameters. The objective of this study case was to evaluate the effect of prosthesis with toe filler combined to: - an articulated AFO; - a fixed carbon-fiber AFO on gait. PATIENTS AND METHODS: A gait analysis was practiced on a 20-year-old male with a partial foot amputation...

BACKGROUND: Many individuals with cerebral palsy wear ankle foot orthoses during daily life. Orthoses influence joint motion, but how they impact muscle remains unclear. In particular, the gastrocnemius is commonly stiff in cerebral palsy. Understanding whether orthoses stretch or shorten this muscle during daily life may inform orthosis design and rehabilitation. OBJECTIVES: This study investigated the impact of different ankle foot orthoses on gastrocnemius operating length during walking in children with cerebral palsy...

BACKGROUND: Odontogenic tumors such as ameloblastic fibro-odontoma (AFO) are rare conditions in children and are often asymptomatic. AFOs are found by routine clinical and radiological examination or when they cause obvious intra- or extra-oral swelling. MATERIALS AND METHODS: A case of an AFO in a 7-year-old girl is described, and 107 cases from the literature and this report are analyzed. RESULTS: The total of 108 cases revealed the average age at presentation of AFO to be 6...

BACKGROUND AND PURPOSE: Foot equinus and leg length discrepancy (LLD) are common problems in hemiplegic cerebral palsy (hCP), both causing secondary deviations of pelvic motion during gait. It can therefore be assumed that the spinal deviations observed in hCP patients are secondary as a compensation for the position of the pelvis arising from the disturbed leg function. This study investigated the effects of correcting lower extremity function by orthotics on spinal gait kinematics in hCP patients...

Flavonoids are a large class of polyphenolic compounds ubiquitously distributed in dietary plants with an array of biological activities. Flavonols are a major sub-class of flavonoids featuring a hydroxyl group at C-3. Certain natural flavonols, such as quercetin and fisetin, have been shown by in vitro cell-based and in vivo animal experiments to be potential anti-prostate cancer agents. However, the Achilles' heel of flavonols as drug candidates is their moderate potency and poor pharmacokinetic profiles...

BACKGROUND: Proprioception is important for proper motor control. As the central nervous system modulates how sensory information is processed during movement (sensory gating), proprioceptive tests performed at rest do not correlate well with performance during dynamic tasks such as walking. Proprioception therefore needs to be assessed during movement execution. OBJECTIVES: 1) To develop a test evaluating the ability to detect movement errors during walking, and its test-retest reliability; 2) to quantify the relationship between proprioceptive threshold (obtained with this new test) and performance in a standardized dynamic balance task...

Ameloblastic fibro-odontoma (AFO) is a mixed odontogenic tumor that presents epithelial and mesenchymal components. Ameloblastic fibro-odontoma is generally diagnosed between the first and second decades of life and normally shows a slow clinical growth in the posterior portion of the maxilla or mandible, being mostly associated with 1 or more impacted teeth. Radiographic features of AFO show a radiolucent well-defined, uni, or multilocular defect due to containing variable amounts of calcified material. The enucleation of the tumor is the usual conduct and should be followed up for a long period of time...

BACKGROUND: Branch atheromatous disease (BAD) is differentiated from lacunar infarction (LI). BAD is often associated with neurological deterioration in the acute stage, but outcome of BAD patients in the chronic stage is unclear. We aimed to explore the outcome of BAD in the lenticulostriate artery (LSA) territory in comparison with those of LI from the viewpoint of activities of daily living (ADLs). METHODS: We retrospectively investigated patients who were admitted within 3 days after stroke onset...

INTRODUCTION: Unloader braces are non-surgical treatment options for patients with unicompartmental knee osteoarthritis (OA). However, many patients do not adhere to brace treatment because of complications related to discomfort and poor fit. An alternative to knee bracing is an ankle-foot orthosis (AFO) with a lever arm that presses the lower leg into valgus or varus. The aim of this study is to evaluate the clinical benefits of this AFO for patients with unicompartmental knee OA. MATERIALS AND METHODS: Twenty-three patients with knee OA were enrolled in this observational study...

Nitrate-nitrogen is a common contaminant of drinking water in many agricultural areas of the United States of America (USA). Ingested nitrate from contaminated drinking water has been linked to an increased risk of several cancers, specific birth defects, and other diseases. In this research, we assessed the relationship between animal feeding operations (AFOs) and groundwater nitrate in private wells in Iowa. We characterized AFOs by swine and total animal units and type (open, confined, or mixed), and we evaluated the number and spatial intensities of AFOs in proximity to private wells...
