BACKGROUND: In children with unilateral spastic cerebral palsy (USCP), ankle-foot orthoses (AFOs) are widely used to correct common gait deviations such as a drop-foot pattern. Most studies on this topic have investigated specific time points while omitting other parts of the gait cycle. OBJECTIVES: This study investigated the separate effects of prefabricated carbon fiber AFOs and custom-made hinged AFOs compared with barefoot walking in children with USCP with a drop-foot gait pattern using statistical parametric mapping...

Ameloblastic fibro-odontoma (AFO) is a rare, gnathic, benign, mixed odontogenic tumor that commonly presents in the first or second decade of life as a unilocular and rarely multilocular radiolucency with variable amounts of calcified material. Tumor progression is typically indolent, and generally accepted treatment is surgical enucleation and curettage. This case report describes an atypical presentation in a 14-year-old male with a multilocular, aggressive AFO requiring hemimandibulectomy with immediate osseous and dental "Jaw-in-a-Day" reconstruction...

BACKGROUND: Ankle-foot orthoses (AFOs) are vital in gait rehabilitation for patients with stroke. However, many conventional AFO designs may not offer the required precision for optimized patient outcomes. With the advent of 3D scanning and printing technology, there is potential for more individualized AFO solutions, aiming to enhance the rehabilitative process. OBJECTIVE: This nonrandomized trial seeks to introduce and validate a novel system for AFO design tailored to patients with stroke...

Cerebral palsy poses challenges in walking, necessitating ankle foot orthoses (AFOs) for stability. Gait analysis, particularly on slopes, is crucial for effective AFO assessment. The study aimed to compare the performance of commercially available AFOs with a new sports-specific AFO in children with hemiplegic cerebral palsy and to assess the effects of varying slopes on gait. Eighteen participants, aged 6-11, with hemiplegia, underwent gait analysis using GRAIL technology. Two AFO types were tested on slopes (uphill +10 deg, downhill -5 deg, level-ground)...

Lower extremity peripheral artery disease (PAD) is a cardiovascular condition manifesting from narrowed or blocked arteries supplying the legs. Gait is impaired in patients with PAD. Recent evidence suggests that walking with carbon fiber ankle foot orthoses (AFOs) can improve patient mobility and delay claudication time. This study aimed to employ advanced biomechanical gait analysis to evaluate the impact of AFO intervention on gait performance among patients with PAD. Patients with claudication had hip, knee, and ankle joint kinetics and kinematics assessed using a cross-over intervention design...

Exoskeletons and orthotic devices are commonly used in physical rehabilitation. However, these devices, fitting intimately with the human body, often lead to skin-related issues amongst users. Misalignments between orthotic and anatomical joints cause relative sliding motion between the limb and orthosis and also cause pressure points on the limb, which may contribute to these skin problems. This research quantifies the effects of sagittal plane ankle-joint misalignments for an ankle-foot orthosis (AFO) user during walking...

OBJECTIVE: To compare the kinematic effects of two widely-used prefabricated ankle-foot orthoses (AFOs), the Dyna Ankle (DA) and UD Flex (UD), on the gait cycle of patients with hemiplegia due to cerebral palsy or acquired brain injury. METHODS: This was a retrospective cohort study involving 29 patients. Gait analysis results were assessed under three conditions: barefoot, with the DA, and with the UD. Friedman tests and post hoc analysis with Bonferroni correction were performed to assess differences between the three conditions...

OBJECTIVE: To investigate the immediate effects of plastic ankle foot orthosis (AFO) on locomotor performance in patients with stroke and determine how such effects might undergo alteration when distinct plantarflexor (PF) module subtypes are considered. DESIGN: Cross-sectional study. SETTING: Two university hospitals. PARTICIPANTS: Fifty-two stroke patients and twenty-one healthy controls. INTERVENTIONS: Not applicable...

Patients with stroke often use ankle-foot orthoses (AFOs) for gait improvement. 3D printing technology has become a popular tool in recent years for the production of AFOs due to its strengths on customization and rapid manufacturing. However, the porosity of the 3D printed materials affects the kinetic features of these orthoses, leading to its lower-strength than solid ones. The effective elastic modulus of 3D printed material was measured following standard test method to obtain the kinetic features precisely in a finite element simulation...

Lower limb orthoses are frequently used in children suffering from cerebral palsy (CP) alongside rehabilitation. The aim of this study was to analyze the effectiveness of ankle-foot orthosis (AFO) and knee-ankle-foot orthosis (KAFO) in walking, balance maintenance, spasticity, and quality of life improvement during rehabilitation in children affected by CP. The hypothesis was that the use of orthoses could improve the parameters compared to non-use. A systematic review was conducted in the main databases, including English language RCTs published about the use of AFO and KAFO in combination or not with rehabilitation methods in children affected by CP and studies mentioning walking, balance, muscle length, and quality of life as outcomes...

OBJECTIVES: Bone fragility fracture (BFF) is a serious incident in treating rheumatoid arthritis (RA). We hypothesized that pain degree during treatment RA correlated with incident BFF and validated how pain affects incident BFF (inc-BFF). METHODS: Postmenopausal RA patients treated for at least 3 years were recruited. The primary endpoint was the development of inc-BFF. Follow-up began with the first bone mineral density measurement (baseline) and continued until the development of the first BFF or termination of the study...

OBJECTIVES: This study aims to investigate the effects of romosozumab on bone mineral density (BMD) and bone metabolism. METHODS: In this retrospective case series, romosozumab was administered to 5 premenopausal female patients with osteoporosis and anorexia nervosa with fragility fractures. BMD and bone turnover marker changes were investigated at 6 months and 1 year after administering romosozumab. RESULTS: BMD increased and high-turnover bone metabolism decreased 6 months and 1 year after administering romosozumab...

OBJECTIVES: High altitude possesses a great challenge for human survival owing to low oxygen tension and has been reported to cause bone deterioration among sojourns of high altitude. The bone health of Ladakhi women is investigated for the first time in this study. METHODS: Dual energy X-ray absorptiometry of Ladakhi women and sea level women was done at the radius and calcaneus using EXA-3000 (Osteosys, Korea), followed by colorimetric and Enzyme Linked Immunosorbent Assay analysis of parameters regulating bone health...

Hypophosphatasia (HPP), also called Rathbun disease, is a rare genetic disorder that is caused by the loss-of-function mutation in the ALPL gene encoding tissue non-specific alkaline phosphatase. Doctor Rathbun first described the case of a 3-week-old infant who presented with severe osteopenia, rickets, and multiple radiographic fractures, and died shortly after of epileptic seizure and respiratory distress. The term "hypophosphatasia" was coined as the patients' alkaline phosphatase levels were significantly low...

OBJECTIVES: This cross-sectional study, conducted as part of the Bushehr Elderly Health program stage II in Bushehr, Iran, aimed to evaluate health-related quality of life (HR-QoL) in individuals aged ≥ 60 with osteosarcopenia, a condition characterized by the co-occurrence of osteopenia/osteoporosis and sarcopenia. Given the increasing elderly population worldwide, understanding the HR-QoL of this demographic is crucial, with osteosarcopenia being a significant factor. METHODS: The study enrolled 2369 participants aged ≥ 60 and collected demographic and anthropometric data...

OBJECTIVES: Chronic kidney disease (CKD) complicated by secondary hyperparathyroidism (SHPT) is associated with an increased risk of fragility fractures. Etelcalcetide (EC) is a treatment for SHPT that reduces serum parathyroid hormone (PTH) levels. However, the effects of combined treatment with osteoporosis drugs such as teriparatide (TPTD) remain unclear. This study investigates the combined effects of EC and TPTD on bone in CKD model rats. METHODS: The CKD model was established in 8-week-old male Wistar rats by feeding them a 0...

As China's "double carbon" goal continues to advance, logistics as a key area of carbon emissions and low-carbon logistics center site selection are key links in the process. However, existing studies on logistics center location often ignore the impact of demand uncertainty, which leads to a waste of resources in the planning and construction processes. We take logistics cost and carbon emission as the objectives, and the multi-objective site selection model established based on stochastic programming theory takes demand uncertainty as a stochastic constraint...

At least 128,000 patients in the United States each year suffer from foot drop. This is a debilitating condition, marked by the inability to dorsiflex and/or evert the affected ankle. Such patients are rendered to a lifetime of relying on an ankle-foot orthosis (AFO) for walking and nighttime to prevent an equinovarus contracture. Contrary to popular belief, foot drop can be caused by more than just insult to the common peroneal nerve at the fibular head (fibular tunnel). It is a common endpoint for a diverse spectrum of nerve injuries, which may explain its relatively high prevalence...

BACKGROUND: Ankle-foot orthoses (AFOs) are orthopaedic devices often prescribed to treat foot drop. For patients who are not satisfied with off-the-shelf solutions, custom AFOs personalized to the patient's lower limb anatomy are required. Dynamic AFOs provide stability while allowing for physiological ankle mobility in the stance phase of walking. RESEARCH QUESTION: Can a morphology-based dynamic custom AFO made of fiberglass-reinforced polyamide restore a quasi-normal gait pattern and improve comfort in patients with foot drop? METHODS: In this pilot study, the legs and feet of ten foot drop patients (age=64...
