Feet, foot, orthotics

The aim was to find if foot orthotics alone can improve flat feet in children and analyze how the addition of Zukunft-Huber manual therapy and corrective bandaging changes the outcome. Forty-nine children aged 5 to 10 with asymptomatic flexible flat feet were divided into 2 groups. The first was treated with foot orthoses alone, in the second wearing foot orthoses was supplemented with Zukunft-Huber manual therapy and corrective bandaging. Pedobarography during gait was performed before the therapy and after a year...

To systematically review the efficacy of split tendon transfer surgery on gait-related outcomes for children and adolescents with cerebral palsy (CP) and spastic equinovarus foot deformity. Five databases (CENTRAL, CINAHL, PubMed, Embase, Web of Science) were systematically screened for studies investigating split tibialis anterior or split tibialis posterior tendon transfer for spastic equinovarus foot deformity, with gait-related outcomes (published pre-September 2022). Study quality and evidence were assessed using the Methodological Index for Non-Randomized Studies, the Risk of Bias In Non-Randomized Studies of Interventions, and the Grading of Recommendations Assessment, Development and Evaluation...

OBJECTIVES: Stroke patients suffer from ankle joint deformities due to spastic ankle muscles. This study evaluated the viability of using 3D scanned surface images of the feet of stroke victims to visually assess the deformities of a hemiparetic foot and investigated the influences of deformed ankle joints on gait kinematics. METHODS: A total of 30 subjects with stroke-induced hemiparesis and 11 age-matched healthy controls completed the clinical assessments. We analyzed their feet's morphometric characteristics using a 3D scanner, identified convenient anthropometric measurements, and conducted gait trials on even and uneven terrains...

STUDY DESIGN: Randomized crossover with additional case study...

BACKGROUND: Adult acquired flat foot (AAFF) is a symptomatic postural alteration of the foot due to modifications in bony structures and/or soft tissues supporting the medial longitudinal arch. For the most severe cases, when orthotic solutions do not provide enough pain relief, surgery may be necessary. RESEARCH QUESTION: Is it possible to restore a normal medial longitudinal arch and to correct the static and dynamic frontal plane alignment of the rearfoot via a modified Grice surgical procedure in AAFF patients? METHODS: Eleven patients with stage II AAFF were recruited in the study and underwent the Grice procedure...

BACKGROUND: Severe flexible flatfeet with triceps surae complex shortening are prognostically unfavorable in early childhood and may compromise normal foot development. METHODS: This retrospective, IRB-approved study included 20 children (38 feet) under 6 years with severe flexible flatfeet and triceps surae complex shortening. Treatment included minimally invasive percutaneous achilles tendon lengthening followed by a 4-week cast fixation and corrective orthotic therapy under talo-navicular reposition for at least 6-months...

INTRODUCTION: Progressive collapsing foot deformity (PCFD) is frequently associated with a gastrocnemius contracture. Surgical treatment of PCFD often includes a gastrocnemius recession in addition to other corrective procedures, which typically requires a period of restricted weight bearing postoperatively. Isolated gastrocnemius recession may allow passive correction of the deformity, improve orthotic fit, and obviate the need for full reconstruction and restricted weight bearing. The goal of this study was to evaluate patient-reported outcomes after an isolated gastrocnemius recession for flexible PCFD in patients anticipated to have difficulty with postoperative restricted weight bearing...

BACKGROUND: Individuals living with diabetes run an increased risk of developing diabetic foot ulcers (DFUs), leading to high costs to society and reduced quality of life for the individual. Regular screening is important to avoid complications. AIM: To evaluate patients' and clinicians' experiences of using a digital tool, the D-Foot, in the screening of risk factors for developing DFUs. The secondary aims were to investigate whether patients had had their feet examined by a nurse or doctor during the past year, had been referred to podiatry and whether patients had received information about self-care...

Loeys-Dietz syndrome (LDS) is characterized by a wide spectrum of musculoskeletal manifestations, including foot deformities. The spectrum of foot deformities in LDS has not been previously characterized. Our objective was to describe the incidence and characteristics of foot deformities in LDS. We retrospectively reviewed the demographic, clinical and imaging data for patients diagnosed with LDS who were seen at our Orthopedic surgery department from 2008 to 2021. We performed descriptive analyses and compared distributions of deformities by LDS genetic mutations...

This second of a 2-part series of articles recounts the key points presented in a collaborative symposium sponsored jointly by the Arthritis Foundation and the American Orthopaedic Foot & Ankle Society with the intent to survey current treatment options for osteoarthritis (OA) of the foot and ankle. A meeting was held virtually on December 10, 2021. A group of experts were invited to present brief synopses of the current state of knowledge and research in this area. Topics were chosen by meeting organizers, who then identified and invited the expert speakers...

Introduction: The design and selection of lower-limb prosthetic devices is currently hampered by a shortage of evidence to drive the choice of prosthetic foot parameters. We propose a new approach wherein prostheses could be designed, specified, and provided based on individualized measurements of the benefits provided by candidate feet. In this manuscript, we present a pilot test of this evidence-based and personalized process. Methods: We previously developed a "prosthetic foot emulator," a wearable robotic system that provides users with the physical sensation of trying on different prosthetic feet before definitive fitting...

Pediatric flexible flat foot (PFFF) is known to in-crease the foot structure's load, causing potential disability. Foot orthoses are one of the most common non-surgical methods to improve the medial longitudinal arch of the foot for improving PFFF. However, orthoses are not routinely prescribed due to their high cost, and discomfort caused by a restriction of foot movement. Furthermore, there are no quantitative standards or guidelines for an orthotic prescription, which makes the decision-making process of less experienced podiatrists chal-lenging...

INTRODUCTION: The method of 3D printing is increasingly gaining utilization in clinical applications and may support prosthetic fitting. The aim was to compare biomechanical outcomes of people with a transtibial amputation using a novel, individualizable, 3D-printed prosthetic foot (ComfyStep, Mecuris) with two conventional, widely used prosthetic feet during level ground walking using a 3D motion analysis system. METHODS: Ten individuals with an unilateral transtibial amputation were fitted with 3 prosthetic feet (ComfyStep, Assure/Össur, DynamicMotion/Ottobock) using their current, well-fitting socket...

BACKGROUND: Foot pain is frequent among people with rheumatoid arthritis (RA). Foot orthoses (FO) are commonly prescribed with the intention to reduce pain symptoms and improve function. RESEARCH QUESTION: How do a custom-made FO affect pain, gait biomechanics and daily activity among people with RA? METHODS: Twenty-five participants with RA and foot pain completed this quasi-experimental study using a control insole for four weeks and then a custom-made FO in the following four weeks...

BACKGROUND: Despite the effects of prosthetic foot mechanical properties on gait of people with lower limb amputation, scant forefoot and heel stiffness data exist to help guide prosthetic foot prescription. OBJECTIVE: To measure forefoot and heel linear stiffness properties across commonly prescribed commercial prosthetic foot models and to describe variations in stiffness across feet targeted for users with different body weights and foot sizes. STUDY DESIGN: Mechanical testing of five types of commercial prosthetic feet across nine user body weight and foot size combinations...

BACKGROUND: Mechanical testing is the principal method used to quantify properties of commercial prosthetic feet in a controlled and standardized manner. To test feet in a mechanical testing machine without overconstraining the system, tangential shear forces must be minimized. However, there is scant published information comparing techniques for reducing shear forces during mechanical testing. Furthermore, there are no data on variability in linear stiffness across testing sessions...

BACKGROUND: Children with symptomatic flat feet (pes planus) frequently present for care but there remains uncertainty about how best to manage their condition. There is considerable variation in practice between and within professions. We intend to conduct a three-arm trial to evaluate three frequently used interventions for pes planus (exercise and advice, exercise and advice plus prefabricated orthoses, and exercise and advice plus custom made orthoses). Each of these interventions are complex and required developing prior to starting the trial...

BACKGROUND: Textured insoles have been suggested to enhance foot sensation, which contributes to controlling upright balance. However, the interaction between plantar callosity and the textured surface has not been studied. RESEARCH QUESTION: Firstly, to compare the efficacy of textured insoles on balance performance and foot position sense between two groups of older people: one group had plantar callosity, and the other did not. Secondly, to investigate the efficacy of textured insoles within each study group...

BACKGROUND: Most previous studies focused on the possible relationship between hallux valgus deformity and biomechanical characteristics in the foot and lower leg. Very few investigated the association of pelvic kinematics and hallux valgus during gait according to various foot-toe orthoses for hallux valgus. OBJECTIVE: To investigate the effect of soft or hard foot-toe orthoses on pelvic kinematics in individuals with hallux valgus deformity during gait. STUDY DESIGN: This study has a repeated measures design...
