Custom foot orthotics

Foot-drop is one of the most diagnosed and physically limiting symptoms persons with multiple sclerosis (pwMS) experience. Clinicians prescribe ankle-foot orthosis (AFO) and functional electrical stimulation (FES) devices to help alleviate the effects of foot drop, but it is unclear how their clinical and functional gait improvements compare given the user's level of disability, type of multiple sclerosis, walking environment, or desired physical activity. The research questions explored were what is the current state of AFO and FES research for pwMS? What are the prevailing research trends? What definitive clinical and functional device comparisons exist for pwMS? eight databases were systematically searched for relevant literature published between 2009 and 2021...

Recent scientific evidence supports the idea that foot plantar stimulation increases the functional connectivity of brain regions involved in visuo-spatial and sensory-motor integration. In this before-after, non-randomised intervention study we assessed the change in several gait and postural parameters using inertial sensor measurements after acute plantar stimulation using custom 3D-printed insoles. The pilot study was performed on 22 institutionalised, older individuals with a high comorbidity burden who either walked autonomously or with the help of a cane...

Diabetic individuals with peripheral neuropathy are at risk for the development of foot ulcers due to musculoskeletal abnormalities and abnormal loading in the gait cycle leading to elevated plantar pressures. To prevent diabetic foot ulcers, practitioners should regularly screen patients for the presence of neuropathy as well as neuroarthropathies and prescribe the appropriate shoes and orthotics based on the best available clinical evidence. Although not widely available, there is potential for data-driven customization of orthotics and shoe wear based on plantar pressure data to prevent the development of diabetic foot ulcers more effectively, and ultimately prevent lower limb amputations...

People with lower limb impairment can participate in activities such as running with the use of a passive-dynamic ankle-foot orthosis (PD-AFO). Specifically, the Intrepid Dynamic Exoskeletal Orthosis (IDEO) is a PD-AFO design that includes a carbon-fiber strut, which attaches posteriorly to a custom-fabricated tibial cuff and foot plate and acts in parallel with the impaired biological ankle joint to control sagittal and mediolateral motion, while allowing elastic energy storage and return during the stance phase of running...

Dynamic joint stiffness (or simply "stiffness") is a customization criteria used to tune mechanical properties of orthotic and prosthetic devices. This study examines metatarsophalangeal (MTP) joint stiffness during the toe-rocker phase of barefoot walking and establishes baseline characteristics of MTP joint stiffness. Ten healthy individuals walked at 4 speeds (0.4, 0.6, 0.8, and 1.0 statures·s-1) over level ground. MTP sagittal plane joint angles and moments were calculated during the toe-rocker phase of stance...

BACKGROUND: Metatarsalgia is a common affliction in rheumatoid arthritis (RA), often requiring aggressive pharmacologic treatment that carries associated adverse effects. The aim of this study was to investigate whether simple insoles would have a beneficial effect on forefoot pain, disability, and functional limitation in participants with RA experiencing forefoot pain. METHOD: A prospective, quasi-experimental, pretest-posttest trial was performed at a rheumatology outpatient clinic...

BACKGROUND: Foot orthoses are commonly used as a noninvasive treatment to relieve foot pain. The custom full-length insoles with various materials and designs have been studied for their effectiveness in reducing plantar pressure. However, few studies have been conducted with respect to custom medial arch support on the relationships between material hardness and measured plantar pressure and level of comfort. OBJECTIVES: To evaluate the effects of the hardness of custom medial arch supports on plantar pressure and comfort perception...

BACKGROUND: Plantar fasciitis is one of the most common causes of heel pain. The plantar fascia supports the longitudinal arch and absorbs ground reaction forces during the static and dynamic phase(s) of weight-bearing. The purpose of this randomized controlled trial study was to determine the effects of CAD/CAM foot orthoses that were designed based on the dynamic plantar pressure in patients with plantar fasciitis. METHODS: This study was performed on 34 patients with plantar fasciitis...

OBJECTIVE: To determine the effect of foot orthoses on pain, disability and foot functionality in patients with Systemic Lupus Erythematosus. DESIGN: Randomized clinical trial. SETTING: University Podiatric Clinical Area. SUBJECTS: Patients with systemic lupus erythematosus. INTERVENTIONS: Patients were randomly assigned to either group A, which received custom-made functional foot orthoses, or group B, which received flat cushioning insoles, for three months...

Posterior tarsal tunnel syndrome (PTTS) is an entrapment neuropathy due to compression of the tibial nerve or one of its terminal branches within the tarsal tunnel in the medial ankle. The tarsal tunnel is formed by the flexor retinaculum, while the floor is composed of the distal tibia, talus, and calcaneal bones. The tarsal tunnel contains a number of significant structures, including the tendons of 3 muscles as well as the posterior tibial artery, vein, and nerve. Focal compressive neuropathy of PTTS can originate from anything that physically restricts the volume of the tarsal tunnel...

BACKGROUND: In clinical practice, specific customization is needed to address foot pathology, which must be disease and patient-specific. To date, the traditional methods for manufacturing custom functional Foot Orthoses (FO) are based on plaster casting and manual manufacturing, hence orthotic therapy depends entirely on the skills and expertise of individual practitioners. This makes the procedures difficult to standardize and replicate, as well as expensive, time-consuming and material-wasting, as well as difficult to standardize and replicate...

Ankle-foot orthoses (AFO) are prescribed to improve the patient's quality of life. Supporting weak muscles or restraining spastic muscles leads to smoother and more stable locomotion. Commonly, AFO are made using thermoplastic vacuum forming, which requires a long time for production and has limited design options. Additive manufacturing (AM) can solve this problem, leading to a faster and cheaper solution. This review aimed to investigate what is the state-of-art using AM for AFO. Evaluating the used manufacturing processes, customization steps, mechanical properties, and biomechanical features in humans would provide significant insights for further research...

BACKGROUND: Solid ankle-foot orthoses (SAFOs) are frequently prescribed in conditions such as cerebral palsy and stroke. Although gait is improved in the short term, long-term effects of limiting ankle and foot motion during functional activities on joints such as the knee have not been investigated. Our study purpose was to compare tibiofemoral (TF) motion in shoe and SAFO conditions in healthy adults to inform future studies in clinical populations. METHODS: A custom-made device using electromagnetic sensors was used to collect three-dimensional TF rotation data while 29 healthy adult participants (female participants = 19, age = 24...

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: Orthopedic footwear is often prescribed to improve postural stability during standing and walking in individuals with Hereditary Motor Sensory Neuropathy. However, supporting evidence in literature is scarce. The aim of this study was to investigate the effect of orthopedic footwear on quiet standing balance, gait speed, spatiotemporal parameters, kinematics, kinetics and dynamic balance in individuals with Hereditary Motor Sensory Neuropathy. METHODS: Fifteen individuals with Hereditary Motor Sensory Neuropathy performed a quiet standing task and 2-min walk test on customized orthopedic footwear and standardized footwear...

Customized foot orthosis is commonly used to modify foot posture and relieve foot pain for adult acquired flexible flatfoot. However, systematic investigation of the influence of foot orthotic design parameter combination on the internal foot mechanics remains scarce. This study aimed to investigate the biomechanical effects of different combinations of foot orthoses design features through a muscle-driven flatfoot finite element model. A flatfoot-orthosis finite element model was constructed by considering the three-dimensional geometry of plantar fascia...

BACKGROUND: Foot orthoses have consistently demonstrated an improvement in pain scores for plantar fasciitis. The fabrication of custom-made foot orthoses (CFOs) can vary between clinicians and may include the use of different materials and casting techniques. This cross-sectional study's objective was to quantify plantar pressure for two CFOs, one with a heel plug (HP) and one without. METHODS: Fourteen healthy participants (8 men and 6 women; 35.4 ± 7.7 years) were cast by the same practitioner...
