The design and control of active ankle-foot orthoses
Ankle foot orthoses (AFOs) can be used to ameliorate the impact of impairments to the lower limb neuromuscular motor system that affect gait. Existing AFO technologies include passive devices with fixed and articulated joints, semi-active devices that modulate damping at the joint and active …

Enhancing the Effectiveness and Availability of Orthoses by Additive Manufacturing
… long-term residual ankle symptoms. Ankle foot orthoses (AFOs) are the primary intervention for treating and preventing recurrent sprains by providing timely external mechanical support to the ankle joint. However, traditional AFOs are often rigid, heavy, and ill-fitting due to their …

An investigation into the variable biomechanical responses to antipronation foot orthoses
… influence biomechanical responses to foot orthoses. On the basis that forces applied to the sole of the foot pass through plantar soft tissues prior to being applied to bones of a joint to affect moments and kinematics, study 2 characterised how soft tissue respond to change in external …

Investigation of bench methods for determining stiffness of solid ankle-foot orthoses
The applications of ankle-foot orthoses (AFOs) are nowadays the most common treatment for the compensation of neuromuscular disorders usually caused by stroke and spinal cord or peripheral nerve injuries. The biomechanical functions of plastic AFOs are determined by their thickness, the material …

Study of mechanical characteristics of ankle-foot orthoses using finite element analysis method
Ankle-foot orthoses (AFOs) are external devices applied to the lower leg segment in patients with ankle joint impairment due to neuromusculoskeletal disorders resulting in abnormal gait. In the last three decades, plastic AFOs have superseded conventional metal AFOs. Prescriptions of AFOs by …

The effect of foot orthoses on muscle activity and morphology, foot biomechanics and skin sensitivity
Foot orthoses with a medial wedge or medial arch support are commonly used to treat musculoskeletal pathologies by altering external forces applied to the foot, which could consequently alter internal forces generated by muscles. However, little is known about whether systematic changes in foot …

The effects of body fat percentage on inter-vertebral spinal mobility control from hyperextension spinal orthoses
Hyperextension spinal orthoses are common modalities in treating vertebralfractures. Their objective is to retain the spine in a hyperextended position tooffload the fractured vertebra(e) and allow healing. To date, accurate insight intothe efficiency of hyperextension spinal orthoses is absent. In …

The use of Tone Relieving Ankle-Foot Orthoses in the management of children with cerebral palsy
Tone Relieving Ankle Foot Orthoses (TRAFOs) have been used in the management ofneurophysically impaired patients for some years within the United States and during thelast few years they have been introduced in the UK. The main difference between aTRAFO and a standard polypropylene ankle foot …

Effects of two different types of ankle foot orthoses on gait outcomes in patients with subacute stroke
Ankle Foot Orthosis (AFO) is a commonly prescribed device to improve foot drop and gait in patients with stroke. The purpose of this study was to identify whether patients in the subacute stage of stroke, with foot drop, would have better gait outcomes when using a double adjustable AFO (DA AFO), …

Experience of Play Participation and Use of Lower Extremity Orthoses in Children with Cerebral Palsy: Case Study
… with cerebral palsy (CP) using lower extremity orthoses (LEOs) in natural play contexts. CP is the most commonly occurring motor disability in childhood. Associated with CP, impairments in functional mobility, spasticity, varying degrees of muscle tone, ROM, and impaired gross and fine motor …

Initial Development of a Patient-Reported Item Bank to Assess Mobility of People Who Use Lower Limb Orthoses
Item banks are contemporary health survey instruments used to efficiently measure patient-reported outcomes that may be difficult to observe in a clinical or research setting. Item banks designed specifically for measuring outcomes among people who receive a specific intervention often include …

Development of a Mobility-Enabling Spinal Orthosis and Methods for Evaluating and Developing Spinal Orthoses on a Robotic Platform
… and development platform capable of producing orthoses with predictable effects on spinal loads. Research objectives were thus to a) develop an advanced robotic test platform (RTP) for the rapid development of spinal orthoses, b) use the RTP to evaluate a commercial decompressing orthosis, c) …

Effectiveness of a foot orthosis on muscular activity in functional ankle instability
… (FI). It is considered valid that foot orthoses as well as sensorimotor training have a positive effect on ankle muscle activity in healthy individuals and those with lower limb overuse injuries or flat arched feet (reduced reaction time by sensorimotor exercises; increased ankle muscle …

The effectiveness of foot orthoses as a treatment for plantar ulceration in leprosy : a study of the efficacy, acceptability, appropriateness and implantation of a podiatric regimen
… and plantar ulceration, were fitted with orthoses and allocated to an experimental group. Thirty-four similar subjects, were not offered orthoses and were allocated to a control group. After 8 months 52% of the ulcers presented by Experimental group and 12% of the ulcers presented by the …

The kinematic effects of three quarter and full length foot orthoses on anterior knee pain sufferers when walking and descending stairs
… joint is often attributed to foot function. Foot orthoses are commonly prescribed for this condition; however the mechanisms by which they work are poorly understood. Previous studies using single segment foot models have hypothesised that it may be control of the midfoot which hold the key to …

The direct effects of variations in AFO stiffness on the kinematics and kinetics of gait
… in combination with physical therapy. Briefly, orthoses, and in particular ankle-foot orthoses (AFOs), are externally applied devices designed to maintain the foot in a desirable position with respect to the shank. Currently, the prescription and design of orthoses is still based on the …

Rearfoot biomechanics in Achilles tendon function
… a specific focus on rearfoot function and foot orthoses. From this review research questions are defined and experimental studies proposed. Based on the outcomes of the review, the overall aim of this thesis was to identify how (1) rearfoot movement and (2) foot orthoses, might affect Achilles …

Investigating the mechanical relationship between the feet and low-back
Introduction: Claims that foot orthoses can resolve low-back pain are common in the marketing of these devices. The claims are based on the notion that wearing the orthoses will limit excess pronation at the subtalar joint thus reducing excessive internal tibial and femoral rotations. Excess leg …
