Design of A Variable-Stiffness Ankle-Foot Orthosis Emulator
Ankle-foot orthoses (AFOs) are passive devices used to improve gait in children with cerebral palsy. They are characterized by a torsional stiffness and ankle neutral angle. For this project, a lightweight ankle exoskeleton was designed to emulate the spring-like behavior of a traditional AFO for a …

The effect of wedge height on the gait of normal subjects wearing a swift cast
… rehabilitation goals for stroke patients. Ankle foot orthoses (AFOs) are regularly prescribed to help achieve this goal for stroke patients who have suffered from strokes or other neurological disorders with lower limb disabilities. When customising AFOs evidence suggests that tuning the …

Individual plantar flexor compensation during walking with a unilateral passive dynamic ankle-foot orthosis : a simulation study
Ankle foot orthoses (AFOs) are designed to improve walking ability in persons with a variety of musculoskeletal and neuromuscular disorders. Passive dynamic AFOs (PD-AFOs) are a special class of orthoses that function like a torsional spring, which store elastic energy in early stance and release …

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 In the last three decades, plastic AFOs have superseded conventional metal AFOs.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 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 …

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 …

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 …

Design of actuation system and minimization of sensor configuration for gait event detection for Gen 3.0 Portable Powered Ankle-Foot Orthosis (PPAFO)
Powered ankle-foot orthoses (AFOs), which are capable of providing assistive torque at the ankle joint, have significant potential as both assistance and rehabilitation devices. Technology advancements have led to great progression in the development of powered AFOs. Our group had developed the …

On improving control and efficiency of a portable pneumatically powered ankle-foot orthosis
Ankle foot orthoses (AFOs) are widely used as assistive and/or rehabilitation devices to correct gait of people with lower leg neuromuscular dysfunction and muscle weakness. An AFO is an external device worn on the lower leg and foot that provides mechanical assistance at the ankle joint. Active …

Enhancing the Effectiveness and Availability of Orthoses by Additive Manufacturing
… people suffer from musculoskeletal conditions. Ankle inversion sprains are the most prevalent acute injuries, causing temporary mobility restrictions and long-term residual ankle symptoms. Ankle foot orthoses (AFOs) are the primary intervention for treating and preventing recurrent sprains by …

Sensory re-weighting for balance control and the effects of ankle foot orthoses and stance width: A comparison of people with diabetic peripheral neuropathy and healthy participants
… as adopting a wider stance width and wearing Ankle Foot Orthoses (AFOs) may also affect sensory input as well as altering the mechanics of the ankle and hip joints. The impact of distal sensory loss on the sensory control of balance in people with DPN compared to the healthy population is …
