An orthosis for the correction of a varus/valgus malalignment of a person comprises a support device which in the frontal plane has an L shape and a support limb reaching under the foot of the person and establishing contact with a tread and a splint arrangement extending laterally upwards along the leg, said splint arrangement being connectible to the lower leg of the person via a fastening device. The splint arrangement is subdivided into a contact limb to rest laterally against the foot and a splint to rest laterally against the lower leg and to exert a torque onto the lower leg by a rotary joint which is arranged approximately at the level of the ankle joint. The orthosis allows an effective correction of the malalignment using only one foot part and a splint which extends laterally along the lower leg.

A foot lift orthosis comprising at least one tensile element which is configured, when the foot lift orthosis has been attached, to extend from a forefoot region of a foot along an arch of the foot and to exert a first tensile force onto the forefoot region in the direction of a first bearing position above an upper ankle joint, and at least one second tensile element which is configured, when the foot lift orthosis has been attached, to exert a second tensile force onto the forefoot region in the direction of a second bearing position in a heel region of the foot.

An orthopedic device is arranged as a lightweight ankle-foot orthosis providing dynamic support for drop foot or related disorders requiring dorsiflexion. The orthopedic device includes a main support adapted to secure about a lower leg, a strap assembly having a first portion coupling to the main support, and a second portion arranged to be drawn therefrom, and an anchor for receiving and attaching to the second portion of the strap assembly. The location of the anchor along a foot component enables increased medial-lateral control, and the arrangement of the strap assembly permits dorsiflexion during swing phase of a user's gait.

The invention relates to the field of human necessities and can be used in medicine, in particular, for treating patients with loss or impairment of locomotor function of the lower extremities. An ankle link of orthosis or exoskeleton contains the base element and the first lever pivotally mounted on the base element. The first strut is hinged at the upper end to the first lever, and the second strut is hinged at the upper end to the base element. The foot support is connected by the first lateral side to the lower end of the first strut and the second lateral side to the lower end of the second strut by means of hinges having at least two degrees of freedom.

The ankle foot orthosis has a foot section securable externally to a footwear worn by a user, a leg section having a leg engagement portion extending in front of the user's lower leg and being securable against a shin area of the user's lower leg, and two arm portions extending downwardly from the leg engagement portion, on opposite sides of the user's lower leg, and a hinge section having two hinge members disposed on opposite sides of the user's ankle, each hinge member having two ends being elastically stretchable away from one another, with a first one of the ends being secured to a corresponding one of the leg arm portions, and a second one of the two ends being secured to the foot section, with a spacing between the hinge members and the arm portions forming a foot engagement path allowing the user to respectively engage or disengage his foot from the footwear across the spacing.

An Active Ankle Foot Orthosis (AAFO) is provided where the impedance of an orthotic joint is modulated throughout the walking cycle to treat ankle foot gait pathology, such as drop foot gait. During controlled plantar flexion, a biomimetic torsional spring control is applied where orthotic joint stiffness is actively adjusted to minimize forefoot collisions with the ground. Throughout late stance, joint impedance is minimized so as not to impede powered plantar flexion movements, and during the swing phase, a torsional spring-damper (PD) control lifts the foot to provide toe clearance. To assess the clinical effects of variable-impedance control, kinetic and kinematic gait data were collected on two drop foot participants wearing the AAFO. It has been found that actively adjusting joint impedance reduces the occurrence of slap foot, allows greater powered plantar flexion, and provides for less kinematic difference during swing when compared to normals.

An orthosis includes a footplate having a heel portion, a midfoot portion, and a longitudinal axis extending between the heel and midfoot portions. A first deflection zone is defined along a length of the footplate anterior of the heel portion and through which the footplate is arranged to flex during gait to accommodate dorsiflexion of a foot of a user positioned on the footplate. At least one strut is connected to the heel portion of the footplate and extends upwardly therefrom and a connecting portion connects the at least one strut to the heel portion.

Ankle foot orthoses and methods of manufacturing an ankle foot orthosis. In one embodiment, an ankle foot orthosis is disclosed that includes a foot plate constructed to have both a trimmable portion and a non-trimmable portion. The ankle foot orthosis includes a spiral strut coupled with either the hindfoot region of the foot plate laterally of a mid-line for the foot plate or the midfoot region of the foot plate laterally of the mid-line. The spiral strut includes a transition portion that spirals by approximately sixty-five degrees (65) over less than one-hundred sixty millimeters (160 mm) in height from the bottom surface of the foot plate. The spiral strut also includes an adjustable portion that enables a cuff coupled thereto to be height adjustable. Methods of manufacturing the aforementioned ankle foot orthoses are also disclosed.
