Abstract
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.
Claims14
An orthopedic device, comprising:
- a main support adapted to secure about a lower leg, wherein the main support defines a curved shape having a semi-rigid or rigid form, and arranged to resiliently maintain the curved shape between donning and doffing of the orthopedic device;
- at least one strap extending from the main support and arranged to wrap about an ankle;
- a strap assembly having a first portion coupling to the main support, and a second portion arranged to be drawn therefrom, the strap assembly including a main segment and at least one elastic segment attached to the main segment, the strap assembly located between the first and second portions, the main segment being less elastic than the at least one elastic segment and including the first portion;
- an anchor for receiving and attaching to the second portion of the strap assembly;
- an attachment component secured to the main support the first portion of the strap assembly coupling to the attachment component, the attachment component including a base and lateral wings extending laterally from the base over the main support and forming the curved shape of the main support, the base being centrally located on the main support at an apex of the curved shape thereof.
An orthopedic device, comprising:
- a main support adapted to secure about a lower leg, wherein the main support defines a curved shape having a semi-rigid or rigid form, and arranged to resiliently maintain the curved shape between donning and doffing of the orthopedic device;
- at least one strap extending from the main support and arranged to wrap around an ankle;
- a strap assembly having a first portion coupling to the main support, and a second portion arranged to be drawn therefrom, the strap assembly including a main segment and at least one elastic segment attached to the main segment, the strap assembly located between the first and second portions, the main segment being less elastic than the at least one elastic segment and including the first portion;
- a foot component adapted to secure about a foot;
- an anchor for receiving and attaching to the second portion of the strap assembly and selectively positioned on a foot component, wherein the anchor is adjustable from a relative to a neutral strap assembly orientation to an offset orientation, such that the strap assembly extends at a non-parallel angle between the main support and the anchor relative to the neutral orientation;
- an attachment component secured to the main support the first portion of the strap assembly coupling to the attachment component, the attachment component including a base and lateral wings extending laterally from the base over the main support and forming the curved shape of the main support, the base being centrally located on the main support at an apex of the curved shape thereof.
