AI Technical Summary
Technical Problem
Conventional ankle-foot orthoses (AFOs) lack adaptability to different terrains and activity levels, leading to inconsistent energy return, discomfort at higher speeds, and potential joint damage due to stiff struts.
Method used
An orthopedic brace with a leg cuff, footplate, and adjustable strut that allows controlled ankle motion in the sagittal plane while enabling natural movement in the frontal and transverse planes, and adjusts strut stiffness based on environmental changes.
Benefits of technology
Provides dynamic support and adaptability to various activity levels and terrain conditions, enhancing user comfort and reducing the risk of joint damage by allowing controlled ankle and foot movement.

Abstract
The present disclosure provides an orthopedic brace including: a leg cuff; a footplate; and a strut coupling the leg cuff to the footplate. The strut includes a first member with opposite first and second ends, a second member coupled at a first end to the first end of the first member, and a third member coupled at a first end to the second end of the first member. The brace further includes a first adjustable coupling element connecting the second member to the first member, and a second adjustable coupling element connecting the third member to the first member. The stiffness and / or bending location of the strut is adjustable based on the position of at least one of the adjustable coupling elements along the length of the first member.
