This invention relates to a method for predicting key points of the internal skeleton based on plantar surface data, belonging to the field of computer vision. The method includes: acquiring an X-ray image of a patient's foot and labeling key points of the foot bones in the image; acquiring a depth map of the same patient's foot based on the camera viewpoint at the time of acquiring the X-ray image, and registering the edge contours of the X-ray image and the depth map to associate the labeled key points in the X-ray image with the features of the depth map; inputting the registered depth map into an improved YOLOv8-pose model to train the model, thereby enabling the model to predict key points of the foot bones based on the foot depth map. This invention can extract key points of the plantar bones in a faster, lower-cost, and non-invasive manner. These key points can be used to diagnose skeletal developmental disorders such as flat feet and high arches, and have significant clinical diagnostic value.

Provided is an assistive device for stabilizing posture in a tiptoe stance, said device being capable of improving athletic ability, reducing or eliminating foot pain, and improving effects by stabilizing posture in track and field sports involving performance or competition requiring a tiptoe stance with the toes bent toward the instep side of the foot. A sock-shaped body 2 is provided with a lower cloth 2a as a sheet-shaped bottom part that overlaps the distal ends of first to third metatarsal bones on the plantar surface of the foot to be assisted. A pad 1 for compensating the difference in distance between the ground contact surface and the distal ends of at least two metatarsal bones from among the first to third metatarsal bones is provided on the upper surface side of the lower cloth 2a in at least one position where the distal ends of the first to third metatarsal bones are close to each other when a tiptoe stance posture in which the toes are bent toward the instep side of the foot is assumed when the body 2 is worn. The pad 1 comprises a contour having an acute angular portion with a rounded tip, and a flat surface part having a constant thickness or at least two flat surface parts having different thicknesses.

To provide an orthodontic insert. An orthotic insert for use in footwear may include a support shell. The support shell may include a forward portion configured to underlie and support the plantar surface of the metatarsal head area of ​​a user's foot and a rearward portion configured to underlie and support the plantar surface of the heel of the user's foot. The rearward portion may include a heel post for providing frontal plane stabilization to the user's foot during use. The heel post may define a peripheral structure having a hexagonal or other geometric shape extending downwardly from a bottom surface of the support shell and terminating in a substantially planar footwear-engaging surface.

A rear-entry ankle brace includes an elastomeric component defining an inside elbow channel configured to span an ankle joint. A channel opening extends the length of the elastomeric component for direct insertion on top of a leg. One or more leg straps are used to adjustably tension first and second rear edges of the channel opening toward one another and secure the brace to the lower leg. Two foot straps are used to adjustably tension first and second bottom edges of the channel opening toward one another and secure the brace to the mid-foot. The foot straps overlap on the bottom to define a plantar surface of the brace and cross over each other on the topside of the elastomeric component and are secured to a leg strap. A pair of stabilizing stirrups optionally are included on the inside surfaces of the elastomeric component and receive the malleoli.
