Method and system for brace designing

Method and system for brace designing. The method comprises the following steps: S1) fixing a subject requiring a brace; S2) acquiring skeletal image information of the subject; S3) determining an adjustment solution for implementing an adjustment with respect to the subject and a target state that is to be achieved ultimately; S4) adjusting the subject to alter the skeletal structure of the subject; S5) acquiring adjusted skeletal image information of the subject; S6) determining whether the skeleton of the subject has been adjusted to the target state; if yes, then terminating adjustment and entering step S7; if not, then returning to step S4; S7) acquiring the body surface three-dimensional shape of the subject having achieved the target state and recording information of the force applied by an adjusting head to the subject for use in manufacturing a corresponding brace; thus allowing the highly efficient designing of a brace.

In another embodiment of the present invention the prosthetic appendage is a hand. The prosthetic hand includes a wrist element with one end configured to receive the outer extremity of an amputated hand, a base portion attached to the wrist element and a plurality of modular and three-dimensionally printed finger elements selectively coupled to adjacent finger elements or the base to form prosthetic fingers.

Shape optimization for prosthetic feet

A passive prosthetic foot enables a below-knee amputee to walk with near able-body walking motions. The prosthetic foot includes a resilient heel that enables the heel to strike a walking surface more softly than in the prior art and more accurately transition the leg from swing phase to stance phase. The prosthetic foot is modeled generally as a wide Bézier curve, and the foot is characterized according to a set of at least 12 variables, including h, C1d, C2x, C2y, C2d, C3x, C3y, C3d, C4x, C4d, C5d and C6d, where C3y is heel size, C4x is heel geometry and C6d is curve intersection location. The variables are optimized to minimize a difference between a normal lower leg trajectory during gait and a modeled trajectory that includes the prosthetic foot.
