Method and system for brace designing

A method for brace designing comprising following steps:

• S1, placing an adjustment device comprising one or more adjustment head provided with a force sensor on a subject wearing a brace, wherein the subject stands still when wearing the brace;
• S2, scanning the subject to obtain 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 according to the skeletal image information, wherein when a two-dimensional skeletal image or a three-dimensional skeletal image of the subject are obtained, an operator obtains quantitative parameters of a skeletal structure of the subject according to the two-dimensional skeletal image or three-dimensional skeletal image, wherein the quantitative parameters comprises a lateral curvature angle and a rotation angle of bones;
• current skeletal structure of the subject is parameterized by analysis and measurement, and parameters corresponding to the target state are analyzed and calculated;
• S4, adjusting the subject to change skeletal structure of the subject by using the adjustment head according to the adjustment solution, and meanwhile detecting a magnitude, direction and distribution of a force applied to the subject by the adjustment head via the force sensor, wherein the plurality of adjustment heads is operated according to the adjustment solution for adjusting the subject accordingly to change the skeleton structure of the subject and approaching the skeletal structure of the subject to the target state, wherein during the adjustment process, the adjustment head is a surface that is adjacent to corresponding portion of a body surface and in contact with the subject, wherein when the adjustment head is in contact with the subject, the force sensor starts to obtain the magnitude, direction and distribution of the force generated by the adjustment head on the subject;
• SA, determining whether the magnitude of the force applied to the subject by the adjustment head and detected by the force sensor is larger than a targeted value or whether a distribution of such force is abnormal;
• if yes, terminating the adjustment and proceeding to step S7, or else, proceeding to step S5;
• S5, scanning the subject to obtain adjusted skeletal image information of the subject after an adjustment of the subject goes through a certain time interval;
• S6, determining whether the skeletal structure of the subject has been adjusted to the target state according to the adjusted skeletal image information;
• if yes, terminating adjustment and proceeding to step S7, or else, returning to step S4, wherein in step S6, the operator obtains quantitative parameters of the skeletal structure of the subject which have been adjusted according to the adjusted two-dimensional skeletal image or three-dimensional skeletal image of the subject, and compares such quantitative parameters with the parameters corresponding to the target state, if the two of which match with each other, it indicates that the adjustment has already been made completely, then the adjustment is terminated and the process proceeds to step S7;
• if the two of which do not match with each other, it indicates that the adjustment has not already been made completely, then the adjustment is continued and the process returns to step S4;
• S7, obtaining a body surface three-dimensional shape of the subject having achieved the target state, and recording information about the magnitude, direction and distribution of the force applied to the subject by the adjustment head and detected by the force sensor for manufacturing a corresponding brace.
