Abstract

This invention relates to a method and system for evaluating parameters in the fabrication of a scoliosis orthosis. First, the initial position of the robotic arm is calculated based on the user's own treatment parameters. Then, the force applied to the robotic arm is continuously increased in preset steps until the maximum tolerable thrust position is found. Next, the relevant parameters of the maximum thrust position are used to convert the correction parameters, and the obtained correction parameters are input into a model to obtain the current correction model. The correction model and its associated parameters are sent to the orthotist to assist in orthosis design. In this invention, the orthotist can intuitively understand the quantitative relationship between the degree of contact between the orthosis and the body, the corrective force, and the spinal correction effect. Combined with the patient's surface images and spinal X-rays, the orthosis design is performed, reducing the problems encountered by the orthotist during the design process regarding the required pressure or the appropriate distance the orthosis needs to be close to the body to determine the resulting spinal deformation.
