Customized insole preparation method based on biomechanics

Abstract

The invention discloses a customized insole preparation method based on biomechanics. The method comprises the steps that a motion condition and a sole pressure distribution condition of a user are subjected to three-dimensional motion collection and dynamics measurement respectively, wherein the motion condition refers to the situation that the user stays at a standing posture, walks and moves upand down a slope, and a pressure distribution peak value area is determined; foot three-dimensional data of the user is collected, and a foot three-dimensional solid model and an insole primary modelare established; the contact area is increased, the material performance is changed, the height of an insole of an area where pressure peak values are located is adjusted according to the method, thepressure peak values are lowered in sequence, the front-back stress ratio and internal-external stress ratio of the feet are improved, and the stability of a transient-state posture is improved. According to the customized insole preparation method based on the biomechanics, the prepared customized insole effectively improves the sole pressure distribution condition of a user, increases the comfort degree, has the prevention and orthopaedic functions, and can meet demands of various types of users.

Description

technical field [0001] The invention relates to the field of preparation of customized insoles, in particular to a method for preparing customized insoles based on biomechanics. Background technique [0002] The load on the foot is 120% of the body weight when walking and up to 275% when running. According to a research report by the American Foot and Ankle Orthopedic Association, women suffer from foot pain 9 times more than men. Common foot diseases include corns, allergies, flat feet, high arches, frequent sprains, and plantar tendons. Meningitis, etc., serious plantar ulcers, diabetic feet, heel pain, etc., have affected people's daily life. Previous studies on the standing posture of adults without leg and foot disorders found that when standing barefoot, the pressure on the heel is 60% of the overall weight, 8% on the midfoot, 28% on the forefoot, and 4% on the toes. The maximum pressure it bears is 2.6 times that of the forefoot. In the forefoot, the second metatar...
