[0016] The following examples facilitate a better understanding of the present invention, but do not limit the present invention. The experimental methods in the following examples are conventional methods unless otherwise specified. The test materials used in the following examples, unless otherwise specified, were purchased from conventional biochemical reagent stores.
[0017] The following steps are used to evaluate the difference in bilateral dynamic plantar pressure distribution of a sports enthusiast:
[0018] (1) Obtain the dynamic plantar pressure data of both feet when the subject is walking or jogging normally, and apply the method provided by N.L.W.Keijsers, etc. (N.L.W.Keijsers, N.M.Stolwijk, B.Nienhuis, et al. A new method to normalize plantar pressure measurements for foot size and foot progression angle. J Biomech, 2009, 42: 87-90.) the above data were standardized; combined with software (Footscan software 7.2mst, RSscan International), calculated the heel co...

The invention discloses a method for auxiliary evaluation of stress state of foot soles and / or ankle joints and / or knee joints. The method comprises the following steps: obtaining dynamic foot sole pressure data of normal walking of a subject, carrying out standardization for obtaining dynamic information and calculating for obtaining the ratio A1 and the ratio A2 which are the ratio of the pressure on the inner side to the pressure on the outer side of the heel of the left foot and the right foot respectively; obtaining the dynamic foot sole pressure data of bilateral knee rotation walking of the subject, carrying out the standardization for obtaining the dynamic information and calculating for obtaining the ratio B1 and the ratio B2 which are the ratio of the pressure on the inner side to the pressure on the outer side of the heel of the left foot and the right foot, wherein the standardization is processed by using MATLAB R2006a software; if the absolute value of A1-B1 is more than0.05 or the absolute value of A2-B2 is more than 0.05, the situation indicates that the stress on the left and the right foot soles, or the ankle joints or the knee joints of the subject is inconsistent. The method can fast and accurately understand the dynamic foot sole pressure distribution of different feet and under different actions, as well as the physiological relationship among feet, ankles and knees, thereby guiding a variety of training or exercise and preventing injuries.
Description
technical field [0001] The invention relates to a method for assisting in evaluating the stress state of the sole of the foot and / or the ankle joint and / or the knee joint. Background technique [0002] Plantar pressure analysis has recently been standardized (see figure 1 )(Keijsers NL, Stolwijk NM, Nienhuis B, Duysens J.A new method to normalize plantar pressure measurements for foot size and foot progression angle.J Biomech.2009; 42(1):87-90.), improved the mosaic method (masking) Some important information about plantar pressure distribution is lost and it is difficult to compare feet of different sizes and different motion states. However, the above-mentioned standardized methods fail to further analyze the dynamic changes in different stages of the gait stance phase, so as to evaluate the coupling mechanism among the foot, ankle, and knee joints in a more targeted manner. [0003] According to the change of plantar pressure, the gait support period during normal walki...
