Abstract
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
The present invention relates to the method for a kind of auxiliary evaluation vola and/or ankle joint and/or stress states of knee joints.
Background technology
Existing recently standardized method (see figure 1) (the Keijsers NL of plantar pressure analysis; Stolwijk NM; Nienhuis B, Duysens J.A new method to normalize plantar pressuremeasurements for foot size and foot progression angle.J Biomech.2009; 42 (1): 87-90.), improved the shortcomings such as foot that mosaic method (masking) is lost some important informations of plantar pressure distribution and is difficult to the different sizes of comparison, different motion state.But the dynamic change that above-mentioned standardized method fails to combine gait to support the different phase of phase is further analyzed, so that the coupling mechanism more targetedly between assessment foot, ankle, knee joint.
According to the variation of plantar pressure, normal gait or the gait support phase when jogging are divided into 5 moment, 4 stages.5 moment: heel (the first foot contact that contacts to earth; FFC), front foot contact to earth (first metatarsalcontact, FMC), front and back foots support (forefoot flat, FFF), heel is liftoff (heel off; HO) and toe liftoff (last foot contact, LFC)].4 stages: heel (the initial contactphase that contacts to earth the stage; ICP), front foot (the forefoot contact phase that contacts to earth the stage; FFCP), complete sufficient driving phase (footflat phase; FFP) and front foot push off stage (forefoot push off phase, FFPOP) (De CockA, De Clercq D; Willems T, Witvrouw E.Temporal characteristics of footroll-over during barefoot jogging:reference data for young adults.GaitPosture.2005; 21 (4): 432-9.) (Fig. 2).Contact to earth the stage at heel (ICP) and front foot contacts to earth the stage in (FFCP) stage, before front foot revolves, and the tibia inward turning; And push off the stage (FFPOP) at complete sufficient driving phase (FFP) and front foot, front foot supination, tibia outward turning (Whittle M.Gait analysis:an introduction.3rd ed.Great Britain:Butterworth he inemann; 2002.59-62p.).
Summary of the invention
The method that the purpose of this invention is to provide a kind of auxiliary evaluation vola and/or ankle joint and/or stress states of knee joints.
Method provided by the invention comprises the steps:
Obtain the dynamic plantar pressure data of experimenter's biped or when jogging in normal gait; Data are carried out standardization; Obtain normal gait or the dynamic plantar pressure distributed intelligence of two foots when jogging, calculate normal gait or the heel portion inside pressure of left side foot and the ratio A1 and the right sufficient heel portion inside pressure and the ratio A2 of outside pressure of outside pressure in the whole time period when jogging; The said whole time period was made up of contact to earth stage and front foot stage of contacting to earth of heel; Said standardization is that Application of MATLAB R2006a software is handled;
Obtain the dynamic plantar pressure data of experimenter's biped when unilateral knee is rotated walking or jogged; Data are carried out standardization; Obtain the rotation walking of single knee joint or the dynamic plantar pressure distributed intelligence of two foots when jogging, calculate unilateral knee rotation walking or the heel portion inside pressure of left side foot and the ratio B1 and the right sufficient heel portion inside pressure and the ratio B2 of outside pressure of outside pressure in the whole time period when jogging; The said whole time period was made up of contact to earth stage and front foot stage of contacting to earth of heel; Said standardization is that Application of MATLAB R2006a software is handled;
If | A1-B1|＞0.05 or | A2-B2|＞0.05, at least one is stressed inconsistent in prompting experimenter following three positions: (1) left vola and right vola are stressed inconsistent; (2) left ankle joint and right ankle joint are stressed inconsistent; (3) left knee joint and right knee joint are stressed inconsistent.
Said standardization is that Application of MATLAB R2006a (2006 editions) software (MathWorks company) is handled.Said standardization specifically can be the method that N.L.W.Keijsers etc. provides; Referring to document: N.L.W.Keijsers; N.M.Stolwijk, B.Nienhuis, et al.A new method to normalizeplantar pressure measurements for foot size and foot progression angle.JBiomech; 2009,42:87-90..
The said time period can be passed through software Footscan software 7.2mst, and RSscan International obtains.
Experimenter's said plantar pressure data can obtain through plantar pressure force plate test macro.Said plantar pressure force plate test macro can be the dull and stereotyped test macro of altofrequency of Footscan SCSI; (Belgian RSscan company produces specifically to can be the dull and stereotyped test macro of the long altofrequency of FootscanSCSI2 rice; 2 * 0.4m, 16384 pick offs, 125-500Hz).
Said unilateral knee rotation can be unilateral knee inward turning or unilateral knee outward turning.Said jogging can be: earlier with heel portion land, velocity is at 3.0 ± 0.3m/s.The speed of said normal gait can be 1.5 ± 0.3m/s.
Use above method, the dynamic change that can combine gait to support the different phase of phase is carried out further standardization and is analyzed plantar pressure, more targetedly the coupling mechanism between assessment foot, ankle, knee joint.Also can be aided with other method, further confirm.Use method of the present invention, the dynamic plantar pressure that can analyze fast and accurately under the different sufficient and different actions distributes, and the physiological relation between the sufficient knee joint, thereby instructs various training or motion, prevents that damage from taking place.
