Gravity center shift in balance test process is the basis of posturography parameter evaluation, and all will use in the calculating of seven described below parameters, general gravity center of human body (center ofgratitude, COG) is before the second rumpbone.Center of gravity projection in this system refers to gravity center of human body's projection on the footrests, and due to human body, to be in side force in standing balance process very little, and therefore gravity center of human body's projected position test philosophy just can be reduced to:
x＝(F
A+F
B-F
C-F
D)·L/G
y=(F
B+F
D-F
A-F
C)·M/G
In formula, L is the distance of O (O point is pedal detection platform center, left and right) to the X-axis of sensor, M is the distance of O point to the Y-axis of sensor, G be after loss of weight by the weight of instruction person's human body, F A, F B, F C, F D is respectively the reading of four sensors, and sensor symmetry to be placed on below the pedal of left and right as shown in Figure 2, and stressed size is recorded by sensor.
In air bag loss of weight stands still process, assessed frontal plane hunting frequency by instruction person to change, reflect within a certain period of time, center of gravity is projected in the change frequency of frontal plane and horizontal direction positive and negative values, only represent the speed that center of gravity projected position changes along X-direction in the algorithm, this parameter value is larger, namely the frequency changed is higher, and reflect by instruction person's shake more serious, gravity's center control is more unstable.
Frontal plane hunting frequency change algorithm is: by the gravity center shift in above-mentioned static balancing test process, then moves to right side area from left field according to the projection of patient's center of gravity and move to the number of times of left field and the ratio of time from right side area, that is:
In formula, N is the number of times that center of gravity projection swings from left field to right side area and from right side area to left field, and T is the testing time selected.
Average center of gravity when assessment air bag loss of weight stands still, reflects and stands still in motion process, and two lower limb are exerted oneself balance, and absolute value is less, and represent that balanced degree is better, on the occasion of larger, comparatively left lower extremity is stronger to show right lower extremity; Negative value is larger, then on the contrary.Clinical data shows, average center of gravity projection value is larger, and body symmetry is poorer, as stroke hemiplegin person.It is defined as patient's center of gravity project migration apart from the ratio of sum with times of collection, and computational methods are:
In formula, Gi is the position at every turn gathering the project migration of center of gravity on pedal plate; I=1,2,3,4 ... N (i, N are integer), N are counting of the testing time interior collection selected.
Frontal plane maximum amplitude of oscillation when assessment air bag loss of weight stands still, reflects by the maximum of the two lower limb of instruction person firmly degrees of offset in the X direction.The maximum amplitude of oscillation of frontal plane shows more greatly by instruction person under loss of weight state, stand still motion time about two lower limb to exert oneself difference, this difference is relevant with body symmetry, and difference shows that more greatly symmetry is poor, and stability is weak.Relevant disease as amputee, hemiptegic.
It is defined as the ultimate range of patient's center of gravity project migration normal center of gravity projection zero-bit, and its computational methods are:
Smax=Max|Si|
In formula, Si is the length of each center of gravity project migration gathered normal center of gravity projection zero-bit, i=1,2,3,4 ... N (i, N are integer).
When assessment air bag loss of weight is stood, the average amplitude of oscillation of frontal plane, reflects that shake severe degree and speed in the X direction in standing process, it is poorer that its value shows more greatly by instruction person's balanced capacity, relevant disease by under instruction person's loss of weight state.Its computational methods are:
In formula, Si is the length of each center of gravity project migration gathered normal center of gravity projection zero-bit, i=1,2,3,4 ... N (i, N are integer), N are counting of the testing time interior collection selected.
When assessment air bag loss of weight stands still, center of gravity projection motion track total length, reflects by under instruction person's loss of weight state, and center of gravity projection motion track total length when standing still, its value shows that more greatly center of gravity project migration distance summation is longer, poorer by instruction person's balanced capacity.
According to track classification (centre type, Qian Houxing, left right model, multicenter type, diffusion-type), assessing and judge by instruction person's state, is normally multicenter type.The computational methods of multicenter type center of gravity projection motion track total length are:
In formula, Xi, Y i is the coordinate at every turn gathering center of gravity project migration position.I=0,1,2,3,4 ... N (i, N are integer).
When assessment air bag loss of weight stands still, the center of gravity projection motion track gross area in the unit interval, reflects stability and balanced degree that health in the unit interval controls center of gravity.Setting same period under, to the different rehabilitation training phase carry out front and back contrast, determine training effect, numerical value is larger, reflect stability and balance poorer, as Parkinson's, cerebellar ataxia etc.In unit interval, center of gravity projection motion track gross area algorithm is:
In formula, Xi, Y i is the coordinate of the position at every turn gathering the project migration of center of gravity on pedal plate.I=0,1,2,3,4 ... N (i, N are integer); Tc is each time gathered.
Frontal plane side slew rate in unit interval when assessment air bag loss of weight stands still, reflection in the X-axis direction the maximum amplitude of oscillation time center of gravity projection translational speed, its value is larger, and expression gravity's center control is poorer.Relevant disease is as torsion-spasm, chorea etc.Its computational methods are:
In formula, S ' max is the previous sampled value of the maximum amplitude of oscillation of frontal plane, and T is the sampling time.
In air bag loss of weight static balance training, the computational methods of good center of gravity percentage are assessed: when being exerted oneself symmetrically and evenly by instruction person left and right bipod by instruction person, if its center is normal center of gravity zero-bit, represent center of gravity all drop on right crus of diaphragm to depart from normal center of gravity zero-bit+50%, represent center of gravity all drop on left foot to depart from normal center of gravity zero-bit-50%, center of gravity drop on from the normal each region of center of gravity zero-bit (± 5%, ± 5% to ± 10%, ± 10% to ± 20%, ± 20% to ± 30%) the computing formula of time ratio as follows:
In formula, n3 be center of gravity from the above-mentioned each value of normal center of gravity zero-bit (± 5%, ± 5% to ± 10%, ± 10% to ± 20%, ± 20% to ± 30%) number of times that swings in scope in region, N is counting of gathering in testing time of selecting;
The value that center of gravity drops on from normal center of gravity zero-bit ± 5% is larger, and it is better to show by instruction person's state, and ± 10% takes second place, ± 20% more to take second place, ± take second place for 30% time.Such as, after certain person patient twice rehabilitation training, the time controlled within ± 5% is 20% than all, and the percentage of time of gravity's center control within ± 10% increases, then can prove the validity of rehabilitation training equally.
