(3) Results and analysis of the experiments
a. The volunteers had the guidance of experimenters to change from a healthy sitting position to a stooped relaxed sitting position. The motion process is illustrated in figures 7-9 for the motion limb under the motion capture system.
It can be seen from fig. 7-9 that when the sitting posture of the body changes, the angles of different vertebra parts of the human body in the vertical direction change in different sizes, and the distance between the adjacent small marks changes (namely, the skin size in the vertebra direction changes).
FIG. 10 shows a software analysis of the 4 th and 5 th intersphere distance 45 variation in the spinal direction for volunteer c, which was divided into 4 segments (red box-marked areas) by experimental movements of the comparative volunteers. Part 1 is a data error zone, and the main reason for this phenomenon is that the volunteer c does not keep a static posture after the experiment begins; part 2 is an experimental waiting area, and the distance between the marked small balls in a healthy sitting posture can be calculated through the part; part 3 is an experimental dynamic area, and the part is that volunteer c carries out sitting posture transformation after hearing instructions; the part 4 is an experiment completion area, and the distance between the marked small balls after the volunteer completes the action of bending and sitting.
After preliminary deletion and analysis of experimental data in the first experiment, it is found that the relative angle change of the human spine in the transverse direction (namely, the direction of the XZ plane) is not obvious in the sitting posture change process of a volunteer, and the position deviation is within 4.3 degrees; the relative angles of the spine of the volunteer to the vertical direction (namely to the YZ plane) and the XY plane are obviously changed, and the sum of the change angle of the spine to the YZ plane and the change angle to the XY plane is 90 degrees. Since the YZ plane is a positive direction of the spine of a human body in the experiment, the YZ plane is taken as a reference plane for exploring the angular change of the spine in the vertical direction in the experiment, as shown in fig. 11.
And analyzing and sorting the experimental data of the six volunteers (a-f) to obtain a comparison table of relative angle changes of adjacent small balls and YZ surfaces after the sitting posture changes and before the sitting posture changes, as shown in tables 2-7.

Further, fig. 12 and 13 show a line graph of the relative angle change rate of the six volunteers along the YZ plane and a line graph of the absolute value of the relative angle change rate during the sitting posture change, respectively.
As can be seen from tables 2 to 7 and fig. 12 and 13, in the process from the healthy sitting posture to the stoop sitting posture of the utility model, the angle change rate of the spine basically follows the process of first becoming larger, then becoming smaller and then becoming larger from top to bottom (the position of the spine). The variation degree of the spinal angle variation rate of the six volunteers is larger on the whole, and the variation degree of the spinal angle variation rate is not fixed. The angular change rates of the vertebrae of the six volunteers at the positions of the marked small ball combination 34 (the positions of the vertebrae) are all similar, and the angular change rates of the vertebrae of the six volunteers at the positions have the minimum standard deviation of 151.04%, 143.15%, 147.03%, 149.11, 139.57 and 138.95, so that the angular change rates of the six volunteers can be in the range of 138% -152% by taking the positions of the marked small ball combination 34 as reference positions (namely the areas between the shoulder point connecting line and the next length unit of the human body) for researching the change of the vertebrae of the human body. The experimental result of the volunteer b slightly deviates from the results of the other two volunteers, and the comparison of the vertebral line graphs of the six volunteers shows that the curvature of the chest and waist of the volunteer is larger than that of the other five volunteers, but no obvious bone diseases exist, and the experimental result is not greatly influenced.
The second experiment researches the size change relationship of the back size of the human body in the sitting posture change process. Volunteers were instructed by experimenters to change from a healthy sitting position to a stooped relaxed sitting position.
In this, fig. 14 shows the analysis of the distance variation software of the marked bead combination 2122 stuck on the back of the volunteer c, which is divided into five parts (areas marked by red borders) by the experimental movements of the comparative volunteers. Part 1 is a data error zone, and the main reason for this phenomenon is that volunteer c does not keep a static posture after the experiment begins; part 2 is an experimental waiting area, and the distance between the marked small balls in a healthy sitting posture can be calculated through the part; part 3 is an experimental dynamic area, and the part is that volunteer c carries out sitting posture transformation after hearing instructions; part 4 is the stable area of posture, and the volunteer is to the stability of health posture after finishing bending over the position of sitting. The part 5 is an experiment completion area, and the distance between the marked small balls after the volunteer completes the stooping and sitting posture can be calculated through the part.
The experimental data of six volunteers are analyzed and collated to obtain comparison tables of the distances between the adjacent small balls after the sitting posture changes and before the sitting posture changes, which are respectively shown in tables 8-13.
TABLE 8
TABLE 9
TABLE 11
TABLE 12
Further, fig. 15 shows a line graph of the comparison of the size change rate between different lines of the back size during the sitting posture change for six volunteers.
As can be seen from tables 8 to 13 and FIG. 15, the back sizes of the human bodies were all increased in the process from the healthy sitting posture to the stooped sitting posture, but the change rates were different. The method can preliminarily obtain that the size change rate of the skin of the second row is the largest when the small label balls are adhered in the experimental area when the volunteer changes from a healthy sitting posture to a stooped sitting posture, namely the size change of the skin in the skin area of the second row is the largest in the sitting posture change process, and the skin size change rate is about 7% -12%.
