Testing the plantar pressure distribution plays a vital role in the design and production of corrective insoles.
By testing the pressure distribution in different areas of the sole, scientific data can be provided for the design and customization of corrective insoles.
Plantar pressure testing is generally performed through a plantar pressure distribution test system. There are three main test modes: static test, dynamic test, and balance test.
Generally, for the design and production of corrective insoles, only static testing is required.
People stand still on the plantar pressure plate, and then collect plantar pressure distribution data. The whole process generally takes only a few tens of seconds to complete, and a detailed plantar pressure test report will be obtained.
In the report, the data contains: plantar high pressure area, plantar pressure imbalance area, gait parameters, center of gravity trajectory, etc.
In addition, the report will also conduct scientific evaluations of human foot abnormalities, such as flat feet, high arches, inversion, eversion, etc.
When designing corrective insoles, the corrective design is mainly adjusted from the following aspects:
1. Adjust the support of the arch.
According to the height of the arch, choose the appropriate support material to avoid excessive collapse of the arch.
2. Adjust the force distribution on the sole of the foot.
For example, in the high-pressure area, add appropriate cushioning materials to achieve the effect of dispersing the pressure distribution.
3. Adjust the heel.
For example, by adjusting the inclination angle, the effect of improving gait can be achieved.
After the design is completed, the insole is generally made by a 3D printer or an insole engraving machine.
After the production is completed, the user will be asked to try it on. If it feels obviously uncomfortable, it needs to be adjusted again so that the corrective insole can achieve a better correction effect.
In addition, it is possible to visit the user regularly, evaluate the correction effect regularly, and then optimize and adjust to ensure that the corrective insole can achieve a continuous correction effect.
