How are 3D plantar scanners applied in the diagnosis of flat feet and high-arched feet?

Foot deformities such as flat feet and high-arched feet often lead to the occurrence of foot pain and other conditions after we stand for a long time or walk for a long time.

Severe cases may affect normal life.

In the past, our living standards and quality were not that high, which led to our insufficient attention to foot health. Early and timely detection and prevention were not possible, and we often did not get tested until the foot pain was unbearable or had begun to affect normal life.

Moreover, the technical means in the past had not reached the current level. Assessments were often made through the footprint method, visual inspection method and empirical judgment, which easily led to misjudgment.

And if people reach adulthood and their foot bones have formed, if they want to carry out correction again, they will need to pay a relatively high price.

Now, with the high-tech device of 3D plantar scanner, things are different. Measuring flat feet, high-arched feet, as well as pes varus, pes valgus and so on has become very simple.

For example, the self-developed 3DOE 3D plantar scanner conducts comprehensive measurement of plantar data through the optical principle of laser scanning and detects from 4 to 8 perspectives. The scanning process is simple to operate and has a fast scanning speed. The whole process only takes about 20 seconds, and the accuracy can also reach within 0.5mm. Moreover, it is an automated operation and will not cause human errors.


At present, hospitals and campuses have begun to introduce such equipment for foot health screening. With comprehensive objective data as a reference, doctors and rehabilitation therapists can more accurately judge our foot health conditions.

Especially for children and adolescents, being able to have regular foot examinations is very necessary.

Because children at this stage have not yet had their foot bones finalized, after being tested by a 3D plantar scanner, if conditions such as high-arched feet and flat feet are found, timely intervention and correction can be carried out, which can be easily cured and better maintain the foot health of adolescents.

The evaluation of flat feet and high-arched feet by plantar scanners is mainly based on arch height, footprint area coefficient and so on to conduct analysis and judgment.

This kind of analysis is based on objective and real data rather than subjective judgment, and the data is multi-dimensional. Therefore, the evaluated foot health index is relatively accurate.

In addition, 3D data such as STL measured by 3D plantar scanners can also be applied to orthotic insoles, corrective aids and other aspects.
