What is the working principle of a gait analyzer? What is its general price?

There are different types of gait analyzers, with different models for different sub-fields and applications.

Among them, the plantar pressure distribution system is relatively common.

The plantar pressure distribution system mainly relies on thousands of pressure sensors built into the surface of the pressure plate. These pressure sensors can sense in real time the pressure distribution of various parts of the foot and relevant gait data when a person is standing still, walking, running, or in other states, such as the center of gravity movement trajectory, heel angle detected by cameras, walking posture, and other data.

The main data measured by 3DOE's plantar pressure distribution system include: total foot pressure, total foot contact area, forefoot pressure ratio, hindfoot pressure ratio, average pressure, step deviation angle, heel width, heel angle, maximum heel pressure, average heel pressure, center of gravity trajectory length, basic support area, body sway curve, plantar pressure line trajectory diagram, characteristic position diagram, time-dependent force change data table of characteristic positions of left and right feet, step deviation angle analysis, and other data.


The main models of 3DOE's plantar pressure distribution system include: eMat460, eMat500, eWay1500, eWay2000 and other types.

The main differences between these models are the number of sensing points and the length of the sensing plate.

Of course, customers can also customize different lengths and numbers of sensing points according to their needs, and customize different functions according to different application scenarios.

The plantar pressure distribution system has three main measurement modes, namely static measurement, balance measurement, and dynamic measurement.

Each mode of measurement is generally completed within 20 to 40 seconds, and the measurement speed is relatively fast.

Static measurement is the same as balance measurement; the subject only needs to stand still and naturally on the pressure plate. When standing, maintain a relaxed and natural state, just like standing normally in daily life.

For the dynamic mode, the subject needs to walk back and forth across the pressure plate, generally 2 to 3 times, so that the measured data will be relatively objective and accurate.

The price of the plantar pressure plate is generally between more than 20,000 and seventy to eighty thousand yuan. Different models have different prices. It is necessary to communicate with specific sales personnel about the specific application scenarios and data requirements, and then the sales staff will recommend suitable models and provide quotations.
