Computer assessment of feet

Computer assessment of feet examines the plantar surface of the foot to obtain information about the spatial configuration of the foot arch.


What does the examination look like?

The computer aided device (CQ-St) to assess feet was designed and manufactured to facilitate the examination of the body posture and early detection of postural defects. The aim is to record a reliable and objective image of the plantar surface of the foot. The examination helps to adjust exercises or possibly recommend some orthopaedic equipment (that is shoe insoles).

Advantages of the examination:

  • A 3D spatial scanner to record the feet arches with the foot loaded and unloaded
  • Assessment of load thanks to colourful imaging of pressure intensiveness
  • Observation of valgus / varus heel
  • Analysis of actual centre of gravity line by a four sensor stabilographic platform
  • Computerized dynamic posturography

The examination is non-invasive and harmless.
You don't need a doctor's prescription.


Indications for the computer assessment of feet

  • Feet and leg deformities (flat feet, plano-valgus feet, high arch etc.)
  • Walking pattern disorders
  • Problems to keep balance
  • Pain in lower limbs

Preparation for the examination

A patient has to put their feet on a transparent plate where they are photographed. The image of the feet is observed by a CCD video camera and processed into a digital signal, which is later sent to a computer. Right after the examination its results are thoroughly analysed and the patient gets full records plus measurements which are quickly compared to standards.


How often do you need to do the examination?

During an examination with a podoscope you can check the results of treatment or preventive therapy, therefore the frequency depends on individual problems. It is usually recommended every 3 or 4 months. A patient receives the examination results where they can read about:

  • Longitudinal arch (Clarke angle and Godunov-Sztriter index)
  • Transversal arch (heel angle Gamma, Wejsflog index)
  • Foot length and width
  • Hallux valgity angle Alfa
  • Toe varus deformity angle Beta

Thanks to integrated numeric adjustment of geometrical distortions the imaging accuracy is at 1 mm. In reality it is impossible to show on a patient's skin physiological points with higher accuracy than 5 mm.
