Innovative, patent pending device for stabilometric analysis.


Analysing the posture of a person may represent common language for medical disciplines, because in this case the person is examined in overall terms

This diagnostic process may therefore be added to by this approach, always with a view to better defining a prevention or cure programme, possibly also by means of multi-disciplinary treatment.

One keyword is “Lifestyle” that in today's world is characterised by more sedentary activity, bad habits and a lack of physical exercise,resulting in greater social costs.

Observing incorrect postural behaviour may, therefore, provide confirmation and act as an incentive for developing prevention strategies from the early developmental age groups.

Once acquisition of the photographs of the body has been completed, the person is asked to move to the PODATA device to acquire the photo of the soles of their feet and for a stabilometric analysis. 

The person must stand upright, with their feet positioned as they please on two glass top plates.  The person looks ahead with their arms straight at their sides.

The photo can now be acquired using the built-in camera, and the consequent detection of the type of feet, whether normal, flat or cavus. 

This photo is then added to the other photos acquired during the examination on the same day.


Initial concept:

The body weight is distributed to the two feet, and is especially distributed to three points on each foot: the first metatarsal, the fourth metatarsal, and the heel.  

According to the "6 rule" of French biomechanical engineer KAPANDJI, when 6 kg is applied to the astragalus, 1 kg is loaded onto the antero-external support, 2 kg on the antero-internal support, and 3 kg on the heel.  This means that the heels support half the body weight, that is 17%, 33% and 50% respectively.

Preliminary operations:

At this point the person being examined gets onto the PODATA and is asked to stay still in the same conditions as previously, that is, looking ahead, arms straight at the sides, feet each standing on a glass top plate, freely and naturally.

The GPS 5.0 software positions the six load cells at the pre-set points under each foot.  This movement of the load cells guarantees repeatability of the measurements, even at a later stage.

The stabilometric test  can be done under various "examination conditions", in looking for afferents that affect the person's postural behaviour.  The session can therefore be repeated with the eyes open, eyes closed, looking to the right, looking to the left, teeth clamped, mouth closed, mouth open, head bend back, head tilted to the right, and head tilted to the left.  There are 10 examination conditions, and they can also be personalised.  Let's choose the EYES OPEN examination conditions, for example.

Once these tasks have been done, you can proceed with examining the person's stability, and start recording.


The results obtained include, first and foremost:  1) Projection of the person's barycentre onto the floor, 2) dynamic recording of that projection during the examination period, 3) the location and dynamics of the barycentre for each foot, 4) the distribution of the load between the right and left feet, and 5) distribution of the load between the 1st metatarsal, 5th metatarsal, and heel.

Further numerical values are measured in relation to the graph of the so-called "ball" and the Fourier analysis.  This data is currently being studied by universities to determine the implications and related meaning.

Graphic representation of the feet with the relevant symbols shown above constitutes the result of the observation of a sample of more than 1000 children and 2000 adults during 2011, broken down by gender and age group, all belonging to the Italian population.

 The result of the university study therefore led to normality values being defined for each of the parameters presented, as well as an acceptable deviation spectrum, according to statistical distribution in percentiles.  Results that were lower than the third percentile or higher than the 97th percentile, were therefore taken as being not normal.

Once all information necessary about the patient’s history have been collected, the examination can start. It is important to analyse initial posture before modifying any afferent pathways.
