Specifications of the clinical stabilometry platform
Latin posturologists unanimously recognize and accept that the normalization of stabilometry can only be based on decisions often
arbitrar y . These specifications of the standard stabilometry platform, ADAP-N ormes2013, represent the first series of those decisions,
admittedly arbitrary but made after a discussion with the French and Russian platform manufacturers, in Paris on 13 December 2007.

The figure 1 shows the normal operating range with
minimum and maximum values.
The gure 2 shows the storage temperature range.
Average time of good uptime
The manufacturer will specify the me interval between
Validation tests Procedures
The Parre’s test procedure(1) may be used to validate the
compliance of the plaorm with the specicaons.
Center of gravity
The calculaon of the posion of the center of gravity must
comply with the sources, provided free by the ADAP.(2)
Not because this calculaon would be the best, but because
we need to work on the same values.
This calculaon should use the height of the subject and
the form factor: 0.659, not because it would be the best, but
because we need to work on the same values.(3)
Manufacturers may provide all stabilometric parameters
they want. But ADAP has dened some parameters described
in a data basis; the soware provided by manufacturers must
produce exactly the same values of these parameters as those
given in the data basis. (The data basis will be published later).
Transfer of the stabilometric signal
The coordinates of the center of pressure of each
recording must be available for anyone. At the end of the
le, the rst ve tags will give these indicaons, in this order
and these units:
1) Height (cm),
2) Weight (Kg),
3) Shoe size (French),
5) Age (Years)
NON MANDATORY APPENDIX
Weight of the skirt of the platform
The error due to the weight of the skirt of the plaorm
is to be corrected, simply by mulplying the signal by the
/1 Pj Ps+
where Pj is the weight of the skirt and Ps is the subject’s weight.

Height of the platform
It could be a good idea reducing the distance between the
plane of the gauges and the superior plane of the plaorm.(4)

CERTIFICATE OF CONFORMITY
Direcve 93/42 / EEC and its Annexes of the Council of
Europe of 14 June 1993(5) provides that: “The EC declaraon
of conformity is the procedure whereby the manufacturer
ensures and declares that the products concerned meet the
provisions of the Direcve ... “
This obligaon and its consequences are therefore imposed
to the builders of stabilometric platforms conform to the
specifications ADAP2013 (considered as Medical Devices,
Class 1 m, with measuring funcon), parcularly in its Annexes
VI and X (point 3). It belongs to them taking all technical,
industrial, organizaonal and contractual decisions needed
to cerfy the proper compliance of their plaorms to these
