Conflict of interest statement



Several statements on the still debated issue of stabilometry standardization were agreed upon by the ISPGR Standardization Committee.

A set of metrological characteristics for stabilometric platforms was defined.

Relying both on practice and experimental verification it was agreed that, to obtain appropriate accuracy and sensitivity in the Romberg Test:

The acquisition interval should not be less than 25 s.

The sampling frequency should be at least 50 Hz.

After careful consideration it was decided that the recommendations made in the previous Standardization proposal in 1983 regarding environmental conditions should be maintained.


► Static Stabilometry lacks standardization criteria needed for reliable consensus diagnostics in clinical practice. ► Instead of defining Force Platform Design Characteristics, Technical Performances for the instrumentally derived parameters should be set. ► Environmental test conditions as set forth by previous recommendations are confirmed. ► Data Acquisition Interval should not be less than 25 s. ► Data Acquisition Sampling Frequency should not be less than 50 Hz.
