Abstract

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.

Highlights

► 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.
