Clinical stabilometry standardization: basic definitions--acquisition interval--sampling frequency.

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.
