We previously reported on preparatory study for a new dynamic equilibrium examination, the "Foulage test" using normal subjects. This is a unique stepping test on a stabilometer, keeping both toes constantly in contact with the plate and lifting up only the heels alternately, BPM 120, 60 seconds, 120 steps, with eyes open and closed. The total locus length (L) and the environed area (A) are measured. We found a new equilibrium parameter FT (=120A/L). In order to evaluate how FT can measure body sway, we applied this examination to patients with dizziness. Two hundred forty six patients, 60 men, 186 women, 14 to 87 years old, mean of age was 59.2, were tested. According to the sway level, patients were classified into 4 groups from stable "level 0" to almost falling "level 3". We analyzed FT and sway level of each group. FT increased gradually (p<0.05 Steel-Dwass test) concomitantly with the sway level. This study may establish the Foulage test as a possible new dynamic equilibrium examination.
