Literature about normal parameters of Craniocorpography (CCG) is scant and poorly documented. Its results are variable according to the series. Our aim is to reach a criteria of normality for CCG in our reference population. We have prospectively made Romberg and Unterberger tests to 72 healthy volunteers (mean age 34.7 years old, SD 17.07, 55.6% men) using a computerized method of measurement and making its estimation by means of a statistical model widely accepted. All the studied variables observe the conditions of Gaussian distribution. The normal limits for lateral and antero-posterior oscillation were 9 centimeters, 12 centimeters for lateral sway and 59 degrees to the right and 46 degrees to the left for angular deviation. The computerized method of analysis has facilitated the detection of the limits of the light tracings, which together with the careful design of our study guarantees the validity of the results.
