The table shows the identification number, name, and abbreviation. Parameters are clustered on categories such as displacement on mediolateral direction, displacement on anteroposterior direction, displacement on resultant direction, area, 95% ellipsoid, Romberg coefficient, path/area, covariance, velocity on mediolateral direction, velocity on anteroposterior direction, velocity on resultant direction, the base of support, and time.
