It is well recognized that the relative position of the center of mass (pCOM)with respect to the base of support (BOS) is a determining factor in themaintenance of balance. However, during gait the dynamic nature of the BOS isnot well defined and in most studies is completely ignored. Prior work tends tofocus on the variability in the position of the center of mass (COM) withrespect to the laboratory reference frame to attempt to quantify dynamicbalance. We propose a modified method whereby the position of the COM in anend-effector based coordinate system may be used as an improved estimate ofthreat to balance during gait. The distance (DN) of the projection of the COM(pCOM) from the reference axis, normalized by half the foot length forinter-subject comparison, is an estimate of the gravitational moment arm. Itcan be shown that in concordance with theory, balance impaired subjects withspastic cerebral palsy (CP) have a larger DN than their typically developingpeers. Furthermore, when compared with variational methods, DN shows betterdiscriminative ability in characterizing groups.
