Mathematical model of Bcg: comparison of ULF and DB.
The DB and ULF accelerations are expressed in terms of arbitary time-dependent forces acting on the heart and on the body frame. For an appropriate choice of these forces, a normal DB and ULF and acceleration Bcg is reproduced. By reducing the coupling, between the subject and platform, the DB Bcg is changed successively until it is identical with the ULF Bcg.
