IPC: A61B5/11
Filed: 1998-03-07
Abstract: A method for evaluating a head and trunk movement pattern of a subject includes configuring a plurality of markers to move together with the body of a subject. For each of the plurality of markers, a locus curve in three-dimensional space is detected as a function of time and the locus curve is stored as a data field of a measured data record that is common to the plurality of markers. The movement pattern of the body of the subject is characterized using characteristic variables derived from the measured data record. Reference variables are derived from a stored plurality of reference data records. Each of the characteristic variables is compared with the reference variables derived from the stored reference data records. Each of the characteristic variables is derived from a projection of the locus curve of at least one of the markers onto one of the three datum planes of a Cartesian coordinate system. It is thus possible to interpret the evaluated kinetic pattern and use this information to provide a diagnostic of the basic clinical picture, especially following psychic, psychosomatic and/or neurological disorders.
