Date Oct. 27, 1983.In the diagnostic evaluation of the measurement of head rotations for the functional examination of the cervical portion of the spine and the upper dorsal column it is to be noted that the head rotates not only with reference to that axial system which corresponds to the measuring system arranged between the holder and the supporting device, but also performs a three-dimensional movement in space. When tilting the head, e.g., the same not only rotates about a horizontal, frontal axis (parallel ear-to-ear) but also moves forward and downward. Even more complex are rotary or lateral tilting movements of the head which, beyond a certain extend of displacement, proceed only with a three-dimensional motion of the head. Yet the rotations of the head in a broader sense, including the ancillary movements referred to, are what permits more accurate conclusions as to the function of the spine. Analogous conditions apply to other sequences of movement with multijointed motion progressions, e.g. of the extremities. It is therefore essential to the invention that not only the rotary movements of the holder are measured by the measuring system arranged between the holder and the supporting device but that also the motion of this measuring system or the holder in space is taken into consideration in the measurement or in the evaluation of the measuring results. This can be done, preferably, by an additional measuring system arranged, say, in the region of the supporting device for detecting the movements of the holder in space and/or mathematically in the evaluation by a data processor. |
